You'll need good light and a steady hand.....locate on the motherboard a set of between 10 and 18 pins (2 rows) look at the board either directly below or above the pins to find a kind of key or map as to where the pins are located....they'll be in abreviated form and should indicate where and which row the connectors should be located

Front panel connections


I don't find the Front Panel header pinout online, nor do I have an MSI MS-5191 in the shop.

I would suggest using one the LED lights with two wires.
(3-wire is a dual color LED)

There are two rows of pins. Usually the Power On switch, Power On LED, and Speaker; are on the same row.
HarDDrive activity LED, and Reset Switch are on the opposite row.

Speaker has 4-pins designated for it. All the others use 2-pins.
(Unless the PWR ON LED is a dual color jobbie)

Touch two pins next to each other, in the same row; with the 2-wire LED.
Start with finding the Power On switch first.

Usually the top row 1st two pins are Power On LED (Light)
Next in line are the 2 pins for the Power On switch.
Bottom row 1st two pins are usually HarDDrive activity LED (light)
Next 2-pins are usually Reset switch.

May not apply to a motherboard old enough to use a Socket 7 processor socket.
There may be 18 to 20-pins.
Bear in mind that many are not used, and probably 4 are for an internal speaker, for hearing BIOS Beep Codes.
May be two separate Front Panel headers.

Once you find the two contact pins in the Front Panel header, for the Power On switch; I would put the Power On switch wires on.
The small pin connector on the wire/s, will keep you from accidentally touching these two pins again, when the computer is on.

Now you have the two pins for the Power On switch, and the computer is running; then keep touching 2-pins at a time with the LED. (Light Emitting Diode)

LED stays on? You have the Power On LED (Light) pins.
LED blinks? HarDDrive activity LED (light) pins.
Computer restarts? Reset switch pins.

Look for abbreviations near the pins in the Front panel header.

PWR, Pwr, Pwr On, Sw, and SW; are just some of the abbreviations for the Power On switch.

HDD LED, and HDD are two for the HarDDrive activity LED. (Light)
(If it states HDD SW it is the Power On switch. Weird old way of marking)

RST, Reset, and RSW, are for the Reset Switch.
(Reset Button)

If you see 4 pins marked with a bracket ( [ -> Turn so it's horizontal), these are for the internal speaker.

Type MSI front panel connector in your search bar, and look at -> images. See if you can find an image of your MSI Front Panel header pinout.

You can bet MSI carried out that Front Panel header pinout, on other MSI motherboards, besides the MS-5191.

The MSI MS-5191 may have been a motherboard made by MSI, especially for a pre-built computer manufacturer, and not listed on their website as an OEM motherboard.
(Original Equipment Manufacturer)

Won't have the Front Panel header pinout, listed on MSI's support website. (Doesn't)
But you can bet there IS an OEM motherboard made by MSI, that the Front Panel header DOES match.

May be different expansion slots, or motherboard chipset, or whatever; but the same Front Panel header pinout.

I have a GA-81865GME-775-RH motherboard, which i put into my box, made all the connections, but have no power once I switch the box on. I suspect it has something to do with the wiring loom running from...


Hello julian_ad681

I will tell you how wire your case front panel, but before that lets test the motherboard to make sure the problem is not the board itself.

Remove all the wire connections to the front panel.

Turn the power on and with a small screw driver or anything that is metal short (touch) the two pins that are the PWR SW. (look at the list of pins I have put at the end)

If the computer turns on then it means the board is ok.

The following information is also availabe in the motherboard manual available from the gogabyte web site download section

On the motherboard next to the battery is the front panel header pins. it looks like

0 0 0 0 0 0 0 0 i also write them as numbers as well to make it easy for you)
0 0 0 0 0

1 2 3 4 0 0 0 0
5 6 7 8

1 and 2 are message LED. you don't need any connection to this.
3 and 4 are the power switch connections no polarity, just connect the wires
5 and 6 are the hard disk LED. 5 is the positive side (usually red)
7 and 8 are the reset switch. no polarity, just connect the wires.
Next to the message LED there is a three pin connection. This is for the power LED.


hope this has helped you.

I have 3 wires on my pc and i dont know where to connect them on my motherbaord - the wires have writen on them "HDD LED" "PWR LED" "PWR S/W" can any1 help me?


Hi Dan,
The wires are from the front panel. HDD LED which causes an led (usually red) light to turn on when the Hard Drive is active. The PWR LED turns on an LED light (usually green) when you turn on your computer. The PWR S/W turns on your computer when you press the on button of your computer. The front panel connector riser is usually located on the bottom right of your computer. They fit on little pins. Unfortunately there is no standard, so connections vary. Sometimes the pins are labeled on the motherboard. . Check your manual. For more info do a google search for "Motherboard front panel connectors". Hank

I have an 945gzt-m v 1.0 and dont know were the pwr sw wire goes


Yes.
First, let's orient the view of the motherboard, so we are both looking at it the same way.
The processor is at the top middle, and the Front panel header, is to the very bottom right hand corner.
Right next to the motherboard mounting hole.
The Front Panel header goes across the bottom edge of the motherboard, lengthwise.

Looking at the top row of pins on the Front Panel header, No.2 Pin is at the far left. Pins 2, 4, 6, 8 and 10, go across the top.

Looking at the bottom row, No. 1 Pin is at the far left. Pins 1, 3, 5, 7, and 9, go across the bottom.

The power switch wires go to Pins 6 and 8.
The HDD LED wires go to Pins 1 and 3.
The power LED wires go to Pins 2 and 4.

On the power switch wires, the Positive (+) wire goes to Pin 6. Just in case this wire is marked.
(Doesn't really matter which way it goes, because it's a switch!)

On the HDD LED wires, the Positive (+) wires goes to Pin 1.

On the power LED wires, the Positive (+) wire goes to Pin 6.

translated this is top row left to right ...... power led, power switch no connection

Bottom row is left to right........ hard drive, reset, no connection

Note: not all computer cases have a reset button, also the connectors for power led and hard drive produce a light, if the light does not show, power off the pc swithc the cable rooun 180deg on the connector pins and reconnect.

Gigabyte GA-8INXP Motherboard Problem- front connector pins


If the wires from the reset switch is white/blue the blue wire is positive, Hdd red/white red is positive power Green/white Green is positive etc. The wires on the speaker connector will be red/black/black/white - red is positive. The colored wire is always positive. On all GA mb's the positive connection is always towards the back of the MB and are marked with a + on the base of the pin as you can see on the photo. Hope this help.
