Installation Steps
Note: Make sure that your system is turned off and unplugged.
Disconnect the AC power cord from your old power supply.
Step 1: Removing Your Existing Power Supply
- Make sure that your system is turned off and unplugged.
- Disconnect the AC power cord from your wall outlet or UPS and the existing power supply.
- Disconnect all the power cables from your graphic card, motherboard, and all other peripherals.
- Follow the directions in your chassis manual and uninstall your existing PSU.
Step 2: Installing the New Power Supply
- Make sure the power supply’s AC power cable is not connected.
- Follow the directions in your chassis manual and install the power supply with the screws provided.
- Connect the 24-pin or 20-pin main power cable to the motherboard.
- Connect the eight-pin +12V (EPS12V) cable to the motherboard.
- If your motherboard has an eight-pin +12V socket, connect the eight-pin cable directly to your motherboard.
- 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.
- Connect the peripheral cables, PCI-Express cables, and SATA cables.
- Connect the SATA power connector to devices with a Serial ATA interface.
- Connect the 6+2pin or 12+4pin PCI-E power connector to the PCI-E graphics cards if required.
- Connect the 4-pin peripheral power connector to peripherals devices if needed.
- Connect the AC power cord to the power supply and turn it on by pushing the switch to the ON position (marked with “I”).
Attention! When the Smart Zero Fan mode is turned on, the fan will not spin until the load exceeds 30% of the power supply, minimizing the fan noise; It is normal if the fan does not operate when the computer is at a low working load.
