GTX 570 SLI On a 850W?

post #1 of 10
Thread Starter 
Hello guys,

This week i'll get my system shipped in from the Philippines and i already purchased a second GTX 570 but im still not sure if my Cooler Master M850 can handle it all

I atleast want enough space for overclocking.
My i7 860 is running on 4ghz 1.3625v and the OC goal for the 570's are 850/1700/2200 + a mild voltage increase.

Total specs:

i7 860 4Ghz
Asus P7P55D-E Deluxe
Corsair Dominator 4x2GB DDR3-1600
2x MSI N570 GTX
1x Spinpoint F1 640GB HDD
1x OCZ Vertex 3 120 (planning for a second)
6x 120mm fans (a few with LED)
4x 30cm's UV Sharkoon cold cathodes
2x DVD/R's
CoolerMaster Real power M850

The CoolerMaster Real Power M850 has 64A (768W) on the 12v rail(s)

Could someone please help me out?

According to Phaedrus, Two SLI 570's =750 watts, + 25 watts for Nehalem i7 processors = 775 watts. You should be fine.

Well, The Cooler Master Real Power M850 isn't the newest PSU but it has about 85%
