Computer power supplies won’t be damaged by modified sine wave inverters. Be sure to test your power supply on the UPS when nothing important is running though. Some power supplies will shut down as soon as the UPS switches to battery.
Comment on UPS and servers : simulated sine wave good?

There are some devices which will protest under modified sine wave, and some which may even get damaged. I recently accepted the risk of using an msw inverter with some electronics and did not notice any issues, but I had read that the device would be fine with it.

That’s my thought, that the power blip is basically too long, and why I suggest to OP to try a different UPS.

Seen that dell server PSUs are not really friendly with mdw but when PFC disabled it should not pose problems… But here it does

Well, might have to do some isolation tests if you can borrow a pure sine wave UPS and see if it makes a difference. Outside of that, the power blip might be too much for the power supply to handle or it trips up BIOS/mobo voltage sampling.

Sadly I don’t have a pure sine wave UPS, but if I’d tried it I would replace my riello one. But I think that it would work with the server… Do you think it’s any good to try to find a solution or buy a rsw one?

Ideally you’d isolate the UPS as the problem, so it would be good if you could borrow one for a few days or so to check. It could be that the UPS isn’t the problem.
Consider reviewing the return policy of a company where you can get a pure sine wave inverter and if it fixes the problem you’re good, and you’ve already got your replacement. Else, there may be a configuration or hardware problem.
