Mean Well RSP-320-5 AC-DC Switching Enclosed Power Supply PFC
Bottom line: The Mean Well RSP-320-5 AC-DC Switching Enclosed Power Supply PFC ($48.99 on Amazon as of 2026-10-07): 300W of 5V rail at a full 60A, enough for large LED matrix and arcade builds; main trade-off: built-in DC fan means audible airflow noise, a poor fit for silent living-room cabinets.

Pros & Cons
Pros
- ✓ 300W of 5V rail at a full 60A, enough for large LED matrix and arcade builds
- ✓ Active PFC holds pf above 0.95, easing draw on shared workshop circuits
- ✓ Universal 88-264 VAC input runs on any mains without a voltage selector switch
- ✓ Rated up to 85 percent efficiency, so less heat dumped inside the enclosure
- ✓ 3-year warranty plus UL, cULus, TUV, CB and CE approvals on the RSP-320 family
Cons
- ✗ Built-in DC fan means audible airflow noise, a poor fit for silent living-room cabinets
- ✗ 1U 30mm chassis is bare enclosed metal with no case or cord included
- ✗ Single 5V output only, so 12V accessories need a separate supply
- ✗ Screw-terminal wiring assumes comfort with mains AC, not a plug-and-play brick
