How to replace the Antminer LS-7R0S14+12 7KW water cooling PSU?

The APW12 LS-7R0S14+12 7KW PSU is designed to work with Antminer S19 series water-cooling boards, featuring multiple aluminum alloy water-cooled radiators, stable voltage operation, and a maximum output power of 7kw. It can help miners cool down quickly, achieve optimal overclocking performance, provide more stable output, and extend the miners' lifespan, making it one of the best switching power supply options for miners with water cooling. Specifically, it is suitable for models such as Antminer S19, S19pro, S19jpro, S19+, S19i, S19j, T19, etc.

This power supply is an essential component for the operation of Hydro miners. If the psu fails, the Antminer cannot operate normally and continuously generate profits, then it may also pose a threat to the internal hardware of the miner. Once a power supply failure is detected, it must be replaced immediately.

Specific parameters:

Input: 380V~; 3W+PE; 50/60Hz; 18A MAX

Maximum Output: 14V-; 460A MAX

12V-; 1A MAX

Maximum Output Power: 7KW

Detailed instructions for quickly replacing the LS-7R0S14+12 water cooling PSU:

1. Disconnect the miner's powering cable, unplug the water inlet and outlet pipes located on the outside of the power supply. Block the water inlet and outlet of the water cooling board to prevent coolant leakage.

2. Remove the control board cover, detach the conductive copper sheets, unplug the corresponding cables, then take out the water-cooled power supply unit.

3. After checking that the new PSU is intact, align it with the chassis position and push it in.

4. Fix the conductive copper sheets connecting the power supply and the hash board with screws, plug in other cables, then tighten the fixing screws of the PSU.

5. Install the control board shell.

6. Finally connect the water pipes to the water inlet and outlet.

7. Power on the miner and the radiator, then check if the miner is operating normally.

Replacing this water cooling power supply, with its strong compatibility, matching capabilities, and excellent performance, provides stable power for the S19 series miners, enabling them to operate with 7KW high power output and achieve overclocking. Choosing a high-quality power supply reduces the failure rate and effectively guarantees stable income for miners.
