I do not have a wattmeter, but i noticed that EWBF’s miner shows almost same watt reading as **Corsair Link** in other rigs.

**Corsair Link** is a software that works with top end Corsair PSU’s (AX1500i is one of them) and shows exact in/out watt usage, try to see if you can refund the wattmeter as you don’t need one

Example from my AX1200i from another rig
