Is this PSU enough for my build

[IainCheesecake]

Processor: i7 2600k
GPU: Asus 6950 2gb
Ram: Patriot g2 2 x 4gb 1600
Motherboard: asrock p67 pro 3
Optical drive: Asus blu ray combo
HDD: 2 x western digital 500gb caviar blue
PSU: Antec 520 watt high current gamer

Is this psu sufficient to power this build? I will overclock and add a second 6950 later this year, but I'll also upgrade the psu then aswell.

No for the 2gb i would go for 600w.However guru3d states 500w would be the bare minimum at stock clocks.

It is sufficient enough for now but surely not if and when you add another 6950 in there and/or overclock your CPU.. Btw, that board has only one pci express X16 slot I guess..

I know it won't be sufficient for when I overclock and/if I add a second 6950, this psu is just to get me through a year and a bit. So 520 watt psu is just about ok with everything at stock clocks?

With the i7-2600K it will be a matter of days before you will feel the urge to overclock. You will need a PSU with some headroom. Go for this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139012

It is modular and will help in better cable management, resulting in better air flow and lower temps.

Agreed a higher rated psu will better suite that setup especially if you overclock and add another card in future

Even overclocking your cpu to 4ghz, the power supply calculator I used said 408w and recommended a 458w psu.

I added 20% for capacitor aging, 2 120mm fans, and 2 usb devices.

You psu will be fine for a single 6950 2GB at stock speeds and a i7-2600K at 4ghz.

I've gone for a 620 watt antec PSU now anyway, thanks for the help
