Question on Quad Rails

post #1 of 6
Thread Starter 
The PSU I'm looking to buy has (4) +12V rails, here's the link to the PSU: http://www.newegg.com/Product/Produc...82E16817163109
Can somebody please clarify what this means, I know it means more stable power, but will it keep up with 2 nVidia 7800GTX's, and overclocked mobo, cpu, and memory?
Thanks for the help!

The circuitry is seperated providing 4 independant 12v plugs.
This basically means that if you have one rail with 6 hard drives on it and some fans. It will not affect the output of the other three rails. Also for power hungry video cards giving them their own rail each would allow them to take more stable current at full load.

you probably won't need quad rails unless you are running a dual cpu setup or the new dfi expert board that ueses the 8pin 12v atx plug instead of the 4pin.

it is not so easy to always tell which outputs/plugs are on which rail. a dual rail psu will typically have the cpu and gfx card/s on one rail and everything else on another rail. when there are 3 rails typically the first two are for the cpu/s (often the second rail is for the 2nd cpu and if you don't have 2 processors the rail may go to waste)

quad rails are unnecessary. it may help some with stability, but you really aren't going to see a difference between a quality dual rail psu and a quad.

if you want a silverstone, the zeus is a bit more powerful and more tested.

I would highly suggest the Seasonic S12-600. it is just as powerful as the psu you were looking at, it's more efficient and quieter.

This is also a very good psu that I have heard nothing but good about. it also has quad rails, sleeved cables and high efficiency, low noise

I'm getting the dfi expert. Which would be better though? The FSP Group FX600-GLN or the SILVERSTONE ZEUS SST-ST65ZF?
The FSP Group is cheaper, and supposedly quieter and more efficient with 4 x 15 (amps on +12V rails, total of 60). (600 watt, $139.00)
But, the Zeus has 13, 18, 16, and 8 (amps on +12V rails, total of 53). (650 watt, $169.99)

Yes the zeus will work great. It was recomened to me for my DFI, I researched it alot and I may still get it, a little pricey, but well worth the cash in my eyes.
