I built my first pc today and once i hit the power button everything worked fine and went several hours playing around on the pc after updating to latest drivers and whatnot. Then the monitor screen would occasionally turn black and stay that way for around 1 second and everything would go back to normal. And then around 3 hours of using the computer it just died instantly so i tried to turn it back on and nothing happened. So i wait several minutes and play around with the connections and unplug the psu and plug it back in and it shuts off within 4-5 minutes of use. So im thing its the cheap psu i have my system specs are

cpu-AMD FX-6300
mobo- asus m5a97 le r2.0
gpu-xfx hd 6670
ram- 2x4gb team vulcan ddr3-2133
psu-logisys ps550e12bk atx12v
