Title: Antminer s7 wont work with bitmain APW3++ Post by: Marvell2 on January 18, 2018, 10:22:56 AM So this antminer works with my 4k breakout board kits but i got my hands on a new APW3++ plugged in all the pci-e connectors inculding controller board and connected the APW3++ to power. The fans on it spin so it seems that the PSU is active but the s7 wont turn on ? any ideas ?

So the mains voltage is not the issue. APW3++ is able to handle max. 1200W power capacity at 110V and max. 1600W power capacity at 220V mains voltage. Sounds a lot like the APW3++ psu is faulty.

In large bulk orders I have seen 30%+ failure rates. You need to verify the PSU is putting 12v out of the power plugs. Just because the fans running does not mean the PSU is actually putting the power out.
