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.

Regards,

Woule like the pin location for power & leds on F-P1 socket


The corner of the motherboard "diagonally-opposite" of the keyboard/mouse PS/2-port connectors has a grid of gold pins. One pair of pins is labelled 'PWR'.
One pair of pins is labelled 'RST SW' ("Reset Switch").
Another pair of pins is labelled 'PWR LED'.
Another pair of pins is labelled 'HDD LED'.

Hmmm.... mainly you have:
-20 or 24-pins connector, that is unique and goes directly to motherboard (powers motherboard and its components)
-4 or 8-pins connector that powers CPU
-the rest would be connectors for ROM (CD/DVD/BlueRay) and HDD devices (there are: molex and sata power conectors)

If you totaly unshure, there is manual:

Nothing happens when I press the power button. No


What about the power supply? I bet it's supply's issue. Otherwise make sure that PWR button wires are connected properly and to the correct terminals of the motherboard

Two sets of power leads to motherboard from pwr pk, 1 x 20 pin and a 4 pin, when the 4 pin isn't attached to the 8s651mp-rz motherboard the fans spin, the mother board light comes on, but then does...


The 4 pin connector is required as it provides the power for the CPU to run. if nothing is happening with the 4 pin connector plugged in then there is a problem. You need to make sure that you Power Supply can supply enough power for what you are connecting to it (400W would be the bare minimum with no high end video card, 500W would be recommended). You also need to make sure that the Power Supply is connected properly because some Power Supplies from pre-built systems from companies like Dell are wired differently than the standard power supplies. The only other likely problem is that there is a short on the motherboard either from the mounting of the motherboard in the case or from something on the motherboard being bad. Make sure there is no metal touching the motherboard except at the holes used for mounting.
