I have a 6X 1660 Super rig that I just added the 6th card yesterday. Since then the computer has restarted itself several times. It was running for weeks with 5 cards with no issues, but now that I added the 6th card, I can’t keep it mining consistently.
PSU 1200P2 (measured 760W at the wall) for the whole rig.

Mining with Pheonix Miner under Windows.
Any ideas? Or is there a way to auto start Pheonix Miner on startup? I already have the BIOs set to restart the computer upon power failure. And right now Nicehash is set to auto-start mining on start-up which is how I can tell that the computer restarted. It is running through a Kill-A-Watt. Could that be the issue?
