Problem has resurfaced with the warm weather….
opened the case and blasting a large fan into the case, which is lowering chipset temp to 60c, and all temps look good, but issue persists.
downgraded bios to 1402 and same issues.
any ideas?
really annoyed as my supplier was messing me about and just found out the board is now out of warranty.

Transpires that the Corsair AX1200i PSU has died, and it’s a common issue.
Pending RMA, although it’s a 5yr old PSU but they have a 10 year warranty. Waiting to hear back.

Hello, @kraven72
Based on your previous description, it is somewhat difficult to identify the current issue.
May I ask if the sudden shutdown issue occurred after any changes were made? For example, updating the BIOS or connecting an external device
Is it occurring specifically when running certain programs or games?
Considering your description (increased frequency of occurrence with rising temperatures), is it possible that the issue is related to overheating?
We recommend checking the connections of your relevant devices, using the latest version of the BIOS, clearing the CMOS to restore the BIOS settings, and observing if the issue persists under default settings.
Thank you.

Ok, rewinding a little.
The issue was that the PC would randomly power off and when pressing the power button the PC would go into a boot loop with "Memory Code 00" displayed on the OLED display. Even when this happened the motherboard LED's would light up correctly and the OLED display would work.
Powering off for 30+ minutes would then allow the PC motherboard to boot.
Disconnecting everything left 3 options :
Going through each in turn :
Anyway, eventually the board would not power on for hours in that it would power on for half a second and then power off, so I took the whole thing apart and happened to re-test the PSU with the Self-Test and eventually it showed a problem even though it didn't before. It would seem that when the PSU was cold, the Self test would pass, when it was hot it would fail.
Now armed with the new information, I did an investigation online, and it seems these PSU's are known to do this with dry joints on capacitors within the PSU which when warm/hot, cause problems. Even though these PSU's have a Zero-RPM fan mode, I would not recommend anyone using it.
As for the boot-loop as per the video, i had the motherboard set to Power On when connected to power in case of power cuts when i'm away, this was why it would constantly try to boot instead of trying once and then stopping. Even so, the fact that it tried to power on and the PSU Self Test was Green is what stopped me raising a ticket on the PSU.
Replacing the PSU and everything is much much better.
The only thing i'm not happy about is that Corsair refused to replace my AX1200i with a comparable PSU, and would only give me an HX1500i. That's not to say the HX is not good, but at the time, I bought the most expensive AX PSU on the market, and now i've been dropped a tier.
