[BluffTHIS!]

Your power supply should be more than adequate for that configuration, although it is possible it is malfunctioning and thus the cause of your problems. I use a Belkin 550VA battery backup w/surge suppressor (around $80) that has 6 outlets total, 4 of which are backed up while the other two are not. It is advisable to plug printers into those that are not, leaving battery power for the computer and monitor and dsl modem, so that it can last longer and give you more time to shutdown if necessary. Regarding your TV and other devices, it is probably best to just get an electrician to install a whole house surge suppressor for all your appliances if you own your own home. If not then you can buy small individual outlet surge suppressors.
