Frequently Asked Questions (FAQs)

1. Is a modular power supply better?

The biggest advantage of modular power supplies is you can remove any cable you don't need. Most users need only four or five cables. This leads to better cable management, better cooling and lower temperatures, which translate to better performance for the rest of your hardware.

2. Are fully modular power supplies worth it?

Generally it is agreed that full modular > semi modular > fixed, but modular PSUs are more expensive. Some unmodular power supplies offer a lot more cables, options, or more wattage for the dollar, but modular units usually have higher quality and the obvious ability to reduce cable clutter.
