Cooler Master MASTERWATT550 SEMI-FANLESS MOUDULAR 80 PLUS BRONZE CERTIFIED 550 Watt POWER SUPPLY With 5 years warranty
Cooler Master MASTERWATT550 POWER SUPPLY
Cooler Master Watt 550 is a reliable, efficient, and well-designed power supply built for users who want stable performance without unnecessary noise. This 550W unit is 80 Plus Bronze certified, delivering up to 85% efficiency under typical loads, helping reduce heat and power waste while keeping your system running smoothly. Its semi-fanless design allows the 120mm LDB bearing fan to remain off during low to moderate workloads, giving you silent operation when your PC is idle or handling everyday tasks. As load increases, the fan adjusts accordingly, ensuring balanced cooling and quieter operation than traditional power supplies. The unit features Active PFC, ATX 12V v2.4 support, and a comprehensive set of protections, including OPP, OVP, UVP, OCP, OTP, and SCP, to eliminate risks from unstable voltage or power surges. With its semi-modular cables, you only use the connectors you need, improving airflow and maintaining a clean interior for better long-term performance. The PSU includes all essential connectors—MB 20+4 pin, CPU 4+4 pin, two PCI-E 6+2 pin, six SATA power ports, and peripheral connectors, making it suitable for mid-range gaming builds, productivity PCs, and general home or office systems. Built with strict regulatory certifications such as CE, FCC, TUV-RH, RCM, EAC, BSMI, KC, and CB, the MasterWatt 550 ensures dependable quality and global safety compliance. Compact dimensions of 140 × 150 × 86 mm allow compatibility with most ATX cases, while an MTBF of over 100,000 hours ensures long service life. Combining stable output, silent operation, and reliable hardware protection, the Cooler Master MasterWatt 550 stands out as a strong, practical choice for users seeking a trustworthy power supply for daily use or gaming.
