Installing the case front panel connectors to the motherboard is not hard to do, but might take you a few minutes or more to figure out which exact motherboard headers (just a fancy word for connections) you need to plug your front panel connectors into as every case and motherboard will be slightly different. In this guide we'll give you some tips on how to do this, with photo examples from our own build example. This guide is part of our main How to Assemble a PC tutorial, so see that article for all the other before and after steps.
Before we get into how to connect motherboard front panel connectors, let's take a step back for a sec and cover the absolute basics for anyone wondering what the front panel connectors on a motherboard are for. The front panel of your computer case will have a number of easy-access features such as USB and audio ports, as well as basic functions for your system like the power-on and off buttons.
A typical case will have the following front panel features:
Some cases might have some fancier features on the front panel, but you must ensure your motherboard actually supports all the front-panel features of your particular case if you want to be able to use them all. This is something to consider when choosing a motherboard for your computer case, especially if you're using a high-end case with fancy features.
The front panel features of a case must be plugged directly into the motherboard, which is what this guide will explain. Before learning how to connect motherboard front panel connectors though, you want to have finished installing your motherboard securely into your case. Done that? Let's get into it.
Your case will have pre-attached front panel cables like these, which plug into the motherboard
Before you connect front panel connectors to the motherboard, you'll want to first locate where all the cables need to plug in on your motherboard. It might not be immediately apparent where to connect the front panel connectors to your motherboard, and the way they are labelled varies from board to board. This is one step of building a PC that you definitely want to consult your (motherboard) manual for.
Below is what our particular MSI motherboard for our example build includes in the manual on this, but go and find this section in your own manual to know exactly where to connect the front panel connectors for your particular motherboard and case. Our motherboard didn't come with a full manual, and only a quick installation guide which didn't cover how to connect front panel connectors, so we had to download the full manual from the manufacturer's website. You may have to do the same if there's no information on front panel connections in the manual you had shipped out.

As well as first finding out where the cables must go, before you actually connect the motherboard front panel connectors you also want to think through a little basic cable management. The aim is to minimize any loose/excess front-panel cables that hover around your motherboard and the middle inside area of your case. This will promote better airflow, keep your build looking neat, and make components easier to access now and later on.
By knowing exactly where everything plugs in and pretending to connect everything, you get a sense of how loose the cables will be once they're plugged in and can therefore plan ahead to tuck the cables away more neatly somehow.
If a certain front panel connection will seem quite loose once connected, try to thread/route the cables through any holes available in the back (as in the rear side panel) of your case which will help you avoid having loose cables that hangs around in the middle of your case/motherboard area.
Most cases will have these cable management holes on the back which are designed for this exact purpose. Our case has some holes, and so we've threaded the front panel connector cables through them as you can see:
Most cases have space in the back for excess cables to hang out in peace (& out of sight)
Ok, now you've considered a little basic cable management to save you trouble later on, and you're certain of where the front panel cables connect to, it's time to plug them all in. Do this carefully and don't force anything too hard as they should naturally plug in without much effort. The exception being the USB 3.0 connector which is a bigger connector and may need a little extra push to insert correctly, but make sure you've aligned it the right way before adding any force to it so you don't damage anything.
Connect your case's front panel connectors to the correct motherboard headers
Also be aware some of the front panel connections (the power switch, HDD LED and power LED for our particular board and perhaps the same for you) have both a positive and negative connection to link up to the corresponding positive and negative port on the motherboard. These three (or six if counting the + and -) wires will likely need to connect onto the same port on the motherboard (a row of double pins) side by side, and without spacing between them. Incorrectly installing the front panel connections may lead to damaging the board and/or first boot problems, so don't rush this process and get the connections right.
