The OP series marches on with the design of OP850, the fine form established by the first SilverStone performance single +12V rail Zeus ST56ZF. Precision manufactured by industry leading robotics assembly line and designed by SilverStone’s world-class PSU engineering team, the OP850 is packed with serious power with supreme performance. With a single +12V rail continuous output up to 70A at 50°C, this peerless power is harnessed in a compact enclosure and cooled by a high quality 120mm fan tuned to perfection. Combining these performance and ergonomic attributes into a power supply such as the OP850 is a dream come true not only for ardent enthusiasts but also for those who are simply looking for the best.
