CORSAIR HXi SERIES

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.

OCP is featured on the 3.3V, 5V, and 12V rails. OCP ensures that the output of the DC voltage rails remains within safe operating limits.

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.

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.

Over-power protection shuts off the PSU when the power drawn is between 115% and 135% of the rated power.

If you are building a new system, skip to Step 2.

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 PSU.

4. Proceed to Step 2.

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 24-pin (ATX12V) cable to the motherboard. Connect the 8-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.

c. Some motherboards will require a mix of 8+4 pins, use as many EPS12V cables as necessary and do not mistake them for PCIe cables.

4. Connect the peripheral cables, PCI-Express cables, and SATA cables.

a. Connect the SATA cables to your SATA SSD or hard drive’s power sockets.

b. Connect the PCIe cables (or the 12VHPWR cable) to the power connector of your GPU.

c. Connect the peripheral cables to any peripherals requiring a 4-pin connector.

d. Make sure all the cables are tightly connected. Be sure to save any unused modular cables for future component additions.

e. Connect the 6-pin portion of the 6+2-pin PCIe cable to the iCUE LINK System Hub if you have one.

5. Connect the AC power cord to the power supply and turn it on by pushing the switch to the ON position (marked with “I”).

Install and Update iCUE

The HXi power supply boasts a range of connectivity options for any system. Users can take advantage of CORSAIR’s robust iCUE software to monitor power settings, toggle between single to multi-rail overcurrent protection (OCP) on-the-fly, or create custom fan profiles.
