What is a PSU?

A PSU, or Power Supply Unit, is an essential component of a computer system. It is responsible for converting alternating current (AC) power from the wall outlet into direct current (DC) power that is required by the computer’s internal components. The PSU supplies power to the motherboard, CPU, graphics card, drives, and other peripherals.

PSUs come in different wattages and form factors, allowing users to choose the one that meets their system’s power requirements. They are typically mounted inside the computer case and connected to the motherboard and other components through a series of cables.

A PSU plays a critical role in ensuring the stability and reliability of your computer system. It protects the internal components from power fluctuations, voltage spikes, and provides a steady flow of power. In the context of liquid cooling systems, the PSU is responsible for powering the pump and fans that circulate the coolant through the loop, maintaining optimal temperatures for the components.

PSUs are equipped with various safety features, including overvoltage protection (OVP), undervoltage protection (UVP), overcurrent protection (OCP), and short circuit protection (SCP). These measures are in place to safeguard the components from any electrical issues that may arise.

Understanding the basic functionality and components of a PSU is crucial when it comes to jumping it to drain a water loop. By bypassing the motherboard and directly powering the necessary components, we can ensure that the water loop is drained properly, without any damage to the system.

Why do you need to jump a PSU?

When it comes to custom liquid cooling systems, draining the water loop is a necessary step for routine maintenance and troubleshooting. Jumping a PSU is required to facilitate the draining process and ensure the water loop is properly emptied.

Here are some reasons why you need to jump a PSU:

• Powering the pump: The pump in a liquid cooling system is responsible for circulating the coolant throughout the loop. By jumping the PSU, you can provide power directly to the pump, allowing it to run and facilitate the draining process.
• Activating the fans: The fans in the system play a crucial role in dissipating heat from the components. When jumping the PSU, the fans will also receive power, ensuring proper airflow and aiding in the cooling process during the draining procedure.
• Removing trapped air: Draining a water loop requires the removal of any trapped air bubbles. By running the pump and fans through the jumped PSU, the circulation created helps in bringing the air bubbles to a location where they can be easily purged from the system.
• Preventing damage to the PSU: Draining the loop without jumping the PSU can cause strain on the power supply unit. The PSU is designed to power the entire system, and without it being engaged properly, it can lead to power surges or improper functionality.

Jumping a PSU allows you to have control over the power supply and ensures that the components involved in the draining process are receiving the necessary power. It enables you to safely drain the water loop without the risk of damaging the PSU or other components.

By following the step-by-step guide provided in the next section, you will be able to jump your PSU effectively and efficiently, making the draining process a breeze.
