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.

Hi Greeneyedbj,

pcsyke_138.jpg

The image above has the following for your I/O connectors.
1. Three usb headers up to 6 additional devices, most casing can support 2-4 pins. 2. Front Audio Connector. 3. Front Panel Connector. Power Sw, Reset Sw, Powed Led, HDD Led

Branded casing has the following I/O connectors.
1. Esata 2. Firewire (Dont use the USB headers, firewire use a different pin-layout) 3. Chassis Intrusion Alarm Header.

Hopefully this information helps.

Hello Phenom, Hi.... to properly run/test a motherboard, you need to make sure this parts are good with no doubt functioning. 1. the power supply, 2. Memory, 3. keyboard, 4. Processor with FAN 5. PC speaker(built on-board or the thumb speaker) and 6. monitor How to test. First remove all motherboard connections. Now reconnect the following. 1. make sure that the power supply 20/24 pin is connected properly to the motherboard (and please test this power supply before making connections. To test independently short green wire to ground and plug the unit. you should see the fan spin) 2. make sure that the 4 pin 12volt power connector is also plug in nice and tight. 3. clean the memory slot using a clean paint brush and the module (DDR/2) terminals (the contacts) using an eraser, 4. connect the keyboard, 5. make sure there is a PC speaker connected. 6. connect the power switch of the front panel, 7. Connect a monitor on the VGA port 8. Power on the PC. 8. Look at the keyboard lights 3 LED momentarily. num lock + caps lock + scroll lock and after several seconds 1 LED light, num lock only. If you reach this part you should also hear a beep. then the POST will appear. If you don't reach this part, start again from the top. do this several times. Still no response? you motherboard is bad.

Runs to the front-panel LED that lights-up whenever the Hard Disk Drive is being used.

Runs to the "reset" button on the front panel.

Very briefly touch a metal-tip screwdriver between these 2 pins.
If the computer powers-on, you've found the "power" connector.

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!

Swapped mother board


Hi Paul,
see page 8 number 15 for location. Than see page 19, System Panel Header in your manual.
The basic wire color's for positive are red, blue, green & can also be light blue, light green, light red.
Negative wires are usually white or black. Case wire colors do vary from case to case.
To see pin one shown on page 19, (positive + for hard drive led = HDLED+). Bottom row farthest pin to the left of set. Pin two is above pin one. Pin two is, PLED+ (known as power led). Pin 3 is to the right of pin one & is HDLED- (Hard drive led, negative). Pin 4 is above pin 3 & is also PLED-, (Negative for power led). ECT!
6781222.jpg If your new case has an internal speaker (Used for P.O.S.T, power on self test). This would connect to, Chassis Speaker Header located on page 8, number 16. Again, normally only two wires are used across the 4-pin connector. (One at each end of the connector).

To see ASRock's main site for the 775VM800 motherboard click this link:
http://www.asrock.com/mb/overview.asp?Model=775VM800&s=

Good luck Paul!
Run into a snag, just post the issue here.

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.
