...or use an 18AWG insulated copper wire (prettier than a paper clip) that's probably already in your junk parts drawer (or get a thermostat wire with strands of 18AWG wires in it from your local hardware store that cost a few cents per foot).  Cut about an inch long and shape into a "U" and strip the insulation at each end about a quarter inch.  Use the PSU's switch to turn the miner on or off...it's free!
