Corsair GS700 to SLI GTX460?

post #1 of 14
Thread Starter 
Hello guys, Long time lurker here and im very thankful for all of the great information Ive been able to gather so far. The question I have goes as follows:

Currently My rig consists of a i7 960(stock),An x58UD3R Gigabyte MOBO, 12GB of 1600mhz ram, a evga gtx460 "factory super clocked" and a Corsair GS700 PSU. Now that skyrim is coming out, Im thinking about adding an additional gtx 460 of the same make and model to my set up in a SLI configuration. Will I need to purchase a higher wattage PSU or will the GS700 I have now be fine? I dont plan to OC in the near future either. any insight into this would be greatly appreciated. Thanks!

I think you will be just fine with that. However if you wanted to overclock the CPU/GPU and have a nice bit of headroom, get the HX750 from Corsair. Yes the price is increased due to the modular design and the efficiency rating but it's well worth it.

What?

He'd be fine with a half decent 550w and be able to overclock those 460s and his cpu pretty decently.

OP, the Corsair GS700 is more than enough power and you've got plenty room to OC.

Mine is working just fine with antec 650.

Half decent 550w? I have to disagree with that. Overclocked components need much more power.

And water is wet.. that doesn't chance the fact that a half decent 550w unit will run it's SLI setup without an issue.

@ OP, you'll be more than fine with your current PSU.

"BTW we stress the GPUs here,. not the processor, so you need to add another 100~150W for overall power consumption."

433W+100W=533W
433W+150W=583W

Also please note that the video cards were not overclocked during the test.

That's power at the wall, you do know that power supplies are rated at output not input, as so after you factor in efficiency you'll be well below 400W, with an overclocked rig without any power saving features while running benchmarks.. and that's the peak value
Chances are he'll never see 500W draw in anything except stress tests and unless he's a bencher a solid 500W unit will easily do the trick for him

you'll be more than safe

I'm running 2x GTX 580's on a 750w for months now, with no hiccups
Shhh!
