Fully Modular PSUs (36 products)

Upgrading your computer's PSU (power supply unit) is a great way to make sure it can support more advanced components like graphics cards and CPUs.


PSUs vary by how customisable they are - fully modular PSUs don't have any prescribed attachments, giving you complete control over their set up. If you want to have a few customisation options, semi-modular PSUs are available, and if you'd prefer a PSU that's completely set up and ready to go, non-modular options are available.


Take a look at the full range below, and don't hesitate to contact us if you need any assistance.
