Switching On/Off Remotely
The PSU turns on automatically by plugging it into the mains. However, it also has a 3-pin port which can be used to remotely power the PSU on and off.

Remote On/Off Method 1: Use the physical power switch to control ON/OFF and GND lines, closing the circuit turns the machine on, and breaking the circuit turns the machine off.
Remote On/Off Method 2: 5V sb PSU supports an external MCU, which controls a transistor or MOSFET to manage the ON/OFF pins to switch the PSU ON/OFF remotely. The PSU will turn on once power is provided to the 5V sb pin.

Trouble Shooting & FAQ
| # | Issue | Reason | Troubleshooting |
| 1
| Fan won’t run, and no 12V output
| AC Input is abnormal
| 1. Make sure the AC input wire has a good connection and the plugs are connected firmly 2. Make sure the mains power is working well and its voltage is above 205V. |
| 2 | The fan is running, but there is no 12V output. | 1. Voltage in your power system is lower than required 2. PSU is in protection mode | 1. Please check whether the voltage is above 205V with a multimeter to make sure the PSU can switch on correctly. 2. Check whether there is a short circuit output or overload that is causing the PSU to enter a locked status. After removing the problem, the PSU should power up. |
| 3
| After a few minutes, the PSU stops working, starts working, stops working, and keeps cycling. | PSU is in over-heat protection | 1. Check whether the fan is working 2. Check whether the fan’s vent is being blocked 3. Check whether there is a dust buildup inside the PSU due to prolonged use. Do NOT remove the PSU’s cover unless trained to do so. 4. Check the power and ambient temperatures following the Load/Temperature graph |
| 4 | Output is normal, but the fan is not working. | Fan is broken | 1. Check that the fan is clear of blockages or buildup 2. Fan is broken and needs to be replaced. |
| 5 | The PSU suddenly has no output and can’t be started again. | The PSU is in over-current protection. | Check whether the load current has exceeded the built-in overcurrent protection limit. The protection automatically triggers when the load current exceeds the limit to protect against damage to the PSU and the miner. |
Precautions for Use
- Before using the PSU, please ensure that the voltage and power outputs are compatible with your equipment.
- Please ensure that the PSU appears to be in good shape and has not suffered damage in transit. If the exterior of the PSU appears damaged, do not use it.
- Make sure that the metal cover for the PSU with the on/off switch is properly grounded.
Improper grounding is dangerous. - The PSU must be installed in such a way that it receives good, unobstructed airflow.
Under no circumstances should the PSU be installed in an enclosed place. - When installing the PSU, please double-check that the output polarities are the correct way round and that the screws are fastened securely in place.
- Do not attempt maintenance on any wiring while the PSU is powered up from the mains.
- Running the PSU at <80% load or below can greatly prolong the life of the PSU. Usually, for every 10ºC above the rated amount, the life of the PSU is cut in half.
