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 100V.
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 100V
with 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
repeatedly
stops and
starts 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 that the power and ambient temperatures
follow 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.
6.
Precautions for Use
1. Before using the PSU, please ensure that the voltage and power outputs are
compatible with your equipment.
2. 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.
3. Make sure that the metal cover for the PSU with on/off switch is properly grounded.
Improper grounding is dangerous.
