Alright, I have a Cyberpower Pure Sine Wave UPS for my main rig. Got that less than a year ago. Now I need another one for my wife's rig. Her's is similar to my current rig. And I believe her power supply is active PFC which I hear all the time should not be run on a regular UPS.

Is it true that you should run a pure sine wave UPS, and not a simulated one?

Secondly, what UPS would you recommend for a 650W PSU? Please include a link. Thanks.

Currently the three models I am currently considering:

  1. CyberPower CP1000PFCLCD PFC Compatible 1000VA 600W Pure Sine Wave Tower UPS @ 128
  2. APC BR1000G Back-UPS Pro 1000 Uninterruptible Power Supply @ $132
  3. CyberPower CP1350PFCLCD PFC Compatible 1350VA 810W Pure Sine Wave Tower UPS @ $160

Yes you are correct. Active PFC PSUs strictly require a pure sine wave UPS. Personally I'd go with the CyberPower CP1350PFCLCD you linked. Its 810 watt rating will provide some headroom for a monitor, router, desk lamp, etc. Its 1350VA high capacity battery will allow for longer outtages. It also has 10 plug outlets, and uses modern windows software which is a nice touch. The price is a little bit higher but certainly worth it.

I have no idea. I have heard it is hit and miss. But, no real clue.

I went with the CP1350. Should do the trick. I will probably buy the model or two below that in the coming months for my new Synology 412+.

Good choice! I have the 1350 and find it difficult to imagine being without it.

In fact, if I didn't have it, I wouldn't be able to post this right now, since the power is out at the moment. Heard the unmistakeable bang, through an open window, of a nearby transformer exploding, and down went the electricity. Thankfully, I've got plenty of battery time left to surf the web, maybe order some food, and generally go on with life.
