How to Power

Important Note: Please use high quality power adapter, the low quality PSU may damage the X885 board and not recognized the HDD.

Warning about power supply:

  1. Don't use that adjustable voltage power supply.
  2. Don't use the same power supply used on LED strips.

The above two are absolute garbage power supply, can not be used!!!
