PSU for 7970+i5-2500K?

I'm currently planning on getting a Corsair Enthusiast Series 850W (aka TX850 V2) for my (to-be) computer. Is that PSU enough for these components, or is it too much? I'm trying to save money here...
Motherboard: GIGABYTE GA-Z68XP-UD4
CPU Cooler: CoolerMaster Hyper 612 PWM (just listing it in case it, for some reason, draws extra power)
Drive 1: OCz Vertex 3 60GB SSD (same reason as above)
Drive 2: WD Green 1TB (ditto)
GPU: Diamond AMD Radeon 7970 3GB
CPU: Intel Core i5-2500K
RAM: G.SKILL Ripjaws X 1600Mhz (2x4GB)
Optical Drive: Pioneer DVR-219L DVDRW OEM (just listing it in case)
And on another note, said components should fit into a CoolerMaster HAF922 case, shouldn't they? It's a pretty big case.

  1. Looks like a nice build and yeah the HAF922 is a big case.= no worries!
    Amd makes efficient gpus the 7970 can run on a 550W psu.
    If you don't ever plan to crossfire here's a couple of good units.

    Once I get enough money/the 7970 gets dated I might grab another one and Crossfire it, but since AMD invented some amazing new technology to decrease the second GPUs power usage, 2 7970s should work with a 750W PSU, right?
    I might also do a little bit of OCing on the 2500K, btw.

    @amuffin
    I'm in Australia and (unfortunately) newegg doesn't ship internationally any more (although if they did I could probably end up buying a second 7970 with the savings)...

    Yep! you're correct a quality 750W will be fine, even with oc's.
