I have been having a very weird POST issue.

My specs (all components 1 month old):
PSU: ToughPower GF1 750W Gold
Mobo: B550 Aorus Pro (latest bios)
CPU: 3700x Ryzen 7
GPU: RTX 3070 Asus Dual OC
RAM: G.Skill RipJaws V series 16GB 3600 CL16

If I play a GPU intensive game 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 flashing back and forth. The CPU led will clear and then move to DRAM, it stays there for 2 secs and then moves back to the CPU led and back to RAM, and keeps repeating. If instead of Powering On the PC right away after shutoff I wait 2-3 minutes, no issues. Now, If I don't do anything that's intensive, 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 temps when gaming for GPU are 71C and CPU 70C. I can game all day without issues, hell I can run cyberpunk and then run cinebench r20 in the background and I have no issues with the PSU. I would not have found this issue if it was not for an email I forgot to write after a gaming session. I shut off my PC and then remember I had to write an email and turn it on right away and noticed the POST issue. I have been testing to see what triggers it and it seems to be consistent with having a GPU intensive game running for a while before shut off. If I play a GPU intensive game and then quit the game and just browse for half an hour and then shut down the PC and turn it back on, no issues.

This will be pretty hard to hunt down IMO. How about you make it a moot point by just having a blank screen saver at 5 minutes and leave it on more, shutting it off when you won't use it again for the day?

I have several machines that get restarted a maximum of once a month and the monitors turn off at 15 minutes and I've never had any issues.

Yup, I am at lost. I initially thought it was the RAM, so I disabled XMP but the issue still happened. Could it be heat? The GPU is blowing directly into the cmos battery, but I never heard issues related to that.

Yeah, I've not seen that in the 30+ years that I've been building lots of machines, which is why I think that it will be very difficult to figure out -- and I have a dozen machines and boxes of parts. Theoretically, it could be that shutdown immediately after the game turns off the GPU fans and they don't have time to cool it down so require a bit of time to drop back below their thermal limit. But who knows.

Yeah at this point I will just live with it. I even switched off the PSU, and pressed the power switch on the case to discharge the capacitors to see if it works right away but NO, I have to wait regardless after a heavy gaming session lol.

Just an update. Contacted Thermaltake and explained my issue. They told me to RMA the PSU. Very interesting, surprised they decided this just by the description of my issue.
