Summary

• Incorrectly aligning your M.2 SSD or RAM modules before securing them in place can damage the contacts.
• It's uncommon, but bending too many radiator fins on your AIO and breaking your motherboard's PCB can still happen if you're not careful.
• Bending or breaking pins on your CPU or the socket can result in a broken processor, costing you dearly.
• Pulling your graphics card out of the PCIe slot without releasing the latch can damage the contacts on the GPU as well as the motherboard.

If you're about to build a gaming PC, you probably already know the basics — how to budget for a gaming PC, how to match your CPU and GPU, and the common mistakes you should not make while building the PC. However, there are many more precautions one should keep in mind, especially when building a PC for the first time.

PC components are pricey, and not handling them well can sometimes lead to disastrous situations where replacing the component is the only way forward. This can lead to hundreds of dollars lost because of user error, needless panic and regret, and a ruined PC building experience. So, here are the costliest PC building mistakes you can make, according to me.

6 Improperly installing your M.2 SSD

It is rare but possible to damage your SSD

Let's start with what seems to be one of the simplest parts of building a PC. Installing an M.2 SSD (SATA or NVMe) appears straightforward on the surface — align the SSD contacts with the M.2 slot, push it into the slot, and use the provided screw or clip to secure it in place. However, if you're doing this for the first time, it is possible to do it wrong, which can easily damage or even break your SSD permanently.

Not inserting the drive all the way or applying too much pressure when securing it to the slot can end up damaging the contacts or breaking the PCB.

The thing is, you need to push the drive inside the M.2 slot at an angle (around 30 degrees), gently push it into the slot without too much pressure, and then screw the other end to the motherboard without overtightening the screw. Not inserting the drive all the way or applying too much pressure when securing it to the slot can end up damaging the contacts or breaking the PCB.

Considering the cost of some of the newer high-end drives, a damaged 1TB or 2TB NVMe SSD can result in a loss worth anywhere from $70 to around $250.

5 Forcing the RAM into the slot

Take a step back if you encounter too much resistance

Again, installing RAM modules on your motherboard should be one of the simplest tasks when putting your PC together. As long as you've bought the right type of RAM — DDR3, DDR4, or DDR5 — it's difficult to insert them in the wrong position, since the notch on the RAM sticks won't align with an incompatible slot.

With enough pressure in the wrong orientation, you can damage the contacts on the module as well as the motherboard slot.

Still, an inexperienced PC builder might incorrectly align the RAM module with the slot (in the reverse position, so to speak), and try to force it into the slot, naturally facing difficulty while doing so. With enough pressure in the wrong orientation, you can damage the contacts on the module as well as the motherboard slot, breaking one or both of your precious components.

A 32GB kit of DDR5 RAM can cost anywhere from $75 to over $200, depending on the frequency and model, whereas a DDR5 motherboard will cost you around $80 on the low end to over $400 at the high end. Hence, make sure you're aligning the notch on your RAM correctly with that on the slot before pushing down on the module.

4 Denting the AIO radiator

Bending the radiator fins is easier than you'd think

Okay, this one might matter to you a lot or not at all, depending on your latest OCD report from the doctor. If you're installing an AIO liquid cooler for your power-hungry CPU, you might notice that a handful of fins (those zig-zag lines) on the radiator are not perfectly straight. While this is common on almost any AIO you buy, if the number of bent fins is too high, it can negatively affect your system's cooling.

In the worst situation, you might end up with too many bent fins and, consequently, a severely damaged radiator.

While screwing the radiator into the motherboard mount, it's possible to damage some of the fins if you overtighten the screws. This can happen either due to imperfect construction on the manufacturer's side, or due to incorrect screw utilization (as there are a lot of screws in your motherboard box). In the worst situation, you might end up with too many bent fins and, consequently, a severely damaged radiator.

Claiming a warranty on such an item would be tough as the manufacturer will conclude that it was user error that caused the damage (which it probably did). So, you could either stick with a damaged radiator and some reduction in cooling performance, or shell out more for a brand-new liquid cooler, costing you around $100 to $200.

3 Mounting your motherboard too tight

Securing it to the standoffs like your life depends on it

When you're done installing your SSD, RAM, and CPU cooler on the motherboard, it's time to install the motherboard in the case. The standoffs inside your case are there to properly secure the motherboard as well as prevent an accidental short circuit. So, aligning the motherboard correctly with the standoffs is important, but what might be more important is not overtightening the screws to the standoffs.

If you're too enthusiastic during the process, you might apply too many rotations to the screws and end up chipping the outer layer of the PCB, or worse, driving a hole through it. It doesn't happen often, plus motherboard manufacturers don't usually put important circuitry near the standoff areas on the motherboard, but if your day isn't going well, you could end up damaging your motherboard, which is a pricey part to replace.

2 Bending or breaking the CPU or socket pins

I'm sure you're imagining the horror right now

One of the worst, and costliest, mistakes you can make when building a PC is breaking your CPU or the motherboard's CPU socket. Depending on where the pins are located — your CPU or the motherboard socket — handling the components carelessly can result in several bent, or worse, broken pins, which might not be repairable.

CPU or socket pins can get bent at the slightest pressure, so this is not as uncommon as you might think.

Installing a CPU on the motherboard need not be stressful if you follow the instructions to a T, but sometimes, you might be overwhelmed as a new builder, having a tough day, or too tired to think straight. CPU or socket pins can get bent at the slightest pressure, so this is not as uncommon as you might think. Sometimes, aligning the CPU with the socket incorrectly and then trying to secure it will be enough to damage it.

About the cost of the mistake, you're looking at a whole new CPU, so anywhere from $100 to over $500 is possible. And if you damage the CPU socket instead, you'll have to replace it entirely.

1 Forcing the GPU out without releasing the latch

As scary as it gets

Your graphics card is probably the priciest component in your entire gaming PC, so damaging it can easily be the worst mistake you can make. When installing the graphics card on the motherboard, things are relatively simple — release the latch on the PCIe latch, push the card into the slot, and wait for the latch to fall into place.

A new PC builder might forget that the PCIe latch needs to be released manually before pulling the graphics card out.

However, things can get tricky if you need to remove the graphics card during the build process (or later). A new PC builder might forget that the PCIe latch needs to be released manually before pulling the graphics card out. Facing some resistance, one might apply undue force to take the card out, which in the worst cases, can damage the GPU's PCIe connector, the motherboard's PCIe slot, or both.

Besides the horror of the situation, the monetary cost of this blunder can be huge — you might need to replace the motherboard, or worse, spend anywhere from $250 to $1500 on a new graphics card.

Don't be in a rush, take your time with your PC build

Sometimes, we're either too confident or too inexperienced when building a PC, which can lead to undesirable situations like the ones described above. Damaging any component or peripheral of your build is bad, but breaking some of the priciest components can be too much to swallow. Hence, never rush into the process and ensure you're fully prepared, both physically and mentally, before starting a PC build.
