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 an MS-7502VER:1.2 motherboard and i cannot find wher to plug the power switch into


Hi scouts692

The Front Panel Header Pin arrangement for this motherboard is unusual, in that the header only appears to have 8 pins in a single column rather 2 parallel columns of 6 Pins with 1 blank, as most conventional motherboards do.

Pin 1 is POWER SWITCH orange or red (PWR SW 1)
Pin 2 is POWER SWITCH white or black (PWR SW 2)
Pin 3 is POWER LAD + (PWR LED -)
Pin 4 is POWER LED - (PWR LED +)
Pin 5 is HARD DRIVE LED - (HD LED -)
Pin 6 is HARD DRIVE LED + (HD LED +)
Pin 7 is RESET SWITCH blue or green (RST SW/RST 1)
Pin 8 is RESET SWITCH white or black (RST SW/RST 2)

Please refer to a PDF of the Motherboard Manual for additional information about the setup of this motherboard (the relevant page for the Front Panel Header is page 17/Section 2-13)

hope this helps.

Installed mother to new tower case and pwr sw | hd led | reset | power led connecting to my board is the Intel dq67sw 155 matx motherboard need accurate dir to connect these please help


info found at http://downloadmirror.intel.com/19707/eng/DQ67SW_ProductGuide01_English.pdf
Front Panel Header Pin info for DQ67SW. They should be color coded too. 1 Hard disk LED + orange
2 Power LED+ green
3 Hard disk LED - orange
4 Power LED- green 5 Reset Switch - blue
6 Power switch + red
7 Reset switch + blue 8 Power switch - red
9 Power Out (do not use)
10 No pin
NOTE When connecting individual wires from your chassis front panel to the front panel header, be sure to observe the connection polarity. Positive wires are usually solid color and negative wires are usually white or striped.
There is also an alternative pin header if you have a power wire that uses a 3 pin connector instead of a 2 pin connector. It is the 3 pins just past pin 9, and it should be missing the pin in the middle of the 3 pin block. The pin closest to pin 9 is the power led + and the furthest from pin 9 is the power led -.
if you need clarification, check out page 50 of the manual posted above at intel.com

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.

How do i wire-up the: ( eg. power l.e.d., HD led, reset led ect. to the board


The various wires from the case front panel should be labeled to indicate power LED, HD LED, etc.
The motherboard front panel jumper pins should be grouped together and the pins should be labeled to indicate PWR, HD. RST etc.
You can go to the motherboard manufacture's WEB site to download a diagram of your model motherboard and it will show all the locations of the connecting pins.

Front panel to motherboard, ASRock P4i65G, connections


the power switch is on the 3 and 4 pins....the 7 and 8 pin are the reset pins. Trying it on wrong pins just won't startup the board but won't short circuit anything.

Wiring color code sequence for the pins to the front system panel for an asrock p4i65g motherboard. There are 4 double pin connectors. Jim/Sudbury


Can't say what the colours on your case wires are because they do vary but they should be marked up PWR SW (or PWR BTN), HD LED, etc.
Looking at the pin layout there should be a row of four with the pin on the far right missing and underneath a row of five with the last one on the far right being unused.

12 3 4
OOOO
5 6 7 8 9
OOOOO Pins 3 and 4 are PWR. Pins1 and 2 are PWR LED.
5 & 6 are Hard drive and 7&8 are reset

New motherboard


You don't say what case you are using. If it is proprietary and the front panel header is all in one connector, you can carefully back the connector pins out of the block using precision screwdrivers. I keep a bunch of two pin connectors from junked machines so I can create individual connector sets when changing motherboards (eg, PWR SW, PWR LED, HDD LED and RESET). This also requires that you know the pinouts of both the old board and the new one so you can get everything connected properly.

Very doubtful you will ever find an adapter to change from one front panel block to another.

The 9-pin connector probably uses a spacer pin between the legs of the PWR LED, while it seems the 6-pin does not have RESET.
