FAQ

A semi modular PSU (Power Supply Unit) is a type of computer power supply where some of the cables are permanently attached, while others can be added or removed as needed. This design helps reduce cable clutter and improves airflow inside your PC case.

Semi modular PSUs allow you to use only the cables you need, leading to a cleaner build and easier cable management compared to non-modular PSUs, which have all cables permanently attached.

On most semi modular PSUs, the essential cables like the 24-pin motherboard and 8-pin CPU connectors are fixed, while peripheral cables such as SATA, Molex, and PCIe connectors are modular and can be added as needed.

Semi modular PSUs are generally compatible with most PC cases that support standard ATX power supplies. Always check your case’s specifications for PSU size and clearance requirements.

Yes, upgrading from a non-modular to a semi modular PSU is straightforward. Simply disconnect your old PSU, remove it, and install the new semi modular unit, connecting only the necessary cables for your components.
