So irecently upgraded my cpu from an a10 6800k to a fx 8350 and bought an h80i to cool it and when i went to install everything i did a fresh install of windows and everything seemed fine. I install the drivers for my 280x and the screen goes black so i figure its drivers and try multiple different drivers on multipole fresh windows installs. I later talk to some people and do some research and aperently my power supply isnt big enough. I was wondering if a 750w would bne enough or do i need to go to 800-850 (Current is 600w)

Your current PSU already has enough wattage. Or should, anyway. What's the model? It might be some piece of crap not actually delivering the 600W.

do you plan on overclocking? and i wouldn't replace that psu for not having enough power, but because it's just a crappy psu

if you are planning on overclocking both the video card and cpu, a decent 600-650 watt psu will work just fine, if you want to add a video card and overclock it as will, it might be pushing it with a 600, maybe not with a 650

if you don't plan on overclocking at all or adding another 280x, a decent 500 watt psu will easily power your setup

Ok thanks for the help. I guess i should also ask if the psu could be the problem for something like the black screen after the drivers ive heard alot of people say they have that problem im just curious as to how the psu could cause that

black screen with automatic reboot right?

it could be that you psu just doesn't have enough power or provided clean enough power to keep you cpu/motherboard stable

it's hard for me to pin down with out access to the system itself, but seeing that it's not a great psu, with power hungry parts, i'm going to bet it's the psu, it could also be a problem with your ram, that can very rarely cause black screen reboots, instead of blue screens, but that's pretty damn rare

another thing could also be your computer sharing a circuit/breaker with something that is also power hungry, and causing fluctuations in the current available, this is also rare for new home with breakers, most don't have shotty wiring, you'd mostly see that in older(pre1980, back in the aluminum wiring days or fuses) homes on the edge of small towns

You should be getting plenty of power even from that not ideal PSU. If you can still return it, you probably should and pick up one of the options below. The most ideal being the Antec or XFX units.
