The Active PFC issue has the potential to affect all UPS's that aren't true sine wave. That said, my APC XS1500 has worked find for years with my APFC Antec NeoPower HE 550. My problem with CyberPower is that their pure sine wave UPS PP1500SW-T2 tripped the AFCI breaker in my house as soon as it was powered on. It did so in every room equipped with AFCI, including my home office, where the APC has no problem. I had to return the CyberPower to Amazon as it was incompatible with my brand new house.
It's really starting to seem like everything I buy lately is abject crap, from a noisy Antec Signature 650 to a buggy Denon receiver to a new i5 750 system which is maddeningly unstable. I'm about sick of electronics.
ETA: I can't believe I forgot the noisy-ass GE refrigerator I bought from "Home Depot", who refused to take the piece of crap back. That was the third "Energy Star" piece of crap I tried, LG and Samsung models having been returned to Best Buy for being so much noisier than the 15 year old Kitchenaid they were to replace. Unfortunately, "Energy Star" garbage is all you can buy these days. The government actually claims that "Energy Star" compressors run less and are quieter than old compressors, which are just outrageous lies. My 15 y/o Kitchenaid, whose icemaker broke, has been relegated to the garage, where in an ambient summer environment of 90F, it runs less and is quieter than the three "Energy Star" pieces of crap I tried in my 73F house. All I can say is that I'll never shop at "Home Depot" again, having been lied to by multiple salespeople about their return policy, and after their manager refused to honor the return policy that was plainly displayed on a giant sign.
