Re: short circuit in vcc and ground

Some questions first: Is this the same board mentioned in your other post? If so how did you decide that you have a short on your motherboard?

Do you have any user manual for front panel usb

(MSI PM8M-V H, is version 2.0 )

Hover your mouse cursor on the Download tab.
(Overview / Specification / Download / Support / etc.)

In the drop down list, click on - Manual
Under the subheading - Download, click on the blue -

[ This is a Zip file. A Zip file is a file that is compressed, to send easier. The above manual is for the M7104v1.0
It will work for the version 2.0 also.

You need a program to 'Unzip' it. (Decompress)
If WinZip is not working on your computer, go to 7-Zip, and download for free.
If you need guidance in downloading, and unzipping, post back in a Comment ]

There are two USB headers on the motherboard for the Front Panel,
JUSB1 and JUSB2. (Junction USB 1 and Junction USB 2)

Looking along the bottom of the motherboard, FROM the Right going towards the Left;

JFP1 header; (Front Panel main wires)
Header with 4 pins on the Top row, and 5 pins on the Bottom row.

JFP2 header; (Dual color Power On LED, and Speaker)
Header with 4 pins on the Top row, {Speaker}, and 3 pins on the Bottom row.

JUSB2 header.

JUSB1 header.

EACH USB header will support TWO USB ports in the Front Panel.
JUSB1 supports two,
JUSB2 supports two.

For each USB header there are 5 pins across the Top, 4 pins across the Bottom.
The pins are numbered EVEN across the Top, and ODD across the Bottom.

Starting from the LEFT side going across to the RIGHT side;
on the TOP row for JUSB2 and JUSB1;
Pins 2, 4, 6, 8 and 10.

Starting from the LEFT side going across to the RIGHT side;
on the BOTTOM row for JUSB1 and JUSB2;
Pins 1, 3, 5, and 7. There is NO pin 9.

A) Pin 2 is VCC
B) Pin 4 is USB1-
C) Pin 6 is USB1+
D) Pin 8 is Ground

E) Pin 10 is USBOC

Pin 10 is N/C -> Not Connected.
It is there, and Pin 9 is not there, to key which way a connector can go on. Only ONE way.

F) Pin 1 is VCC
G) Pin 3 is USB0-
H) Pin 5 is USB0+
I) Pin 7 is Ground

There is NO pin 9.

(The USB technology used is USB 2.0)

Let's read together,
Under - USB pinout signals;

"USB is a serial bus. It uses 4 shielded wires: two for power (+5v & GND) and two for differential data signals (labeled as D+ and D- in pinout). NRZI (Non Return to Zero Invert) encoding scheme used to send data with a sync field to synchronise the host, and receiver clocks. In USB data cable Data+ and Data- signals are transmitted on a twisted pair. No termination needed. Half-duplex differential signaling helps to combat the effects of electromagnetic noise on longer lines. Contrary to popular belief, D+ and D- operate together; they are not separate simplex connections."

See the USB examples in the link above, where it labels the contact pins?
The MALE connectors are shown on the Left side.
The FEMALE connectors are shown on the Right side.

Your USB ports will be FEMALE, on the Front Panel.
They are also the A style. USB A style. The Top example to the Right.

Just noting the following in case for some reason, the wires coming from those contact pins in the female USB connector, are not color coded correctly;

Even after you have the wires sorted out, as to which contact pins they go to, DOUBLE-check again. Do NOT just go by the color code of the wires.

You do NOT want to accidentally connect the +5 Volts (VCC), to the Ground!

Explaining further;
You connect the VCC wire, (Red), of the USB port in the Front Panel, to the Ground pin on the USB header on the motherboard.

(Which means the Ground wire of the USB port, (Black), will probably also be connected to the VCC pin, on the USB header of the motherboard)

Zzzzzzap! There goes your front USB ports. Both USB front panel headers on the motherboard, will be DONE!

Make sure!

Going on;
1) VCC or Vcc, goes back relating to Transistor technology.
Just think of it as the Positive, or power wire.
It is.
It is 5 Volts DC.

2) GND is Ground. It's a DC circuit, and you have a Positive, and a Negative, or Ground.

3) USB1-
That is -> Data-

USB0 is for one USB port in the Front Panel.
USB1 is for another USB port in the Front Panel.

[ Each USB header on the motherboard can be connected, to TWO USB ports on the Front Panel.
Therefore for the two JUSB1 and JUSB2, you can connect Four USB ports in the Front Panel ]

Data- on one USB port in the Front Panel, goes to USB0-

Data- on the other USB port in the Front Panel, goes to USB1-

4) Data+
Same thing.
Data+ on one of the USB ports in the Front Panel, goes to USB0+
Data+ on the other USB port in the Front Panel, goes to USB1+

EACH side of JUSB1 and JUSB2, will support one USB port on the Front Panel.
Two sides per JUSB1 and JUSB2 = 4 USB ports on the Front Panel.

For additional questions, or clarification to anything I have stated above, please post in a Comment.

I need help with connecting my case wires to the motherboard

those wires are for the USB not audio,the meaning of the
writing no the wires are:
vcc=5 volts, -D=data negative, +D= data positive,GND=ground.
look in the manual for usb connection, if the mainboard has the header connection for them connect the wires to it if not just leave them out, secure them out of the way.

Need SPDIF pinouts identified.

When looking at the board, bottom towards you assuming that the 3 pins are parallel to the pci/e slots, the left pin should be the +5V vcc the middle pin is the spdif out and the right pin is the ground. Also the 3 pins are probably not exactly the same distance from each other (equally spaced) the 2 pins that are closest together are the spdif and the ground, spdif is always the middle pin. This info is based on 2 different asus motherboard install guides. I hope this helps you.

Since your using P4M800PRO-M478, I recommend you to read the manual to refer about the pinouts for all the connectors for your motherboard.

Just in case you don't have the manual, here the link for you to download.

Don't forget to rate my solution, thanks!!

Asus k8v se data-2 data+2 ground and vcc wires

You can download the manual from this location


Go to page 1-21 and see the extra USB connectors. If you are talking about your wires coming out from your case and used for a USB port like the one in the front, you should connect them to any of the 4 available USB channel following the polarity. For example connect your Vcc to USB+5V, groung to GND, data-2 to USB_P8- and data+2 to USB_P8+



Let me know if you need more help
