For system builders assembling a dependable office PC or a budget gaming rig, the M.RED DU-550B delivers 550 watts of continuous power with 80 PLUS Bronze efficiency. It handles mainstream graphics cards and multi-drive setups without breaking a sweat.

Key specifications

  • 550 W total power output
  • 80 PLUS Bronze certification
  • ATX form factor, non-modular cabling
  • 120 mm cooling fan
  • Active PFC with OVP, OPP, SCP protection
  • Connectors: 1x 20+4 pin ATX, 1x 4+4 pin EPS, 2x 6+2 pin PCIe, 4x SATA, 2x Molex
  • Input: 200-240 V AC, 50/60 Hz
  • MTBF: 100,000 hours

Why choose it

The DU-550B balances cost and performance. Its Bronze efficiency reduces wasted energy and heat, while the 120 mm fan keeps noise low under typical loads. Fixed cables simplify installation in standard ATX cases.

Ideal use cases

  • Office workstations with integrated or entry-level graphics
  • Budget gaming PCs with up to a mid-range GPU
  • Home servers and NAS builds needing reliable 24/7 power

Good to know

This unit is designed for 200-240 V AC input, so it is suitable for European and Asian mains. The non-modular design means all cables are permanently attached, which is fine for most builds but can make cable management a bit more involved.
