I keep getting this error message randomly when mining on a couple of rigs:

at which point the card crashes and sometimes even the rig crashes.
I get this mostly on a 4 card 1080 Ti rig and a 4 card 1070 rig.
It mostly happens if I OC just a tiny bit (+20-40 Mhz) and if I set the power target close to 100% instead of the usual ~70%.
I'm suspecting it has to be the PSU but it doesn't make sense since they are EVGA SuperNOVA 1300W G2 in both rigs. And I have a rig with 6 x 1070 with the same PSU without any issues. I tried switching around the risers but didn't help.
