Hello, about 4 months ago I had a pc built (2080ti, 2990wx tr, 64gb Corsair memory, msi creation motherboard). The computer was doing great, but randomly started to turn off without warning recently. It happened every other couple days. It would take about 5 min to turn back on after unplugging and no error messages popped up. From what I read it seems like it’s the power supply. I have a thermaltake tough power 1200w 80plus platinum power supply. Is that not powerful enough for my setup, or could it be faulty? It worked fine for about 4 months. They ran diagnostics at frys but can’t find anything. Wanted to know if I should get a new ps and which one would you recommend so I don’t fry all my components. Thank you!
