How many people here run a complete PC (Base unit, monitor, speakers and router/modem) from a single mains/wall socket using an extension? I've always heard people saying not to overload the socket, but i think a single 220-240V (UK 13A) mains socket with a 4-way extension would be perfectly fine, even if you do have a beast of a rig! I looked on the back of a 4-way surge protected extension and it says not to exceed 13A (3120 watts)... Just curious as i'm getting short on wall sockets in my office (aka gaming room ).
