Hi folks,

While playing a graphics intensive game today (Black Desert Online), both of my two monitors suddenly went black.  The computer stayed on, and I was able to hear the game for a few more seconds before the sound cut out.  I tried restarting the computer, but that didn't work (wouldn't be here otherwise).  The lights turn on, all the fans work, and no system diagnostic amber lights that I could see.  After a few additional restarts, I noticed that my other peripherals (keyboard/mouse) weren't turning on either (no keyboard or mouse lights).  My keyboard is fairly power intensive, and requires 2 USB slots to work.  

After trying various solutions posted online with no success, I eventually disconnected the GPU from the PSU and turned on the computer.  When I did that, the keyboard/mouse began working again.  Another thing I noticed was that, with the GPU plugged into the PSU, if I pushed the power button the computer powered off immediately (which was unusual).  When the GPU was unplugged from the PSU, I had to hold the power button for a few seconds for it to power off (which I consider normal).

Is it fair to say that this is most likely a PSU issue?  I can't think of any other reason why unplugging the GPU would cause the keyboard to work.  If we do think it's a PSU issue, does anyone know if I can get a non-OEM 1000W power unit to fit in the Aurora case?  If so, any suggestions on one?

Thanks in advance, I appreciate you all.
