Question Cant connect case cables to mobo

[AsCeDaNtV]

I just built my new computer and I can't connect my case cables to the motherboard front panel (Gigabyte b450M DS3H) tried everything still can't figure out the correct order I am only given this picture.I know very little about pc building as you propably realised so I 'd prefer a simple answer.

Really isn't a 'simple' answer. You need to read the labels on the connectors for what they are and positive/negative. If they aren't labeled trace them back to their components at the front of the case. You need to identify the pins on the motherboard they correspond to and get positive/negative correct on all the LEDs.

All the information about the pins on the motherboard should be in the motherboard manual. You just need to orient yourself to the diagram and the physical board.

USB 3.0 connector should be obvious, USB 2.0 connectors are usually keyed with one out of 10 pins missing, match up the missing pins.

There really isn't a completely typical standard, a failing of the industry to be sure.

I agree there isn't a simple answer. Case connectors are the most confusing.

Page 16 of your owner's manual details where to plug in your front panel connectors (power switch and others)

Pay attention to the + and - on the front panel connectors. If you connect them incorrectly, it won't work.

HD audio and USB are labeled on the motherboard aswell.

In the bottom right of your motherboard, you will see pins like this. Connect the switches like shown. It is confusing, but once its done you won't have to do it again.

I do exactly as you say but some of the cables I got don't appear on the manual for example HDD Led I connected the others correctly but my computer won't start

Not all have to be connected for it to start. If your power switch is connected properly it should start.
Try bridging the power switch pins with a screwdriver. Make sure your PSU is switched on.
If it still doesn't work, the issue lies elsewhere.
