Hi:
Cards not showing or hashing.
One card is showing and hashing
One Card is showing and not hashing
One card os not showing at all.
See info below from log......does it look like cards not getting enough power.
Im running bitmain psu on 110v......
Any ideas?
Thanks!

Bitmain psu on 110 is only rated for 1200W max. I'll bet you're running a miner that needs more than that, right?

These aren't the Droids you're looking for: S5 & S7 (Sold), R4B2, R4B4 (RIP), 2x S9 obsolete, 2xS15-28, S17-56, S17-70

Absolutely. You're underpowering the miner and overloading the psu. I'd pick up another small psu and power one of the boards with that. Power the remaining boards and controller with the other. I'm running multiple thermaltake 750W psu since each cost only 60 bucks at frys! Mine on!  |

If you are intending to power your Antminer S9 with 2 110v PSU's make sure you you don't mix power supply sockets to the hash boards or you can destroy one of your boards. Make sure that the same PSU is powering one full board and not mix match between the 2.
In retrospect, its actually cheaper to get a 220v plug installed and buy the bitmain power supply, and it will save you electricity cost,
Cheers

Depends on which miner you have. If it's the s9 then, yes, you need a bigger psu. Even though EVGA makes a great psu, the 1300W model isn't going to cut it. You need the 1600W. From Bitmain's website S9 Power Consumption 1127W (11.5TH/s batch), 1225W (12.5TH/s batch), 1274W (13TH/s batch), 1323W (13.5TH/s batch), 1372W (14TH/s batch) (at the wall, with Bitmain’s APW3 PSU,93% efficiency, 25°C ambient temp). Expected discrepancy of +10% |

For S9's the best solution is to get 220V.
Agreed. If you can't do 220V, use 2 power supplies on 110v. Phil |

.is it possible to switch the cards physical order in the machine without hurting anything?
Yes, but you can just swap the connectors without moving the boards. |

Try this first, but from the log it looks like some of your chains are dead and the board isn't booting https://enforum.bitmain.com/bbs/topics/3957 |
