Well I suppose it's time for me to get an uninterruptible power supply.. unfortunately I don't know very much about them, so I don't know what to choose. I'll need the following to be protected by the unit:

My computer (550w PSU)
cable modem
router
switch
my server, with a 300w psu (coming soon, will replace the router)


what kind of UPS should I get to keep all of those 'powered' up? Do I sound like an idiot?
