Hey guys, I recently purchased a used s7 off ebay and it came with 2 power supplies. The issue i am having is that each power supply only has 8 pci connectors.

Is it a bad idea to only attach 2 connectors to each hash board? It seemes to boot up but I'm hesitant to run it like rhis..

What id like to know is 1. Is this at all risky? 2. Does this reduce the efficiency of my miner? If any of these are yes, what do you guys suggest as a power supply? The official bitmain one, or something else?

okay you don't want 2 psu's soooo easy to short the gear.

you can take 1 psu and run with 2 cable per board and one cable for the controller.

if the psu is rated for 1200 watts and you adjust the frequency down just a bit

if you lower the hash rate to about 4200 it would take about 1100 watts and would work.

the exact name and model of the psu's please
