Corsair RM850x White 850W PSU 80+ Gold Modular and Corsair RM850x 850W PSU 80+ Gold Fully Modular

Those are the same PSU, only in different colors.

 

Power Factor doesn't have a very large effect on residential use, but any 80+ rating requires at least 0.9 (1.0 is perfect), if it matters to you.

 

P.S. I think wherever you're reading from has the information lines garbled...

I searched online without success to finding what the difference is between Active PFC and 70.8A PFC..

I want to purchase a new PSU and I'm debating between 2 similar ones which has different PFCs .. (Corsair RM850x White 850W PSU 80+ Gold Modular and Corsair RM850x 850W PSU 80+ Gold Fully Modular).

Which is better? And why? Or is there no difference?

Thanks in advance!

PFC is always a number below 1.  It's the "power factor" of the device.  If a power supply has "PFC" or "Power Factor Correction", then it should/would have a power factor of .95 or higher.  If something has a power factor lower than .95, it does not have power factor correction.

 

The 70.8A number you're quoting is the amount of POWER available on the +12V rail.  ex:  70.8 Amps X 12 Volts = 849.6 Watts
