Just received my new 1th A1 28nm chip ASIC MINER. (video enclosed)

[andi1]

Hi guys i know theres a lot of folk waiting on buying a 1th machine now the older slower machines are quickly becoming obsolete and not generating as much coin.

My advice is if you thinking about it do it!

Ive been looking at the various 1th machines on offer over the past three weeks including the bitmain s2 but i decided take the dip on the A1 type and ordered one of the new A1 chip 1th machines from my supplying agent in china.  The machines looks to be a lot more better built than much of the stuff ive sen coming out of the china including the Avalon clones which seemed to break so easily and run too hot.  This machine runs a lot cooler than i expected and more stable too.  My garage is not some much of an oven as it used to be.  Speed wise its showing 1TH in back end and and at the pool eligus.  The back end cgi hybrid is in english and very simple to use with the ability to alter difficulty from between  4 and 1024.  Then you can access the usual network settings and your pool user and address etc.

The miner overall looks very well put together with sheathed thick ATX and PCIE power cables a cougar 1000w PSU which is modular.  Theres one power board inside the miner then a raspberry pi,  the raspberry has a sd card in it which I assume runs the hybrid cgi. No fancy LCD on this model but i like it because its more compact than the double stacked dragon miner that ive seen.  Power pull at the wall is 1057 watts so thats 1.57 wall per ghs

My only gripe is that it is still noisy compared to antminer but i assume this is down to the server grade high CFM delta 1.82A fans which are certainly pushing some air you can almost feel it lift the lid off when you undo the screws but i guess this is whats keeps  the unit so cool.  

Im so very happy with this miner so much so that ive just ordered another two.  Im just wondering about overclock now and if it would be possible maybe someone on here could look at a copy of the cgi thats on the raspberry pi

Heres a video on youtube of the ASIC:-

how big is that cougar psu? 1000 watts?  seems to me if a 1000 watt psu is pulling 1057 watts at the wall you are going to kill the psu.


 I think this is the psu http://www.newegg.com/Product/Product.aspx?Item=N82E16817553004

  has six rails  about 24 amps each . here is a review on a 700 watt version

 the  miner seems nice.,but I wish it did not come with a psu.

 I would drop this one into it.

Yea it would be better if they had the flexibility of fitting your own psu as its something a lot of people dont mind spending the extra on.

Just been reading the reviews on the cougar cx1000 it seems quite a few people have run them at 1000w 24/7 without an issue.   I guess a nice 1200watt unit would give some scope for an over clock

seems like the psu does go over its rating.  the review on the 700 watt shows that.  it is a power hungry psu.  it will do 80 percent on a high draw.

 the seasonic I listed does 88-90 percent  so your 1057 watts used would be more like 1057  x = 80/88   or 960 watts

so 100 watts is  2.4 k watts a day or 72 k watts a month at 18 cents a k watt that is 13 bucks a day  so  it would take a while to get the psu cost back in power.


But it would ship without it and be 7 pounds lighter.  makes shipping easy.


 I like the 4 blades inside vs 10 or so in the antminer s2.

Is that a Qiangminer unit ?

[davecoin]

Seems to be. It's the only one I've seen so far with a yellow pcb.

[philipma1957]

are these available in the usa? 

[andi1]

No its not from Qiangminer,  i have a guy in china whom ive worked with for over 3 years importing goods from China and he acts basically my english agent over there and sources anything i need.  He is based in Shenzhen which is obviously full of btc equipment so hes sourced it for me.

I have two more miners on there way to me which should be here in a week or so and this one is also up for sale if anyone in wanting one in the UK and would like to pick it up (or i could courier)

I now have a new version of this miner with 5 modules and capability to mine up 100ghs more it now mines to 1100 ghs Ive even seen 1.2 th!! ,  it uses a server style psu much better than the older version and the psu is 1400watts so plenty of headroom

Heres a picture of the latest model
