FSP SFX Pro 450W Power Supply (FSP450-50SAC)

Bottom line: The FSP SFX Pro 450W Power Supply ($79.99 on Amazon as of 2026-10-06): SFX form factor fits Mini-ITX and SFF cases where a standard ATX unit will not; main trade-off: non-modular, so every unused cable stays in an already cramped SFF case.

  • ✓ Free SFX-to-ATX bracket included, so it drops into Micro-ATX and ATX cases too
  • ✓ 80 PLUS Bronze certified efficiency at 450W for budget and office builds
  • ✓ DC-to-DC module design for tighter voltage regulation on the 12V rail
  • ✓ Temperature-controlled sleeve fan spins down when the system runs cool

Cons

  • ✗ 450W ceiling rules out most modern mid-range and high-end GPUs
