To remove the system power supply, follow these steps:
1. Disconnect the AC power cable from the AC power connector on the
back of the power supply.
2. Disconnect the DC power cables from the system board (see
Figure 4-14), the externally accessible drives, and the hard-disk drives
(see Figure 4-7).
Be sure to record the connector number and plug location for each power
cable.
3. Remove the four power-supply mounting screws.
4. Slide the power supply forward about an inch to clear the retaining
tabs; then lift it out of the computer.
When you reinstall the power supply, be sure the slots on the bottom of the
power supply engage the retaining tabs on the computer chassis.
