Gigabyte N680SLI-DQ6 - A Mother Of A Motherboard
MojoKid writes "Motherboards manufacturers seem to get more exotic in their designs, with each new chipset release. HotHardware has an evaluation posted looking at the Gigabyte GA-N680SLI-DQ6; a product that seemingly out does every other current desktop motherboard in a number of key areas. The board features four Gigabit LAN controllers, 10 SATA ports, a 12-phase power array, 100% solid-state capacitors, and a unique wrap-around, passive, cooling apparatus that cools both the top and underside of the chipset and CPU socket area. And because the board is based on NVIDIA's nForce 680i SLI chipset, it also has three full-length PCI Express x16 slots for multi-GPU support. It's a good overclocker and performed well throughout the benchmarks."
...does it go to Eleven?

I recognize most of that stuff, but what is a 12-phase power array?
Is this really neccesary?

Yes it's an anecdote! Were you expecting original research in a Slashdot comment?
I intend to launch a tech review site immediately after you give me a copy of that motherboard for review. Just ship it to my house, and I promise you a good review. Mind you I can't really test the board's SLI features unless I have two top-end video cards as well. And I can't really test the overclocking unless you give me a processor, but in the end, you'll get a glowing review. It will be worth it.

Will it blend?

That is the question
From TFA:
Why stick so many ports (4x LAN, 10x SATA) on the motherboard? Is there a performance benefit to putting those ports there, instead of providing lots of PCI slots so you can create your own optimal mix of ports?
The correct term is 'solid-core', not 'solid-state', FYI.
The opposite of "solid-state" capacitors is in this case the aluminium electrolytic capacitors. Presumably they just use tantalum or some other kind instead on this board. Now, these are also polarized and technically also "electrolytic" (besides, they can still fail) but their failure mode does not include emitting nasty goop onto the board.

All the hardware faults I've had in the past few years are due to bad caps. I hope other manufacturers take the hint and ditch using electrolytics for their mobos. The only place I want to see electrolytics are in the power supply.
That's a mother of a product name too.

With 4 Gigabit ports and 10 sata slots this could make a nice cost-effective iSCSI SAN...
rather than any genuine advantage).
No need to turn this in to a Microsoft flame war! ^.^
Good bye, sweet Karma....

Plz. ignore that nutcase below that refers to Wikipedia on 3-phase power, that's about something totally different. I suspect many /.'ers will have some understanding of electronics, but maybe less detailed than I assume. So I'll give it a go in layman's terms:
What you're looking at is a DC step-down switching regulator circuit (look that up if you want). On most mobo's, it converts 12V to around 1,5V, at many, many Amperes (fist rule: power = voltage x amps).
In it's most basic form, it consists of a coil, a (fast) switch, and a diode. The coil(s) are the thick copperwire/ceramic thingies on the board. As a switch, electronic versions known as power MOSFETs (usually black, square plastic thingies) are used. Because diodes have a small, but significant voltage drop when current passes through, this would give unacceptable losses (heat) at the high currents we have here. Therefore, another power MOSFET is used to replace the diode.
Such a pair of MOSFETs is switched on and off quickly (10s or 100s thousands of times a second), with 1 in conducting (low resistance), and 1 in non-conducting (high resistance) state at any given moment. BUT: when switching over, there is some overlap, where both are somewhat conducting, causing a momentary 'short circuit' (=losses, waste heat). Enter 3-state: switch one off, wait very short to make sure the MOSFET goes fully into non-conducting state, and only THEN switch on the other MOSFET.
My guess is this 'Quad-Triple Phase power' is a similar construction, but then 4 times, working in parallel (for more current), or alternating (to lengthen cooling periods between on-states). Basically: a high-current, energy-efficient 12V-to-CPU-voltage converter.
Cool! It's really getting hard to find the old vacuum tube caps I'm using now.
Yeah, Yeah, Yeah, I read the article. Seems to me that electrolytic is kind of solid state, but I get the idea. Whatever happened to mica?
What?
Overheard at Gigabyte HQ...
Regular aluminum electrolytic capacitors are filled with liquid. When driven hard and hot, that liquid evaporates or boils. There are various other types of caps that have no liquid, including solid tantalum and ceramic. They generally have lower ESR (good), and last (for all intents and purposes) forever, but are definitely more expensive.
About the only advantage of an aluminum electrolytic is that it's cheap.
