(need psu recommendations] Asus GTX 760 Direct CU2 with one 8pin

My friend has recently bought a GTX 760, Direct CU2 and while building his computer, I realised that he only had 1 6 pin on his PSU (he bought one of those unbranded ones).

 

So I was wondering if anyone had any recommendtions, 600-650w

 

specs

AMD 8350, 2x4GB Corsair Vengence, 3 fans total, 1 hard drive.

 

Thanks... cus I know I'll get good recommendations anyway.

Corsairs RM Series are pretty good I've never seen the Fan on it spin EVER. its an 80+ gold PSU and it will power all and any future components.
