Running two UPS backups for my overclocked SLI system

I recently bought a CyberPower 1350AVR thinking it would be enough to power my system (specs in sig), a 37" HDTV LCD I use for a main monitor, cable modem, and router. I was wrong. It didn't take long for me to get overload warning beeps testing my system out at full load. With just my PC connected to the UPS the LCD shows a max output of ~725W at full load. Close to the max 810W of the UPS. At desktop with a web browser open it stays between 250W and 300W. With just the LCD and everything else connected it maxed out at 200W. I was thinking of keeping this UPS and getting a CyberPower 1500AVR to go along with it. The PC would be connected to the 1500AVR and everything else would be connected to the 1350AVR. Any thoughts?
 
I've been reading about active PFC and these UPS units thanks to a thread on here. Some say the simulated sine wave of these particular UPS units are a bad combination for active PFC power supplies. I've had the AC power cut off on the UPS with my PC connected. I did not notice any issues with overload or anything else on the CyberPower UPS, so I'm not sure what to think. Some rudimentary Google searching revealed others using active PFC power supplied on simulated sine wave UPS units.
