Hi tomerturbo,

May I have the bios version?
Have you changed to the new power supply you used but it was still auto shut down, auto reboot or no boot?
Are the three power supply all antec 1300w?
Thank you.

1. the OCP for the power supply might be too aggressive for some reason - you probably have kernel 41 in event viewer and so on
2. might try an older bios version - these kind of restarts or infinite loops had them with Z590, 10th and 2x16 DDR4 and have them on Z490 as well with new bios versions, and reverting to an older bios everything is rock stable again

try use and older bios and see if it's doing the same

put bios 1003 on a FAT formatted bios pen drive, make sure it is named M12H.CAP
plug it in the USB nearby the HDMI port
turn off your computer, but make sure it is powered
press the bios button few seconds until a blue light is flashing, wait few minutes until bios is updated, start you computer, let it finish the bios update and config your stuff again

Hi tomerturbo,

It might because of EC protection, so when you changed to new power supply, the EC reset procedure was not finished.
Did it occur often?
Is the pc working fine now?
Thank you.

Hi tomerturbo,

It would be take some time to finish EC reset process.
That might be a reason why you changed the new power supply but not worked.
Thank you.
