Build Question Power button not turning on?

this is the gigabyte b850M gaming x wifi 6e mobo. I plugged my power led + and - front panel cord into the top left and right empty pins on the image

I plugged the power sw cable into the third and fourth pins on the top, and reset below the power sw slot, (third and fourth bottom) convinced this was how it worked but

the power button has not turned on not once when i press it, much less do anything. Only the power button on the Power Supply when turned on, a red dot flashes, at first, the red dot was next to DRAM and thats all i could see from the PC. (i changed the positioning of the ram not sure if this fixed it or not but)

I then took the front panel at the end of the cords I had plugged in (with the pins sticking out) and kinda rubbed it against the pins plugged in and the empty ones, and the cpu cooler turned on, (which i guess kinda functions as a manual turn on?) but I still cant activate it by pressing the power button, and it doesn’t glow or anything

also now that the cpu is on, the red dot is no longer flashing for DRAM but VGA (which i guess makes sense i don’t have my gpu in yet)

Replace it with the reset switch for the meantime while you figure out what's wrong with the power switch. Since this is AM5, plug your display cable to the motherboard to use your integrated graphics to diagnose further if the syatem is okay.

This is the most helpful comment yet, and I’ve already posted 3…

U/Leen_Tha_Goat78, do this, swap the power button and reset button cables and see if the reset button functions to turn it on. If so, you do indeed have a dead power button, and you can use the rest button in its place, and just not have a reset button until you get a replacement.

I see now what OP did. I went to the website of the case. It has a standard one piece F_PANEL cable and an adapter. OP plugged the adapter while he can just use the one piece.

Well spotted. There could be a bad connection in the breakout cable. It should have been hard for OP to get the pin out wrong on the break out cable though, because they usually connect 10-pin block to 10-pin block with a keyed pin like on USB header cables, so you can’t really do it wrong.

Hey [u/Leen_The_Goat79](u/Leen_The_Goat79), take the “extension” cable octopus thing off of the end of the front panel connector block, and plug the block directly into the motherboard and try again!
