Innosilicon has put up for pre-order their new A4+ LTCMaster Scrypt ASIC that should be capable of delivering 620 MHS hashrate with 750W ot power usage according to the official information. This is an update from last year’s Innosilicon A4 Dominator Scrypt ASIC whih was capable of only about 280 MHS and had higher power usage, so a nice improvement for sure. The new Innosilicon A4+ LTCMaster is available for pre-order at a price of $3200 USD (60.355 LTC, 0.631415 BTC) with delivery scheduled for November 30th to December 10th for the current batch. The price is only for the miner with a minimum order quantity of 3 devices and Innosilicon also has offers available with a 1050W 110V PSU or 1600W 220V PSU, depending on the region you live in and the electric network you use. Payments can be made via LTC, BTC or Bank Transfer, there is 6 months warranty and shipping is only with DHL.

INNOSILICON A4+ LTCMaster Specifications:

– Hashrate: 620 Mh/s (+-8% performance, can be over-clocked at user’s risk)
– Power Consumption: 750W (+/-8%, normal mode, at the wall, with 93% efficiency PSU, 25°C temperature )
– ASIC chips: 288 pcs
– Size: (L)350mm*(W)125mm*(H)155mm
– Gross weight: net weight 3.83 KG (without PSU)
– Required rated PSU: 1000W or above, 8 * PCI-E 6-Pin
– Power supply connection: 2 PCIE port per power board (4 boards)
– Cooling: air-cooled with 2 fans
– Internet connection: Ethernet

If you remember a while ago we have talked about the 550 MHS BW-L21 Litecoin (Scrypt) ASIC Miner as an interesting alternative to Bitmain’s AntMiner L3+ Scrypt ASICs. Unfortunately back then these were hard to order as there was a minimum order quantity of 100 units and not an easy and straightforward way to order them. This is apparently about to change as the manufacturer of the devices Biwang Electronic Commerce Co. (BW) has appointed the Australian company Block Assets Limited trading as HyperBit as their Worldwide Retail Distributor for the L21 ASIC miner. So finally some competition for BitMain in the home mining segment and more options for the small miners to get back into the Litecoin mining…

You can currently order the 550 MHS BW-L21 Litecoin ASIC miner from HyperBit at a price of $2690 USD in single unit quantities and get it delivered worldwide with a shipping set to start on 30th of November for the current batch of miners. The L21 is apparently the current leader in terms of performance Litecoin Application Specific Integrated Circuit (ASIC) miner on the market with 550 MHS hashrate and with just 900W of power usage. It is not clear what the situation with the power supply is at this point however, is there one included (no mention), but a PSU does appear on one of the product photos. Most likely you would need to buy the PSU separately, one that does provide at least 1000W of power and comes equipped with at least 6x 6-pin PCI-E power connectors. Do note that all orders are being shipped directly from the manufacturers location – Shenzhen, China.

BW-L21 Scrypt ASIC Specifications:
– Hash rate: 550MH/s (+- 10%)
– Power consumption: 900W (+- 10%)
– Cooling: 2pcs @ 3000 RPM
– Dimensions: 329mm * 127mm * 159mm
– Network connection: Ethernet
– Technology: 28nm ASIC chips
– ASIC chips quantity: 144 chips
– Operating temperature: 0 to 40 Degree Celsius
– Warranty: 6 months
– Weight: 4.8kg

We have been keeping track on the development of the new Innosilicon A4 Dominator Scrypt ASIC miners since the initial announcement back in November last year and it is time for another update. It seems that Innosilicon is starting to take pre-orders for the final ASIC miners with shipping expected to start in September and there is already a thread on Bitcointalk about a group pre-order that you might want to check out if interested. In the past we have tested the previous generation of Innosilicon A2 Scrypt ASIC miners in the form of the 86 MHS A2BOX Innosilicon A2 Scrypt ASIC Miner that was consuming about 1000 Watts of power, so we can see what the development is and how good actually the new generation is going to be. A solid first generation Scrypt ASIC miner that was built well and performed really good when it was released with the only drawback being the very high initial price of the device, so we were anticipating another good solid product with much better specs when the first A4 details surfaced.

The initial announcement from last year claimed that the A4 Dominator is so efficient that it should be able to deliver about 850 MHS for Scrypt mining with 1020W of power usage. This was really impressive number and really caught our attention, especially considering that the first generation A2 Terminator miners were able to achieve just about 1/10 of that hashrate with the same power usage. A little bit later, in March this year, there was an update on the power usage and efficiency of the new A4 ASIC chips that has significantly lowered the initial numbers – down to 400 MHS from 850 MHS per kilowatt of power. Although the expected performance was lowered more than half it was still a pretty impressive number, but unfortunately this was not the final change and now we have a new number available. Apparently the final product will only be capable of about 260 MHs per 1 KW of power and be available for about $1800 USD without shipping and with power supply not included in the price. While the final performance per KW of power usage is not that bad either, we are not as excited as we were with the initial announcement or the March update. At 260 MHS per 1000 Watts things aren’t that bad, but with these specs we are not going to be pre-ordering one of these miners for sure. Maybe we are going to try to get one unit to test when they come out if it is not a pain in the ass to secure a single unit order.
