LEPA MX F1 N400-SB-EU User Manual

1. Please read your system component manual to know what kinds of DC connectors are needed to be applied and 

    other relative installation tips.
2. Place the power supply into the chassis corresponding location. To ensure ideal system ventilation, and do not  

    block power supply air intake and exhaust area.
3. Connect the DC connector to system component, if required. Do not need to plug the AC cord to power supply at 

    this stage yet.
4. Following table describes purpose of DC connectors.  Connector types might differ by models.

    Some advance motherboard requires not only 24-pin main power and 8-pin CPU connector, but also other 

    peripheral power connectors to share the current and increase the stability. We recommend applying the other 

    peripheral power connectors to it if your system consists of multiple graphic cards.
5. Plug the AC cord to the power supply, and turn the “I/O” switch to “I” location. Then your system is ready to 

    work.
