Hiper Type-R Modular Blue Line 580W PSU Review
MrIcee2 writes "XtremeResources today has on the test bench the Hiper Type-R Modular Blue Line 580W Power Supply Unit . Our European Senior Reviewer Grace evaluates the high end modular Power Supply Unit solution powering her Intel P4 3.73 EE, Asus P5AD2-E premium based test bench. Read along as she determines the flexibilty this unit offers in it's modular construction, and takes a look inside to see what make this unit the powerhouse that it is.
"Most users underestimate the necessity of a good, reliable and high quality power supply unit. They usually do not understand that it is the driving force for the whole system and it can affect reliability and stability substantially. An inadequate power supply unit will cause instability of the system at best, it may overload and burn out attached components in the worst case scenario. Hiper (High Performance Group) recently released the Type-R modular blue line HPU-4B580 power supply unit, which is competitively priced and claims to be able to offer everyone what they want and require. Hiper was nice enough to have us take a look at the unit, so we will shortly know if it can stand up to its claims."
I can see why they call it the "Blue" line!
Sometimes we see... you know... exciting hardware, or groups of hardware... but a single power supply? WOW!
This PSU is amazing!!!!11 I use it to power my refrigerator, microwave, AND have enough juice left to run a small space heater in the winter... shweeet jesus!

Must be a power supply for all the ricers!
Only to the extent that it, you know, powers the board. *rolling eyes*
It's all just electrons, and any power supply large enough will power your computing needs. I suppose painting it metallic blue is cool because, of course, it's inside the case where looks really matter.
Frankly, it doesn't come with the Type-R sticker, so it is only Type-R in name only. Lacking in that extra 5hp, I think we are looking at a dud.
Might as well call it the Hiper Civic.
Does it come with a free fusion plant to offset the power bills?

So do we have to use a K&N air filter for the air intake to maximize the power?
I'm sure some neon lights will help too.

It seems to me that one of the whole points of digital is that as long as the power rails are above some sufficient level of performance, any improvement in performance is pointless. Power supply noise isn't an issue below some critical value. This reminds me of the crooks who try to sell people on $100 digital audio fiber optic cable for "higher fidelity."
Why am I not surprised to see X-Treme tech covering a Type-R anything?
Can't these guys come up with any more friggin' letters than X and R? =)
Young punks, get off my lawn.
Lost at C:>. Found at C.
...but does it come with a cool type-r sticker for my case?
Does the exhaust fan use VTEC?
I don't know whether it was a hoax or not, but I remember reading that utility companies look for spikes in power consumption as evidence of indoor marijuana growing. Whether or not 580w would be over this threshold, I'm not sure.
With a name like that, how can't it sell?
Let me know when K-Mart is running a "blue light" special on this power suppy. I'm too cheap to pay full retail. :P
Meh...it's an art piece, for sure. But I've had excellent luck with nice, inexpensive Sparkle power supplies from Newegg.
I think more users underestimate the value of a half-decent surge protector, and many of those that think they are using one are actually using a plain power strip.
On the power rating, the problems I've run into in the past is finding the power consumption ratings of all the devices I expect to use, and how much power is used from the respective voltage rails.

This PSU is a Good Thing.
After buying an Ultra X-Connect last year, there's no way I'd be able to go back to a conventional power supply. I love the modular design.
It's about time someone else came out with a modular PSU. Hopefully, Ultra and Hiper will be able to push modular power supplies to the point where they completely drive conventional crap out of the market.

Why does the PSU have to be internal?
Why can't it be external like for laptops. That way heat isn't dissipated inside the computer case.
Can someone straighen me out here?
The Internet is full. Go Away!!!
First of all, wtf is with that name? All it needs is a few more Xs for Xtreme.
Anyway, thanks for a bunch of pictures of the PSU without actually telling me anything. If you want a real review of PSUs, head over ot X-bit labs. All of their reviews contain actual power data with power draw vs rated voltage graphs and scope readings of rail fluctuations. And one picture of the PSU if you actually care.
I think they should have made comparisons with other cheaper and competing high brand PSUs, otherwise there's no point in giving those readings on the PC Probe software.
Performance would seem more important to me than the country the steel came from.
And we're supposed to believe that someone is powering a P4 3.73GHz with only a 580W power supply?
In all seriousness, I have to be suspect of a title like "European Senior Reviewer" from a website that has the 'word' "Xtreme" four times in the title image alone (and not just because most hardware savvy people are using either Athlon64s or Pentium-M's). I guess it's cool, or something, to have an xtreme power supply for the extremely power-hungry PIV. Or maybe it was the metallic blue finish--always an important factor when considering the relative merits of competing power supplies.
Reminds me of that group of idiot truck-driving teenagers in Harold and Kumar go to White Castle. "That was so not extreme."
Cool movie.
Computer Science is no more about computers than astronomy is about telescopes. --E. W. Dijkstra
These guys should learn how to properly test PSs from X-bit labs http://www.xbitlabs.com./
"I think more users underestimate the value of a half-decent surge protector, and many of those that think they are using one are actually using a plain power strip."
Those cheap consumer surge protectors give a false sense of protection. A whole house surge protector/ power conditioner with excellent grounding is much better.
"On the power rating, the problems I've run into in the past is finding the power consumption ratings of all the devices I expect to use, and how much power is used from the respective voltage rails."
That's what a good meter's for.
Hard to take something seriously when it's called 'Hiper' is it supposed to my 'Hyper-Mega-Awesome' or 'Hipper' or what are they going for here? Personally though, you can't go wrong with something from PC P&C
Your hair look like poop, Bob! - Wanker.
So putting this Type-R part will make my computer faster, right?
THis is a dual core Intel chip and a top end graphics card... Lets see, 580W * 24 * 365 * $0.17/KW*Hr (CA rates) = $863.74/yr
Not bad. Add in what it takes to cool the room it's in, large fans, or AC, so double that.
So only about $1,700/year to power that new dual core Intel system. Rural China will be swarming with these in no time!!!

There's a company listing:
HIPER ENTERPRISE CO LTD
E224709
5TH FL
79 MIN-SHENG EAST RD, SEC 4
TAIPEI 105, TAIWAN
But they have no listings for PC power supplies. They're listed as a maker of circuit and battery chargers. The Hiper web site says they're in Guangdong province, China. So this may be a different company.
What this outfit seems to do is buy power supplies and repackage them. But, because they change the wiring, fan, and connectors, any certification applying to the original power supply is now invalid. Hiper should have run their power supplies through UL certification under their own name. They didn't.
This matters. If you read serious reviews of power supplies, where they're connected to a dummy load and run at their rated power, you find that many power supplies won't deliver their rated power. Some catch fire under full load.
When you look at the loser power supplies in those reviews, the ones that burn up are never in the UL database. And most of the ones that work properly under full load are.
UL loads the things up to full load at the top end of their temperature range and runs them for a few days. That's all. UL certification only means that it won't catch fire. That's a good first step, These guys didn't take it.
Laptops actually only have a portion of the power supply outside the case. They convert to 28V, for example. Converting to a low voltage like 3.3V outside the case is inefficient, for the same reason that houses don't use 10V power. If you have a device that needs 330W, it can take 12A at 28V or 100A at 3.3V. Now, let's consider the resistance in the wires. If they are 0.01 ohm/foot, and you have 1 foot of wire, then you will lose 0.01*12 or 0.12V if you use 28V , or you will lose 0.01*100 or 1V at the 3.3V input. Now, at 28V, you lost 0.5% of your power. At 3.3V you lost 30%. And this is over one foot. If the wire is 3 foot, it gets far worse. So it is smart to run high voltage as much of the way as possible, and the low voltage runs should be short. Again, this is the same to your house. Laptops get away with this because they use less power, less power is less power lost. And as I said, they don't put the power supply outside the machine, only part of the power supply. It might be smart to put the rectification (AC->DC conversion) outside the case, because it doesn't reduce the voltage and it does generate heat. But it really won't save you much. On a final note, connectors have a voltage drop of their own, so it really isn't smart to put extra connectors in the low voltage outputs from the power supply. New power supplies are doing this, because it sells units, but it will cost you in the end in lost efficiency and lower reliability (connectors can break).

It seems like every PSU related story on Slashdot is really some sort of a direct sales-pitch.
Oh - and 580 watts?! That'll go really well for the average geek's apartment where they might only have two 1800 watt circuits. Add in the monitor, air conditioner (obviously necessary if you work around today's machines), a television or stereo of some sort, some lighting, routers, cable modems, telephones and a few other devices and the average geek isn't going to have the available power flow to keep his house lit.
"Type-R" is well-known among the racing enthusiasts, as a tuned up version of the original platform to its maximum output
Nope. Actually, I know it to be mostly used for badge engineering- aka posturing.
There's a strong preference among many car enthusiasts for vehicles that just don't stand out. We call them "sleepers", and their performance and subtlety speak for themselves.
For example, with just a litre more displacement- helps to have 5 cylinders instead of 4) and a turbo- I've got around 150-180 more HP than them. A manual transmission (don't laugh, half the ricers drive automatics), all wheel drive, and not a single badge on the car except rings on the trunklid and 'quattro' in the front grille.
Kicker? Blue book value is probably half to a third what a new base-price honda coupe costs. Granted repairs are a little more common, but in the end, for some of us, the occasional hassle is worth it :-)
Please help metamoderate.
Before you spend your hard-eanred cash on such fancy item, be sure to go to http://www.jscustompcs.com/power_supply/ and calculate your PSU requirements, which will likely inform you that, unless you're in the exceptionally rare minority, far less expensive PSUs with less wattage will more than suffice.
Well, it looks pretty enough. Not a single mention as to any of the important stats, however. Modern hardware sucks up an incredible amount to juice, and this review did not mention how many amps on each rail, or decibels when the PS was running under load.
Been burned on crappy 'high wattage' power supplies before. Worth reading the Watts don't mean Jack sticky and a few others in the form if you are looking to build a SLI system.
Type-R... It was bad enough to buy a DFI 'LanParty UT SLI-DR' board, of which only three letters told me anything about it. What is with these marketing people?
+++ UGUCAUCGUAUUUCU
This is supposed to be a review of high-end power supply specs and it never mentions ripple? How about overvoltage protection? Aging? Brownout or surge protection? So how stable is the output of this supply? Real stable. Oh, OK.
... may blow up". Yeah, I think I saw this on Star Trek last week. If they would only stop making those cheap supplies out of TNT.
Then there are statements like this in the review: "Cheap power supply units
No price anywhere. Can it unseat the competition? Who knows?
The use of Honda's unrelated Type-R performance label tells me they are appealing to quality by association to something they deserve no merit for.
The review site talks up the need for a beefy PSU, but shows no methodical testing whatsoever.
Seems to me the editors are a bit detached from if not journalistic integrity, at least some base duty they have to give us relevant stories. This is a clue to the sort of fuzzy logic is used when choosing submissions. Choices seem related more to pandering than genuine identification with the interests of slashdot readers.
No wonder they got rid of John Katz, lest it be too obvious. He writes for MSN now.
I couldn't find a US reseller though.
Was the most expensive one:
Topower 420
It was in my gaming PC to protect the expensive components. I turn that thing on once a week at best. I also have a no-name PSU that cost me $30 with the case that has been on for the past five years with zero problems. Go figure.
Yeah, it's a pretty box that has a big number by the word Watt.
I don't know this power supply and it may be solid. But one thing most PSU manufacturer's keep hidden is the temperature that these's PSU are tested at. Some boast Watts of over 500, but at temperatures of 25 C.
The hotter your PC is, the lower the Watts your PSU puts out. It was something I learned before by nVidia's latest videocard.
I went with PC Power and Cooling for the reason that they display the Watts AND the temperature that it runs at.
PC Power and Cooling Turbo 510: 510W at 50 C
Honey, what did the kids do with my SATA power cabels? F*&K it anyway....
They didn't get UL listed because (A) it costs money and time, neither of which a fly-by-night company is willing to invest; (B) it probably wouldn't've got past the UL engineers.
If this PSU catches fire and burns your house down, your insurance company will not cover it because you are using unlisted electrical appliances. No joke, son.
...but the build quality is awful. Check this image: cramped cables (without need), restricted airflow, solder joints holding weight, bent circuit boards, minuscle heatsinks, panel mount parts glued with silicone... no wonder it needs two fans (and one is 120mm)!!!
Come on, i know ATX power supplies are limited in size, but i have an "el-cheapo" Chinese 300w PSU which works like a charm and it's much better designed and built. It looks cool, and it seems that it's very good at regulating the output voltages, but you can get that elsewhere without the glitz. No mention of it's price either.
To be honest, i wouldn't want that powering my PC.
I had all sorts of hell with my athelon 64 booting sometimes, locking up others. Rebooting randomly, and basically being a big pain in the butt. Then I replaced the power supply with a non-cheapo unit, and put a battery backup on the system and haven't had a problem since. I've also heard similar tales from other folks.
The use of Honda's unrelated Type-R performance label tells me they are appealing to quality by association to something they deserve no merit for.
Perhaps you could just take a regular power supply and put a "Type R" sticker on it. The kid down the street put a Type R sticker on his Toyota, and he claims the sticker alone makes it faster.
If you really wanted maximum performance from your power supply, you have to put a bunch of Japanese characters all over the power supply, as well as do a really bad job of placing it lower in your computer's case. Also, you'd have to solder a giant coffee can to the cooling fan, because that makes it goes faster too.
The Internet is generally stupid
I trust my 465w a-pfc enermax anytime over some slashvertised psu with -Rs in its name from sites with Xs in its name. whatever. Anyways, someone who uses such cpus and don't have the clue to take care of a proper psu, they deserve what they end up with.
I am putting myself to the fullest possible use, which is all I can think that any conscious entity can ever hope to do.
I have never heard of Hiper before. Anyway, I decided to see how much this PS costed.. and I couldn't find it for sale anywhere.
Considering most cases come with a decent power supply, there isn't much room for expensive power supplies.
Gotta have the daily dose of capitalism!
It's a Bagel.
I recently upgraded my graphics card to a Gigabyte 6600GT. When I had instability issues the first things blamed were heat and PSU. Heat was a problem, but not the central one. Cleaning out the heatsink and adding a case fan was worth doing. However it I think it was an issue with drivers and motherboard. (Turning off AGP direct writes seems to be the thing that fixed my game and system freezes).
However note that I am running the following on a generic 400W unit.
P4 2.4 clocked up to 2.6
1 Gig memory
3 hard disks
2 optical drives
6600GT
Geforce 440MX PCI
SB Live
USB 5 port card
Extension board for SATA
Case fan
All stuffed into a mini tower
4 external 4 port USB hubs
Memory card reader
Joysticks, gamepads and driving wheel
I also have 2 external drives, one hooked up USB and the other SATA but of course these aren't powered by the PSU.
I look at the calculators out there and I should be running a 500W, but the fact is not everything gets used at the same time, and the system copes quite well.
When I say I run stable I'm talking marathon sessions of FS2004 3 screen or games like the incredibles (which was my best test for freezes).
I do have some issues with the USB occassionally. Devices, particularly the card readers start generating errors in the system log. I don't know if that's a power issue or just XP and crappy drivers. USB 2 support on my motherboard doesn't seem to be the best.
When I buy my next system I will go for a better brand PSU, however I wonder how much of this "you need a good PSU" stuff is hype drummed up by the PSU manufacturers. I certainly won't be upgrading the PSU on my current machine.
Of course I'm not running a 6800GT or a newer processor so perhaps that's what would make the biggest difference.
These posts express my own personal views, not those of my employer
I thought all these die shrinks was supposed to *decrease* power consumption... IMHO this is just getting out of hand. My PC has a 350 watt supply (old Barton 2500+ w/ nVidia 4200 card), but i'm just not into building a A64/x800/ 500+ watt monster. I'd repackage what i have into a SFF box, and get a better card. My Mac Mini only draws 20 watts at the plug, and it makes a difference on the power bill not to run the PC. What next...a PC that draws as much as a hair drier? All that power gets converted to heat... Seriously...i'm looking for lower power and equal performance.
the modular cords really do help clear up the clutter (although I wish they included two PCI-E cords just in case someone needs them for SLI), and the variable fan speed capabilities of the psu keeps it (and other fans) fairly quiet even in my boomy Coolermaster case.

First, because of the shitty way that digital audio is transmitted, cables actually can make a difference, at least in the copper realm. Not sure about fibre, I'm inclined to believe not but who knows. At any rate, how can there be any problems with digital you ask? Well because the way the elected to do transmission is not only data, but clock as well down the wire. So this means that not only is if a bit is 1 or 0 important, but WHEN that bit happens is equally important.
The phenomena of a clock being irregular is called jitter and it's quite audible. However it's a funynt hing, you can fuck up a DAT unit so that it jitters so bad that a DAC has trouble locking on the signal and man will you hear it, it'll be awful. But, if you use another DAT to make a digital copy, it'll come out perfect, since there you are just concerned with the data, not the clock (well that's not entirely true, but the clock is stored globally).
So what can happen with a cable of improper impedeance espically in a noisy environment is that the changes in voltage introduce jitter in to the signal, and thus cause distortion. Now I don't htink this happens with optical signals, but I don't know, I suppose it could. Now please don't mistake this for meaning you need some special audiophile cable, but there can be a difference between some random RCA cable and a properly shielded 75 ohm cable made for S/PDIF.
As for PSUs, yes you get better performance from a better PSU. Not better speed wise, better stability wise. You get lots of stability problems from a shitty PSU. You have to remember that ene if you don't load down your PSU (shitty PSUs don't perform under load) line voltage isn't stable. At best it's mildy unstable, at worst it can be really unstable. Well a good PSU can provide stable output even during voltage sags or spikes. Shitty ones will change the output voltage, which is highly likely to cause a crash.
Now while I wouldn't trust something like this to be high end, it looks like so much hype, it really is a buying concern. Don't get some brand X POS, spend the money to get a real quality powersupply. I'm a fan of Antec and Fotron/Sparkle personally. If you want something really solid, it's hard to beat PC Power and Cooling but they tend to be on the loud and expensive side. Good for servers though.
At any rate, there IS a measureable difference between good and bad power supplies. There's also the question of what happens in the event of a failure. Suppose it over heats or the output limits are exceeded, what's it do? A good one will cut power and not cause a problem. Bad ones often catch fire.

The lines:
the spin of a HDD is louder than the power supply fans and will negate any noise coming from it unless loaded heavily. Another nice feature is that the 80mm fan keeps spinning after you shut down the system for a few minutes
Are enough to negate any priase from the reviewer in my eyes.
What's he saying, it's quieter than an HDD!?! I should bloody well hope so, those things are beasts. And they only make a noise when they're being very actively used, while PSU will whirr away in the background.
The fact the guy says he loves quiet, then goes on to say that this PSU actually KEEPS making noise when it goes off, is an infuriating spin on the matter.

As you would have found if you'd clicked on the company link in the article, the company name is "High Performance PC LTD". Now try searching the UL database again (look for file E245388), and post a correction. Moderators may want to do the same thing.
I'm pretty tired of hearing this claim over and over again... Anyone want to try and provide some actual proof?
I've owned my share of both Enermax power supplies, and $10 no-name "500watt" power supplies, and I haven't had reliability problems with any of them, even with extremely long uptimes, and months of tripple-digit ambient tempuratures.
I suspect this myth has just stayed around from the good old days of the 90 watt power supplies, being installed in systems that have a peak power draw higher than that... It's a non-issue these days because the $10 power supplies are rated at 500watts or more, which is better than double the power most people will ever need. It's getting to be less and less true as time progresses, because processors are getting lower and lower power (though nortbridges are drawing significantly more power, unfortunately).

Get a Seasonic S12-430 instead. Quiet (20dbA/1m below 150W), cool (less than 6C difference between intake and output), efficent (over 80%), friendly to the grid (active PFC), and, perhaps most importantly, UL certified.
I have the older Super Tornado 300W, and it's excellent. All the power I need to keep my system running without a lot of noise or heat.
Seasonic knows what they're doing.
any chance Grace is reveiwing this topless?...i for one am reviewing it bottomless...
Before you ruch out an d buy this PSU, take a look at Antec's NeoPower 480W. I doubt that any other PSU company makes as good PSU's as Antec. See Specifications for a VERY detailed spec. of the PSU, nothing is let out. Antec pride them self of relieable PSU's and they have good reason for that. Look at the measured Ripple Voltage.
Amen. And if you're a competant rider, you could out corner the civic at every turn too. I wish I didn't let my mod points expire.

Looking at all those connectors on the case, you gotta give them credit for findong a use for all those old locking-ring type CB Radio microphone plugs and jacks left over from the late 1970's and early 1980's.
That should be "its" not "it's".
I could quote a normative reference at you, but I can't be bothered to find it right now.
Trust me, I'm right on this one.
For crying out loud, a PSU ad as news? I mean it's not even hyped - i'd understand a new Mac review (it's a whole system) or a report on sun's latest monster system, but a PSU?? Why don't we have then a full featured articles on new EzGripp ThumbScrews 3000? /. - Either "editor" or "quality" are becoming foreign terms for the /. operators.
P.S. The anti-script image is so l33t now, it took me some 30 seconds to dechiper. I guess i'm a half-script.

I find it interesting that the reviewer here makes absolutely no mention of price. He says twice on the first page that it is "affordable" however there is no dollar amount listed. I researched it, and it looks as if it has a street price of around $130. I would hardly call that "affordable." Granted there are more expensive power supplies around, but considering that I can buy a "premium" power supply at my local computer store for $80, I wouldn't be throwing around the word "affordable" like that, especially when he chooses not to list the price in the article.

What do you see wrong with this pic? Check out the heatshrink on the bundle of lines next to the Toriods. Loose... it isn't even shrunken properly. Then, check out the main PCB to the left of the silver screw on the lower left of the pic, right by the IC... the board is BENT!! HELLOOOO!! This is a shoddy piece of sh!t!

"An employee suggested to me that we use this power supply for a few offices here as an evaluation. [...] I made the employee remove the Hiper from the offices and lets just say he's not with us anymore."
You kicked an employee out because an evaluation that he suggested didn't work out? That is, pardon my French, completely fucked. The whole reason you do evaluations is so that you don't end up in a position where new products put people's job on the line.
Apart from anything else, from now on if an employee suddenly discovers a product that at a stroke will double productivity, halve costs and save small kittens from drowning, do you think they're going to tell you about it? No, they're going to hide behind conformity, in the hope that that way they'll keep their jobs.
Congrats, you've singlehandedly halted improvement of your company's computing infrastructure. I'm sure it'll mean far less trouble for you, right up to the point where an innovative competitor buys you up and fires everyone.
We recently had heard in the office over one of the Yellow Machine that's made by Anthology Solutions.
It was an example, not a case study. If you think that this isn't a problem, why are there multiple parallel +3.3V and +5V wires from your power supply to your motherboard? Over only 18 inches? Whatever drop I have right now, if you extend the cable to 5 feet instead of 18 inches, and go from multiple parallel wires to a single wire for each voltage (you can't have a 1" bundle across the floor), you'll end up losing 15x as much power (assuming about 3x farther and 5x parallel wires right now) as you do with the power supply in the case. And, as an added note, often your power supply is running a re-regulating switching power supply. These things have massive input currents, well north of 5A. I'd love to see smaller supplies. But look at the current situation. My 6800 Ultra video card requires TWO hard drive power connectors into it. Why? The vast majority of power supplies have only one circuit of power for +12V each of and +5V (and virtually all when the card was made, as the number is rising). Yet the instructions say you need to put plugs from two different strands into the card. Why? Because the drop in those power cables is too large for the currents they draw. They need parallel wiring to halve the drop. So what is going to happen if the power supply is now 3x farther away? I'll need 6 wires. Big portions of the power supply must remain in the case right now. And likely forever.
