Anyone getting: Unknown error: null When trying to order the 1600 watt Power Supply? It's been this way for weeks.
I belive you have to pay with BTC not USD You PAY only with BITCOIN. I had to put 4 Pieces of em in cart till it worked to pay in USD

Thats a nice setup you got there. Deal with the heat ? HA ! I welcome the heat. I cherish the heat. I NEED the heat. For me, its the part of mining that has a 100% chance of ROI, it gets pretty darn cold up here in winter, and my setup place is in the garage, which is otherwise un-heated (i've blocked the central heating to the garage). It also heats the garage ceiling, which is the bedroom floor when you think about it. win-win. In summer, in really high temps I just shut them off. so thats maybe 1-2 weeks a year. the airplane turbine complaint is a valid one, come on. I'm not saying they have to be quiet - but around 70db (i believe) with high pitch noise...i mean people mod the fans on the s5. I'll just lower the manual fan setting a bit, end of story. Home mining does not mean 400 amps (did you tell your insurance...), it means a de-centralized network in a perfect world. Home mining is one rig. two rigs. 5 rigs. maybe 10 rigs. I wish everyone where I live had a bitcoin miner, all heat is pretty much electric anyways...

Thank you, it works for me. Totally agree. I like the heat as well except for the summer time. In summer, in really high temps I just shut them off. so thats maybe 1-2 weeks a year. the airplane turbine complaint is a valid one, come on.

I run my business [training telephone technicians] out of my home. I have business insurance for equipment in my home office. I need to upgrade my insurance to include more equipment. I have $25,000 insurance on office equipment at the moment. I only have 11 x S7's at the moment. So, I'm still covered for now. I will upgrade to $75,000 to cover the additional rigs I'm getting fairly soon. As for your "definition" of home mining; I'm probably about to re-define it. I did have 44 rigs in my home before I sold them to get S7's. I would not be surprised if there is someone out there already with 96,000 watts or more mining away in their garage.

Question about the S7...
Can you run S5 blades off of the S7? I have to get a new pcb for my S5, and I have a an S7 B7 on the way.

different chip count ? different freq ? different voltage ? i don't think so & NOT a good idea.

You can use S7 controller for S5 blades but with S5 software. You can connect 1-4 blades. With S5+ software you can connect 1-9 S5 blades. You can not use S7 software for this purpose.

100 x S7 = 120 kW !
How many seconds are time to ignites fire, when the fan stops ?
Do you actually think your negative connotations are getting you anywhere? Can one not have the means for power to shut off if smoke or fire is detected by a smoke/fire detector similar to a data center and fire extinguisher system installed that does not use water but smothers the fire with CO2 that leaves no white residue behind to ruin the rigs? The same thing is used in a mobile data center. What the hell does 120 kW have to do with the amount of time it takes for a fire to start? If done safely, there does not have to be a fire at all. EDIT: My feeder cable supplying power to my house is only capable of providing 500 amps to the house. I would have to spend another $5,200 to upgrade my feeder cable to the house to have enough power for 120 x S7's. I'm NOT doing that. I would rent/lease at another location before I spent that kind of money to upgrade my power here at the house. 400 amps of 500 amps would be used for mining in my home. The other 100 amps would power my AC, dryer, stove, fridge, LED lights, etc. That leaves me 96,000 watts for mining. Which would be 74 x Batch 8 S7's at 1,290 watts each OR 76 x Batch 5's at 1220 watts each. Who's to say we don't have a more power efficient rig in the future to allow me to have as many as 90 to 120 rigs instead of 74 rigs? Guys, How many S7 can I safely run on a 120amp setup ? Btw, since BITMAIN sell the PSUs without power cables do you all customised the PSU power cables or get them online?

120A if 240V = 28,800 Watts. 80% of that for code/safety margin is 23,040 W, or 18-19 Antminer S7's depending on model and clock.
For PSU's, I find Bitmain's over-priced for what you get. I am, however, biased towards the ones I sell.

I am in Asia using 220-240v read what finsky wrote. I just ordered some PSUs from him and has been very helpful with information on adpaters for plugs and such. I highly recommend contacting him. Also, way cheaper than the bitmain PSUs

1600W at 230V = 6.96A I buy mormal PC PSU power cords, which is rated -16A More recently, produced by the company LINDY www.LINDY.comThe same company 16A rated power cords I also use with DPS-2000 BB 2000W server PSUs. 200W at 230V = 8,7A

I couldn't find a reliable supplier for bulk purchase. hey i'm just across the causeway but a little further up but below genting lol. u can try server psu's like the one tupsu uses, i use them too. lots of power + adjustable voltage. the only issue is cooling it for most people. 2 x 2 2000bb's can power 3 x s7 comfortably with or without a breakout board or not. power is TOO expensive in sg mate ... no point mining in sg, you will not even make roi imo. please use good quality pcie cables. most of us are using custom made ones. try to find 16 awg cables. if you can't find them i have some spares. i have some spare server psu's too. @ tupsu, i got mine at 12.5V with load. much better than stock voltage. less or no hw error, stales, dupes, RUBBISH. thx for the info mate. i might up it a little according to BMT suggested : 12V + 5% = 12.6V with load plugged in when miner is mining. i'm waiting to see when the 90 day period ends & there must be some crazy people out there.

So......................bitcoin price is up, which makes the batch 8 (maybe the final form of the s7) quite expensive. over 1700usd. any regrets not ordering ? I got one at around 1500usd. In any case bitmaintech site is down. Hopefully they will start shipping batch 8 in advance like batch 7.

When the site goes down, a lot of times this means they are editing and/or adding something new. We'll see...
