PC Power Supply

The computer power supply unit is

located on the left wall of the PC

enclosure.

1) Loosen the bottom terminal

screws and disconnect the

U-shaped wire terminals

(DC Outputs). You may

mark or tape the wires to

facilitate re-assembly to the

correct terminal. The wires

are in sequence from front

to rear as follows:

• +12V – Thick Yellow

• RTN – Double black

• -12V – Green

• -5V – Orange

• RTN – Yellow (thin)

• RTN – Light Red (thin)

• +5V – Red (thick)

• +5V – Vacant

Use a “stubby” Philips screwdriver to loosen terminal screws
