ATX Power Supplies Buying Guide and FAQ

This ATX Power Supplies range groups units by this feature. Below are the common questions.

What does modular mean on a power supply?

A modular PSU has this feature. It is a useful feature to look for when matching a unit to a modern build.

Do I need a modular power supply?

It depends on your case: SFX units are for small-form-factor builds, while a normal tower takes a standard ATX unit. Match the feature to your parts and case.

What wattage and rating should I pair with it?

Choose wattage around your graphics card, roughly 650 to 750W for mid-range and 850W and up for high-end, and aim for a reputable 80 Plus Gold unit. That combination suits most gaming PCs.
