I just built a new computer and put everything together fine but after a few hours of casual gaming the GPU sparked and I smelled burnt plastic. The PSU is a seasonic 750 watt and the GPU is a Radeon rx 6700 with an MSI b450 tomahawk motherboard. I used the cables that came with the power supply so I don’t think a brand new seasonic would be the issue. Any ideas on what could’ve caused it and where to go from here?
