Is a 750W PSU enough?

I'm looking to get the following system:

CPU: AMD 8350
GPU: MSI GTX 670 PE (Already ordered, found a great deal)
Motherboard: Asus M5A99FX PRO R2.0 Motherboard
Case: BitFenix Shinobi (Window Edition)
Memory: Crucial BLS2CP4G3D1609DS1S00CEU (2x4GB)
PSU: Corsair Builder Series CXM 750W Modular 80 PLUS Bronze
Hard Drive: Western Digital 1TB
Heat Sink: Cooler Master Hyper 212 EVO

I know that a 750W PSU is enough for the system above but if I was to get an additional GTX 670 in the future to run in SLI, would a 750W still be enough. I am also planning to overclock the 8350 to around 4.7GHz.

Thanks for any help in advance.

AMD 8350 - 220W
NVIDIA GTX670 2SLI -340W (each 170w)
220W+340W=560W

YOUR PUSH 12V HAS 744W

that is enough :D

Since the 8350 already sucks a lot of watts, i'd go for a 850 to be safe since you want to OC your CPU.

For a system using two reference clocked GeForce GTX 670 graphics cards in 2-way SLI mode NVIDIA specifies a minimum of a 700 Watt or greater power supply that has a maximum combined +12 Volt continuous current rating of 45 Amps or greater and that has at least four 6-pin PCI Express supplementary power connectors. A 850w will be more than enough, but again, since the 8350 already uses 220w, and you want to OC it, then you should go for a 850 just to be safe.

NO


gtx670 2 sli the max will be at 444w
amd fx-8350 overclock TO 5GHZ the max will be about 300w

444w+300w=744w

so that is enough

Sounds good I guess I'll stick with the 750W for now if I need more in the future I can always upgrade! Thanks for the help =)
