Silverstone ML02-MXR - can’t turn new build pc on

  • I have recently bought the old HTPC case Silverstone ML02-MXR for my first pc build.



    Problem description


    When I plug the power cable into the case and turn the power on on the wall, the iMon display turns on and light and also the diodes on the keyboard light for some seconds and the optical mouse light continuously (they are both connected by PS2), but nothing else happens. There seems to be no display signal to my apple display (which I have tested works) and I can’t hear the HHD spin and the fans also doesn’t turn on. And if I try to press the power button or holding it down for 10 seconds afterwards nothing more happens.



    Correctly cable connections... ?


    I wonder if I have connected the cables to and from the iMon display hardware card correctly...


    I have connected:


    1) The black, red and purple triple wire on the iMon hardware card with the black, red and purple triple wire from the 20 + 4 ATX power connector.


    2) The red and black duo wire on the iMon hardware card with the power button connector (PWRBTN#) at the System header on the motherboard.


    3) The blue and white wire from the power button on the case to the duo connector on the iMon hardware card with the blue wire beneath the white wire.


    Should I instead have placed the white wire beneath the blue one, or doesn’t it matter ?


    In case I have connected the cables wrongly, I would like to know how others who have worked with the Silverstone ML02-MXR have connected the iMon hardware card and the power button on the case of the SilverStone ML02 ?


    In case you think it’s easier, you may also insert some pictures of how you connected the iMon hardware card and the power button on the case of the SilverStone ML02.

  • I am not sure, but maybe the CPU needs another (second!) power cable to be plugged into the power supply?

    Or maybe 120 W Power Supply has just not enought power for such new CPUs?

    Are there any beeping tones or flickering lights on the motherboard which show the error cause?

  • My b450 Board have to connect with a full 8pol 12v connector. I bought a 4pol->8pol adapter.

    120w could be also the Problem. Can you try a different PSU with more Power? In the BIOS settings you can limit the CPU. As an First Test,i would Limit it to 45W and try the Pico again.
