ET PC Computers introduces a device designed to allow you to power two Gridseed or GAW ASIC Miners through an ATX power supply. Simply plug the 4-pin molex into an appropriate slot on your power supply, and attach the 2.1mm DC power plugs to your Gridseed or GAW miners, and you're good to go. For safety reasons, we strongly recommend not using more than one splitter per 12V ATX rail!
 

Power two units on one 12 volt rail of an ATX power supply!

Save wall plugs with as many as 6 ASICs on one high end PC PSU
