Announced at Computex: The HXi Series Power Supplies


Last week during Computex in Taipei, Taiwan, Corsair introduced the new HXi Series of PC power supplies. The series consists of a 750, 850 and 1000W. The HXi continues the tradition of the previous HX Series with many of its features and specifications. Like the HX, the units are rated to output continuously even at temperature as high as 50°C rating. They feature 100% Japanese electrolytic capacitors rated at 105°C. Voltage regulation is better than 2% +/- and ripple/noise is kept well under 40mV.


The HXi is fully modular and features a Zero-RPM fan mode that allows the PSU to run perfectly silent at loads up to 40%.

Below is a diagram showing the fan noise of all of the HXi models:




The HXi's also get a bump in efficiency over the previous HX Series with an 80 Plus Platinum efficiency rating from Ecova. Below are the charts that illustrate the efficiency of the HXi series:




The HXi also supports Corsair's Link dashboard software. To interface, the user can either connect either the I2C or USB connector on the PSU.


Using the Link software, the user will be able to monitor AC power in and DC power out and calculate efficiency. The +12V, +5V and +3.3V voltage and current are also measured, as well as PSU temperature and fan speed.


Another function in Link is the ability to turn your PSU from a multiple +12V rail to a single +12V rail unit. When "Multi-Rail Mode" is enabled, an OCP (over current protection) of 30A is applied to each 8-pin modular connector, 40A on the 24-pin connector and 30A on all of the combined 6-pin modular connectors. When "Multi-Rail Mode" is disabled, the PSU acts as a single +12V rail PSU.

The HXi Series PSUs are backed by a seven-year warranty and will be available from Corsair's worldwide network of authorized retailers and distributors in August 2014.
