Power Supply with 80 PLUS Bronze Efficiency and Powerful 45.5A Single RailThe Seasonic S12III is a high-performance power supply that provides a total output of 550 Watts to make it ideal for even high-end gaming PCs. The powerful 12 Volt rail delivers a full 45.5A and the unit has the respected 80 PLUS Bronze efficiency certification. Seasonic always opts for premium quality electronic components, including LLC transformers.
The Seasonic S12III 550 Watt includes a 24-pin- and a 4+4-pin cable, along with two 6+2-pin PCIe connectors as well as six SATA-, three 4-pin Molex connectors and a floppy connector. This connectivity makes the unit perfect for all manner of systems. Visually the unit fits in perfectly with just about any case thanks to it coming in black.
Automatic Fan Control with Semi-Passive ModeThe pre-installed 120 mm fan uses quiet-running bearings, that mean the PSU remains extremely quiet during operation. This is also important for long-term durability and reliability. Seasonic's auto-start Smart-and-Silent fan control tech allows the fan to only switch on at 50 percent load. This results in a significant reduction in unwanted noise, while retaining the maximum possible cooling performance in reserve for when it's needed.
It almost goes without saying at this point that the Seasonic S12III series includes all the important safety features we have come to expect from modern high-end power supplies. The load regulation operates within an extremely tight voltage tolerance. Additionally, Seasonic provides a five year guarantee to go along with it.
