Silent Pro Gold 1000W Ranging from the ever-efficient 600W all the way up to the 1200W power supply, the Silent Pro Gold will satisfy the energy cravings of any system. With a power efficiency rating of 90%, the Silent Pro Gold line meets the 80Plus Gold Standard. To achieve this goal, Cooler Master incorporates three visionary patents into this innovative design. The Hybrid Transformer„¢ incorporates the transformer with the heat sink, not only reducing the size by 25% over traditional transformers, but by keenly conducting heat, superiorly increasing efficiency. The Heat Transfer Technology„¢ crafted especially for powerful, demanding power units utilizes and L-shaped design to ingeniously route air flow by the heat sink, resulting in greater heat dissipation and therefore providing an optimal performance. The Hyper Path„¢ adeptly places the integrated circuits tightly to the transformers, shortening the path and creating a more direct energy channel, reducing the energy loss to nearly nothing. Combining these elements with the integrated active PFC with PWN controller, an intelligent 120/135 mm speed-adjustable fan, a powerful single rail engaging the most energy-greedy peripherals with ease, and countless other features, the Silent Pro Gold Series will handle all your computer power needs.
