Bitmain with Two New 7nm ASic Miners – Antminer S15 and T15

9 Nov

Bitmain has announced its next-generation 7nm miners – Antminer S15 and Antminer T15 and is already taking orders for the new devices with estimated shipping time for the second half of December. Both new Bitcoin ASIC miners have two different operating modes – a high-performance one for maximum hashrate and an energy saving mode that offers better energy efficiency with lower power usage and reduced hashrate. Antminer S15 is available for $1475 USD with a limit of 2 miner per user and Antminer T15 for $913 USD with a limit of 50 miners per user. The new miners do come with a built-in power supply included in the price, but be aware that apparently this PSU is only for 220V input power and also the output voltage is not the standard 12 used previously, so finding an alternative power supply may turn out to be a bit of a challenge.

The Antminer S15 high-performance mode can achieve a hash rate of 28 TH/s with a power efficiency as low as 57 J/TH (1596W); its energy-saving mode can improve power efficiency to 50 J/TH while maintaining a hash rate of 17 TH/s (850W). The Antminer T15 high-performance mode sees a hash rate of 23 TH/s and a power efficiency as low as 67 J/TH (1541W). Its energy-saving mode can improve power efficiency to 60 J/TH while maintaining a hash rate of 20 TH/s (1200W). The new Anminer ASIC miners come with a new high conversion power supply APW8 that has a non-standard 16-18V high-voltage output, so they can effectively reduce the power loss during the power conversion process, helping mining farms save on electricity costs, or so Bitmain claims as a reason to include the new power supply module as a part of the miner. The only problem is that the new power supplies are not designed to operate on 110V power grids and that can present a challenge for some regions that do operate on these.

I don’t think anyone should run an ASIC miner that pull more than 1000W on a 110/120V circuit, it’s not cost effective for the number of circuits you have to run and you need higher gauge wire to support higher amperage draw compared to 220/240V.

Here in canada 120V is standard but it’s dirt cheap to convert a 120V circuit to 240V. That’s a no brainer for me for performance and safety reasons.

Thoses new antminer are interressing but the switch to a PSU that does not output 12V is concerning as you can’t really use any aftermarker PSUs or repurpose old PSUs for other usages…

The power supply is a serious problem here in the US where 3 phase power for crypto mines runs at 208v. Guess I will have to look for miners elsewhere unless they release one that works at 200v.
