hi.
it's always the same card that are faulty ?
try switch cards on mb and check if it's the same card ... or the same slot-card who is faulty ?
I git this kibd of trouble, it was a weakness on my psu.
what is your PSU ? does the 12v is mono or multi-rail ?
if multi-rail, be sure that is not overloaded even if the total power of the PSU is not reached.

Nop, a lot of card can be faulty
I already switch card in different pci slot of the mb and there isn't one "faulty" card or slot pci
I think it's multi, so you think that my psu is "overloaded" ?
for my rig, that was the case ...
my 1600W PSU is splitted.

so 30A = 360W MAX.
but the rail is for 2 gpu connectors.
so 2 gpu at 200W overloaded it ...
