The Platinum Series SS-860XP2 860W 80 Plus Platinum Modular Power Supply from Sea Sonic Electronics is designed for high-performance systems where reliability is essential. It offers tight voltage regulation that keeps voltage fluctuations on the 12 V output within 0-2% to provide smooth and stable operation. Furthermore, the 80 Plus Platinum efficiency rating ensures power savings with up to 92% efficiency and a true power factor of greater than 0.9PF.
A fully modular design allows you to use only the cables that you need, minimizing cable clutter and simplifying cable management. The power supply employs Hybrid Silent Fan Control, which offers fanless, silent, and standard cooling modes to balance between silence and cooling. In addition, it uses high-quality conductive polymer aluminum solid capacitors and 105°C Japanese aluminum electrolytic capacitors for stable operation under extreme conditions and extended life.
DC Connector Panel with integrated voltage regulator module (VRM) minimizes voltage drops and impedance - enhances overall performance and reliability
Easy swap connectors can be unplugged easily, quickly, and safely
DC to DC converter design provides high dynamic response and system stability, and maximizes the 12 VDC rail output
Sanyo Denki San Ace Silent Fan features spoon shaped high-density plastic blades with smooth leading edges, strict tolerance bearings, and precision copper axel to ensure virtually silent performance
Seasonic Hybrid Silent Fan Control provides Fanless, Silent, and Cooling modes to balance between silence and cooling - reduces noise without increase in temperature, extends fan life, optimizes heat dissipation, and virtually silent performance with Fanless mode enabled
