I just unpacked and installed a 2080 ti and I'm encountering a problem I had with a 1080 ti I got a while ago but refunded for the issue I was having. The computer starts up normal and works fine. I could run less intensive games, but would black screen and instantly reboot after trying a more intensive things. I tested this with Unigine's Superposition benchmarker, and could run all the tests up to 1080p extreme, which would black screen and reboot as soon as the benchmark started. I want to deny that it is the GPU's fault, but the fact this has happened twice in a row makes me want to hope I won't need to refund this one.
