I have H110s running 13 Nvidia all same 10 series cards no issue. Have a h110 running 11 570s and 1 560 no issue did have 12 570s but had a psu go bad and new one was short plugs so had to reduce. The 560 is just cause
14mhs is 14mhs. Maybe check bios..mine is H110 Pro BTC P1.10 ...
Im remote until morning i can get more specific info then if needed. (look at actual bios)....but ive got several rigs running 13 cards.....so not sure maybe something to do specific to the newer card?
I will note the rigs have i5-7400 cpus in them,...but i have an old 1050ti rig of 13 that is running a G4400 pentium just fine (50% load on cpu)...if that info helps....wierd.
And i have had 2 h110 show up doa....but they didnt work at all and got exchanged. Yours is working but not when over the #....
