## Long description

The Cooler Master G Gold 550 V2 550W is a 550-watt ATX power supply unit designed for desktop PCs and compact workstations. It features 80 PLUS Gold efficiency, DC-to-DC + LLC circuit topology, a quiet hydrodynamic bearing (HDB) fan, and compliance with ATX 3.1 to support peak power demands of modern GPUs. The unit includes a 24-pin ATX connector, two 4-pin EPS connectors, multiple SATA power cables and an embossed cable texture for improved handling.
Advantages
The G Gold 550 V2 delivers high conversion efficiency (80 PLUS Gold) and stable voltages thanks to DC-to-DC circuitry and a single +12V rail. A hydrodynamic bearing fan provides long-lasting, quiet cooling while the design supports operation up to 40°C. ATX 3.1 compatibility ensures the PSU can handle elevated peak loads required by current-generation graphics cards. Embossed cables improve grip and cable routing during installation.
Suitable for
Mid-range gaming PCs with up to 550W system draw
Workstations that require stable +12V supply and ATX 3.1 support
Systems using 40-series or similarly demanding GPUs (peak load scenarios)
Compact builds needing a reliable, efficient PSU with quiet cooling
Key specifications

How to use
Install the Cooler Master G Gold 550 V2 into a compatible ATX case and secure it with the supplied screws. Connect the 24-pin ATX cable to the motherboard and attach the two 4-pin EPS connectors to the CPU power headers as required by your motherboard. Route and connect SATA and peripheral cables to storage and other devices. Ensure the PSU is connected to an appropriate AC supply (100–240 V, 50/60 Hz). After connections are made, power on the system and verify stable operation and proper fan function.
Usage recommendations
For reliable performance, use this power supply with systems whose continuous power draw stays within the 550 W rating, allow adequate case airflow for cooling, and keep ambient temperature below 40°C. The ATX 3.1 support makes it suitable for systems that experience short peak loads from modern GPUs, but confirm total system power requirements when planning upgrades.
