Corsair AX850 and GTX 580 SLI - Page 2

post #11 of 16
A good 850W PSU is more than enough to handle 2x 580's with an i7, and still have plenty of room for overclocking.

Test Setup
i7-970

Running 580 sli with 900mhz on core 1.15v along with my 2500k at 4.8ghz 1.4v. Haven't had a hiccup. You're definitely fine.

Been running 2600K @ 5ghz and sli 580s @ 900mhz on ax850 as my daily clocks for 9 months with no problems.

It takes higher OC and benching to actually pull even 850 from the wall with a kill-a-watt... regular gaming is like 650-700 from the wall.

With Corsair AX850 on system:

i7-2600K (4.7GHz@1.36V, w/o HT)
MSI P67A-GD80(B3)
G.Skill F3-16000CL9D-8GBRM
GTX 580 1536MB SLI (880/2200MHz@1.1V)
Asus Xonar Essence STX
Creative X-Fi XtremeGamer Fatal1ty Pro
OCZ Vertex 2 OCZSSD2-2VTXE120G
WD20EARS
LG GH24NS50
Few not powerful fans

I got 715 watts "from the wall" in BattleField 3 @ 1920x1080 on Ultra.

Now I want use this PSU with the same system but with MB "ASUS Maximus IV Extreme-Z" and maximum overclock of CPU and video under water cooling (+50 watts for fans and pump).

Is it OK?

1000W at the wall is, of course, 850W at 85% efficiency.

So my system in the sig (with x760) is, going by numbers here, pulling ~700 from the wall meaning it's only using ~644W from the PSU?

It depends from your PSU efficiency. If it have 85% on that load, so -15% from 700 watts. Yours PSU efficiency: http://www.jonnyguru.com/modules.php?name=NDReviews&file=print&reid=235
