With the rise in the price of Bitcoin, like most other cryptocurrencies, they gradually stopped using regular PCs and switched to using special equipment - miners. They are much more powerful and are specifically designed for these purposes. The price, of course, is not the cheapest for such equipment, but it justifies itself.
After all, the more powerful the miner, the more income it brings. Consequently, even the highest cost quickly pays for itself. This can also be said about the Antminer Z15 420ksol miner from pushminer.ru, which is now one of the top sellers.
Hashrate and mining power
We present comparative characteristics in the table.
| Model | Antminer Z15 | Antminer Z11 |
| Hashrate kSol/s | 420 | 135 |
| Power consumption W | 1510 | 1420 |
| Energy efficiency J/kSol | 3.72 | 10.5 |
| Dimensions (L*W*H)mm | 245*132,5*290 | 242*134*302 |
| Weight (net) kg | 5.9 | 5 |
Bitmain Antminer Z15 has three times the hashing speed of the previous model and all other competitors. At the same time, the power consumption of the Z15 compared to the same Antminer Z11 increased by only 5%.
Four fans of the air cooling system protect the device from overheating under high loads. Bitmain Antminer Z15, of course, is quite noisy, like all machines for professional mining, but, on the other hand, it is the most cost-effective ASIC based on the Equihash algorithm.
Review of the Bitmain Antminer Z15 miner
Antminer Z15 is the most powerful model in the line of miners offered today by Bitmain. Antminer equipment is in great demand among retail miners and has proven itself due to its high reliability and operating efficiency.
The Z15 is a relatively new model. It was first introduced in May 2022. This device is designed for mining the ZCash cryptocurrency and a number of other coins (ARRR, ZEN, etc.) using the EquiHash algorithm.
The Z15 inherited the external design from its predecessor Z11, but exceeds it in size (245 * 132.5 * 290 mm), although it weighs almost the same (5.9 kg). There are two cooling fans mounted on the front panel of the unit, each of which consumes 1.65 A. There are no fans on the rear panel.
The miner is supplied with a proprietary Bitmain APW7 power supply.
The hashing speed declared by the manufacturer is 420 ksol/s, which is 20 ksol/s more than that of younger models. In practice, this parameter can fluctuate in the range of 410-430 ksol/s. Energy consumption is 1510 W, which is also slightly more than less powerful models. However, the Z15's energy efficiency is far ahead of its predecessors, with an incredible 3.6 J/ksol.
The computing power of the Z15 is provided by three hash cards, each of which has three VM1746AA processors. Each processor is equipped with a separate massive heatsink with a copper plate and two thermal tubes. This cooling system ensures effective heat removal from the chip and prevents the device from overheating even during intensive use in not very favorable external conditions. The operating temperature range declared by the manufacturer is from 0 to 40 degrees Celsius.
The control interface is inherited from previous models. The console has a simple look and is intuitive. Only one standard mode is offered, which does not provide advanced overclocking options.
Overall, the Z15 is a great option for miners who want to diversify their coin mining and not just rely on Bitcoin or Ethereum. It consumes less energy than devices using the SHA-256 algorithm, but is still capable of generating decent income. The estimated payback period is about 250 days. This is almost half as much as, for example, the Z11 model.

According to the exchange rate as of 05/29/2020 and at a socket price of 0.06 $/kWh, the antminer z15 brings the greatest income in 24 hours by mining the following cryptocoins:
- Pirate Chain (ARRR) — 18.53$;
- Horizen (ZEN) — 18.28$;
- Zcash (ZEC) - 16.96$;
- Hush (HUSH) — 16.36$.
Data taken from the WhatToMine mining calculator website, link https://whattomine.com/miners/119-bitmain-antminer-z15?cost=0.06 .
Let's now calculate the approximate payback period for the investment. On the manufacturer's website https://m.bitmain.com/product/000202005181646406623qW7sVBE0677 this model costs $1,565. If the current profit of this Bitmain mining machine remains more or less stable and there are no malfunctions, then the antminer z15 will begin to generate net profit in just 83 days. This is simply an excellent result.
Cryptocurrencies are volatile and tomorrow the amount of profit may change (but not necessarily downward). In addition, the top digital coin on the Equihash algorithm, Zcash, has been showing a price strengthening trend over the past month.
This means that, at such a cost, the owner of a new ASIC z15 will recoup his money invested in the device in 3-4 months (and maybe faster). But, this is the selling price from a warehouse in China, if you take into account all the overhead costs, the payback period will approximately double. Wholesalers have long appreciated their benefits and on the official Bitmain website the first batch of Antminer Z15 has already been sold out. How to be?

The best silent ASIC for home with CBO installation - Bitmain Antminer Z15 hydro
Bitmain Antminer Z15 is an efficient miner that has a high hashrate and a short payback period. The ASIC consumes only 1650 watts, making it one of the most energy efficient ASICs in the world as of November 2022.
ASIC has not changed traditions for the third year and is still in the same Z9 / Z11 case, which also makes it one of the most compact miners on the market.
The main advantage of the Z15 is its hashing speed, which is several times higher than the previous model from Bitmain and all competitors on the market. Energy consumption has increased by several percent, compared to the Z11 model by 5%.
The cooling system is represented by 2 fans, which prevent overheating during prolonged operation of the equipment. Today he is considered one of the most profitable miners on the market, which generates income on the Equihash algorithm.
Payback periods and available coins
When calculating the payback, it is necessary to take into account the volatility of the mined cryptocurrency, which can change from day to day. The most popular coin on the Equihash algorithm is Zcash, which has been pleased with the strengthening of its value and capitalization over the past few months. Using ASIC Bitmain you will mine the following coins: Zcash (Zec), Pirate Chain (ARRR), Comodo (KMD), Hush (HUSH) and Horizen (ZEN).
At the time of calculation, the owner of the new miner will be able to recoup the invested funds in 5-7 months. The payback period increases depending on the cost of Asik, which is available at different prices on different platforms. By ordering the device directly from the warehouse, you save significantly.
Advantages of CBO for Bitmain Antminer Z15
At the moment, bathtubs with immersion cooling are the most popular, so we invite you to compare this option with our AQUA SVO.
First, you need to take into account the cost, since every miner pays his attention to this indicator first, and for many it is decisive. The price of a bathroom is about 30% of the cost of a new ASIC from Bitmain or Insilicon. In this case, you also need to take into account the cost of each liter of mineral oil. It is necessary to choose only high-quality oil so as not to cause damage to the circuit boards of your equipment. At the same time, electricity costs increase by 25% of the amount of electricity consumed by your miners. When you calculate all the costs from scratch, you get the feeling that the Asics, along with the bathroom, will pay for themselves forever. Using a bathroom is suitable for large farms when it comes to reducing energy costs, but this method is definitely not suitable for home use.
What do we offer? The ideal solution for every miner at a fixed price! At the same time, you will benefit from connecting a large number of ASICs to the SVO. The advantage of using our system is access to the device at any time. You can repair the control board, power supply and other components if necessary. When using a bath, you must wait at least 3 days until the device is completely dry. Therefore, it will not be possible to carry out an urgent replacement.

Pros and cons of ASIC
Bitmain Antminer Z15 is an efficient device with a high hashrate and a very acceptable payback period. Its disadvantage is the high noise level.
If you have 167,325 rubles to buy an ASIC, you still won’t be able to place it in a residential building. Owners of private houses can somehow find a way out, but a resident of a high-rise building needs to carry the installation of a mining hotel.
