So I have a 6 GPU rig with Sapphire Nitro 5700 XT and a Corsair AX1200i psu. With 5 cards it runs OK but when I add the 6th card the rig shuts off and restarts once auto tunning hash rate begins. I checked and the AX1200i is a multi railed psu with DSPs which means there is an OCP (Over Current Protection) enabled. Could this be the reason it keeps tripping off; perhaps when auto tunning more power is drawn.
If this is the case, is there a way to switch the psu to single rail or I’m I better off getting another psu?
