View Full Version : SLI Power?

07-26-07, 08:34 PM
Ok, building my new pc and have all the parts except the hard drives and sound card.

My 8800gtx has 2 6 pin power connectors on it.

My 620 watt Corsair power supply (modular) has 2 6 pin power connector cables that I can use.

One end has a 6 pin, and a second 2 pin thing.

My question, and I don't know if I have given enough details. . .

This power supply is supposed to be SLI ready. If it only has 2 6 pin power cords on it (and I know there are adapters), then is it really SLI ready, or am I just all messed up?

The power supply is here.

It's not certified for GTXs in SLI, but they'll run just fine (http://www.legitreviews.com/article/462/1/). You'll have to use a splitter cable though.

If you're going for a 8800 GTX SLI setup, I recommend you step-up to a good PSU capable of 750-800 watts. The PSU you've selected is fine for a single 8800 GTX, but it's pushing stability if you put 2 GTX's on it.

I think it would just about be OK, but I should think you'll be pushing that PSU hard and the fans will spin-up big time.

I was running this system, exept without SLI, on a CoolerMaster 550w and the power meter was reading about 400w in game. I ran it SLI'd on the same PSU and the meter read about 490w, but the fan was far too loud, so I got the one i'm using now.

The GTX's don't use that much power, but I doubt they'd OC as well as they would with a bigger PSU.
