4.Lift the release latch and slide the power supply about 25 mm (1 inch) toward the front of the system.

5.Continue to apply pressure on the release latch while pulling the power supply towards the front of the computer and rotating the power supply out of the chassis.

See the instruction label on the side of the power supply for additional information.

NOTE: Perform the next step only if you are completely removing the power supply from the chassis.

5.To completely remove the power supply from the chassis:

a.Remove the AGP brace.

b.Remove all full-length expansion cards.

c.Remove the expansion-card guide.

d.Disconnect the DC cables connected to the drives and to the system board.

e.Using a flat-tipped screwdriver, pry out the power supply hinge pin from the chassis foot.

f.While supporting the weight of the power supply, pull the power supply hinge pin completely out to release the power supply from the chassis.

When installing a replacement power supply, remember to rotate and secure the "L" end of the hinge pin into the groove on the chassis foot after installing the hinge pin.
