Semi-Modular PSUs (27)

If you want to improve your computer performance, it's worth looking into a new power supply unit (PSU) that's capable of supporting your various other components properly (such as more advanced CPUs and graphics cards). Semi-modular PSUs come with only the essential components connected and ready to go. This means you have some level of customisation available to you if you want to further adapt your computer's PSU.


Modular PSUs would give you complete customisation control, whereas non-modular are fully set up and ready to go with no customisation required. Browse the full range below!
