GTX 480 and my PSU

[Evilclive]

Will a GTX 480 run on this PSU?(already own it btw)

Newegg.com - COOLMAX CL-700B 700W ATX 12V v2.2 Compatible with Core i3/i5/i7 Power Supply

P.S. What about a Ati 5870?

You shouldn't have any problems.

With a GTX 480 or Radeon HD 5870.

i had a 5870 running fine on my 700w psu it was overclocked and so was my cpu , no problemas as long as its a good solid make , that one you linked too isnt bad tbh , 4 12v rails 16a on each , the 480 draws more power but still ok

never heard of the make seems a bit cheap i dont trust it

Edit original answer edited as i didnt check out the psu specs properly

Be worth checking how many amps the 480 needs against how many amps your 12v rail supplies. Not sure what the power requirements off the top of my head are.

 

[Evilclive]

says 42 amps on a single 12v rail, guess mine isnt good enough?

It's fine.

You get 16A on each of three +12V rails, and 12A on the fourth. That's 60A altogther. (It's limited to 570W total at +12V, though, or 47.5A total.)

It has the required PCI-E power connectors (one 6 pin, one 6+2 pin) for a 480. You should be OK. It's not a high-end model, but it doesn't look bad.

I prefer single-rail PSUs, but they can be expensive:

+1 on that 2 at the most for me. As I have always considered the power supply a very important core component in any build. Fabe

PSU Myths Busted - Myth 2: A Single-Rail Power Supply Is More Powerful Than A Multi Rail Power Supply!

SLI and CrossFire Push Power Supplies to the Limit - CPUs, Boards & Components by ExtremeTech

It's not a belief that single-channel PSUs are"more powerful". The above article (from 2006) detailed problems with high-powered graphics drawing too much current from one of the rails.

I hope that this isn't an issue in 2010, but it's difficult to get specifics on how a PSU is wired.
