Building a compact PC, especially for mini-ITX and small form factor rigs, requires careful selection of components. One of the most critical components is the power supply unit (PSU). In 2026, semi-modular PSUs continue to be popular among enthusiasts and professionals for their balance of flexibility, efficiency, and space-saving design. This article explores the best semi-modular PSUs suited for small rigs in 2026.
Why Choose a Semi-Modular PSU for Small Rigs?
Semi-modular PSUs offer a middle ground between fully modular and non-modular units. They provide detachable cables for essential connections, reducing clutter and improving airflow within small cases. This flexibility makes them ideal for mini-ITX builds where space is limited and cable management is crucial.

- Efficiency: Look for units with 80 Plus Gold or higher certification for energy savings and reduced heat.
- Form Factor: SFX or SFX-L form factors are preferred for small cases.
- Power Output: 450W to 650W is usually sufficient for most mini-ITX builds.
- Cable Management: Detachable cables for essential connections.
- Build Quality: Durable components and reliable protection features.
