Seasonic FOCUS SPX-750 (2021) 750W - PSU, 80 Plus Platinum

The Seasonic FOCUS SPX-750W (2021) is a power supply unit engineered for high-performance systems within a compact footprint. It delivers a nominal power output of 750 watts and holds an 80 PLUS Platinum certification, signifying up to 92% efficiency at 50% system load. This high efficiency rating results in reduced energy consumption and less heat generation. The unit utilizes a fully modular cabling design, allowing for a cleaner build process and improved internal airflow by using only the required cables. Its SFX form factor is intended for small-form-factor (SFF) builds that require substantial, stable power.

Thermal performance is managed by a 92mm fan with a three-stage hybrid control system. This technology provides a fanless mode at low loads for silent operation, transitioning to quiet and active cooling modes as power draw increases. The power supply is equipped with a comprehensive set of protection features, including Over Power (OPP), Over Voltage (OVP), and Short Circuit Protection (SCP), to safeguard connected components. Designed to operate in ambient temperatures up to 50°C, the unit maintains consistent performance under demanding thermal conditions.
