The Bitcoin ASIC manufacturer Spondoolies Tech is targeting the home miners with the new price of their 1.7 THS SP20 Jackson Bitcoin ASIC miner that is now available for a price of $795 USD with the November Batch 1 of the miner starting to ship on November 18th. The SP20 Jackson SHA-256 ASIC miner consists of 8 28nm Spondoolies-Tech RockerBox ASICs, comes with a dedicated Linux-based controller box that uses an Ethernet port for connecting the miner to your network. The miner does not come with a built-in power supply, you will need to add an external one that will be connected to the ASIC via 4 6-pin PCI-E connectors and it would need a minimum 1200W high quality PSU (1152 Watts actual power used according to the manufacturer). The one thing that is not very clear about the SP20 ASIC miner is what is he level of noise the cooling of the device produces (hopefully less than 60 Decibels), as in order to be suitable for home mining it should not be as loud as a server. Spondoolies Tech is probably not a know name for some of you as the company specializes in miners that are mostly used by larger mining operations and is also the supplier of some big cloud mining operations such as Genesis Mining for example. We suspect that the noise level at the listed power specification will not be very low, so do have in mind if you are interested in getting one of these to mine at home with.

MinerEU is now offering to its customers from Europe some of the Rockminer SHA-256 ASIC miners available at attractive prices and shipped from UK, so no extra taxes need to be paid. The small 100-110 GHS Rockminer RBOX miners are available for $145 USD new, the 480-510 GHS Rockminer R4 used are available for $190 USD and used Rockminer T1’s with 780-840 GHS are being sold for $330 USD. The prices are good for the Rockminer ASICs, however do note that they do not come with a PSU and with a power usage of about 1W per GHS they are already not so adequate for long term mining, unless of course you do not pay the electricity bill. With their hashrate the Rockminer ASICs could be more interesting for people that want to get one for playing with it, not with the idea to use it for mining for profit.

BitMain has listed the upcoming ~500 GHS AntMiner S3 Bitcoin ASIC miner on their website based on the new 28nm BM1382 chips that were recently announced. The AntMiner S3 should start shipping from July 10th with a price set at 0.75 BTC, so you can already pre-order your unit if you are interested. The initial effective hash rate for the S2 was announced to be 504 GHS plus/minus 5% and now it seem that Bitmain has lowered it a bit to 478 GHS, though the unit should be overclockable to 500 GHS or more. The power consumption for the 500 GHS hashrate that was previously announced was 390W on wall and now with the official hashrate lowered a bit the power usage is also a bit lower at 366 Watt.

AntMner S3 Final Specifications:
– Hash Rate: 478 GH/s±5%
– Power Consumption: 366 Watt at the wall
– Power Efficiency: 0.77 J/GH on wall
– Power Supply: 12V DC
– Size: 331 mm x 137 mm x 160 mm
– Fans: Two 14038 fans mounted on both front and back ends.
– Operating Temperature: 0 °C to 35 °C
– Complied with: FCC / CE
– Network Connection: Ethernet

Do note that the BitMain AntMiner S3 ships without a PSU. There are 4 PCI-e connectors for +12V DC input, but it apparently needs only two of them to be connected if you are not going to be overclocking the device, so the other two are required only if you do plan to overclock the device.
