Congratulations on the purchase of your new Corsair HXi Series High Performance
ATX power supply.
HXi Series computer power supply units are designed for gaming rigs, overclocking
systems, or any PC where rock-solid stability is essential. Corsair HXi Series PSUs have
earned 80 PLUS Platinum certification to guarantee cool, quiet, efficient operation. Fully
modular cabling allows you to use just the cables you need, for better looking system
builds with improved airflow and less cable clutter.

Product features

Quiet, efficient operation
The HXi Series is certified 80 PLUS® Platinum, which results in lower heat generation and
a quieter fan profile. The HXi Series is so efficient that the 140mm fan doesn't even spin at
low loads for completely noiseless power delivery.
Corsair Link
™
Monitor power supply performance, toggle single rail or multi rail mode, and control fan
speed directly from your desktop by connecting the included cable to a motherboard USB
header and downloading the free Corsair Link Dashboard application.
Brilliant design
The fully modular cables make it easy to install and the fan self-test switch lets you quickly
determine if the fan is functioning normally at any time.
Technology and benefits
• 80 PLUS Platinum Efficiency
®
The sophisticated electrical design and state of the art components deliver extremely
high energy efficiency (92%).
• Outstanding DC voltage regulation
The HXi Series delivers exceptionally stable power over the whole load range
ensuring tight DC output voltage regulation without minimal ripple/noise, and
outstanding transient response.
• Low DC output voltage ripple and noise
The HXi Series features secondary side synchronous rectification for the
+12V rail utilizing MOSFETs that have lower losses than the conventional
output rectification schemes, and individual DC-DC regulation for the +3.3V and +5V
rails. While circuit trace optimization and advanced filtering techniques
help to minimize ripple and noise.
Designed for system builders
• Fully modular cable system
The fully-modular, low-profile cable system provides maximum 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.
• Fan Self test switch
The fan can be validated prior to system installation via a self test switch, which
confirms the fan is functional at any time.

Safety and protection

• Over-voltage protection (OVP)
Over-voltage protection for the 12V, 5V and 3.3V DC outputs is required to comply
with the ATX specification. OVP shuts down the PSU in the event that the DC outputs
exceed a set level, determined by the PSU manufacturer. The minimum voltage levels
required for compliance are 13.4V for the +12V rail(s), 5.74V for the +5V rail and 3.76V
for the 3.3V rail.
• Over-current protection (OCP)
The HXi Series features OCP on the 3.3V, 5V and 12V rails. OCP ensures that the
output of the DC voltage rails remains within safe operating limits. The
be configured as a single rail or multi-rail OCP solution.
• Over-temperature protection (OTP)
OTP ensures that the PSU will shut down when the internal temperature reaches a set
point. This is usually as a result of internal current overloading or a fan failure.
• Short-circuit protection (SCP)
A short-circuit is defined as any output impedance of less than 0.1 ohms. Amongst
other things, SCP ensures that the PSU shuts down should the 3.3V, 5V and 12V rails
short to any other rail, or to ground. It also ensures that no damage should occur to
the unit, or your PC's components in the event of a short.
