Evaluation

We are using APW7 to run the X3 Antminer (which its rated Power is 500 W). We see that the power consumption of 490.8 W (on the left picture), so the load percentage is 490.8/1800 = 27.27%
Whereas using APW3++ to run X3 miner has a power consumption of 498.2 W (on the right picture), so the load percentage 498.2/1600=31.14%
We can conclude that APW7 could save around 4% of power used. This would reduce the cost of mining.

Temperature

Temperature measured at the placement area

Temperature measured on its metal casing:

APW7 has a better heat dissipation, which means APW7 can work in higher temperature environment.
