That's not really a proper way to deal with it. Proper UPS for a home server or any standalone server or appliance has to hook up either after ATX power supply in parallel and provide all the ATX voltages or hook up directly into a power supply to save a bit on extra converters. This way UPS failure won't affect anything and such UPS will be much more efficient.

It's just that consumer home UPSes are almost scam level products designed to profit from naive people. They are both not improving things for an average user and killing batteries after like a year of operation (lead acid batteries can last for like a decade when not subjected to those UPS chargers).

My cheapo UPS certainly improved things for me when I lived in an apartment where the entire unit minus kitchen appliances was wired to a single 15A circuit. I tripped the breaker semi-regularly by forgetting to turn off the AC before using the vacuum cleaner or toaster oven or whatever.
