Hello peeps,

I am thinking about buying the following components, the issue is I am not sure which PSU I need.

Components:

Gigabyte X79-UP4
4820K 3.70 IvyBridge-E
Noctua NH-D14-2011
Corsair Venegeance Pro 32GB Quad Channel Kit
Sapphire HD6870 (already have it)
2 x 2TB
1 x 128Gb SSD

In the future when I have the funds I will probably add more hard drives and potentially more RAM

Based on the above specs, I am considering the following PSUs


Seasonic 660w '80 Plus Platinum' Modular Power Supply

Or

Antec High Current Pro 750W Modular '80 Plus Gold' Power Supply

Are the those PSUs powerful enough and if so what would you choose?
 
Thanks,

I checked the specs for the graphics card (still in its box, was a gift from a mate) and it recommends a minimum PSU of 500 watts.) I just wasn't sure with all the other components.
