Corsair today announced the general retail availability of the Professional Series Gold AX1200, AX850, and AX750 power supply units.
These PSUs, which feature 80 PLUS GOLD certification, were announced and shown at Computex in Taipei.
Corsair claims that its Professional Series Gold power supplies exceed the requirements for 80 Plus Gold certification, delivering over 90% efficiency at 50% load when using a 115V AC input. This increases to over 92% efficiency when used with the 230V AC voltage input specification in Europe.
Corsair Professional Series Gold power supplies are provided with a seven year limited warranty, and are backed by Corsair?s customer service and technical support.
Summary of Key Features
The Professional Series Gold AX1200 has been designed from the ground-up by Corsair?s power engineering team, and is therefore unique and exclusive to Corsair.
The AX1200?s massive 100.4 Amp (1204.8 Watt) single +12V rail makes it the ideal power supply for high end NVIDIA SLI and ATI CrossFireX gaming PCs based around multi-core CPUs.
The sophisticated electrical design, incorporating advanced magnetic modeling during development in order to optimize magnetic component performance, delivers high energy efficiency (90% and above). This meets or exceeds the requirements for 80 Plus Gold certification.
The AX1200 features individual DC-DC regulation for 3.3V, 5V and 12V rails, and secondary side synchronous rectification, utilizing MOSFETs that have lower losses than the conventional output rectification schemes. A 4-layer modular connector board PCB ensures a better ground return plane, lower resistance and low voltage drops. This, combined with circuit trace optimization, also helps to minimize ripple and noise.
The fully-modular, low-profile cable system provides flexibility when building or upgrading your PC, and maximum airflow through your chassis. This allows you to utilize only the cables that you need, reducing cable clutter and maximizing the cooling performance of your PC.
The Corsair AX1200 utilizes ZVS / ZCS technology to switch at near 0V and 0A, which ensures there are minimal switching losses, thereby maximizing efficiency and further reducing waste heat.
The AX1200 utilizes a low-noise, thermally-controlled 140mm fan, and employs techniques to enhance cooling performance and reduce noise. This includes a specially designed PCB that channels airflow to reduce back-pressure and maximize the fan?s cooling ability.
