Max condition: 40℃, max J/TH, max hashrate.

Refers PSU power conversion efficiency of 93%.

(1‐4) Caution: Wrong input voltage may probably cause server damaged.

(1‐5) Typ condition: min reference power, typical DC input voltage.

Max condition: max reference power, min DC input voltage.

(1‐6) Min condition: 40℃, max J/TH, max hashrate,

PSU output power should be no less than the min value to make sure mining stable.

Typical condition: (typical power) = (min power)/90%, leave power output margin for PSU.

Caution: It is strongly recommended that using typical power can make sure your server can work well. You

can use one PSU to power multiple boards. Do not attempt to power one board with more than one PSU.All

PCI‐E ports are required to plug in while powering up the board.
