Wiring motherboard to a atx tower

The motherboard manual will give you a breakdown of the cast-to-motherboard connections for the board. They differ slightly from board to board, but the connections are almost always found at the bottom front corner of the motherboard. There will be connections for the hard drive LED, the power LED, the power switch, the reset switch, and on some, the speaker (optional). The power switch and the reset switch connectors , 2-pin plugs, are not polarized, meaning that they can be connected to their pins either way without issue. The Power and HDD LED plugs are polarized, as LEDs have a positive and negative. Get this plug backward and the LED won't work. These are also 2-pin plugs. The power LED usually has a green and white wire (Green is +) and the HDD is usually red and white (Red is +) . Some motherboards have color-coded pins -- DO NOT TRUST THEM IF YOU DON'T HAVE A MANUAL -- they are not always standardized. Some motherboards have small print on the board adjacent to the pins to identify them. You CAN trust these. Otherwise, go to the Motherboard manufacturers site and get the manual for the board. The model number is on the board and can be searched for. If the manufacturer's name is not obvious, Google the model number and it will usually lead you to the manufacturer.

Info to connect front panel leds

Each of the ends of the cables that lead to the LEDs should be labelled, e.g., 'PWR/power', 'RST/reset', 'SPK/speaker', 'HDLED/hard-drive-LED', 'PWRLED/power-LED'.

Connect each labelled connector to the labelled pins on the motherboard.

The set of pins for the power switch etc are on the front left corner of the motherboard if you are looking at the board with the ports/vga/keyboard to the back. Hope this helps.

KM18G pro motherboard power connection, reset sw, power sw, etc.


You can download the manual for your motherboard here.

Inside you will find information of where does each connector go. Each connector on the case has a marking on it (HDD, PWR, RST or similar) which stands for hard disk LED, power button, reset button and so on. Connect it to the right place, and problem is solved.

If you need any further assistance, feel free to ask.

If you have not removed the old motherboard from the case, then you can identify the various front panel connectors as you disconnect them and label them. Some front panel connectors have labels printed on the connectors which makes it easy for you to identify its purpose. If you have already removed the old motherboard then you will need to trace each of the leads to the front panel to see what they are connected to (eg. the LEDs and switches etc).
You will also need to identify on the new motherboard the various connectors for each function, eg power LED, hard drive LED, reset switch, power on switch, internal speaker etc. If you are lucky It may be printed on the motherboard, if not you will need to refer to the manual.
NOTE the LEDs are polarity sensitive, if the LED does not light, then swap the connector around the other way.

How to connect front pannel

How about a picture? Pg. 46 in your manual.
Need manual, download from Intel. (Click on link).

Intel RC440BX Specification
Pg. 46
Basic rules case wiring. The color black is considered ground -. Power wires + can be any other color including stripped wires. (This is standard but case Mfg change to their own specification).

Pin 1 is + power for LED Hard drive green LED, Pin 2 is -/ground for Hard drive LED.
(Pin 3 is + power for LED Hard drive yellow LED, Pin 4 is -/ground for Hard drive LED).(See more options on pg. 47).
Pin 5 is + power for case On/off button, Pin 6 is -/ground On/off button.
Pin 7 is + power for Reset Switch, Pin 8 is -/ground for Reset Switch.
Once positive & negative pins has been located each connector follows in suit.

The Intel RC440BX front case connector is in an odd location.
The user will find it hard to connect front case LED connectors while the board in installed into the case.

Good Luck!
