It sounds like the UPS is not switching in fast enough for your PSU to maintain the power.
Have you checked the UPS options to see if anything can be changed to improve it?
Your PC PSU could be poor quality as some do not smooth the power supply very well. I did have a cheap PSU that came with a PC case and the PC that it powered rebooted when there was a brown out one night. My main PC with a good quality PSU came through it without a problem. That was before I got a APC SmartUPS and that does have options for voltage which can be changed.
