550W ATX 3.1 power with fixed cables and Gold efficiency

550W / ATX 3.180 PLUS GoldNon-modular120mm HDB fan

The Cooler Master MWE Gold 550 V 3 is a 550W ATX 3.1 PC power supply with permanently attached cables, 80 PLUS Gold efficiency and a 120mm HDB cooling fan. Its compact 140mm body depth fits suitable ATX PSU bays, while one 24-pin mainboard connector, two EPS connectors, two PCIe6+2 connectors, six SATA and three peripheral connectors cover the documented power connections. This 550W model does not include the native 12V-2x6 cable offered on the 750W/850W versions.

Before you order:
Check the complete system power demand, case PSU bay and GPU power-connector requirements before ordering. Two PCIe6+2 plugs are on one 500+120mm cable run, not two independent GPU cables. A graphics card requiring native 12V-2x6 needs a separately suitable PSU or the GPU manufacturer-approved connection arrangement. ATX 3.1 compliance alone does not mean this 550W unit has every connector used by higher-wattage variants.

What's in the Box

  • 1 × MWE Gold 550 V 3 ATX 3.1 non-modular power supply
  • Permanently attached DC cables with the listed connectors
  • Additional accessories and mains-lead inclusion were not confirmed in the exact package list;check if these are required for your installation

What It Means in Practice

  • For a PC build, check the PSU bay and cable reach, then connect the mainboard, CPU, GPU and drives according to their manuals. Fixed cables remain attached even when unused, so allow room to route and secure them.
  • The 550W rating is total DC output. The single+12V rail is listed at 45.8A/549.6W, but rail limits cannot be added together beyond the 550W total.
  • 80 PLUS Gold and the listed≥90% typical-load efficiency describe conversion efficiency, not a guarantee that every operating load achieves the same percentage.
  • Compare connector layout as well as wattage: this model has two PCIe6+2 plugs on one run and no native 12V-2x6. A higher-power graphics card may require a different supply even when the mechanical ATX size fits.

What Will Not Work

  • Detaching unused cables as with a modular PSU.
  • Expecting a native 12V-2x6 connector on this 550W version or assuming its two PCIe plugs are separate cable runs.
  • Selecting a PSU only by the graphics-card connector shape without checking total system power and the GPU manufacturer requirements.

Frequently Asked Questions

Does the 550W model have 12V-2x6?
No. Cooler Master lists the native 12V-2x6 cable only on the 750W/850W versions of this series.
Are the two PCIe plugs two separate GPU cables?
No. The exact 550W datasheet specifies two 6+2-pin connectors on one 500+120mm cable run. Check the GPU manufacturer cabling requirements.
Can I remove unused cables?
No. This is the non-modular model, so unused cables remain attached and must be routed inside the case.
Singular Expert Insight
Choose this PSU for a system whose verified power needs and connector requirements fit the 550W model. The 140mm body depth can help in a compact ATX bay, but fixed-cable space and the single PCIe cable run still need checking. Do not transfer 750W/850W series features to this version.
