Overview

A high-level hybrid-cooled power supply

Built with quality components, this Seasonic FOCUS PX Platinum power supply will always provide impeccable voltage and outstanding reliability for long term use. This highly efficient unit incorporates an innovative fan control system that allows the fan to not start at low load and only start when the temperature requires cooling. If you want the fan to be always on, simply press the hybrid mode button on the back of the power supply. Fully modular, it allows for a clean, customisable installation while helping to improve internal airflow.

Hydrodynamic Bearing Fan (FDB)

High performance hydrodynamic bearing fans (FDB) are designed to take advantage of the impact of oil absorption effects. They are extremely reliable and generate much less noise and heat during operation than ball bearing fans. Lubrication of the bearing surface reduces friction and vibration, which also reduces the fan's overall power consumption. With smoother, quieter rotation and quality construction, this highly reliable technology also increases the life of the fan.

As the fan shaft rotates, high-pressure oil spreads along the grooves in the bearing sleeve to create a thin layer of lubrication on the ball bearing. As the speed increases, so does the dynamic pressure of the oil. The fan shaft then lifts off the bearing to rotate effortlessly. The chevron shape of the grooves ensures that the lubricant is channelled effectively and thus prevents leakage.

Hybrid fan control for quieter operation

Seasonic 's vast experience in developing the most efficient and quietest power supplies on the market has been translated into the development of Hybrid Mode; a state-of-the-art fan control that allows users to keep noise levels as low as possible.

The latest Seasonic platform keeps output voltages within a very tight margin with less than 0.5% variation under load. This impressive performance and electrical stability makes this power supply the ideal choice for all high-performance machines. In addition, the Seasonic FOCUS series is designed with a reduced acoustic signature to reduce operating noise.

80PLUS Platinum certification and cable-free design

Seasonic 's FOCUS PX Platinum series achieves 80PLUS Platinum certification with an efficiency of 92% at 50% system load.

Seasonic's ongoing commitment to the development of quality analog power supplies has resulted in ripple levels well below the average industry standard of 20mV. Seasonic engineers have implemented a new internal design where, instead of cables, the backplane and PCB (Printed Circuit Board) are connected by a copper plate. This advance not only reduces the chance of production errors during the manual manufacturing phases but also improves the quality of the output voltages.

    Modularity at its best

    The pluses :
    - Almost permanent fanless mode (silence)
    - Highly practical cable modularity
    - Large selection of SATA cables
    - Clean, reliable and solid hardware feeling

    Minus :
    - Heavy to handle
    - The ribbon cables are not easy to store neatly in the case
    - Compare your needs with the same model stamped "LDLC GT-550P Quality Select 80PLUS Platinum" which has fewer cables
