I was wondering whether ya'll think I would trip a breaker / create an unsafe situation with the following items plugged into one wall socket. The building is about 30 years old, but I don't know about the electrical system.

In approximate order:

Computer with 550 watt power supply
Computer with 250 watt power supply
100 watt speaker system
21" monitor
17" monitor
75 watt bulb
50 wat bulb
Inkjet printer
5 other devices totaling about 100 watts

Should I be concerned?
