Toughpower GF1 750W Gold POST issue

[ras]

Hello,

I am experiencing a very weird issue. If I play a GPU intensive game (RTX 3070) and then power off the PC normally through windows and try to power on the PC after 5 secs, POST fails with CPU and RAM debug lights lighting back and forth. If I wait 2-5 min, no issues. Now, If I don't do anything that puts a load to the PSU, such as browsing, youtube, etc, and power off the PC and power on right away, no POST issues. None of these issues happen if I just restart Windows, no POST issues at all regardless of what games I was playing. My gut's telling me this is a PSU issue because it's only happening during Power On of the PC. Has anybody seen something like this happening?
