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.

"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."

      My computer uses exactly 40 Watts under full load, which means playing HL2 at a decent resolution. The PSU is fanless, noiseless and can deliver 60W sustained power, although that's never needed if my power meter reads correctly. The computer has a heat pipe system, transporting CPU and GPU heat to a single 8x8cm heatsink with a small temperature controlled fan, exhausting directly to outside air. This fan switches off, so the system is, except for a barely noticeable HDD noise, extremely silent, whenever convection cooling is sufficient, e.g. system is less than half-loaded and ambient temperatures are below 25 degrees Celsius, for example while writing /.-comments and surfing the web ATM. The CPU core frequency adapts in 4-step granularity to current computing power needs, so it saves more power and exhausts less heat while the CPU is waiting for me typing comments in a browser window. Typical low-power intake is about 25W, so the PSU is barely above room temperature.

      The system had cost me 15 percent more as an equally powerful (in terms of computing power) but 7 times as energy consuming system. And the best (hehe): it has an integrated UPS with a backup capacity of 2 to 4 hours, depending on load. Did I mention the flatscreen built in for improved portability to LAN-parties?

      Welcome to the world of current notebooks. I will never go back to a desktop rig, as long as those are weighing more than 4kgs, consume more than 200W while writing mails and surfing the web and produce more noise than a vacuum cleaner.

      I don't know why PC manufactures haven't caught up to the current standards in power saving and noise reduction. Traditional desktop systems are IMHO not that much cheaper to offset their disadvantages, compared to notebooks. When I browse sites like Newegg, I conclude the price premium for notebooks is less than 15 percent, taking the integrated 15-17 inch TFT screen into account. The only thing notebooks lack is HDD space and speed. Most have 4800 upm ones and their capacity is 100GB at max. Capacity is offset by cheap USB-HDs if needed and speed is currently catching up with the first 7200 upm HDs appearing for the 2,5" form factor. Noise will then be an issue again, though, I fear.

    When a power supply is listed as "XYZ watts," most users just assume that either it's big enough or it isn't. But a 550 watt power supply that only supplies 25a on the 5v rail giving the rest to 12v is going to flame out or melt wires eventually if your mainboard runs two CPUs on its 5v line.

    You clearly have no idea how a) power supplies work and b) how marijuana growing works.

    a) 580watt is it's rated maximum power output, on all three voltage rails combined. There are individual maximums for each voltage rail, so you would have to be exactly at each of those to be drawing the full 580 watts at any given time. You never max them all out, you max one out, typically the 5v. Point number two: 580 watts is its maximum power output. After that it may very well burn out or catch fire or whatever. Realistically if you're drawing anywhere near 580 watts you're going to be getting a very unstable system, because at that kind of output it cannot keep a reliable stream of power coming out. For a good power supply, you never want to exceed two thirds of its rated output. For a cheap powersupply, cut the rated output in half, or even to a third. You don't want a maximum sustained load above that. Third point: In all realistic use, PC powersupplies only approach their maximum at startup, when everything (hard drives, fans) is spinning up and all the capacitors are filling, etc.

    b) Even modestly sized marijuana grow-ops (disclaimer: I am not one, I don't even smoke pot, so take this with a grain of salt) use absolutely ridiculous amounts of electricity. The grow-lights alone they use are typically 1 or 2 KILOwatts each, and if you think they're using only one or two lights you're crazy. The temperature control also uses a hell of a lot of electricity for hydroponics. I have 7 computers in my house, two of them very hefty servers, and all of them with at least 340watt power supplies. My power usage on my last bill was 671 kilowatt-hours for a month. A grow-op will use that much in a week, or even days.

  15. because it isn't efficient... by YesIAmAScript · · Score: 2, Informative

    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).

      Nope. Actually, "Type-R" has a very specific meaning -- it's a trademark that Honda uses several of its cars to denote a more highly tuned model, such as an Integra Type-R. The ITR was brought to the US in 1997, featuring a more powerful engine, a different gearbox, and less frills to reduce weight (such as air conditioning and insulation), among other changes. This is not dissimilar to other cars from other brands, such as the Mazda Miata R, the BMW M3 LTW, and the Chevy Corvette Z06. Honda also has a Type-S designation for other cars that sits between the regular versions and the premium enthusiast version.

      However, car/pop culture being what it is, the branding has been diluted with lots of wanna-bes and suddenly Type-R stickers and badges started appearing on all kinds of cars, notably non Type-R Hondas, but on other makes and models as well. For example, Accord Type-Rs, of which none were brought into the US, are a relatively common "sight."

    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.

    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.

    A "quality full wave rectifier" can be made with four power diodes at less than a dollar each; the PX6007 springs to mind, or the BR106 bridge package if you need really heavy currents.

    To be honest, I'd much rather be using a mercury arc rectifier - semiconductors are for wimps! ;-)

    Switching power supplies don't use full wave rectifiers.

    Indeed they do. The switch is essentially a PWM delivering a chopped DC signal with a mark-space ratio modified by feedback from the output rail. The DC is provided by a bridge rectifier feeding a high voltage capacitor of modest value; by using a half-wave rectifier you need double the capacitance to achieve the same ripple trough, and high voltage capacitors are much more expensive than diodes.

    Here's an example of an ATX PSU: http://www.pavouk.comp.cz/hw/atxps.png The bridge rectifier is at the top left, components D21-24.

    What switchmode PSUs don't use is large stepdown transformers. You can find out more at http://www.smps.us/smpsdesign.html. Google is your friend.
