Antminer s7 wont work with bitmain APW3++

[Marvell2]

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 ?

I assume you have 220V or greater mains voltage, since you seem to be using this 4k kit http://holybitcoin.com/product/dps-2000bb-dual-4k-breakout-adapter-board/    or similar other kit.

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.

I have a couple of the PSUs in the January batch act up in a similar fashion. I've had luck with power cycling them a few times.

Yeah plug and unplug, I had to do it up to 3 times on some. Perhaps try another plug?

The APW3 is a terrible power  supply. 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.

so i unplugged it for like an hour, plugged it in then it worked wtf
The other one i returned from ebay didnt start at all though so this one seems to be working
btw the s7 is really taxing the unit, its pulling 6.4 amps at 240 jeez
