My computer suddenly started to power off after about two hours of mining. Start back up it works ok for a couple hours then same thing.
I've dialed back the core to zero and memory is at -400. TDP is at 60 on one card 80 on the other. Temps are fine. Ccminer mining zcoin.
Power supply or motherboard most likely? Seasonic platinum 850w. Motherboard is a msi tomahawk b350. The two 1080ti are not in sli.
do u have wattmeter? 2 1080tis with such TDP will use about 400-500W max. +100-150W motherboard+CPU. Power supply looks nice too, but to test - remove 1 card and start mining without another changes.
