Introduction
Corsair power supplies are designed for worry-free compatibility for your desktop PC
system build or upgrade. With the features to be expect from a premium power supply, it’s
a great choice for systems where continuous and reliable power delivery and low noise are
essential.
Your Corsair power supply is packed with the latest technology and features:
• CX750, CX750M, GS, TX, TX-M, GS, CS-M, HX, AX and AXi Series support the latest
ATX12V2.4 standard and is backward compatible with ATX12V2.31 and earlier, as well as
ATX 2.2 and earlier systems.
• CX600, CX600M and lower wattages in the CX and CX-M Series and VS Series support
the ATX12V3.1 and is backwards compatible with all earlier ATX12V systems as well.
• All Corsair power supplies feature a thermostatically controlled intake fan that will vary
fan speed in response to temperature. The result is a quieter power supply at low loads.
• Corsair’s GS, TX, TX-M, RM, HX, AX (not including AX1200) and AXi all feature a Zero
RPM fan mode. At low loads, the intake fan will not spin, allowing the power supply to
operate in absolute silence.
• All of Corsair’s power supplies are at least 80% ecient at loads of 10% and greater.
• 0.99 Active Power Factor Correction provides clean and reliable power.
• A dedicated single +12V rail oers maximum compatibility with the latest components.
• Over-voltage and over-power protection, under-voltage protection, and short circuit
protection provide maximum safety to your critical system components.
• Extra-long cables support full tower chassis.
• Cables are either sleeved or are flat ribbon-style for improved aesthetics and better
airflow
• Modular units, such as the CX-M, TX-M, CS-M, RM, HX, AX and AXi, allow users to remove
cables. This makes installation easier and allows the customer to eliminate unused cables,
which reduces cable clutter within the chassis.
• Up to a seven year warranty and lifetime access to Corsair’s legendary technical support
and customer service.

PSU MANUAL
WARNING: The detachable four-pin from the 24-pin main connector is not a “P4”

Installation
Before proceeding with installation, please read this manual in its entirety.
Step A: Removing your existing power supply
If you are building a new system, skip to Step B.
1. Disconnect the AC power cord from your wall outlet or UPS and from the existing

1. Make sure the power supply’s AC power cable is not connected.
2. Follow the directions in your chassis manual and install the power supply with
the screws provided.
3. Connect the main 24-pin power cable. The main 24-pin power cable has a detachable
4-pin mechanism in order to support either a 24-pin or a 20-pin socket on the
motherboard.
A. If your motherboard has a 24-pin socket, you may connect the 24-pin main
power cable from the power supply directly to your motherboard.
B. If your motherboard has a 20-pin socket, you must detach the four-pin
cable from the 24-pin connector, and then plug the 20-pin cable onto your
motherboard without connecting the four-pin connector.
4. Connect the eight-pin +12V (EPS12V) cable to the motherboard.
A. If your motherboard has an eight-pin +12V socket, connect the eight-pin
cable directly to your motherboard.
B. If your motherboard has a four-pin socket, detach the four-pin from the
eight-pin cable, and then plug this four-pin cable directly to your motherboard.
5. Connect the peripheral cables, PCI-Express cables, and SATA cables.
A. Connect the peripherals cables to your hard drive and CD-ROM/DVD-ROM
power sockets.
B. Connect the SATA cables to your SATA SSD or hard drive’s power sockets.
C. Connect the PCI-Express cables to the power sockets of your PCI-Express
video cards if required.
D. Connect the peripheral cables to any peripherals requiring a small 4-pin connector.
E. Make sure all the cables are tightly connected. Be sure to save any unused modular
cables for future component additions.
6. Connect the AC power cord to the power supply and turn it on by pushing the switch
to the ON position (marked with “I”).
