Table of contents


This guide is a general introduction to PSU (Power Supply Unit or Power Supply) installation. The installation procedure may vary with different PSU and case types. Please refer to your PSU, case and other component manuals for detailed instructions.

Installation Procedure

1. Before the Installation

Ensure the power supply is set to 115V mode when used in the United States by checking the AC voltage switch position (115V and 230V or 110 and 220V).

Attention: The incorrect AC voltage will damage the power supply.

2. Install the PSU into PC case

Slide the PSU into the position from the inside of the PC case; secure the PSU with screws.

Note: Certain types of cases are designed for PSU installation from the outside (a PSU cover located on the case may need to be removed before installation), see your case manual for more information.

3. Motherboard and Graphics Card Connection

Plug the 20-pin/24-pin main power connector into the motherboard's matching power connector.

Today's motherboards often feature 4-pin or 8-pin 12V power connector support, make sure the corresponding power connector from the PSU is properly plugged in.

High-end graphics cards often require extra power support; plug the corresponding power connector (generally a 6-pin power connector for PCIe graphics cards) into the graphics card's connector. If your PSU does not provide the appropriate power connector, use the power connector adaptor that comes with your graphics card.

4. Connecting Other Devices

Connect the 4-pin connector, SATA connector and 4-pin floppy connector into the corresponding devices

Important note: Most connectors are purpose-designed to prevent incorrect connections. If you cannot attach a female power connector to a drive's or peripheral's male connector; please check that the connectors are attached in the correct orientation. DO NOT forcefully connect a female connector to a male connector in the incorrect orientation, or modify any of the components, as this can damage the PSU and the connected devices.

5. PSU Fan Monitor/Fan Control Connection

Selected PSUs come with fan monitor/fan control connectors. If you want the motherboard to detect and/or control the PSU fan speed, please plug the PSU fan speed/fan control connector into the motherboard's corresponding header (often labeled as PWR_FAN).

6. Power On

Check and make sure all devices are well connected with the PSU. Plug the AC cord into the PSU's AC inlet and then switch the power to "on" if your PSU has an on/off switch. Your system is ready to go – just press the power on button and you're ready to go!
