Power Supply Fitting for a PC


For those who have never had to open up their own desktop computer, having to replace and fit a new power supply may see a bit daunting at first. In fact, the task is fairly simple. The main challenge is making sure you obtain the correct replacement power supply unit that fits your computer. With that part taken care of, the actual installation process involves basic tools and some patience. Once you've performed it a first time, a power supply replacement will be a simple task in the future. Fortunately, the need does not occur
Instructions
  1. Unplug your computer's power supply. Disconnect the monitor and external peripheral equipment (the keyboard, mouse, printer, modem, etc.). Remove your desktop processor unit (the main computer part) from its sitting place to table top where you work freely. Turn the unit around so the backside is facing you. Use a Phillips screwdriver to unscrew all the chassis bolts keeping the cover on the unit.
  2. Remove the cover and set it aside. Use the compressed air can to clean off the area you are going to work on. Locate the existing power supply unit by the cooling fan on the back of it. Use the screwdriver to remove the power supply's securing frame screws. Carefully pull the old unit free after disconnecting its wires to various computer units. Place the old unit aside or throw it away.
  3. Unpackage your new power supply unit. Remove all the packaging material and unwrap the wires connected to it. Carefully position the new unit in its holding frame in the processor unit. Use the screwdriver again to insert the securing screws holding the supply unit to the processor unit framework
  4. Separate the wiring coming out of the power supply unit. Find the motherboard wire and connect it first. Connect the drive power supply wires second as they match to your hard drives and your CD or DVD drive. Connect your floppy drive wire last if you have a floppy drive. Check that every wire is carefully but firmly connected. Rewrap the unused wires with a small zip-tie and tuck them out of the way.
  5. Reconnect your keyboard and monitor to the back of the processor. Plug the processor into a wall plug and turn it on to test the power supply. Confirm your computer starts up correctly and all the drives work properly. Turn the computer off and disconnect the power again. Replace the chassis cover and secure the chassis screws. Place your processor back in its resting place. Reconnect the power and all your peripherals.
