Subject: Power Button Cable Location on Motherboard
Date Posted: 23 Nov 2017 at 1:26pm
" rel="nofollow - On the Asrock AB350 Gaming-ITX/ac I want to make sure that I connect the Reset and Power Button to the correct jumpers on the motherboard. The Powerbutton cable doesn't appear to have a Plus and Minus side to the cable. When connecting the cable to the motherboard, should the cable be straddled top and bottom or right and left? Same question for the Reset cable should it be connected top and bottom or right and left on the motherboard?

to be technical
it dosnt matter on power or resets
all they do is make the circuit when pressed
the plus and minus matter on the led connectors though as they are diodes and thus wont work the wrong way round
as for which ground to use
follow the orientation of the leds already inserted eg along the row not crossing the row(it dosnt matter really but looks neater)
and the odd pin on the end a ground can be ignored

Just to be clear here. There are two rows and five columns. Should I place the power and reset buttons cables on columns 4 and 5 respectively and NOT across pins in the same row.

The pins boxed in red are where the power switch connects. The reset switch connects to the pins to the right and up one pin, directly under the SATA port. Beneath the power switch (in the image) is where the power LED connects and directly to the right of it is the HDD activity LED connector. There should be a gap of 1 pin between the reset switch and the HDD activity LED.
I hope that makes things clear, it is all marked on the board but it's hard to read given the black on black text.

Oh and if there is label text on your connectors, the label side always faces to the right (referencing the image). This only matters for the LEDs, they will not light up if the polarity is wrong. For the switches, as datonyb stated, there is no polarity so it doesn't matter.

looking at the picture and the motherboard manual its two columns and 5 rows

Thanks for the follow-up. I'm waiting for a board replacement and will ensure that my pins are connected per your instructions. I wish the manual was a bit clearer on this.

I find as a general rule that MB header cables that form the earth/ground/negative are either white or carry a white stripe..

The diagram above that is shown in red appears to be in conflict with the documentation on page 29 of the manual. I would bet that the placement of my header cables is the root cause of all of the issues that I have been having with this computer build. I am currently dealing with a power recycle issue that may be related to the bumbling that I appear to be doing with these header cables.
The "pins boxed in red are where the power switch connects." There are two ground connections in one column (5 possible connections) and one ground connection in the other column (4 possible connections).
The power switch looks like it can be connected within the same column as the diagram above describes or it can be connected across two columns. What is NOT clear is what ground connection is left OPEN. The documentation on pg. 29 does not clearly spell out where the reset and power cables go as there is no plus or minus designation on these cables.
Believe me I'm not trying to be difficult here, but just trying to get clarification on a build that I should have had completed over a week ago.

Your confusion is understandable, since the system panel header is usually oriented the long way horizontally, rather than vertically as it is on an ITX board.
Picture from the manual:
For this board, the power button connector from the PC chassis is connected to the two pins you have circled in red, above in your picture. That is, the GND (ground) pin for the PWRBTN pin is directly above it.
NONE of the connectors from the PC case should be connected with their two pins horizontally on this header, they should all be connected vertically.
The ground or negative (-) pins for each of the four connections is the negative/- pin directly above each type of connection.
The PLED and HDLED + and - connections are oriented vertically in the picture. It would be inconsistent to then have the PWRBTN and RESET connections oriented horizontally on this connector. Which is why they aren't oriented horizontally.
Regarding which wire from the PC case is + or -/ground, that depends upon the PC case manufacture. Some PC cases put a + and - on the plastic connector itself. Others color code the wires, as said above. It is true that the negative/ground wire will normally have a while line or white dashes on it. If that is not the situation with your PC case, that is beyond the control of a mother board manufacture.

Do I need to open up a ticket with Asrock to get a "picture" diagramming where each cable should go or should I continue to try all variations with the potential of damaging my motherboard? This lack of clarity may be the reason why nothing would power up at all with my first motherboard. My second motherboard is exhibiting a power recycle loop. I have elected to get a new CPU and Memory sticks to rule out these components, but this all may be pilot error because I can't figure out where some stupid cables should be connected.

So you find my description inadequate? You cannot understand it at all? To the extent that you find it completely useless?

Your explanation was clear but non-intuitive. Why did Asrock change the orientation of the Reset and Power Button cables in respect to the PLED and HLED cables? I don't think I've ever done this in any other motherboard. I have built two Asus and One MSI motherboard and their manuals are clearer and the front panel pin orientation doesn't change up as you connect the other cables.

Thank you Wussery I had the same question about the Power and reset connectors. The picture from ASRock cleared up the confusion.
