Does my PSU (Corsair RM850i) have "active PFC UPS?"

Hello,

I have a Corsair RM850i. Does this have an "active PFC UPS?" I have no idea what that is, but it was recommended.

Thanks.

No. A UPS is separate from a power supply. A UPS is a device you plug into the wall which you can then power your PC with if there is a Power Outage or something like that.

But Active PFC can be a PSU thing...

I know the original RM PSUs had active PFC and since the RMi series are built a little better, I would presume it also has it?

All modern PSU's have active PFC to ensure it is capable of supplying the full labeled wattage on the unit.

A UPS is a separate unit as said that provides a battery backup if there is a power loss. Where they cross is the active PFC and UPS's can sometimes have issues with compatibility.
