Okay, but like i said, to help you in your matter i need:
* to know your full system specs
* and your budget with location (e.g USA, Europe, Asia etc)
Since without full sys specs, i can't suggest proper wattage PSU. Unknown location would bring up the correct power sockets issue on UPS, e.g i suggest a good UPS which has Schuko sockets while what you have in use are actually NEMA sockets. And lastly, everybody has a budget. Else-ways, go and get high-end, rack mountable, 2000VA, online UPS with true/pure sine wave output.
