5 Bitmain Antminer L3+ 504 MH/s with APW3++ 1600w Power Supply
These units have had their voltages tuned and draw 675watts @120v in a 20degree C room, they will be slightly more efficient @240V (my watt meter only works on 120V)
They hash at 504 MH/s with 0.05% hardware errors (+ or - 0.005%).
They are used and were run in an air filtered environment, in the summer they were unplugged when the chip temps went above 66 deg C, they were too loud and I like my neighbors.
$200 USD ea w/PSU plus shipping (from Canada) E-transfer or crypto (BTC, LTC, ETH)
Shipping in original packaging.
Forum escrow if required.
