[Antminer S1 Sales open] Price changes daily, now 0.414 BTC for 180GH/s

[Unacceptable]

OK...maybe this is a noob question, but i have been getting my PSUs from NewEgg as well (my all time favorite seller of computer parts and various electronic gizmos).  However, I've been buying name brand PSUs in the 500-550W range.  One Thermaltake for $34 after rebate, one Corsair for $30 after rebate and I'm about to buy an EVGA for $30 after rebate -- all with free shipping.  Link for EVGA PSU here:

http://www.newegg.com/Product/Product.aspx?Item=N82E16817438016

They all have 3+ year warranties and the two I own seem to work just fine with the S1 (admittedly I have not yet overclocked the two I own so far)...why are you all buying the big power supplies to run multiple miners?  It seems to me if a big PSU does fail, you have multiple miners out of commission. Maybe I'm missing something?

How are you running an Ant on this PSU It has only 1 PCIE cable with 2 connectors............you using a dual 4pin molex to 6pin PCIE adapter,or both blades on the one cable   Not a good idea if you are 

I prefer the Corsair CX600,it has 2 separate PCIE cables.So does the CX500   

I use 2 of those EVGA KR 500 with single 40A rail. Each one running like champs on each their own S1s to power. They are so inexpensive I just cut the CPU plug and spliced it into one of the S1 blade and used the PCI-E plug for the other blade. Running like great 2 months now. Also both S1 over clocked 375. no need to spend top dollar. EVGA make solid PS

Ok,very clever !!!

? What's the problem with a single PCIE cable with two connectors?  The Thermaltake PSU ($35) I've been running rock solid  for two weeks now has one cable with two PCIE connectors.  Both the Thermaltake and the EVGA (Just ordered for $30 after rebate) have a single 42 and 40 amp +12V rail (respectively).  These may not be the best PSUs on the planet, but the Thermaltake seems to work just fine, and I expect the same from the EVGA PSU.  These PSUs were, after all, designed to run two video cards with potentially similar draws to the two S1 blades....My other PSU is a Corsair CX500, works just fine as well with two cables/PCIE connectors.

Is the concern wire gauge / fire hazard? While I have not done the math, the cable on the Thermaltake is just warm to the touch (my Starbucks coffee is way hotter .

Date stamp on my order details says 4-8-2014, not sure if that was my day or theirs, waiting to hear back on a shipping inquiry...

yeah, thats the issue. by running a full antminer on only a single wire lead (2 heads) you are putting 360W+ through only 3 wire pairs. Most 18awg wires cant handle this (so yours might be 16awg), and there are past reports of these sort of power connectors failing if overloaded.

If you go throught the bitfury threads, there are a lot of reports from users that used a similar PSU to run >400W to the bitfury board and ended up with small fires or melted wires.

just be mindful of the wire temperatures. If they get any warmer than 'warm' you start increasing the risk of it failing. higher temperatures can create higher resistance and increase the voltage drop, further increasing the amperage pulled by the hardware. If its just a very mild warmth then maybe putting a little airflow nearby will make sure it doesnt become a problem

While the part in bold is true, they likely didn't intend for them to drive two video cards at full power 24x7, such as your ant is doing.

Thanks.  I will definitely keep an eye (or finger) on the wire temps.  

I did do a bit of research and it looks like it is fine to pull 30A through 3' of 18AWG...with the PCIE connectors we have 3 pair of (at least) 18AWG about 2' in length...seems like it should be OK...but I will still take the words of caution seriously.  The below table may help others.

Yes,the cable itself is not rated for 400 watts,24hrs a day/7days a week/365 days a year,it MAY melt & COULD start a fire & maybe fry the miner too.Vid cards while gaming use NO WHERE near what these miners use.Even GPU's used for mining use about 30% more mining than gaming or video editing.  

300 watts per cable is about the max you want pull on that cable.So be careful

I'm looking at replacing the fans on the ants, as they're in my office and at full speed, can be a little too loud 
Now, will this fan suffice?

http://www.quietpc.com/nx-120-pwm

Or recommend a decent, quiet replacement?

[qosmio]

quiet fans = less wind = less cooling , better leave original

Anyone else order a few days ago but not get any shipping info??

It's 100% normal to receive the actual unit before BITMAIN updates the website.  Don't sweat it.

Thanks for the reply, eases my mind...

Can you only order S1s with BTC? Is there a credit card option?

if you have access to 'myUps'  you will see the projected delivery of the ant 2 days before arrival.

No credit card option, BTC only. My recommendation would be to buy a coin on localbitcoins.com or some other reputable site.

Don't replace the original, simply add another, quieter fan on the other end, that'll slow down the main fan and make it quieter overall

From Bitmain directly you can only use BTC. You can buy from resellers though. For example, last time I looked there were some for sale from third parties on amazon.com

I've purchased an S1 and my S2 through 112bit.com--Juan G. (topminingcontracts on here) is much quicker to communicate with than bitmaintech directly.  He doesn't take credit card directly but will do escrow.  Instead, you order and then deposit money into an account (or wire it, if you choose... some banks have reasonable wire fees less than $15 but some are pretty overpriced). 

There are several posts about 112bit if you don't want to take my word.  The other options are eBay and Amazon but you probably won't get the best deals there.  The best option is definitely using BTC.  You can convert USD to BTC through like coinbase.com (or others, I am sure).

in the past bitmain shipped faster, still waiting for update for my april 9 order

Anyone running 3 S1 on a seasonic? I need help!

I keep getting the psu going into some sort of protection mode...ie no power after running for 10 minutes.

My PCI-E are plugged into the lower right 3 PCI-E slots.

Running 2 units seems ok. PSU is 1250W, 2 units stock, 1 unit OC 375.
