View Full Version : PSU for 8800gt SLI

06-28-08, 09:12 PM
I'm wanting to get another 8800gt for SLI and I have a Silverstone Zeus 560W with 38A on a single rail. My setup is:

Core 2 Duo E6400 @ 3.2Ghz
2 x Evga 8800gt vanilla
4 GB Corsair DDR2 800
2 Hard Disks
2 Optical Drives
3 Case fans

I know nvidia recommends only 450W for SLI but I kinda wanted to see if there were others with similar setup running gt's with no problems. Even with mild overclocking on the CPU and GPU's. Thanks for the replies.

I suggest getting the Hiper 880W Type M (http://www.newegg.com/Product/Product.aspx?Item=N82E16817128010) that I have.

I'd go with a supplementary psu like this one:

Thermaltake Power Express (http://www.eurowide-pc.co.uk/thermaltake-w0099rb-250w-power-express-retail-p-28089.html)

That's not enough to power both cards. The 8800GT has a power consumption of 138W.

He's already running one card on his current PSU, so the additional PSU would power just the additional VGA card. They do a 450W one as well if you like.

I say try it...GO SLI...If you current PSU doesn't hold up you can always make another trip to the store. I have found my self wasting money thinking to far ahead. Just try what you have, and then upgrade later.

You shouldn't have any problems with the C2D, but if you go Quad...you will need a bigger PSU.

I had a C2D, SLI 8800GTs and a Ultra 500w. Until I got the Quad Core, and started overclocking I didnt notice any stablity issues.
