Question Pc suddenly shuts off without warning

[Benjamin Haukaas]

So my friend has a pc, that seems to suddenly just shut down without warning. He has a ryzen 5600x and a rtx 3080 with a 750w Corsair PSU. all temps look fine and everything seems alright until the problem occurs. one detail is that the pc wont turn on again until he switches the psu off and on again.

What is the PSU age and specs (model no)?

Well, the RTX 3080 needs a minimum of 700W PSU, while the RM750 is just barely enough. If the system shuts down only under load, I think that the problem is caused by the PSU. If possible, can you test with a different PSU under load?
