That is strange. Only thing I can think of is maybe the PSUs don't like the UPS' AVR, but that still doesn't make sense to me. Are you saying the PSUs won't run on the UPS at all, or just while it's running off the battery? If they don't work with it at all, then it has nothing to do with the simulated sine wave output since that only applies when the inverter is active (otherwise the output is just the mains power run through a voltage regulator, so the waveform isn't changed).
