GameMax PSUs Buying Guide and FAQ
This GameMax PSUs 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.
