post #1 of 21
Thread Starter 
Hey fellas..

Towards the end of this week i will be buy all the components needed for my new build (specifications are in my signature below)

I want to buy a power supply that is capable of running another GTX 280 in the future along with the Single im going to buy now..

i had a corsair 750 in mind as it has 4 PCI-E connectors.. will this stand up to it??

if not.. what do you reccomend?

It's time to go to a 1000w!
You are gonna need power and there's no reason with this setup to not go 1000w.

If you are on a budget, you'd be better off with the Radeon HD 4870. (Unless you already have your motherboard.)

that corsair will be plenty. according to VR-Zone GTS280s in SLI only pull 508w at load, and with a quality company like corsair you should be fine.

750w just doesnt sound like it would be enough for sli gtx280's...Im also not an expert in power requirements lol.

The max power of draw for one GTX280 is around 230w so 2x is 460w, another 200w for OCed Quad and other components so Corsair 750w should be ok for now. Start to save money and look for a bigger PSU.

Do the GX2'S draw as much power as the gtx280?
