GTX 480/System: Enough Power?

Danny Bui said:
Well we know that the GTX 480 uses about 10W more than a HD 5970 as shown in this review.

Under OCCT Load, a HD 5970 can use up to 360W of power by itself. So a GTX 480 would use about 370W at OCCT load, give or take a 10W.

A stock Core i5 950 with one drive, mobo, and RAM will use up to 190W at full CPU load. So you're looking at 560W plus a few extra wattage for the DVD burner and fans. So let's call it about 600W even.

So while doable with the 620HX, it's pretty much pushing that PSU to the limit. So yeah, the purchase of that 850HX was most wise.

That's pretty much what I figured after adding it all up as well, so thanks for the feedback and confirming my suspicions regarding this.

I've been saying that I haven't wanted to keep the PSU pushed to close to it's max for too long, so I'd rather have the extra power with 850W just to keep all things covered.

Thanks again for the feedback and confirmation.

Yeah, a 1KW unit would be safer territory for the rig you're describing. I've got a 1.2KW unit that I bought to run 2x 5970. [Quadfire scaling was iffy though! :mad:] Looks like the GTX 480s are nearly as power hungry as the dual gpu 5970s :eek: so I'm glad I have the power to spare!

QFT:)

If peeps can buy 2X GTX480 might as well buy a psu that can handle both cards and more
