Congratulations on the purchase of your new CORSAIR AX1600i Digital ATX power supply.
The CORSAIR AX1600i is a groundbreaking new design. It is a departure from traditional PSU designs and is packed
with features that will make building your ultimate dream PC even more enjoyable. The AX1600i introduces some new
and exciting technologies, so please read below for more information.
Product features
Digitally controlled power
Unlike traditional power supply designs, the CORSAIR AX1600i use a Digital Signal Processor (DSP) for optimized
efficiency and tighter voltage regulation, which improves overall system stability and component reliability.
Quiet, efficient operation
Upgrading to digital provides increased efficiency. The AX1600i is certified 80 PLUS® Titanium, which results in lower
heat generation and a quieter fan profile. The AX1600i is so efficient that the 140mm fan doesn't even spin at low loads
for completely noiseless power delivery.
CORSAIR Link ™
The built-in CORSAIR Link functionality shows you how your AX1600i is performing at any given moment and lets you
™
quickly tweak its performance. Server-inspired diagnostic tools monitor real-time efficiency, power usage, configurable
over-current protection points and fan profiles.
Brilliant design
The fully modular cables make it easy to install and the self-test switch lets you quickly determine if the power supply is
functioning normally before you even attach cables to your motherboard.
Technology and benefits
• Totem Pole PFC GaN power switches
By using GaN (Gallium Nitride) components in the totem pole PFC circuit, efficiency is increased, reducing the
need for the larger heat sink required for typical Si (Silicon) parts. GaN parts are also smaller than Si parts.
• Digital control
The AX1600i features an advanced control architecture to produce outstanding dynamic response. It features
a true digital engine that provides superior on-the-fly performance optimization across the full operating range
while maintaining stable operation.
• 80 PLUS Titanium Efficiency
®
The sophisticated electrical design, incorporating advanced hybrid digital control and state of the art magnetics
delivers extremely high energy efficiency (over 94%).
• Outstanding DC voltage regulation
Due to its digital design, the AX1600i delivers exceptionally stable power over the whole load range and
automatically compensates for DC output cable voltage drop, ensuring tight DC output voltage regulation without
the ripple/noise, transient response, and converter stability drawbacks associated with conventional power supply
designs.
• Low DC output voltage ripple and noise
The AX1600i 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. An
advanced 4-layer modular connector board PCB ensures a better ground return plane, lower resistance and low
voltage drops. This, combined with circuit trace optimization and advanced filtering techniques, helps to minimize
ripple and noise.

• Reduced component count and increased reliability
The digital control of the AX1600i eliminates many external components required by more conventional PSU
solutions to offer an extremely small, high density, high reliability solution that allows incremental space to add
extra features — like real time parameter monitoring and power supply control.
User friendly features
• 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.
• Self-test switch
The power supply can be validated prior to system installation via a self-test switch, which confirms all DC output
voltage rails are present and the fan is functional.
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 AX1600i 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 AX1600i
• 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.
• Under-voltage protection (UVP)
Under-voltage protection for the 12V, 5V and 3.3V DC outputs shuts down the PSU in the event that the DC
outputs drop below a set level, determined by the
PSU manufacturer.
• Over-power protection (OPP)
Over-power protection will cause the PSU to latch in the event that the PSU's power demands exceed the
PSU's capability.
AX i S E R I E S
can be configured as a single rail or multi-rail OCP solution.
