Hi everyone, I just put together a new computer (my first build) and everything seemed to go really smoothly until about 20 minutes in... The computer just shut itself off. I figured it was a one-time deal so I turned it back on and 20 minutes later the same thing happened (it may not be 20 minutes, but about that long). It's done this every time so far (about 5 times) and so I just went into the BIOS menu to watch the CPU temp, it stayed at 45C+1 the entire time, which as I understand is on the warmer side of average, but nothing that would shut down the computer. I'm using: Intel i7-950 3.06GHz (stock fan) Antec EarthWatts EA650 650W Continuous PSU 2 x G.SKILL Ripjaws Series 4GB 240-Pin DDR3 SDRAM DDR3 1333 EVGA GeForce 9800GT 512MB GPU Gigabyte GA-EX58-UD4P motherboard In an Antec 900 case (plenty of fans, system temp was 35C) Since I don't even have an OS installed (I can't get through the installation before it shuts off) I'm really not sure what to do. Do you think it might be the power supply? I have a 550W OCZ Fatality that I know is working, but I don't know if that's enough power for the computer to test it. Thanks!
