Motherboard Power/Reset Button & LED Installation

[Kaisa_Sosa]

I'm having a little trouble installing the wires from my power button and reset button. The LED wires from the front of my case have been installed easily due to the been labeled + and -however the power and reset buttons have different colour wires to the LED and therefore I'm a little unsure.

The pins are like this:

(pwrled +) - (pwrled -) - (pwrbtn) - (pwnbtn) - NO PIN
(hddled +) - (hddled -) - (RESET) - (RESET) - NOT USED

And the colour of the wires are:

pwrled + = green
pwrled - = white
pwrbtn = unknown (either black or green)
ground = unknown (either black or green)
hddled + = unknown (either red or white)
hddled - = unknown(either red or white)
reset = unknown (either red or black)
reset = unknown (either red or black)

Is anyone able to help with the unknown ones?

Polarity does not matter on power and reset wires (switches).

Polarity does not matter on power and reset wires (switches).

But what about the HDDLED + & - because they are 1 wire and one is red; the other is white? Does that matter?

Red is usually positive: red=positive
Black is usually ground and is considered negative: black=ground=negative

The only place this is actually important is where it connects to an led. Since your pwrled colors are neither red nor black it's impossible to tell which is which by their color. The hddled has a red lead so consider that positive. that leaves white being negative. I'm guessing that applies to the pwrled also. So white would be negative leaving green to be positive.

It won't hurt anything to hook up either of those connectors backwards so try it one way and if it doesn't work reverse it.

alexoiu is right on the other connectors.

With leds it does matter. But even if let's say you connect them wrongly, just switch the wires and led will work.

Okay thanks guys! And BTW for my grpahics card do I use one PCI-E wire or two?

 

[alexoiu]

What model? If 2 PCie power connectors, then yes, 2 cables.

 

[Kaisa_Sosa]

It's a GTX 970 and it has 2 6 pin PCI connectors

 

[alexoiu]

Connect 2 x 6 pin PCIe cables to it.

from one slot on my PSU or two slots?

 

[alexoiu]

Better 2 slots.
