INSTALLING YOUR RMx SERIES POWER SUPPLY


STEP 1: REMOVING YOUR EXISTING POWER SUPPLY

WARNING: To ensure proper function, only use the DC cables included with your PSU, unless your old cables are genuine CORSAIR cables of the same type. Please confirm your existing cables’ type before using them!

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.


STEP 2: INSTALLING THE NEW 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. 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 PCI-Express cables to the power sockets of your PCI-Express video cards if required.

c. Connect the 16-pin 12V-2x6 connector to the power socket of your GPU if required.

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

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

5. Connect the AC power cord to the power supply and turn it on by pushing the switch to the ON position.


RMx SERIES FANS SPECIAL FEATURES


FAN SPEED KNOB

Use this knob to override the Zero RPM fan mode and adjust the minimum starting fan speed.

NOTE: If PSU temperatures require greater airflow, the PSU's fan controller will override the knob's setting as needed.

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.

UNDER-VOLTAGE PROTECTION (UVP)

Under-voltage protection for the 12V, 5V and 3.3V DC outputs is required to comply with the ATX specification. UVP shuts down the PSU in the event that the DC outputs drop below a set level.

OVER-CURRENT PROTECTION (OCP)

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.

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.

OVER-POWER PROTECTION (OPP)

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