And so if the option UEFI Deep Sleep is disabled = PC does not start, there is not even a beep signal. A UEFI reset is required to run(sometimes it needs to be done several times)
if S4-S5 is on + option Restore on AC/Power Loss power OFF = as in the first case.
if S4-S5 is on + option Restore on AC/Power Loss power ON = The PC starts up and runs without problems, but if you turn it off for a long time, it will not start up again.

power supply is old(corsair cmpsu-620hx 620w), but still works without problems (in other motherboards)

I will add. in the first variant, if the value AC/Power Loss power ON = PC is not turned off, instead of a reboot.

I also want to say that I checked the power supply, closed the green for 24 pins and it started without any problems. I also checked all the voltages - they are normal.
