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? :P 


Looking at my signature are we now? Well too bad there's nothing here...

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.
