hi i have an fx 8320 and i want to overclock it but im going to get an r9 280x and was thinking of getting another one in the future and cf them so i want to know how much watts does my psu need to have so that i can overclock my procesor and run the 2 r9 280x in cf

Your CPU is going to bottleneck two 280Xs. You'd want to switch CPU before then.

 

850W would be the best option to run that system.

850W.

 

 

Get EVGA SuperNova G2/GS series PSU.

I'd recommend maybe a 850W Supply . I think 750w would do but i'd recommend 850w for a bit of security/headroom too.

 

Get a G2 Supernova, i have one and it does the job beautifully.

for 8300 CPU + 2x 280X I'd say 800-850W. if it were an intel CPU, then 700W would be enough but yeah.

Aside from mentioning bottlenecks you should go for 750 to 850W

thanks for the answer i got the 8320 really cheap and it was still in the box not open i read on some forums after i got my cpu that its not a problem to run 2 280x but i guess 1 will do just fine just 1 last thing will an FSP Raider 650w do for this a single 280x and overclocked 8320?

It's a bit overkill. A decent 550w is already more than enough.
