We’ve got all the parts and now it’s time to put it all together! If this is your first build, it may be a bit daunting, but watch some tutorials on YouTube to get a feel for how it’s done first and then give it a shot. It’s really not too difficult, sort of like putting together a Lego set– everything snaps into place and only fits one way. With that said, let’s start by installing the CPU, RAM, and heatsink/fan onto the motherboard before we do anything else.
The CPU installation is pretty simple: lift up the lever, match up the little triangles on the corner and drop in the chip. It only fits one way and it should drop right into place. Lower the lever and you’ve just installed the CPU. Easy peasy. Next, let’s put the RAM in place.
RAM is another easy install. If you’re using two sticks of RAM, make sure the sticks are in the correct slots, for my board slots 1 and 3 were the ones to use. Check out your motherboard manual for the correct configuration for your particular board. There’s a little notch in the RAM stick that will line up with the one in the slot. Make sure you open the levers on the side and press the stick into place until it clicks into place. Do the same with any remaining sticks of RAM. You’re done! Now, let’s move onto the heatsink/fan.
Installing the HSF (heatsink/fan) looked like a bit of a challenge, but in the end it was just a little bit more difficult than dropping in the CPU. I watched a few install videos and took the advice to install it outside of the case to make it easier. I’m glad I did. With the Gammmaxx 400, you will need to first install the correct bracket for your CPU socket. After that, it’s time for the thermal paste. Put a pea-sized dab on top of the CPU and install the HSF. The dab of thermal paste will spread out as you press it on and install it. If you’re nervous about installing it like I was at first, watch a few videos to get the hang of things, and when you’re confident, go for it and install it. I thought it seemed to require a little bit more pressure to install than I was expecting but overall the install was pretty easy considering this was my first tower-style cooler I’ve installed (I’ve always just used the stock box coolers in my previous builds).
Next, grab your case and open it up. Take a look and get an idea of where the motherboard will live in the case. Make sure the standoffs are in the proper place for your motherboard screws. My case had them preinstalled for a standard ATX motherboard so all I had to do was press in the I/O shield and slide in the motherboard. Make sure all the ports line up with the I/O shield before you attach any screws and secure the motherboard with the screws that came with your motherboard or case, there should be about nine for a standard ATX motherboard.
Next you can put in the storage drives. These are pretty simple to install. The setup of these depends on your case, the manual that came with the case should give you an idea of how these fit in. Grab the SATA cable and attach it to your motherboard and drive and put it into place. Done. Now to put in the PSU and power it up!
I had quite an adventure with the PSU. But before we get into that, let’s get the PSU installed. There are three types of PSUs that I came across: Modular, Semi-modular, and non-modular. I decided to go for the modular, which means you can detach any of the cables you don’t need for better cable management. The main cables you’ll need to power your PC are the MB, CPU, PCI-E, SATA, and if you have a lot of fans you’ll want to add the ACC cable as well. Find the connections on your motherboard, attach the cables to their respective pieces of hardware and secure the PSU with the screws. Attaching the cables before installation is much easier than installing the PSU first and installing the cables. After the PSU is secured and the cables are all attached, (double check the connections to be sure!) it’s time to power up your PC for the first time! Wait! I forgot– make sure all your case jumpers (Power button, Reset, front USB, etc.) are attached to the motherboard as well! Now, let’s fire it up!
Now, it’s important that you know where the power button is on your case. I didn’t know where the power button was at first, so I kept pressing the reset button without any result. I tried different power cables, re-attached cables and still no power. I even picked up a spare power supply and got the same result. Then, I realized with a facepalm, I was pressing the reset button instead of the power button. I thought the power button was just a Cooler Master logo on the top of my case. Derp, oh well. It fired up fine with the spare I picked up and I was pumped! But, I had to troubleshoot my original PSU and see what was up. I tested it again later on and still nothing. I knew it had to be an issue related to the PSU so I ended up filing an RMA with EVGA. My motherboard just doesn’t seem to like the EVGA PSU, and soon enough I’ll have an answer for this mystery.
That’s it! You built a PC! All that is left is to install an OS: Windows 10 or any of the various flavors of Linux should work fine. Fire it up, run benchmarks, be productive! Or join the fun in Night City and play some Cyberpunk 2077! I’ll see you there!
