Hey guys, I am going to build a gaming PC for a friend soon and I just want to make sure if I am choosing the right PSU for it.

Here are the specs:

CPU:
Intel Core i5-2500K 3.30GHz

mobo:
Asus P8Z68-V GEN3 Intel Z68
http://www.overclockers.co.uk/showproduct.php?prodid=MB-493-AS

Memory:
Kingston HyperX Genesis Grey 8GB (2x4GB)
http://www.overclockers.co.uk/showproduct.php?prodid=MY-094-KS

HDD:
Samsung SpinPoint F3 500GB SATA-II 16MB Cache

GFX Card:
ATI Radeon HD 6950
OR
ATI Radeon HD 6970

I was thinking about something like 600W for a single 6950 or 6970 should do the job.

Probably he is going to xfire in the future so buying a bit more powerfull PSU now wouldn't be a bad idea.
Do you think a good quality 750W PSU would be enough for 6950+6950 or 6970+6970? Something like:

Get the ATI Radeon HD 6970 (or the gtx equivalent)

For the PSU:

or

If you want to crossfire down the line with another 6950/70, best of getting a 750/850, save the hassle later on (I'd go for 850 anyway, due to less noise and more head room for upgrades in the future, also the price is almost the same in any-case)

Mainly suggesting the XFX due because they are semi-modular, which completely gets rid of cable clutter since only the essential wires are perma attached, while not being as expensive as the corsair equivalent's.

Ones modular, the other isnt, both are Seasonic built, the Modular one is Silver efficiency rated.

Both are fine for single cards or even Crossfire 6950's

Or there is a 850W modular one that is cheaper than the 750w above,
