Case Connections Question

[Tom Cat]

Noob question but I need help with case connections to the Mobo. This is a build for my dad and I never remembered these connections being hard on my personal build. Case is the q300l and the mobo is the b450m Ds3h. Thanks!

So what's problem ? Labels on the motherboard and connectors seem pretty much self-explanatory. If it doesn't work one way then flip it the other way but i think they should be label up.

[Tom Cat]

Right well, that's the thing, the labeling is very misleading and they can be flipped. I think one of them is supposed to be flipped.

Please note the HDD LED has a + and - lead, so I labeled them accordingly.

Same for Power LED + and -.

 

(If you're not color blind, this should help I hope  )

 

I would recheck the ports in the manual though. I would do it for you, but I don't know what mobo you have

if the motherboard labels look a little confusing, check your mobo manual. just plug it in to the corresponding headers. the switches don't matter which way you plug it in. if the LEDs don't light up, just flip it around.

LEDs have polarity. If you insert them the wrong way, the LED won't light up, but it won't be damaged. You can simply power off the PC, disconnect the wires, flip them and insert them back.

 

Switches (power sw, reset sw) don't have polarity. The buttons simply connect the two wires together, that's all a switch does. So you can put the two wires of a switch in any position.

 

Traditionally, the wires are inserted either with the printed text on the connector towards the top of the board.

It's the case with your picture, the printed text side of the connectors is towards the top of the motherboard. 

 

You have two power led portions, one with 2 pins and one with3 pins. In the past, a 3 pin version was used, because on some motherboards there was 2 color led used for power led ; you had the standard led (red) and you had an orange (or other color) for when PC is in sleep or stand-by mode.

Nowadays, it's only one led used so the middle pin in the 3 pin header (bottom right corner of the header) is no longer used. The bios may blink the led in sleep mode, or something like that.
