Yep, you guessed it another Power Thread...

post #1 of 21
Thread Starter 
Hi,

My question is i am getting an xfx 750w core PSU and im looking into graphics cards.

Im sure i would be able to run two 460's over clocked fine but with two 470's i wouldn't be able to over clock them.

Is it worth paying extra for the 470's and would they run ok?

( i have 2 HDD's and will over clock my 930 to about 4ghz)

This should really have gone in the Power Supplies forum, but yeah even two GTX 470s would definitely work without a problem.

I still think you need at least 850 watts to give a little more head room cuz you're overclocked. IMO.

A 750 should be more than enough for your needs.

But a quality 750W like his can easily run a typical system with two GTX 470s in it, even when overclocking.

A single GTX 470 at stock can pull a maximum of 215W. A 2nd one wouldn't be able to pull all 215W due to scaling. But I don't know how much less so I'll call it 200. So if I'm right (which I'm probably not), then that would be 415W total, but probably less because of scaling. The 750W XFX Core has a claimed +12V wattage capacity of 744W, so this would leave 329W for the rest of the system on the +12V. That's a ton of power left over which leaves plenty of room for overclocking everything, and I'm probably guessing on the high side for the power draw of two GTX 470s in SLI.
