If both the UPS and your power supply are commercial products carrying UL or CE or both there would be no problem. There are requirements for the power supply to continue working with full load for at least one half cycle (10ms for 50Hz) without mains. Also the requirements for the UPS say that it should start to supply power for less than one half cycle.
PC PSU's only store energy for 1 cycle minimum at full load. Thus if offline switcher causes. large dropout, it will fault some PC's.
This is why online UPS is best.
Offline UPS is just a life preserver for most but not all loads like Laser printers. Whereas Online UPS is a better "generator" with low Z and better load regulation.
There are 3 types of UPS
- Offline ... good
- Offline interactive... better
- Online , dual converters.... best
There are 5 types of DCDC converters used in UPS each with different cost, loss, surge and impedance load regulation tradeoffs.
- Forward Converter
- Push-Pull Converter
- Half-Bridge Converter
- Full-Bridge Converter
- Flyback Converter ... cheapest
