Exclusive First Official Hands On In North America With The Bitmain Antminer S3

I have North America’s first official pictures of the Bitmain Antminer S3. Scott of HolyBitcoin was the first customer to receive his S3 today.  For him, it is exciting to be the first to have new miners in hand and Scott did not let me down: He sent me lots of pics to share with you all.  For those not familiar with Antminer’s newest miner, here are the current specs of the Antminer S3 Bitcoin ASIC Miner.

Hash Rate: 440 GH/s±5%
Power Consumption: 366 Watt at the wall
Power Efficiency: 0.77 J/GH on wall
16 chips a blade 32 chips total
218.75 freq
4 PCIe Power connections. two for normal operation and four ports for overclocking.
Size: 331 mm x 137 mm x 160 mm
Dual Inlet and Outlet Fans
Operating Temperature: 0 °C to 35°C
Complied with: FCC / CE


The arrival of the S3 stateside is great news as it means that they are hitting the hands of vendors and customers as we speak. This first look at the Antminer S3 is possible thanks to Juan at 112bit who works hard to get miners in customers’s hands as soon as possible.

S3 Miner Status

The standard operating setup is familiar to anyone who has used a Bitmain miner before. The login IP is default, and this can be changed as usual in the dashboard. The dashboard is the same and works just as well as before. The S3 comes packaged in a single-box and securely foam seated as well as wrapped inside.
Packaging like this should allow for safe shipping all over. The compact size of the unit is also excellent for shipping large quantities of miners at once saving on shipping costs. Scott of HolyBitcoin has stated the fan noise is roughly on par with the S1, which is great news as many were worried about noise with the new dual fan design. The enclosed blade design allows for a better air tunnel for more efficient cooling. Scott does mention that due to the case design, units will have to be stacked on their sides as opposed to top and bottom like the S1. The S3 has its PCIe connections on the top.

I will have a full review of the Antminer S3 in the next couple days. In the meantime, Scott was gracious enough to share with me some pictures of his S3 as well as his initial testing results.


First to report are the initial power results from Scott. 3.16 amps at 366 watts on 110v via a KillOWatt meter. So not to bad results power wise.

At those power specs he gets 450gh/s rate internally and hits 450gh/s to 451 gh/s poolside. He was able to get 340W from the wall with a good Corsair PSU. The results are good news as it highlights Bitmain’s software’s continued stability.

I asked Scott his thoughts on the S3:

“The Antminer S3 has an even better power draw than the classic S1 design, with 2.5X more performance. If the S1 was known as a Tank, the S3 in its new case has got to be a battleship!”

Bitmain recently had announced a retarget of the S3s performance and has issued a compensation plan. Scott has also iterated that he will do the same.

“I am going to match Bitmains Offer for either a 7.7% refund or a 10% coupon for a future order. I still have a limited amount of batch 1 units available for pre-order, which are sure to sell out quickly!”


Juan from, the Authorized Bitmain Distributor, had to say this about the Antminer S3 launch.

“Sales of the S3 have been great the first Batch sold out quickly and demand for the next is already very high.  Antminer S3 lets even small miners to access to the same technology and efficiency that high-end mining operations have and is the most competitive mining hardware in the market.”

I want to thank Juan and Scott for giving us the first pics and reactions to the S3.
The ability to overclock your S3 just like the S1 will be a big draw for enthusiasts and the same great solid and easy to use setup of the S3 will also help new miners be able to enjoy mining as well. The price is right for the S3. Like the S1, adoption should happen quickly and Bitmain ships in quantities instead of long pre-orders that never ship like BFL, KnC and others.
