S19pro water cooling power consumption comparison test

As the largest computing power product mass-produced in the air-cooling era, Ant S19pro, with 110T computing power, 3250 watts of power consumption, and an energy efficiency ratio of 29.5w/t, stands out from the crowd. If there is any product that ignores the bull and bear markets, in the air-cooling era, S19pro is the only choice.

In the last test, we completed the evolution of S19pro from air cooling to water cooling, and achieved the stable computing power of 180T for water-cooled products. However, in the current chaotic era, we need not only a certain high computing power product, but also more choices for miners according to market fluctuations. We can get better returns and stronger security margins in different periods and different market conditions.

Therefore, today we will optimize the computing power from 110 segments to 180, and select 3-4 computing power indicators that are most friendly to miners for the final productization of S19pro water cooling based on different computing power indicators, power consumption, and machine power consumption ratio.

In the future, in the era of water-cooled ultra-large computing power, we hope that miners can choose what computing power consumption indicators to adopt based on load, electricity costs, bull and bear markets, and fight for a long time without shutting down.

The key knowledge points of this test are as follows:

The purpose of the 7000W water-cooled power supply: When choosing different computing powers, the actual power consumption of the power supply is different. The custom-developed 7000W power supply is the maximum output indicator.

The reason for the power consumption of various hashrate data: We need to test the most stable chip frequency and hashrate board power consumption, and finally select a few standards and fix them as options. Miners only need to select the system.

1. Test name: S19pro water cooling performance experiment

2. Test purpose: After completing the water cooling upgrade, the actual power consumption under different computing power conditions.

3. Test environment: air-cooled S19pro, water-cooled tower, water-cooled upgrade accessories, ant pool system

4. Test steps:

a) Upgrade air-cooled machine to water-cooled

b) Data testing under different computing power

Let's first give the data, the power consumption comparison under different computing power conditions:

Based on the test results, it is expected that by later changing the water-cooled power supply to a three-phase aviation head and improving the output circuit copper bar, it is expected that the power conversion can be optimized by 2-3% and the overall energy efficiency ratio can be improved.

It has also been verified that after removing the fan and heat sink of the original mining machine and improving it to a water-cooled plate for heat dissipation, the power consumption of the mining machine has decreased and the energy efficiency ratio has improved.

Let's review the whole process of this water cooling upgrade.

1. We prepare a second-hand S19pro 110T air-cooled mining machine

2. Remove the case, fan, and hashboard

3. Remove the air-cooled heat sink

4. Cleaning, dust removal and cleaning of hashboard

5. Unboxing our water cooling upgrade kit

6. Silicone grease on the hash board chip

7. Install water cooling radiator

8. The water cooling plates of the three computing boards have been arranged, and the water pipe interfaces are connected.

9. Connect the hashboard and place it back in the chassis

10. Replace the water-cooled power supply

11. Connect water cooling tower

Because there are many data samples in this test, we selected three more representative ones:

Mode 1 (60% computing power increase):

Hashrate: 178.4T

Power consumption: 6561w

Chip temperature: 60 degrees

Test duration: 15 minutes

Energy efficiency ratio: 36.78w/t

Computing power increased: 68.4T

Improve computing power efficiency ratio: 48.5w/t

The test time of this mode is relatively short. Firstly, there are too many test samples this time. This water-cooled power supply is our first generation product, and we need to make some adjustments to the power supply layout and output. In order to ensure continuous testing of ultra-large current, the test time is relatively short. The mass production standard 7000w power supply in August will be tested according to the industrial finished product plan.

Therefore, the chip temperature under this scheme is only a short-term value. The normal chip temperature, in this mode, should be around 70 degrees.

Mode 2 (30% computing power increase):

Hashrate: 144.36T

Power consumption: 4496w

Chip temperature: 53-57 degrees

Test duration: 62 minutes

Energy efficiency ratio: 31.14w/t

Computing power increased: 34.36T

Improved computing power efficiency ratio: 36.26w/t

Mode 3 (15% computing power increase):

Hashrate: 127.58T

Power consumption: 3678w

Chip temperature: 50-52 degrees

Test duration: 62 minutes

Energy efficiency ratio: 28.81w/t

Computing power increased: 17.58T

Improved computing power efficiency ratio: 24.23w/t

Three (or more) modes are controlled by miners themselves, and they can freely choose according to the energy point electricity price, currency price, and mood. All modes can be selected with one click in the background, without manual changes for a single machine, which greatly improves work efficiency.

The shortcomings of this test:

In order to ensure fast testing, the first generation of water-cooled power supply has a poor appearance and has not yet adopted aviation head input voltage. Therefore, the power conversion of the first product still has room for improvement. It is expected that the product will be improved in August.

Copper bars are used as water-cooled power sources to output electricity to the mining machine, replacing the previous wire output and solving the output problem of large voltage levels. However, the choice of material, weight, and size will still have a lot of room for optimization in conductive output.

Therefore, to solve these two problems, the water-cooled S19pro product should have the same or similar power consumption ratio as the original air-cooled S19pro while increasing computing power by 30%.

We will solve the above problems in August and make the best transition from air cooling to water cooling.

In addition to providing the industry with technical upgrade solutions from air cooling to water cooling for the S19 series, we will also launch water cooling infrastructure solutions for all miners around the world.

We provide you with a one-stop water cooling solution. Please follow Luban, see the future, and move towards the future together.
