Hi
I bought a new hd 7990 and psu kentek 850w
but unfortunately the psu kentek its bad it can run the hd 7990 but with low gpu usage low fps and when i disable the CF some games works better or same as CF, my cpu is fine core i5 2320 and during gaming the CPU usage never reach 100% always on 70 to 85 in BF3 and crysis 3
so I want to buy a new PSU HX 850W , so i need your help
 
Solution
The Corsair HX 850W will be more than adequate -- it is a high quality PSU unlike the Kentek. (I've seen a number of horror stories with that Kentech brand.)
