PC Power supply and wall socket load saftey.?

I just ordered a mid tower rig, comes standard with an 800 watt PSU. I only have two outlets in my room and one within easy reach. The one within reach has a Monster brand wall expander/surge protector installed that divides the two traditional sockets into six separate sockets and two medium low USB ports.... show more I just ordered a mid tower rig, comes standard with an 800 watt PSU. I only have two outlets in my room and one within easy reach. The one within reach has a Monster brand wall expander/surge protector installed that divides the two traditional sockets into six separate sockets and two medium low USB ports. Currently my tv, sound bar, one computer, sub woofer, and PSTV are plugged in with a fourth computer on the way. Is it safe to plug a higher end PC with an 800 watt PSU into the Monster expander with an older rig, tv, sound bar, sub woofer, and PSTV also sharing space or should I consider migrating some of them to the other plug?
