2 Bad RMA's

[blackice1692]

ive RMA'd 2 graphics cards and im about to do it to a third ... before i send it back im thinking maybe my power supply could be killing the cards but im not sure , the first replacment rma died in a week , then the second one i just received artifacts terribly.
ive run stress tests and benchmarks without a gpu and my pc has no issues , i also used my dads GTX 1060 3GB DUAL for a month with no issues at all while i waited for my first rma. i'm just looking for some advice as im finding this whole situation bizarre. I have also been approved for an rma again and received a shipping label.

The CXM is not the best PSU but not bad, should not be causing issues. You may have just gotten bad cards back from the vendor, they don't usually use new cards so anything they have used they may have fixed but poorly.

Yeah that’s what I was thinking , I’ve run stress tests without the gpu and have had no issues at all. Gigabyte says they’ve tested the cards before they’ve been sent but I’m guessing that’s not true ... apparently the rep told me they are going to do extra testing before they send he next one too me
