I'm looking for a UPS that produces a pure sine wave at the output because my PSU has active Power Factor Compensation and from what I read, it doesn't work with pseudo-sine wave output.

So, my system will draw a maximum of 430W with full load. I want just enough time to hibernate the system before it runs out of power. The UPS I'm looking for needs to be:

  • atleast 700 VA;
  • pure sine output;
  • under 150 €;
  • quality.
  • I don't know if a true sine wave output UPS is actually needed because of Active PFC, but I really don't think that all four criteria you listed can be met. You can probably find something that meets the three criteria except for the price, though, but I really doubt you will be able to find any true sine wave output UPS in your desired price range, and I can't imagine that you will find any true sine wave output UPS with that kind of power capability in your desired price range.

This seems to be what you are looking for. It is pure sine wave output, a modest price of $140, 1000 VA, and it is highly rated. It can't be internationally shipped from US Amazon, but this matches your criteria.
