    should I plug the additional 4 pins to the Motherboard
    « on: March 17, 2010, 01:22:46 AM »
    Hi all,

    Recently I bought a new power supply of 550W.
    When I tried to connect the 20 pins cord from the Power Supply to the motherboard,
    I saw there was an additional 4-pin head going together with the 20-pin head, and I noticed the warning message: only for 24-pin Socket.
    I do not know what this mean.
    Still, I chose not to plug it (the additional 4-pin socket), turned my PC on,
    and saw the windows run steadily without problem.

    I saw my Motherboard can support the additional 4 pins.
    I am not sure if I shall plug it to the motherboard or not.

    Please help if you could.
    Thank you.

    Kitty

    And then you say:

    Seems like you contradicted yourself. 

    What make and model is your motherboard?

      Here are the specification, and Feature of the new PSU:

      Specification:
      Type: ATX V2.2 / 2.3 (EPS 12V 2.91 for 900W / 1050W)
      Input Voltage: 100V~240V
      Input Current: 550~750W: Max 10A; 900~1050W: Max 13A
      140MM Exhaust Fan
      Dimension: 150 (W) X 158 (D) X 86 (H)
      MTBF: 100000hrs
      Effecticiency: 80%
      Hold Up time: >17ms
      Power Good Signal: 100~150ms]

      Feature:
      20/24 Pin Main Connector Available
      Support The New 8(6+2) Pin PCI Express Connector
      Support S-ATA II Tech., Up to 4(6) Connector
      2(4) PCI-Express Connector
      2(4) Independent Sets of +12V Output
      2(4) Sets Over Current Protection (OCP)
      Temperature Control Function inside

      I don't know if it will do any harm to the PC if a 24-pin socket on the motherboard is connected to a 20-pin connector.

      Input Current: 550~750W: Max 10A; 900~1050W: Max 13A
      Again, we have a contradiction.  Is it 550W or 1050W?  Based on the specs you posted, it's 1050W.  So, why did you say 550W in your original post?  And, why would you need a 1050W PSU?

      I don't know if it will do any harm to the PC if a 24-pin socket on the motherboard is connected to a 20-pin connector.
      But, your original post indicates the PSU connector has 24 pins; they're just divided into two parts, one being 20 pins and the other 4 pins.  Right?  So, just go ahead and connect both the 20 pin and 4 pin components of the connector from the PSU to the 24 pin socket on your motherboard.
