XH-M229 desktop computer power adapter board

The XH-M229 Desktop Computer ATX Power Delivery Module splits a standard 24-pin ATX power cable into four different power outputs, each with individual ground and output fuses. At the module’s outputs, there are two binding posts for all four outputs, which can be used to power external devices. There is also an onboard ON/OFF switch that can be used to turn the output on/off at any given time. ATX power module board, the functions include a power indicator light and a main switch for turning on and off the power supply, suitable for developing low-voltage power supplies for physical computing projects (embedded systems).

Product parameters:
– Product name: ATX power board
– Output voltage: Provide 4 sets of output voltages, including 33V, 5V, 12V, and -12V
– Output current: refer to the parameters of the desktop power box (the maximum current limit for each group cannot exceed 20A)
– Number of PINs: 24PINs
– Pin description: standard 24-pin ATX computer power socket, compatible with 20-pin pin socket
– Compatible port: ATX (compatible with some BTX types)
– Hole spacing: 121*41.5MM
– With replaceable glass fuses: Each output channel has replaceable glass fuses and corresponding ground binding posts for easy connection.

The module only supports 24-pin and 20-pin computer power motherboard pin output plugs.

24PIN port:
The main computer supplies power to the main board of the computer. Usually, the ports are used together. If your power supply is a 20PIN port or other ports other than 24PIN, how do you plug in the wire? The socket is inserted from the origin mark on the circuit board. Use Please note.

Voltage description of each terminal:

-12V to GND, GND is positive, -12V is negative, voltage DC12V
+12V to GND, +12V is positive, GND is negative, voltage DC12V
+12V to -12V, +12V is positive, -12 is negative, voltage DC24V
+5V to GND, +5V is positive, GND is negative, voltage DC5V
+3.3V to GND, +3.3V is positive, GND is negative, voltage DC3.3V
The -12V terminal is not recommended to carry a large current load; it just provides a logic potential for the motherboard; usually, the current is about 300MA.
