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

Can I use this: 10Amp 18AWG ?

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.

thanks Biodom.

I was referring to the power cables.

I am on 220/240v country, so as per your guide, minimum 10A at 18AWG (ATX PSU standard power cable), correct?

This one should be ok too, 13Amp 18AWG https://www.amazon.com/gp/product/B007FHQZLO/ref=od_aui_detailpages00?ie=UTF8&psc=1

I made S7 orders and order list says : Paid Unshipped Expired . I made payment 10 minutes after I got order details, is this normal?

The other paid batch 8 order is : Paid Unshipped Valid and There is edit button in it.

You should mail bitmain regarding your order they should fix it as valid

ANTMINER S7 BATCH 7 - Sold Out - are FOR SALE!!!!  

gone again

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

https://www.bitmaintech.com/productDetail.htm?pid=000201509290954354994vrQh8di06E6

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

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.

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

[elokk]

 I never have luck getting an order through Bitmain before a batch sells out so I spend more and purchase some of my gear off Amazon. Recently I pre-ordered two Batch 5 S7 from a seller named BitVet who assured me he had plenty units secured from Bitmain. Well as of yesterday he cancelled both of my pre-orders and will not respond to my messages. Just wanted to give a heads up so nobody else here has their time wasted by this dishonest seller. Looks like other buyers had the same thing happen to them as well.

Guys you won't get a batch 3 order if you place your order now through that link.. Bitmain told me about this glitch and said look at the web URL and its date, and the shipping dates.  It's an error on their part as they forgot to take down the page.

fantastic-no probs so far, but you need two PCIe extenders that you connect to singles and then balance the load.
I do it it the following way:
first row: Position 1 and 2-two connectors from double headed red cable, Position 3-one connector from a "single" that was split with an extender cable
second row: Position 1 and 2-two connectors from double headed red cable and Position 3-second connector from an extender
third row: Pos1-single red cable, Pos2-single red cable, Pos3-first connector of the second extender connected to a single red cable
Controller-second connector of the second extender

I bought extenders from either Startech (they are 50% more expensive, but connect very snugly) or Jacobs parts-those do the job, but sometimes take a few seconds to fit them. Both are 18 awg, which is enough for the task.
Startech-$6/cable
Jacobs parts-$3.95/cable on amazon -search for "PCIE split cables"

Ya they were just lazy there and modded the text instead of pulling the page or taking down the buy link

I'm using a G2 1300W as well to power my S7. It's been running for a few weeks now with no major issues. However the one problem I've been having with my setup is that whenever I have a power failure, the PSU won't boot up again automatically when power comes back online. If I want to start up my miner again, I have to pull out the paper clip jumper and pop it back in again. So that's something to keep in mind if you live somewhere like me where power failures aren't uncommon. Other than that I'm really pleased with the G2 1300W.

I got mine running now and they did not let me down.

Easy setup as i am used to. Just adding a pool and voila, my miners are hashing away.

[yslyung]

hashrates are pretty jumpy ? all over the place . . . me no likey

I try to pay for my order with USD and I get this error : Can not buy different currency once

How can I pay with USD wire ?

Are you buying PSU on the same cart as well? If yes, that might be an issue, try placing orders separately.

Contact their support (you need an account for this)
https://passport.bitmain.com/login?service=https%3A%2F%2Fsupport.bitmain.com%2F%3Futm_source%3Dforum

Else you can mail them directly:
https://www.bitmaintech.com/about.htm

Most probaly they have to fix a bug and will allow you to place a manual order.

Where are you seeing an order list? I ordered one Batch 7 as well when the orders re-opened the other day, and would like to check to see if my order reflects the same status. I received an email from the webmaster@bitmaintech.com website stating Order Paid, so would like to think that I'm fine.

Just waiting on a reply from Finksy regarding the Server PSU breakout boards and would hate to purchase everything only to have my order canceled due to an error with Bitmains system.....

I went through the order process for the B7 for many units.....It was confirmed by Bitmain with the "Batch 7-sold out."  Should be no problem with the B7s

Thx. It will be interesting to see how they deal with this as i placed an order (and paid for it) for a Batch 3 last night.
