Building a new PC can be tricky. You don't just get some random parts and assemble them together. How do you make sure that a certain graphics card is compatible with the rest of your system? Getting a new GPU and simply plugging it in might work, but if you don’t make sure that your system is compatible, you could seriously endanger it. Why take an unnecessary risk of the graphics card compatibility checker is so simple?
The good news is that most modern GPUs have been compatible with almost any motherboard from the last decade. Even so, it’s better to be safe than sorry. You will only need graphics card compatibility checker if you’re getting a dedicated GPU. If you’re planning to game using your integrated graphics card (which is possible and sometimes even decent with newer technology), you can be sure it’s already compatible.

Make Sure You Have Enough Physical Room For Your New GPU
This is an aspect that is easily forgotten, but one that can mess with graphics card compatibility checker. Make sure you know the specifications of your case, as you can easily check the dimensions of the graphics card, which are usually readily available on the manufacturer’s website. If you either forget the type of case you have or can’t identify it, you can always manually measure the inside of the case with a tape measure. This isn’t the most convenient method, but it serves its purpose as a last resort. Just make sure the PC is turned off and unplugged when you do this.

While graphics card compatibility checker is essential, it’s equally important to ensure that all the extra cables for the GPU and other nearby components have sufficient room and won’t be bent. Measuring the space in your PC is crucial when determining if your rig will have enough room to breathe. Proper airflow is key to keeping your PC at the optimal temperature. The GPU is probably the most significant heat generator inside the case, so you should be extra careful to ensure that air can flow around it freely and provide proper cooling.
