You need a UPS that outputs a true sine wave such as a smart ups. Using a regular simulated sine wave ups can kill your PSU.

Some active PFC PSUs will have a problem with it. It's best to check with the manufacturer of the power supply. For North Americans, the best solution is to simply get a non-PFC power supply. Efficiency and having PFC is not related, so there's no direct benefit to having active PFC.

If you can't find an active PFC power supply whose manufacturer can promise compatibility with modified square wave, it's cheaper to buy a power supply to accommodate your UPS than the other way around.

In Europe, there's no choice. It's a regulatory requirement

I just bought a new PSU and recently researched this issue. Some units have a problem and some do not. From what I have read the Hiper is not compatible. Seasonic units seem to be compatible but there is no official documentation that I have found that states so. According to a moderator on the Corsair forum, corsair units do not have a problem with simulated sine waves.

The FAQ on the Enermax site say do not use an active PFC unit with anything other than a pure sine wave UPS; however, the manual of my new Enermax Modu82+ 425 watt PSU states *"This power supply is compatible with both simulated and pure sime wave UPS."*
