In my office I've got 2 computers, both with monitors and 2.1 speakers plus 2 printers, a scanner, a cable modem, a wireless transmitter (to transmit music to my home stereo at the other end of the house), a router, a fax machine, a TV, 2 fans, 2 lamps and probably a few things I've forgotten. These are plugged into two outlets (through surge protectors) which, I'm sure, are both on the same circuit. I think you're ok.
