Can a PSU Handle 2 GPUs?

[muradw2]

I have a PSU with 620W, can it run 2 GPUs? One with minimum 500W and other with 400W?
If not, can I add another PSU to the same desktop?

please list the exact model of power supply and the 2 graphics cards that you are trying to run. And remember that recommended psu's for gfx cards are rated in Continuous Watts. Many power supply manufacturers rate their PSU's in PEAK or MAXIMUM watts, which is completely useless.

PSU: Antec High Current Gamer 620W Active PFC 13.5cm PSU HCG-620
GPUs: GIGABYTE - nVidia GTX570 OC 1280MB GDDR5 DX11 2xDVI Mini HDMI PCI-E

Why would you pair those two cards together?

For better performance!

I have the same PSU. I found a review of it where they tested it up to 748W before it switched of to prevent damage.

How will that lead to better performance?

PSU should be ok btw.

Why won't it? instead of just 1GB it'll become 2.2GB, right?

Should I get 1000W?

Not even close. You can't SLI those cards together, and the GT430 is to slow to be of much help for a physX card. You're better off just using the GTX570.

No, they are crap.

You probably need at least a 1600kW PSU.

I take it you mean 1.6kW.
