Have used these speakers with a desktop PC for a month now, with no problems. Good value, good quality sound with plenty of volume, and stylish. Comes with its own power supply, and standard (green coded) jack that fits into the back of the PC. Had a bit of a scare when I first plugged them in as there was a dreadful hum, but that was quickly solved by pushing the jackplug firmly in to get a good contact - well worth checking this connection if you have (or read about) a humming problem! Well packed and excellent delivery service as usual from Amazon.
