The Switch is non-powered except by the board.
Black should go to power or + side

It's like a wall switch for the light (power comes in on one side and out on the other) If it were a push in to a detent (like the Old 386's and 486's with AT power supply) to connect and a push in to release the detent it would make a difference. With these power buttons on the cases now, it doesn't.

I replace my power supply for my E520 and its dose not turn on. It is a new replacement power supply for this model. I check alll the connections. It haas aa blinking amber light all time.


I would double check the connections to the main board. Some power supplies have two power connectors to the mother board, a 20 pin connector and a 4 pin connector. Sometimes the four pin connector is in a different location from the 20 pin on the board. Make sure both connectors a plugged in.

Make sure the connector for the power switch is plugged into the board. Dell's usually have all the wires for the front pane in one connector.

You should also unplug everything from the board except the power supply and front panel. There could be a hard device causing the board to hang up.

I have had power supplies die and short the main board. I hope that isn't the case here.

Don't have manual and I am not sure how to connect the power switch, reset switch, power LED and HDD LED


if you do not have the manual it's here.

http://www.msi.com/index.php?func=downloaddetail&type=manual&maincat_no=1&prod_no=260

those leads go on pins that are together usually by one edge of the board.They are hard to see but are marked.you should be able to see the reset and power switch quite clearly and if the leads are not lablelled then trace them back to the small reset switch and the power on switch

How to link case wires on the mother board? I've lost the manual and i don't find any stuff on chaintech website...


hi

  • Locate the case connector pins on your motherboard. This will be a bank of two rows with 10-12 pins in each row. Each pin will be about 1 cm in length.
  • Step 2 Locate the power lead behind the power button on your computer case. The lead will consist of two thin wires, usually white and black, held together by a small plastic cap.
  • Step 3 Examine the underside of the power lead for an arrow or dot. If one is present, the marking signifies the first pin. This must correspond with the first pin on the motherboard, which will also be indicated by an arrow, dot, or number. If no markings are present, the lead can be installed in either orientation.
  • Step 4 Place the lead over the power pins within the pin bank. The correct pins will be indicated by a diagram on the motherboard, or by a picture in your motherboard's instruction manual.
  • Step 5 Connect the power cable to the back of your computer, and turn the computer on.

    I need to know the sequence on how to connect my Power LED, Reset Switch, HDD LED, and M/B Switch up correctly. I have an MS-7142 VER:1 Can you help me?


    Hi carlmtclem, your not alone when it comes to hooking up the right led connector to the MSI MB. Firstly, you need to know what wire color is positive & which is negative. Most commonly the color white is ground/negative. Wire colors do vary from case to case. So look at your case led wires. Which ever color is common for each 2-pin connector, is negative. (Except the speaker wire).
    All other colors are positive.
    (The speaker wire color for negative is usually black & red is positive).
    Your MSI board has two separate sets of pins.
    JFP2 is used for the speaker only. Do not connect the power led there.

    4214cb1.jpg
    Pin one for JFP1 is shown in the manual. Pin 1 is positive & pin 3 is negitive for the HDD-LED, ECT.

    77ba70c.jpg
    Thats it.
    Need more information?
    Post here.
    Good luck carlmtclem!
    Thank you for using fixya.

    Lost in the wiring :(


    Hi bossman9628A, normally its the wire colors that messes everyone up when trying to connect the front case wires to the motherboard. The MSI RX480 Neo2-F, AKA MS-7151 MB is no different but does use a second set of pins just to help you get more confused.
    Gather up all your case wires. You'll notice there is one color that is common. Chances are that color is white & is being used for the ground wire. Other colors like blue, green, red, light blue, light green & light red ECT are used for positive. The speaker uses black for ground/negative.
    So looking at JFP1 at pin 1 is positive +. Pin 3, which is to the right of pin 1 is negative -.
    The manual does show you which pin is negative & which is positive. Pin 1 = (HD_LED_P). The _P stands for positive.
    Pin 3 = (HD_LED_N). The _N stands for negative. Do not connect the Power led at JFP2. Keep the power led connected at JFP1.
    Do connect the case speaker at JFP2. Most cases do use 2-pin connectors but others use 3 & 4 pin connectors. If your case is such you can remove a wire from a connector by using a decent needle. There is a small black tab that you can pull towards your self while pulling the wire out. You can than slide the wire back into the connector where you need it. You'll know the wire is inserted correctly because you'll hear or feel it snap into the connector. If by sme chance you get a led backwards, don't freak out. The leds use 5v DC. Just shut down the system & turn that led 180deg & reconnect it.

    Good luck bossman9628A!

    MSI K9VGM-V mother board case speaker connection


    Unless the manual states that there's a pin header for this, then it probably doesn't have it. To keep costs down and design simple, they probably eliminated it; not surprising, considering this is a microATX board, and many ATX PC's don't come with a case speaker at all these days. The good news is you probably wont need the case speaker, other than to troubleshoot odd startup issues. The bad news is you wont have any good way to troubleshoot odd startup issues... unless it uses the on-board sound card. Try hooking up headphones or speakers to it, and see if it outputs anything during startup. (It may only do so if POST fails, and only if it fails far enough into POST.) Not really anything that can be done, if it doesn't support it.
