Motherboard for 8 gpu mining rig

[beks1]

I have EVGA 1600w G2 PSU,

I heard that MSI 270 supports 8 card is it true?

I don’t know about 8 but there are multiple 6 ones and couple of 7 ones I know of.
ASUS Z9PE-D8 WS Dual LGA 2011 Intel C602 SATA 6Gb/s USB 3.0 SSI EEB Intel Motherboard, supports 7 I think and there is ASUS P9X79-E WS LGA 2011 Intel X79 SATA 6Gb/s USB 3.0 SSI CEB Intel Motherboard which supports 7 as well. These are the highest ones I know with 7, don’t remember if there is any 8.

Do you have 8 GPUs on your rig?

It should.

I have 7 GPU rig which pulls 1050 (ETH only) at the wall. (ETH+DCR) it pulls around 1350.

The system when not mining it pulls around 175w

It would be about 73% load.

Don't forget about efficiency losses when you get to the high end of the curve.

I'm trying to run all my rigs on 220v between 50%-70%. This will get my efficiency up to 92% with only a gold rated PSU
