PC Power Supplies


Asus ROG Loki SFX-L 850W Platinum Power Supply - White

Power supplies play a critical role in your gaming PC and should be a high priority when piecing together your new build. Overclockers UK has a huge selection of power supplies in different wattage ratings and form factors, with some models even sporting features such as RGB! When choosing your new PSU, we’d recommend using an online tool to calculate how much wattage you’ll need during peak load. Our range includes models from industry-leading PSU manufacturers, including Corsair, Kolink, Seasonic, be quiet!, and more, meaning you’re certain to find the perfect power supply for your gaming PC.


EFFICIENCY

A power supply’s efficiency is a measure of how much energy is lost between your wall socket and the power delivered to your PC's components. You’ll often see PSU efficiency listed as an 80 PLUS rating. This certification simply means a given power supply is at least 80% efficient at 50% load.

Power Supply FORM FACTORS Explained

Power supply form factor is what determines a PSU's size and shape. Different form factors, such as ATX, SFX, and TFX, are tailored to fit specific case designs. Choosing the correct form factor is essential for ensuring a power supply unit fits comfortably in your PC case, allowing for efficient cable management and proper airflow. Many PC chassis will be able to accept different power supply form factors. However, the most commonly used PSU size is ATX. If you’re unsure which PSU you need for your specific PC case, you can check the specifications online or in the manual.


MODULAR, SEMI-MODULAR, AND NON-MODULAR

When it comes to choosing a PSU for your gaming PC, you have three choices. Non-modular, semi-modular, and modular. For budget gaming PCs and beginners, a non-modular power supply can be a great choice, thanks to their lower price point and pre-attached cables. Semi-modular power supplies have core cables permanently attached but also feature some detachable cables. Finally, a modular PSU features all the necessary connectors without power cables fixed in place, giving you the freedom to only use those that you need.

What wattage power supply do I need?

When choosing a PSU for your gaming PC, you’ll need to ensure it provides enough wattage for all of your components during their peak load. We suggest using an online tool to calculate how much wattage the components in your PC will need.

What do efficiency and 80 PLUS ratings mean?

Efficiency and 80 PLUS ratings indicate how effectively a PSU converts AC power from your outlet into DC power for your components. The 80 PLUS standard certifies PSUs based on their efficiency levels, with ratings like Bronze, Silver, Gold, and Platinum, representing increasingly better performance and energy savings.

What are PSU form factors?

Power supply form factors determine their size and compatibility with different case designs. Common form factors include ATX, SFX, and TFX, each tailored to fit specific cases. Choosing the right form factor ensures your PSU fits comfortably in your case, promoting efficient cable management and proper airflow.
