Buying A UPS For PS3

I know the problem you are having and it is big a problem, because it's very possible you'd encounter the same problem even with a UPS that's just how the power supply in the PS3 is designed. It's very safe but the disadvantage is what you are experiencing it is VERY sensitive.

With the UPS, if it is the cheap ones that switches to battery power in loss of AC the same thing would happen as it may not switch in time to keep the PS3 on. (you would still get that delay.)

If it is a UPS that feeds the battery continuously and the battery feeds your devices you may have some more luck but depending on how much power the PS3 pulls you may get a small and temporary dip in voltage which may or may not cause the PS3's power supply safety features to kick in

If PS3 PSU is that sensitive then the only way would be to either buy Online UPS or maybe some kind of Line Interactive with AVR which is kinda pointless when you consider both of those are higher end UPSes and could cost as much as PS3 or more.

Also  if he gotten Online UPS I'm sure he wouldn't have problem since those machines give better voltage and frequency than you get from power grid :)
