Checking Compatibility VGA Card and PC System

If you want more CPU performance in order to play the latest games in high resolution and maximum quality, of course what is needed then is a VGA quality. Here we will discuss how to find out if a VGA is match or not match with the PC you have.

Most PCs depend on a graphic card that is integrated directly with the chip on the motherboard or on the CPU body. Meanwhile, there are also PCs that have a separate VGA slot, where users can install their VGA device in the slot.

Usually, a separate VGA slot can be seen easily. You can check it by looking at the location of the port used to connect the graphics card to the monitor. When the port in question is in another slot group like Ethernet and USB, this is usually a sign that your PC chooses graphics that are integrated with the motherboard or CPU. However, if the graphics port is separate, and there is more than one port such as DVI outputs, HDMI or DisplayPort, then it is clear that the PC has a slot for a separate VGA.

PCs with VGA integrated directly with the motherboard, as well as PCs with separate VGA slots, both have expansion slots called PCI Express. This expansion slot is usually in the form of a removable backplate where a VGA card can be placed on it. Then how to find out if the new VGA that we want to buy is compatible with the PC system that is now owned?

Compatibility issues: checks for PCI Express slots

Most PCs have several expansion slots on the motherboard. Usually, they are called PCI Express, but for a VGA card, all it takes is a PCI Express x16 slot. There are three slot versions available on most motherboards today, but they all have an upside-down compatibility. For example, a VGA PCI Express 3.0 will work well on a motherboard with a PCI Express x16 2.0 slot.

Motherboards of that type usually have two PCI Express x16 slots. The most common thing to do is to install a graphics card in one of those slots, but you may want to install a dual VGA to take advantage of AMD Crossfire or nVidia SLI setup. If so, then what needs to be checked is the support of the motherboard to build such a VGA system.

Problem compatibility: length and width of VGA

VGAs that are more qualified for their caliber usually have larger fans and physical dimensions. This then makes the dimensions thicker than the previous VGA. The length and width of the new VGA should be adjusted to the dimensions of the casing. Simply put: you have to make sure that the new VGA is loaded in the PC case. So, find out exactly how many new VGA dimensions you want to install in your PC system, so you do not get it wrong.

Compatibility issues: power demand

Although you may have a PCI Express x16 slot and space in a large casing, you will need extra power for most VGAs. Check the power supply to see if the device has a PCI-E power connector. Connectors like this are usually black, with PCI-E and six pins in 3 × 2.

If the power supply unit does not have such a connector, buy an adapter that will connect the PCI-E connector with a standard SATA or four-pin connector. Be careful with VGA cards that require two PCI Express power connectors, where each connector must be connected to a different 12v rail inside the power supply unit.

Basically, a heavyweight VGA requires at least 600W or more of pure power, to ensure that it works well.
