my friend using a
CPU: AMD FX-8150
MOB: GIGABYTE GA-970A-UD3
GPU: GIGABYTE GV-R687OC-1GD
RAM: AMD DDR3-1600 4GB*4
HDD: 1TB WD GREEN
PSU: GIGABYTE 650W

FAN: CM V6GT
CAS: HAF-922
ROM: SONY DVD16x

I was wondering that hes PSU is not enough to supply his components thats why sometime getting lag and bluescreens..

we already tried reformat/software update/bios update/change hardwares such videocards/rams but still getting the same problems.

the GPU consume 500w and the CPU consume 125w therfore the rest 25W going to supply MOTHERBOARD/RAM/HDDS/FANS??

I'm also using a same specs like my friend and with a more 3TB WD HDD and I used a 950W PSU, everything getting well and dosn't have any problem like that.

do you guys think is the PSU problem? so my friend can manage to buy a new one higher PSU..
