- Some server PSUs will not work with a UPS that uses a simulated sine wave output. Some PSUs don’t seem to mind. The reasons are beyond the scope of this guide. I have seen the output of some simulated sine wave UPSs on an oscilloscope and some of them are shockingly bad and do not even come close to a sine wave. If you don’t want to take a chance, then get a UPS that provides a proper sine wave at its output. Unfortunately, | - Some server PSUs will not work with a UPS that uses a simulated sine wave output.
