I think the problem is the PSU of the server (and I think this normal, not a fault of it), will check further

Only one and it’s a 750 w one. The UPS has a capacity of 900w

The load of the UPS is at its lowest even at boot

So it wouldn’t work with my PC?

Sorry I was talking about disabling the PFC with the dell Idrac, not the bios.

Going to try some heavy load on it.

I only have a desktop computer but its supply is rated 80+ gold, so it has PFC (if I understand correctly)? Maybe I can disable it in the BIOS? (Going to try)

Already tried running different equipment on the UPS such as modem/router from my ISP or a simple home phone. None of them were having troubles with the UPS…

I’ve modified my post, read it again see if you have a potential answer

Don’t want to bother you but it’s directly related to your post, SoulSeek is the network that is used by slskd. It’s a peer to peer network mainly for music the problem is that the network is proprietary

Soulseek is a great network but this shit is proprietary
