How to Upgrade My Computer'S Power Supply
- 1). Shut down the computer and unplug the power cord from the back of the tower.
- 2). Unplug any peripheral cables and lay the tower on its side.
- 3). Remove the side access panel, being careful not to drop the retaining screws into the tower.
- 4). Attach the alligator clip of your anti-static wrist band to the metal tower frame and the hook and loop strap to your wrist.
- 5). Disconnect any connections to the power supply.
- 6). Remove the four screws that connect the power supply to the tower frame and carefully remove it from the case.
- 7). Check the listed wattage rating and purchase a power supply that is rated at least that highly. If you are also replacing your video card, check the video card specifications regarding the minimum power-supply rating required. Having a power supply with a higher rating is fine, but one with too low of a wattage could cause system instability.
- 8). Carefully insert the new power supply into the case and reattach the four connecting screws.
- 9). Reattach the internal peripheral power cables, making sure that you don’t leave any unplugged.
