As we are building 6 GPU RTX 3080 Mining rig, we would be requiring 6 GPU's. Combining which we would be generating – 90 * 6 = 540MH/s. Total power consumed would be = 220 * 6 = 1320W. *Power of the GPU stated in the article is when it is undervolted and overclocked. I have used MSI afterburner to achieve this.
