What power supply for i7 2600k high end system

[jdiaz7]

I am building a new system the componentrs are as follows

Case Ultra M995
CPU i7 2600K
Memory- CORSAIR Vengeance 16GB (4 x 4GB) 240-Pin DDR3
Hard Drives- Intel SSD 120 gig
WD 2 Terabyte Caviar Black
CPU Cooler CORSAIR H80 (CWCH80) High Performance Liquid CPU Cooler
GPU-XFX HD-697A-CNDC Radeon HD 6970 2GB 256-bit GDDR5

At this point I am not sure if I should go with a Corsair TX 850 or if the system would require more power. I do plan on overclocking the system not to an extreme. I would appreciate any advise or assistance

850 w is definately enough

For a single Radeon HD 6970 graphics card system a power supply with a minimum of 600 Watts with a +12 Volt continuous current rating of 42 Amps or greater and with at least one 6-pin and one 8-pin PCI Express supplementary power connectors is recommended.

Your choice of the Corsair Enthusiast Series TX850 V2 (CMPSU-850TXV2) with its +12 Volt continuous current rating of 70 Amps and with four 6+2 pin PCI Express supplementary power connectors is enough to run two Radeon HD 6970 graphics cards in 2-way CrossFireX if you plan to do so in the future.

Thank you very much I purchased the power supply before I realized what GPU I was going to use and I thought that perhaps it was not enough. Thank you
