I recently purchased a Corsair 850W ATX power supply. Installed it with my Asus M4A89TD PRO/USB3 Mobo. Installed everything and turned on power. Worked for about 20 minutes before suddenly shutting down. Tried to reboot and fans, cpu light powered on for 1/2 second and then turned off though mobo power pilot light stayed on.
Removed all connections and tried the paperclip trick. Same happened to PSU, turned on for 1/2 second then OFF.
Reconnected everything and I let it sit for about an hour at which time everything came back on and worked for about 2 minutes before shutting down.
Any thoughts? Im assuming this is a PSU failure but im hoping it wasnt caused by me. Im pretty confident in all plug connections to my mobo/VGA/drives. Could also be a mobo issue? Could htis have anything to do with my SATA drives?
Also, while building I came to a question: My VGA card has 2 power connectors each with 6 pins. My power supply had two cables with 6 pins with an expandable 2 pins. I assumed i was to plug in just the 6 pin plugs and leave the 2 pin expandable plugs disconnected.
