Can I SLI with this setup?

post #1 of 9
Thread Starter 
1x Intel Core i7-3770K
1x ASUS P8Z77-V PRO/THUNDERBOLT
4x Western Digital Scorpio Black WD7500BPKT 750GB
1x Crucial M4 CT128M4SSD1 2.5" 128GB SATA III
1x ASUS Xonar D1
4x COUGAR CF-V12H
1x COUGAR CF-V14H
1x ASUS BW-12B1ST/BLK/G/AS
1x LG GH24NS72
4x Crucial Ballistix Tactical Tracer
1x EVGA 02G-P4-2676-KR which I want maybe to SLI idk yet

The reason I'm asking is I personally don't know. The eXtreme Power Supply Calculator shows that when I add in my overclock of 4800 @ 1.30 Core Volts and my other stuff like using 100% TDP and set capacitor aging to 30% I get a number of 659 watts required.

So I have this now FSP Group AURUM GOLD 750W

I've checked sites and found this info:

"Achieves up to 92% efficiency at 50% load, close to 88% at 750W and mid-80's efficiency up to ~830 watts in my tests. Also does well on low load tests."

Then here in overload tests I see it pulls 836 watts at 82.6% efficiency which matches what the person said on Newegg above.

Here's some more stuff about its voltages etc.

So if this only achieves around 80% efficency at 750 watts that means available watts are really 660 right? And I"m barely at that requirement according to the PSU calculator. So why do they even include SLI as an option on this thing then? Very confusing

It doesn't mean it can only do 660w. Also, the overload tests are done in a hotbox, 112f+. Efficiency always drops at such high temperature. According to the overload tests, the unit would pull 868w = It pulled it's rated 748w just fine. (@ 86.2%)

GTX 670 SLI on that no problem

As long the psu supports multi gpu sli and crossfire you are good to go, and the motherboard ofcourse.
800-850watt would be an ideal psu. I reccomend cougar, bequiet! Or corsair.

Its up to you my friend

All brands has at least one crappy unit even Seasonic and every brand has at least one OEM they buy from take OCZ they have 6

Thats why you name models not brands

Alright, I think I'll consider it then if you think it's ok. It would mean just saving up like 400 before the gtx 670's go away =Z better than buying a new 780 and going broke =|
