Power Button Isn’t a Power Button (It Changes Case Lights)?

[JudithWright]

Just finished a Ryzen build using the Apevia Destiny Mid-Tower Case:

There is a problem with the Front Panel connectors, which I have never seen before.

 

Here are the Front Panel Connectors coming from the case:

 

HDD LED

Power LED (One Positive, One Negative)

LED SW

 

 

There is no Reset cable (which is fine, because there is no Reset Button on the Front Panel).

 

Main Problem:

 

There is no Power Switch cable for the Front Panel.

 

 

PC Behavior:

 

I plugged in the HDD LED and POWER LED cables in their normal positions, and left the LED SW cable disconnected.

 

When pressing the Power Button on the Front Panel, nothing happens.

 

I used a screwdriver to jump the Power Switch pins on the motherboard, and the system turns on normally.

 

 

When the system is powered-on, the Power Button on the Apevia Destiny actually changes the color of the Fan Lights.

 

Very strange, and I have never seen this before.

 

I just want to be able to plug everything in, and run the system normally.  

 

 

 

My plan:

 

I was going to plug-in the Power LED cables into the POWER SWITCH pins on the motherboard, and then plug-in the LED SW cable (from the case) into the POWER LED pins on the motherboard.

 

 

Are there any obvious mistakes here?  

 

Would this damage the motherboard (if so, why)?

Yes, don't switch around pinouts. Putting a switch across an LED output is a dead short when pressed and may break something (if the board isn't designed to prevent it). My guess is that LED_SW is actually the PWR_SW with extra features, but you'll have to experiment.

That sounds the wrong way around.

 

Plug the power LED cables into the power LED pins and the LED SW (switch) cables into the power switch pins.

Thanks for your quick response, but I got impatient and did this anyway (before I saw your post).

 

Do you think I damaged anything?

 

Motherboard is the MSI ProSeries B450M PRO-VDH Max

Probably not, but the only way to tell is to connect an LED and find out.

Okay, I plugged in the LED_SW into the Power Switch pins - and the other cables are plugged-in normally.

 

The system only turns on when I press the LED Button on the Apevia Case.

 

The Power Button changes the Fan colors.

 

 

I other words, this seems to be completely reversed.

 

 

Everything else does see to be working normally:  the system booted into BIOS and the Case Fan lights can be changed normally (does this mean nothing was damaged with the motherboard)?

Did you connect PWR_SW to the LED hub? Connect LED_SW to the LED hub and PWR_SW to the motherboard.
