Jinbei Miner BOX Series——Opening a new experience of low-power and silent mining at home

May of previous years is always a time for miners to celebrate, because the arrival of the flood season usually means lower mining costs. However, May of 2021 is a bit turbulent for miners. After experiencing the 519 crypto market waterfall and the 521 power restriction order, new and old miners are confused. Mining farms have gradually reduced their loads, and many industrial parks have also started power outages for rectification. Major mining machine manufacturers have stopped releasing new machines. At this time, the mining website has received a new machine evaluation request from Jinbei Mining Machine. The editor couldn't help but tremble when he heard it. How much confidence does it have to go against the trend at this time?

After getting the prototype, the editor was suddenly enlightened. As the originator of home mining machines, the three new Box series silent mining machines launched by Jinbei hit the pain points of all miners. In view of the fact that a large number of high-power ASIC mining machines in the current mining field cannot be powered on and run, the computing power of the POW mining coin network has dropped significantly. At this time, home mining machines that can continue to mine without being affected by policies are bound to be eye-catching.

Currently, only KDA-BOX is available for public sale in the Jinbei BOX series, so I will start with it. Let's take a look at the performance parameters: power consumption 205W (+-5%), computing power 1600G (+-5%), official website price: ￥10480 yuan.

It is worth mentioning that the Jinbei BOX series does not rely on a computer except for the initial configuration, and can run independently.

About Static Payback Period

At the current difficulty, the 24-hour income of this KDA-BOX is about 9 KDA. The electricity fee is temporarily calculated at 0.4 yuan per kWh, and the daily electricity fee is 1.97 yuan. Without considering the rebound of the currency price, the static payback period is about 373 days. Its power consumption is about the same as that of a TV set that plays all day, and the electricity bill is stress-free. If you regard it as a household appliance or decoration, you will be particularly relieved, because when you watch TV or turn on the chandelier in the living room, you never and will never calculate its payback period.

Appearance and structure

KDA-BOX has an ultra-mini size that can be held in one hand. It adopts a new heat dissipation structure design, optimizes the airflow direction between modules, connects the chip with the heat sink through thermal conductive silicone, quickly and efficiently sends out the heat generated by the whole machine, effectively dissipates heat, and is very suitable for home users.

Bare metal size: 175MM*150MM*84MM

The Jinbei machine still uses an aluminum alloy body, with a simple and elegant appearance, but it is small but complete. However, this mining machine adopts a separate design of mining machine and power supply. The mining machine power supply adopts a 6PIN interface, which is the same as the desktop graphics card power supply, so you can equip it with a suitable power supply. If you mine multiple machines together, you can also buy the official one-to-four power supply, which is very convenient for home users.

This machine is really compact, and it’s easy to imagine by looking at the comparison picture below with ordinary tissue paper bags.

It can be held in one hand, it is small and light, so it is also very convenient to disassemble. Compared with previous machines, this machine does not even require a technician to disassemble, the editor can do it in minutes.

The connection method between the hash board and the main board is eye-catching. It has to be said that Jinbei has mastered the simplification of the internal structure of the mining machine.

Group photo of all parts

The simple design reduces the disassembly and assembly workload for the editor a lot, because there is no external integrated power supply. Compared with the previous group photos of mining machine components, the group photo of KDA-BOX components is a bit thin.

Performance Test

Next, assemble it, turn on the machine and configure the mining pool. This step is the same as other mining machines, so I will not go into details.

After running for 24 hours, we look at the average computing power of the mining machine and the mining pool. The average computing power of the mining machine is 1597GH/S, and the average computing power of the mining pool is 1583.54GH/S, which is basically consistent with the official data.

Let’s take a look at the actual operating environment data. The actual operating power consumption is 205W, which is exactly the same as the official website parameters.

Air inlet temperature 31.8℃

Air outlet temperature: 42.3℃

Noise measurement: the ambient noise in our studio is 48db

In this environment, the operating noise of this mining machine is 55.7db, which is basically the same as the noise in a normal working environment. You can imagine the volume of a household electric fan by yourself. Placing it at home does not affect your life at all. In addition, Jinbei will release a new noise reduction firmware later to further reduce the fan speed to achieve a better noise reduction effect.

Data comparison

Summary

Jinbei KAD-BOX mining machine is the first BOX series small household mining machine publicly released by Jinbei this year. It is easy to operate, quiet and lightweight, and has extremely low power consumption on the wall. In the current market environment where chips and energy are in short supply, it opens another door for miners to continue mining. Through the unboxing and actual test data, everyone can see that the performance of this machine is still very good. The shortcomings and deficiencies are still: the total output is limited, first come first served!
