Remark:

-P8 and P9 connectors MUST be plugged in so that the black wires are side by side (together in the center).

-Some systems without motherboards do not require the P8 & P9 connectors which can be left unused.

-Some systems do not require the On/Off switch which can just be left switched ON and tied up safely inside the machine.

-Supplied with a big latching switch suitable for most AT systems. The switch is removable and can be replaced by another one (terminal block size: 9x0.6mm). Check the diagram on the PSU for the correct wire connection. A wrong connection will damage the PSU.

-Some AT PSUs come with an additional 6-pin flat connector labeled P10. (With three black wires and three +3.3V orange wires or three +5V red wires). Select this optional connector is required.

This replacement AT PSU combines authentic legacy compatibility with modern reliability standards, making it the ideal power solution for maintaining and restoring classic computer systems.
