I updated to the newest firmware as well. After about an hour, my S7 is performing a little better than standard spec and a couple degrees cooler than before the firmware upgrade.

Yes, it works in America. However, you need access to 208 to 240 Volts instead of 120 Volts. This would be a 2 poll breaker in the Main Service Panel and a minimum of 20 amps with 12 AWG wiring. If 2 poll 30 amp breaker, you need 10 AWG wiring. I don't think you are going higher than 30 Amps if you are installing a 240 volt outlet for the BMT 1600 watt PSU if you are in your home. I would suspect if you were in a data center, you would not have asked this question. 240 Volts is the way to go. You can run twice as many rigs than you can with 120 Volts. If you don't know what you're doing with electricity, get some help locally. |

Received an email, and UPS Tracking number
ordered on Oct 16th batch 3
will be delivered on Oct 28th according to UPS
I am wondering as to why batch 2 is like a foster child, always last to pay attention to. They can ship the miner until 10 of November... then it will be delayed, not before... My Batch1 was send last day  1. first of all, you got a wrong day, as +10 from oct 25 is Nov 4, NOT Nov 10. 2. why do you encourage this behavior? that's true...  I was thinking the batch 3 could delivered up to oct 30 (+ 10 days)... (batch 1 could up to sep 30)  |
Played with: USB RedFury - BlackArrows Prospero X1/X3 - Butterfly Monarch- Spondoolies SP20E - Avalon 6 - Antminer U3/S3/S3+/C1/S5/S7 Batches 3-7-8 - Sfards SF100 - Innosilicon A2 Terminator - Alcheminer 96/256 - KNC Titan - Etherum Rigs

That's right dmwardjr, I would have not given second thought about power calculation if I would have been purchase Colocation space. So that mean, I will have to arrange electrician to do that power adjustment if I was to use S7 and APW3-12-1600 PSU at my home? What if I buy this type of PSU http://www.frys.com/product/6806106?site=sr:SEARCH:MAIN_RSLT_PG then sure I don't need to do any changes above. Right? Thanks Again |

If more, 30A and PDU. |

If more, 30A and PDU. I think residential power distribution is different. 120V on wall socket. If I cannot use the recommended PSU by BITmain then what are my other options regarding PSU, if I wanted to start mining at home in America. What would you smart people suggest, who know how to calculate power. |

Kind reminder: When mining with S7, be sure that you've connected the internet properly and the internet is working well, otherwise, the boards may get burnt easily  I would not take this seriously. This message is not from Bitmain. They would have used proper channels, and not post a poorly written post on a forum, with an unknown username, lol! It is a Bitmain account, Janet's successor as she is off doing other things. I've asked them to add it to the BITMAIN signature. |

Yea that is a bit unnerving considering no ISP is 100% guaranteed and even my home router needs to be bounced once in a blue moon. |

If more, 30A and PDU. I agree. We just don't know if he's comfortable taking out a single pole 15 amp and replacing it with a 2 pole 15 amp. He might need to use a tandem breaker to make room in main service panel. He would have to make sure no other NON-240 Volt devices are plugged into the circuit to prevent potential fire. It would be best to have a dedicated circuit made just for the rig with its PSU. It's quite common for circuits to be looped (in a string) for receptacles (outlets), switches and lighting. I would be concerned about other devices connected to this circuit that would not handle the pressure of 240 Volts if someone were to accidentally plug a device not made for 240V at another outlet on the same loop as the circuit he upgraded to 240V. It's best IMHO to make (create) dedicated 240V circuits just for the mining rig(s) and PSU's to avoid possible fire from circuits plugged into looped outlets on the same circuit that were designed for 120 Volts. I've never tried plugging in a lamp [designed for 120V] in an outlet that was upgraded to 240 Volts. I have no idea what would occur. It may be you have experience with this and had no issues. I can't elaborate on that cause I really don't have experience. However, I'm usually one to go by the specifications laid out by the manufacturer of the appliance or light lamp. If the specifications state 120V @ 60 Hz with no mention of 240 Volts, I keep it only in 120 Volts. That's just me. Maybe I should check it out some time to see what would happen. However, I think I would run a line outside to the driveway to see what would occur as a precaution. |

Could get away with it... but I highly would not recommend doing it as I would guess a someone out there would try to do the breaker without the proper wiring. Which is not a good thing at all. I would recommend as well getting a 240 line dedicated for miners with wiring you know is proper gauge. It really is a better solution long term then trying to get away with other things that might not be quite as safe in long run. |

Thanks Again I would use one with more than 1200 watts. The S7 is rated at 1210 watts @ 600 MHz. You would have to under clock it for this PSU. Also, I would be concerned about the voltage provided by this PSU. I think you're better off getting an EVGA 1600 Supernova. After the 90 Day warranty, you might want to over clock your rig. You would be able to over clock it with the extra wattage provided by the EVGA 1600. For instance, if the Difficulty increased 8% in one month and the price of bitcoin increased 4% in the same month; [To avoid losing revenue] you could increase your hash rate by 4% by over clocking to generate the same amount of revenue that you were previously before the increase in difficulty that was not offset by the same amount of increase in bitcoin price. That was only an example. |

One PSU per blade with the third also powering the board. I have these PSU's sitting around after selling off the 3 S5's they were powering. |

You would be okay with 2 of those. Don't need 3. The only way you would need 3 is if the HX850 did not have a sufficient number of PCI-e connections. I'm not familiar with how many PCI-e connections the HX850 has. I have a lot of AX860's laying around. They have 8 PCI-e Connections on the back of the PSU. Make sure you use all 3 PCI-e cords on each blade because the gauge wire for the PCI-e cords provided with the HX850 PSU's are small compared to others that are custom made. If you had custom made PCI-e cords that are 16 gauge like mine, you would be fine with 2 PCI-e cords for each blade. That's my opinion. I used 2 Corsair AX860 Platinum PSU's to power one S7. It works fine. I did have to do a soft reboot after initial power up to get it to hash at 4.8 TH/s with low HW errors. |
