5·
3 days agoSome systems just need a pure sine wave UPS. Especially high grade server hardware. But test the UPS with other computers, it could just be faulty.
PFC is in the power supply. The bios doesn’t control it. Only servers may have this control.
Try running some equipment that needs extra load from the UPS. TV? Gaming system? Again could just be an issue with the UPS.
