Installation Steps

Open your computer chassis; please refer to the instruction manual provided with your chassis.
Install the PSU into the case with the four screws provided.
If your motherboard requires a 24pin Main Power connector, please connect the 24pin Main Power connector to the motherboard.
For motherboards that only require a 4pin ATX 12V(CPU) connector, please detach a 4pin connector from the 4+4pin ATX 12V connector and connect it to the motherboard. (Either one of the 4pin from the 4+4pin ATX 12V connector will work)
For motherboards that requires a single 8pin EPS connector, please use the 4+4pin connector from the power supply.
Connect other peripheral power connectors to devices such as hard drives, optical drives, etc.
If your graphic card requires PCI-E power connector, please connect corresponding PCI-E connector instructed by your graphic card's user manual. Please note the power supply utilizes an unique 6+2pin PCI-E connector that can be effectively used as a single 8pin or 6pin PCI-E connector. To use it as a 6pin PCI-E connector, please detach the 2pin connector from the 6+2pin connector.
Close your computer case and connect the AC power cord to the power supply AC inlet.
Attention! When Smart Zero Fan System is turned on, the fan will not operate until the power supply reaches approximately 30% of rated load; It is normal if the fan does not operate when computer is at a low working load.
