Installing your NEW HXi Series
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
power supply.
2. Disconnect all the power cables from your video card, motherboard and all other
peripherals.
3. Follow the directions in your chassis manual and uninstall your existing power supply.
4. Proceed to Step B.
Step B: Installing the Corsair HXi Series power supply
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. 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.
WARNING: The detachable four-pin from the 24-pin main connector is not a "P4"
or "+12V" connector. Serious damage can be caused if you use it in place of a "P4"
or "+12V" connector.
