Important:
The mainboard’s power supply requirements may vary depending on the manufacturer and
product. Please refer to your mainboard’s operating instructions for detailed specifications and
instructions. If you do not have the necessary level of technical knowledge to install the device,
please arrange for an expert or specialist company to install it.
Removing the old power supply unit
Set the power switch on the power supply unit to off and unplug the computer from the
mains socket. Wait around 20 minutes to allow any residual power to discharge and to allow the
power supply unit to cool down.
Following that, open the computer by unscrewing the left side panel. Now disconnect all
connections between the old power supply unit and the various components such as the
motherboard, the hard drive and graphics card, etc.Then unscrew the screws that are used to
secure the power supply unit to the back of the computer and carefully remove the power
supply unit.
Installing the new power supply unit
You can now slot the new power supply unit into the mount. When doing so, make sure that the
single ventilation grill on the inside of the computer is not blocked so that hot air from inside the
computer can be sucked in and vented to the outside.
After that, tighten the screws on the back of the computer again.
Connecting the power supply unit
You can now start connecting the components to the power supply unit. Never try and plug a
connector into a socket using force as this may result in the power supply unit and hardware
components sustaining damage which is not covered by our warranty.
