Whatsminer P463B P663B oil-immersed cooling power supply is a high-efficiency and reliable hash rate PSU designed for M56 M66 series miners. It features three-phase AC input 320-528VAC/16A, has a main output capacity of up to 4800W, and uses an advanced liquid cooling system to ensure an efficiency of up to 96% at full load output. Additionally, its built-in undervoltage, overvoltage, overcurrent, short circuit, and overtemperature protection provide comprehensive power protection for the miners' operations.
When miners operate under high load and high temperature for a long time, it may lead to power supply failures, resulting in the miners unable to start normally or even damaging other internal components. To ensure the continuous efficient operation of the machines, once the power supply fails, it must be replaced promptly to ensure normal mining revenue.
The specific steps for replacing the Whatsminer P463B P663B power supply are as follows:
1. After removing the protective cover and the fixing screws on the side of the chassis, carefully remove the cover.
2. Open the protection cover, unplug the power cord and other cables.
3. Remove the fixing screws of the power bridge on both sides, then take it off.
4. Gently pull up the handles on both sides of the power supply.
5. Buckle the PSU buckle, lift it up with both hands to remove the power supply from the case.
6. After confirming that the new PSU is in good condition, align it with the slot, gently push it in, ensuring it's fully inserted.
7. Align the power bridge on both sides of the PSU with the screw holes, then tighten the screws with an electric screwdriver.
8. Insert all cables, next install the protective cover.
9. Tighten the screws of the protective cover first and others on the side of the chassis.
10. Power on the miner to check if it can operate normally.
By following the above steps, we can replace the "heart" for the M56 M66 miner, providing efficient powering for its long-term high-load operation. The stable operation of the machine is the key to obtaining continuous revenue. So we must regularly check the status of the miner and replace new spare parts in time when necessary. This can not only reduce potential losses caused by component failures, but also ensure that the miner operates in the best condition, maximizing our mining revenue.
