700-750w enough for this...?

post #1 of 12
Thread Starter 
I'm building up my folding rig, and here's what I'm planning:

Phenom II x6 ~ 3.8-4.2 Ghz
890FX MOBO
GTS 450 - three-five of them
Six 120mm Scythe fans
Four 140mm Scythe fans
Corsair H50
2 fan control panels (Aerocool F6XT & Scythe KM01 "Kaze Master")
1 HDD, 1 SSD, 1 DVD-RW

I THINK that's it, LOL. I'm not looking for a parts critique, just the wattage needed. I was hoping 700-750 would be enough, but I'm not the PSU guru

is it 3 or 5?? i would say a 750 would handle 3-4 maybe i dunno about 5..

Should be fine on a good 750W, yep.

I know it's not in the "recommended PSU FAQ" in this forum, but I am considering this PSU:

COUGAR-SX850 850W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS SILVER Certified Modular Active PFC Power Supply

I like the looks of the Cougar PSU's, and the Newegg Unboxing movie was rather informative. They make a group of 700w PSU's, but it seems the concensus is that may be enough for 3-4 GPU's, but if I get the chance to fold on 5, it wouldn't be enough.

Thanks again

three-four GTS450s would be fine on 750W but 5? that is depending upon the quality of the PSU

I would recommend

Since you're going to be running that kind of load on the unit 24/7 I'd get nothing short of an 80 Plus Gold rated unit... save on your power bill.

Seasonic x-850 or corsair ax 850 perhaps? Nice to have some headroom.
