I just got an MSI 3070 Ventus 3x oc and it died after just like 4 hours with no oc gaming/watching YouTube. It randomly shut off my whole computer but it did have good temps. I tried it in 2 different builds with 2 different power supplies and its still not working, one a 650 watt EVGA G1+ and the other a Corsair CX650. One board/cpu was a Gigabyte Z390 Gaming X with a 9700k which was where the 3070 was originally in, and the other an MSI Z370 A Pro with a 9600k. I tested both with my 1060 6gb and it worked fine. Looks like I just have some bad luck right? Also if anyone has info on the MSI RMA process, let me know because I may have to go through it.
