Help troubleshooting a couple issues

[Ring__]

Hi I've been plague by a couple issues the last few weeks. The main issue is that when I would be gaming with various levels of heavy load gaming such as expedition 33 and schedule one my computer would completely power off with the error code kernel power. My system right now runs a rm650 watt power supply, with ryzen 5 5600x CPU, and ddr4 32 GB ram with an rtx 2060 6 GB vram. I assumed that it was the psu causing the issue so I ordered a rm750e PSU and plugged everything in and the system powers on in terms of the fans spinning but both my monitor displays show no signal and nothing loads. Any idea what the issue could be or if I'm missing something crucial? When I plugged the old PSU back in with the old cords the computer powered on normally but had the same issues with the random shit downs while gaming.

Don't think the PSU is the issue, rather the GPU or RAM

Maybe you misplugged some cables with the new one, no reason it won't work else

Is there a way I can test if it's the ram or GPU cause when I use the old PSU the computer recognizes the ram and gpu. I'm very close to taking it to a local computer repair shop because I've tried everything I can think of

What happens with the new PSU ?

No power at all, no post no picture ?

In the first case it may be doa but in the second I'd suspect a cable issue,  did you use the ones coming with the new PSU ?
