UPS recommendations home/gaming PC in 2025?

They're all clearly labelled as being designed to provide runtime during power failure. :)

they are. for the few minutes they can do at max load. they give you the breathing space to safely shutdown the equipment being protected.

that you can run very low power devices for 'extended' runtimes is an bonus.
 
I'm just pulling your chain.... :)

In your case you're probably trying to source power sources designed as fail-over to keep infrastructure running during a power failure, and yeah, these aren't going to do that outside of giving you the time to safely shut down. OTOH, if it's just a single server then a larger unit would give a longer period of time for a safe shutdown and conceivably allow for bridge power if the power outage is short. (My unraid box safe shutdown has the option to select a safe shutdown after X period of time after it starts using the battery backup which is set to something like 15 minutes so if the power came back on before that it would continue on without shutting down).

Why? I was going to get one for my tv and stereo.

"150-watt RMS amplifier (300 watts peak power)"

A 1500VA UPS can only handle about 1000-1100W of actual draw even when it has power before alarms will go off. Overclocked 1100T + Quadfire 6990s (also overclocked) would draw around 1150W from the wall excluding the monitors and speakers and constant alarms on the UPS when it was loaded like that.

So a stereo large enough might not have an RMS quite that large but your peak wattage draws might keep constantly tripping alarms especially when combined with additional stuff like a large TV, console and whatever else you might have hooked up.

A UPS constantly bouncing off that overdraw state will not last as long. A smaller setup that doesn't keep hitting the overdraw state will not be an issue.
 
I tried my "spare" 1000VA UPS on my tankless water heater, it would keep it running if the hot water was already running when I flipped the breaker, but if I turned the tap off and tried to get hot water again while the breaker was off, nope! UPS instantly powered off.

It's really only a fan, so didn't make much sense, but I guess UPS's aren't designed for sudden inrush of power.
 
IIRC, there's also an issue with UPS not working correctly with anything relating to electric motors. You can't power things like sump pumps so it's possible that a "fan" might fall under that category.
