I have 3 Supra Hex 703’s and 2 Gamma 601s for sale. they all have a pre wired dedicated power supply that comes with them. theyve been ran for about 3 months off and on. Just looking for another hobby. They all work as they should. Due to the unpredictability of over clocking units, all sales are final. no returns accepted. These miners work and have pulled blocks on smaller crypto currency. The price is the lot and power supplies all together.
