Small form factor power supplies (SFX PSUs) have become increasingly popular among PC builders who seek compact yet powerful systems. These PSUs are essential for mini-ITX builds, home theater PCs, and custom gaming rigs where space is limited but performance cannot be compromised.

What Makes a Good Small Form Factor Power Supply?

Choosing the right SFX power supply involves considering several factors:

  • Wattage: Ensuring sufficient power for your components.
  • Efficiency: Higher efficiency reduces power waste and heat.
  • Build Quality: Durable components and reliable protection features.
  • Connectivity: Adequate cables and connectors for your hardware.
  • Size: Compact dimensions that fit your case.
