APC usually makes decent UPS devices. However, these two are two of the cheaper models out there and they utilize a stepped approximation to a sine wave rather than pulse wave modulation which may or may not play nicely with your power supply. Most other devices dont seem to care much.

Active PFC (Power Factor Correcting) in high end PSU's does not play well with these cheaper UPS.

I own a CP UPS. The ones you listed also suffer from being simulated sine-wave. For the TV and Playstation, theyll be fine. For a PC itll depend on your PSU
