Everything you need to know about GPU and motherboard compatibility
Updated: January 25, 2023 2:55 PM

It is often difficult to make sure that the card will fit on the current motherboard. They are sometimes referred to as “graphics cards” by resellers. Others call them video cards or GPUs. Before buying a card, make sure it is compatible with your computer’s motherboard.
There are specific slots that can be used to connect additional components to motherboards. Most computers have PCI Express 3.0 slots. This means that a video card fits in each slot. The card must be compatible with PCI Express 2.0 or later. AGP slots are used for graphics cards in older computers. These slots can be of different sizes and shapes and will not work with modern cards. In most cases you will need a PCI-E x16 slot. This should be the longest slot on your motherboard.
Most graphics cards require power connections. This requires a 6-pin connector or an 8-pin connector. High performance cards require two connectors. If you are not sure what type of connector your computer’s motherboard uses for graphics cards, refer to the technical specifications. This is important to know before building or upgrading your PC.
Which GPUs are compatible with your motherboard?
Almost all graphics cards from any manufacturer will work with any motherboard. There’s no reason to modify a graphics card to fit a slot on a lower lane, other than obvious room or experience issues.
As the months go by, it becomes more common to mess up or cut off extra PCIe lanes or PCB traces to fit a cramped motherboard. Modern PCIe remains the only physical bus standard in use. The TLDR is if it fits, it works. There are no more logic errors like IRQ.
You can add a graphics card to a motherboard with PCI-E (PCI-EXPRESS). You can buy a GTX 1050 Ti or 1050 graphics card if your SMPS (power supply) has no power connectors. These cards do not require an external power supply, the same goes for the GTX 1650, alongside other GPUs such as the low-profile RX 6400.
