Don't underestimate the importance of your PC's power supply. It serves as the cornerstone for a low-maintenance and highly reliable computer. Unfortunately, many pre-built desktops come with cheap power supplies that may fail after a couple of years. Additionally, upgrading your graphics card can push your power supply to its limits. If you own a Hewlett-Packard 5188 power supply and need to replace it, don't worry. This article will guide you through the process of safely removing your old power supply and installing a new one.
How to Remove Your Old PC Power Supply
The first step is to gather your tools, which will likely only require a pair of gloves and a Phillips head screwdriver. Once you have your tools ready, follow these steps:
- Unplug all the cables connected to your computer from the wall.
- If your power supply unit (PSU) has a power switch on the rear of your PC, flip it to the off position.
- Remove the side panel of your case to access the PSU.
- Disconnect all the power connectors that lead from the power supply to the different components in your computer. Take pictures of the cable connections to use as a reference when plugging in the cables on your new power supply.

- Remove the 24-pin power cable connected to the motherboard along its mid-line on the left side.
