Topic: ANTMINER S7 is available at bitmaintech.com with 4.86TH/s, 0.25J/GH - page 193. (Read 527809 times)

I saw that some are using this PSU EVGA SuperNOVA 1300 G2 1300W for their S7. How's it working out?

Maybe Batch 3 is on hand and ready to ship because they were available for the orders that weren't shipped? Batch 7 and 8 won't arrive for about 1 month or more. So a Batch 3 arriving by the end of next week should be a better.

thats weird.  but just looking at the price, wouldnt a batch 8 be better ?

markings? you mean PCIe cables or power cable?

if you talking about PCIE (12v) or power cables (110/120V), here is the relevant reference:
http://www.rowand.net/Shop/Tech/WireCapacityChart.htm
get to the bottom of that page
it says:

at 12V 20awg 8amp max per wire, but PCIe has two, so 8X2X12=192W as far as wire carrying capacity is concerned. 192X9=1728W, much more than 1210W S7, so according to this, even 20awg wire is OK, but most good ATX PSU have at least 18 gauge wire (can carry 10A ea at 12V)

at 110V 20awg-only 7.5A, so you need 14-16awg power cable, 18awg is too low as 1250w/110v=11.36A, which exceeds 10A limit for 18awg cord.
You get half a current at 220V though.

wolfen.... i cant find m's miner monitor to download on the internet. I have setup Teamviewer free version, andf would like to have a glance of all miners, their online status, temp etc. Can Help?

What is the safest standard markings good to use for S7s?

Can I use this: 10Amp 18AWG ?

Do you really need to change your miners default password if you changed your router password? I don't see how anybody can get in. You also can't access the router remotely.

I'm not sure what the wire gauge number is on the Bitmain power supplies, someone will have to see if there is some printing on the wires and post the AWG size.

BUT, for reference, when I made the cables for the DPS-1200FB power supplies I have, I used 20ga wire.... its what I had laying around that would fit the pins I have.... Calculating the load per wire,  I divided the maximum amperage the power supply could produce across the 6 Molex plugs, the amperage per pin/wire was 5.5 amp.... WELL within the specification for the wire size and insulation type using an NEC wire chart.

YES, insulation type is also a factor. You can have anything from varnish coated wires, plastic insulated, silicone insulated, or even teflon insulated. Some insulation melts at lower temps, so if you have a Molex connector that heating up because of old age or you have been plugging and unplugging a lot and you have cheap ass plastic insulated wires, more likely you will have a meltdown from insulation melting then wires shorting out than if you were running a smaller wire gauge, same amperage, and teflon insulation.

You might think silicone insulated wires will handle the heat... somewhat. Silicone insulation is used when maximum flexability is required, or is in a higher heat environment, or is carrying higher voltage (think 1000V or more). Silicone insulation is not very good when its in direct contact with a high temperature material such as a wire which has a contact that is micro arcing causing the wire to heat up massively.... it will melt with relative ease.

I have used it for two years.
The trick is to have a pc at the remote site . Just a cheap laptop would do it. Can't tell you the pile I have of those.
I have two pc's at my remote just incase one gets funny.
No router configuration or port forwarding.
Teamviewer guys just dont want you controlling 10 pc's at the same time unless you pay. One or two.
I know I got it to work on ubuntu also. Don't think I would put it on the beaglebone on the antminer.
I use m's miner monitor or  multiminer on the pc. m's multi miner allows you to see what the stats were when it stopped working.
40 miner stats at a glance.
M's miner monitor will reboot using SSH

Seems like a few Batch 3 are available for 5.08 BTC. Someone must not have paid for their order.

Yeah, the price of gear these days is a bit absurd. $1,600 plus is a lot for something that probably only cost Bitmain $100 more to make than gear that they sold for $300. I'm quite amazed that they have no competition selling to the public right now.

Whats most amazing is that the miners these days use so much more electricity than previous models to mine a single coin its insane. Even with 0.25W/Gh you need 10Kw and $7,000+ in gear and PSUs just to earn .25Btc per day. Its about to get a lot worse in the next few months too. If we do a few more 10% jumps were all going to be mining at a loss soon enough... 

yeah its insane, but if i remember correctly (maybe im wrong) diff increases were brutal in the s1 days.  I bought an s1 and that made great roi, it was running next to a couple gpu's who were mining alts.  good days
