Use Your Dell Optiplex Gx150 Motherboard With A New Power Supply

A Dell OptiPlex GX150 workstation computer requires an internal power supply to run. If the power supply fails over time and needs to be replaced, the procedure is fairly easy and can be done by the owner if care is taken to avoid electrical shock. The power supply is a non-standard unit that can be purchased from Dell directly.


1. Purchase a power supply unit that will fit the OptiPlex . The power supply for this desktop is a non-traditional design. It is an elongated, narrow design.

2. Turn off the computer and remove all cables from it.

3. Lay it on its side, and remove the screws holding the cover on the case. Remove the cover and set it aside.

4. Find the DC power cables running from the power supply to the motherboard. It usually looks like a bundle of cables attached to a small plastic connector.

5. Disconnect the connector by squeezing the clip at its base to release the cable.

6. Disconnect the power connectors to the drives in the system also.

7. Remove the four screws holding the power supply to the chassis on the rear. When these are removed, the power supply will be free of the chassis.

8. Install the new power supply in the same spot from where you just removed the old power supply. Install the DC power cable to the motherboard. It will click in place.

9. Reattach the cables to the drives in the system.

10. Secure the four screws back into the power supply and tighten.

11. Close the case cover and replace the screws. Set the computer upright.

12. Attach all devices: keyboard, mouse, monitor and power cable. Turn the device on to verify that the new power supply works.
