Question PC Blackscreening kernel-power error

[Krissusp]

Ever since I switched my GPU and PSU from gtx 1060 to rx 5700xt and corsair vs650 to fractal design ion+ 660W platinum I've been having random blackscreens. During the blackscreen everything is unresponsive (no cursor, no sound, pc still on, keyboard still on, no caps lock etc.) and I have to press the reset switch for the PC to restart. Sometimes even the reset switch doesn't work and then I have to switch my PC off from the power supply. Temps are ok- GPU doesn't go above 70C and CPU doesnt go above 50-55C. Nothing is overclocked and yes, the GPU is connected to the psu with both 6+8pin cables running from different ports of the PSU. Also in event viewer, there's a kernel-power critical error:
