Title: Useless piece of junk if you have Active Power Factor Correction (Active PFC)
Review: I had this UPC for several months and it seemed to work OK.The first time I had a power outage, I found that the PC reboots whenever the power goes out.It then fails over to battery and boots back up.I am informed by Customer Support that my PC power supply has Active Power FactorCorrection (Active PFC)which supposedly causes incompatible UPS units to make the PC reboot.When I bought the UPS here, it did not say anywhere ONLY WORKS WITH CERTAIN LIMITED PC POWER SUPPLIES, which now turns out to be the case.If you are just an average PC user that doesn't know squat about power supplies like I don't, LOOK OUT FOR THIS PRODUCT!If you expect your PC NOT to reboot when there is a blackout, STAY AWAY FROM THIS UPS or carefully check your power supply first.Also note that you cannot even return UPS to Amazon because of the battery, so expect to be STUCK WITH THIS PIECE OF JUNK.
