Gino, can you say which gear? Most UPSes switch pretty much "instantly" (less than one AC cycle, which lasts 16ms) so a PSU that wouldn't last one AC cycle must have very questionable engineering. Or assuming that you use APC UPSes, you can change the sensitivity setting to switch quicker: http://www.apc.com/us/en/faqs/FA156514/
Even on the cheapest BackUPS, anything with a decent power supply is going to have capacitors with its own holdup time that's greater than any line interactive UPS. I've got some old late 90's vintage BackUPS units back when they were made out of metal still going strong.
If the power supply is a linear wall wart though, that could be a problem. ~Seth
