How do you know if your PSU uses active PFC?

[Ready2Roll]

I want to get a UPS for my desktop. I understand that if my PSU uses active PFC, I need to get a UPS with pure sine wave output. I'd rather not do that if I don't have to since a pure sine wave UPS is more expensive than a simulated sine wave UPS.

I don't know what kind of PSU is installed in my desktop since it's not listed on any spec sheet I've seen, either in the original packaging or online. Therefore, I also don't know if it uses active PFC. The manufacturer hasn't been helpful in providing an answer. Is there some way for me to find out without taking the whole computer apart? Some indication I should look for on the label maybe? By the way, the desktop is a Lenovo IdeaCentre K330B 77472BU.

Welcome to Tom's Hardware Forums,
Your PSU, which is 260W is not an Active PFC model, most any UPS should work fine.
