Motherboard Cable Setup

By BorgInva ·
I am building a new PC and it is true I am not so much up there with hardware knowledge. I have a new ECS PF21 Extreme Motherboard.

The power is setup like so:
10 9 8 7 6 (no pin on 6)
1 2 3 4 5

1 > HD_LED_P
2 > HD_LED_N
3 > RST_SW_N
4 > RST_SW_P
5 > RSVD
6 > NC (no pin)
7 > PWR_SW_N
8 > PWR_SW_P

I have 5 connectors from the chassis' front (with cable colors):
-P LED (white)
+P LED (green)
HDD LED (yellow/white)
RESET (white/blue)
POWER (orange/white)


The motherboard has 2 connectors called USB 3 and 4. The pin layouts are:

10 9 8 7 6
1 2 3 4 5 (no pin on 5)

1 > USB DUAL VCC (pin1)
2 > USBP4-
3 > USBP4+
5 > KEY (no pin)
6 > USBOC45#
8 > USBP5+
9 > USBP5-

The chassis' front USB ports are:
1 VCC = Power for port1
1 -D = negative signal for port1
1 +D = positive signal for port1
1 Ground
2 VCC = power port2
2 -D = negative signal for port2
2 +D = positive signal for port2
2 Ground

What gets plugged into where? I have checked the docs for both products and found nothing. Wrote to both companies, and of course, got nothing back.

Thank you for your help.

I have that manual, and I listed their pins above, as you cna see. They are no help.
For example, taking from the above,
Where do these go?
-P LED (white)
+P LED (green)
And for this
POWER (orange/white)
whihc is negative na dpostivie (this is a 2 pin connector).

When I mentioned above wires with 2 colors, like the power with orange and white I think, they are double pin connectors having 2 seperate wires, not one connector with a wire in 2 colors. You know what I mean?
we are also going to guess white means negative on the wires, but it does not help us solve all the connecting connectors.
?????? Connecting connectors? Hmmm....

It is not that I do not want to do the whole trial and error bit, but I am afriad of blowing out these new LEDs or USB ports by having power and stuff on the wrong pins, you know?

Looking at the manual will have a description of the connector,understanding what color at palce on which pin is usually by trial,you then note the connector placement.

Using a small flash light you can see the connector labeled on the board.

You can place the connectors on the designated place and check what lights come on when you boot,you cna then swith the connectors to get them orientated correctly

The Pin numbers usually are designated even on one side odd on the other

See TR for previous post about the connector placement

Taking a chane on putting a negative connector on a positive pin, I am afraid to hook this up and blown up somehting on the MB, or even the USB or power stuff. I spent too much money for a trial by error gig having this poor directions. Already the MB people said they can not help. Same with the chassis people. Unbelieveable. They made this stuff and can not help me make sure not to fuze something out?
As for putting connectors on the board, let us take power, okay? Wires are a double pin conenctor: POWER (orange/white). Supposed to go on these pins, yes?
7 > PWR_SW_N
8 > PWR_SW_P
Well, one is negative, supposedly 8, and positive is 7. The PC powers on however I connect the power connector. Whether the wwhite wire is on 7 or 7. That can not be right, can it? Is that not safe to have the PC powered on the wrong polarity?
The pin numbers on the board give some indication, but not the chassis power or USB wires, mainly for the double wired ones.

Normally white is -ve & otehr colour is +ve
So1 > HD_LED_P is hdd yellow PIN 1

-D = negative signal for port1=USBP-
1 +D = positive signal for port1> USBP4+

1 Ground IS GROUND

Very close to what we figured out. So I will throw you the points. I thought I closed this question back in April.....
