Cut off the roundy part of the power cord where it plugs into the wall/surge protector. Google "PS3 ground loop" and you'll find that that's the accepted cure for PS3 induced ground loops. Be warned that some folks will go "OMG you'll burn your house down" and others pay no mind to any percieved problem form floating the ground.
The stuff I've read on it was from Electricians and so forth, I've had mine configured that way for a year without incident.

The ground problem eminates from the PS3 having a grounded plug when none of the other electronics have that 3 prong style cord, they're all 2 prong. Hence a difference in grounding and the hum is induced at that point. In laymans terms.
