If you need a particular answer to your GPU requirements question, please leave a comment below, and we will respond with a solution as soon as possible.

Do not Overload your PSU

Firstly, it is important not to use a graphics card that has a PSU requirement more significant than the PSU capacity. Using an underpowered PSU can hurt you because the motherboard and other capacitors need to work harder with increased ripple. There is a risk of the PSU, and there is also the chance you will lose your hard disk.

Do all computers have a Graphics Card?

This a great question that was raised by one of our readers. The short answer is yes. Every computer does have a graphics card but not every computer has a dedicated graphics card. Most of the computers you’ll find out there today only have what’s called an integrated graphics card which are usually made by Intel.

These are not suitable for displaying quality visuals on your monitor and you’ll need a dedicated GPU if you want to have a good experience for purposes such as gaming.

This is perhaps your best choice because the recommended power supply requirement for it is only 300 watts. It has 768 CUDA core shader units with a base clock of 1290 Mhz. Memory speed is Gbps. It also supports G-SYNC monitors, Nvidia GPU boosts 3.0, Vulkan API, Ansel, Open GL 4.5, and GameStream.

It is not, however, suitable for virtual reality gaming as the GPU has not been configured for that purpose. Seventy-five watts is what it will consume of your 300-watt power supply so bear that in mind. Furthermore, if you want to create a multiple monitor setup, then you will need to choose the 2GB 1050 version because the TI and 3GB version doesn’t support dual or triple monitor displays.

For games such as Overwatch, Gears of War 4, and Grand Theft Auto V, the GTX 1050 has shown close to 2x the performance upgrade. It is sold by several vendors including Asus, EVGA, MSI, Gigabyte, PNY, and Zotac. The reason why multiple vendors sell the same NVIDIA Graphics Card is that the vendors are paid a royalty and most of the time the vendor includes extra features of its own to enhance or differentiate its product from competing vendors.

AMD has not made our list for any of its Radeon or other model graphics cards because they are generally dependent upon at least 400 watts of PSU. However, there are models such as the RX550 which are dependent upon the motherboard and do not have any external power supply requirements.

You are welcome to decipher whether your motherboard can support an AMD graphics card on your own or use our support system by leaving us a comment. Virtual reality gaming is not possible on a 300-watt power supply as most graphics’ cards will not accommodate that PSU rating.

As a result, if you want to game using VR ready technology, you will likely need to upgrade your entire system. Otherwise, for a more practical setup, adhere to our recommendations and collect the GTX 1050 as your best choice for a 300W PSU supported graphics card.
