Install A New Power Supply In An Atx Case

Upgrading Your PC

Installing a new power supply in your computer is one way to boost performance and possibly solve problems that can arise from unstable power distribution. The ATX form factor power supply fits into cases that are specifically made for the ATX. The ATX is a second-generation form factor based on the AT design. Equipped with multiple cables to connect your hard drives, motherboard and other peripherals, the ATX is a popular choice with computer enthusiasts.


1. Power down your computer and unplug the black power cord. Unscrew the thumb screws or fastening screws on the case with a Phillips screwdriver and open the case.

2. Unscrew the mounting screws holding the old power supply in place. Sketch a layout of the cables and what they connect to inside your computer. The more detailed your sketch, the easier it will be to reconnect the new power supply's cables.

3. Remove the old power supply and detach the cables from each of its connections.

4. Place the new power supply inside the case in the old power supply's location. Secure the new power supply with mounting screws and the Phillips screwdriver.

5. Connect the cables to the correct connections according to the sketch you drew in Step 2. Seat the connections securely. You will have cables for your motherboard, hard drive, CD-ROM drive and other components of your system. Tuck the extra cables you don't have a need for at this time neatly into the case of your computer. If you add additional hard drives or other components, you will need these cables.

6. Secure the case with the screws you took off when you opened it. Plug in the power cable and power up your computer. Your new power supply is now supplying the power to your computer.
