The PSU is built using high-quality components, including Japanese capacitors, which are known for their long lifespan and stability. The unit also features Active Power Factor Correction (PFC), which ensures that the power supply is always delivering power at the optimal phase, reducing power loss and improving overall system efficiency.

The Cooler Master MasterWatt 550W 80 ATX PSU is also compact and quiet, with a size of just 140mm (H) x 150mm (W) x 86mm (D), making it a great option for small form factor cases. It also features a 120mm fan, which provides efficient cooling while operating quietly, allowing you to focus on your gaming or work without distraction.
