Introduction and Features
Corsair continues to bring a full line of high quality power supplies, memory components, cases, cooling components, SSDs and accessories to market for the PC enthusiast and professional alike. Corsair's updated Professional Series HX power supplies include four models; the HX650, HX750, HX850 and HX1050. All of the power supplies in the Professional Series feature modular cables, premium quality components, an energy-efficient design (now 80 Plus Gold certified) and quiet operation; and they are backed by a 7-year warranty and lifetime access to Corsair's comprehensive technical support and customer service. The most obvious differences between the new models and the old Professional Series HX PSUs are the new 80 Plus Gold efficiency certification (upgraded from 80 Plus Silver) and the ability to operate in fanless-mode.
Here is what Corsair has to say about their new Professional Series HX PSUs:
"Legendary Performance and Reliability
Corsair Professional Series HX power supplies are designed for PC builders and upgraders who need a highly efficient, quiet, and supremely-reliable power supply, with a modular cable-set that makes installation a breeze.
Quiet Operation at Low Loads
Thanks to their highly-efficient design, Corsair Professional Series power supplies generate minimal heat, and are able to operate in a silent, fully-fanless mode at up to 20% of the PSU’s maximum load (170W for the HX850). This means that Professional Series HX PSUs will be completely silent when you’re performing less intensive tasks, such as web browsing or chatting in forums. And the thermally-controlled fan spins up gradually above 20% load, so that it still operates quietly during normal use and when gaming. Basic PC power supplies have fans that spin all the time your PC is on – whether you’re pushing your graphics card to the limit or just surfing the web – making them noisier and more intrusive.
Modular Cables for Easy Installation
Professional Series power supplies have a comprehensive modular cable set that allows you to use only the cables you need for your particular set of components. The benefits of this include a cleaner, neater installation, and that ‘professionally-built’ look, plus increased airflow through the case due to reduced cable clutter. The cables are also long enough to support full-tower cases.
80 PLUS Gold: High Efficiency – Low Heat
Efficiency is the measurement of how effectively a power supply converts AC power from your wall outlet to the DC power used by your PC’s components. If your power supply isn’t efficient, it will generate more heat, which requires more cooling and more fan noise. And, it might even affect your power bill.
Professional Series HX PSUs are among the most efficient on the market. Each model has 80 Plus Gold certification, which ensures up to 90% energy-efficiency. This helps to keep your PC cool and quiet, and it may even save you money too.
Professional Series HX PSUs are built with premium components, such as 105°C capacitors, and are capable of continuous power delivery at a temperature rating of 50°C, ensuring maximum performance and reliability even in the most demanding and hot-running performance PCs.
The Corsair Advantage
Corsair Professional Series PSUs are backed by a reassuring 7-year warranty and comprehensive customer support via telephone, email, forum and the Tech Support Express helpdesk."

We have seen a wireless streaming graphics card which reminded the crew at PC Perspective of Cthulu, but we have not yet released the Kraken. That was up to Corsair and their HX850 PSU which [H]ard|OCP recently reviewed. A single 12V rail is capable of delivering up to 70 amps which is a good thing on a PSU with six 6+2 PCIe power connectors but it still wasn't enough to really impress [H]. This PSU has essentially been released to refresh their current model and while it does match the performance of the previous model it does not really improve upon it. This is what lead to [H]'s disappointment, the PSU passes the tests but has not really improved from the model Corsair was selling years ago. Still it is a decent choice for a system builder who plans on using multiple GPUs.
"Corsair, a brand we have come to trust when powering our enthusiast desktop PC systems, brings to us an 850 watt power supply unit that touts quiet operation, a modular configuration, and "gold" rated power efficiency. How does the new Corsair HX850 fit into Corsair's current power supply lineup?"
