“Our new Professional Series HX850W and HX750W power supplies build on the phenomenal success of the award-winning Corsair HX620W PSU, offering even higher levels of performance, efficiency and reliability, including an industry-leading 7 Year Warranty” said Jim Carlton, VP of Marketing for Corsair, “The HX850W and HX750W have the power to handle the latest multi-core, multi-graphics PCs, and include the features that enthusiasts demand, including a comprehensive modular cable set and super-high efficiency.”

In addition to super-high efficiency, the Corsair HX850W and HX750W power supply units utilize a low-noise, temperature-controlled 140mm cooling fan, which use a specially modified fan-speed curve that prevents the fan from ‘spinning up’ until the PSU reaches 70% of the rated load. This ensures whisper-quiet running in typical PC configurations, even when gaming or performing processor-intensive tasks.

The Corsair Professional Series HX850W and HX750W PSUs both include powerful, single +12V rails and are qualified to deliver their full rated power output at an ambient temperature of 50°C, ensuring stability and reliability even under the most stressful conditions. A powerful +12V rail is essential for supporting today’s high-end components, which is why the HX850W can supply up to 99% of its total wattage (840W) on the +12V rail.
