SFX Power Supplies

PSUs (Power Supply Units) supply electricity to the components inside your system. It's important to pick a good-quality PSU to ensure a stable supply of power, low noise and not to waste too much electricity.

In this category you'll find a variety of compact SFX PSUs which are designed for small form factor cases. Make sure that your case has the correct mountings for a SFX PSU as there are multiple types of PSU form factor.

Start by checking how many Watts (W for short) your system requires. You can find this information in your component documentation or our buyers guide.

It's also essential to pick a PSU with the right connections for all the components in your system. Choosing a PSU with modular cables will save space inside your system, aiding cooling.

It’s also important to look at efficiency, which can be seen in a PSU’s 80 PLUS rating. More efficient PSUs waste less electricity as well as running quieter and cooler.
