If your computer’s power supply unit (PSU) can only handle 300 watts, you may want to consider upgrading your graphics card rather than your PSU. Since the price of PSUs has dropped over the years, we advise you to buy one if you can afford to do so. A power supply unit (PSU) will cost you around $80 on average.

We have compiled our best efforts to recommend some standard options for purchase, but the best graphics card for a 300-watt power supply may depend on the specific type of computer you have. Please let us know in the comments below what information you need regarding the GPU requirements, and we will do our best to get back to you as soon as possible with a response.

Do not Overload your PSU

At first, you shouldn’t put in a graphics card whose power supply unit (PSU) needs are higher than your PSU can handle. The motherboard and other capacitors will have to work harder than necessary to deal with the increased ripple caused by using a PSU that is too weak. The power supply unit (PSU) could fail, and data loss is always a possibility.

Do all computers have a Graphics Card?

One of our readers asked a very valid question. The quick response is “yes.” While a graphics card is present in every computer, only some of these machines have dedicated graphics processors. Integrated graphics cards, typically manufactured by Intel, are typically the only type of graphics card found in computers today.

You’ll need a dedicated GPU to get decent visuals on your screen, so avoid these if you care about things like gaming.

Best Graphics Card for 300W PSU

Listed below are the top three graphics cards that can be used with a 300 watt power supply. We’ve done our best to highlight only the most applicable GPUs for your requirements and budget (300 watts is a very practical and modest power supply), as was mentioned earlier.

GPU: GeForce GT 630

*

These NVIDIA graphics cards are from a previous generation and need a minimum of 300 watts to run. You can expect to pay around $60. Each of the three GT 630 variants—the D3, G5, and Kepler—requires at least 300 watts of power to run properly. It works fine on both Windows 7 and Windows 8. In addition, it is compatible with a wide range of monitor configurations and the Direct X 12 API and Open GL 4.2. If you have a pressing need to make use of the supported technologies without spending a fortune on a new GPU, this is the one for you. Verify the current offering on Amazon.

Intuitive Graphics Processing Unit: GeForce GTX 1050

The minimal 300-watt power requirement suggests this may be the best option. An initial base clock of 1290 MHz powers 768 CUDA core shader units. The rate of data transfer in memory is measured in Gbps. Moreover, it works with displays that use the G-SYNC technology, as well as the Nvidia GPU Boost 3.0 API, the Vulkan API, the Ansel filter, Open GL 4.5, and GameStream.

However, the graphics processing unit (GPU) has not been optimized for virtual reality games, so you shouldn’t use it for that. Take into account that it will use 75 watts of your 300 watt power supply. Additionally, the TI and 3GB versions of the 1050 don’t support dual or triple monitor displays, so if you want to set up multiple monitors, you’ll need to go with the 2GB version.

The GTX 1050 has demonstrated a performance boost that is nearly twice as large for games like Overwatch, Gears of War 4, and Grand Theft Auto V. Distributors of this product include Asus, EVGA, MSI, Gigabyte, PNY, and Zotac, among others. Multiple vendors sell the same NVIDIA Graphics Card because each vendor receives a royalty and, in most cases, adds unique features to the card to attract customers and set itself apart from competitors. Look at this!

Visual Processing Unit GeForce GTX 750

A moderately priced graphics option is the Geforce GTX 750. It supports PCI Express 3.0, has a memory clock of 5 GHz, and requires no less than 300 watts of power to operate. It has a length of 5.7 inches and a height of 4.376 inches. A pair of slots for width. It’s equipped to handle a wide range of technologies, including 4K, Nvidia G-Sync, GPU Boost 2.0, DSR, Direct X 12, Ansel, PhysX, and 3D vision. This graphics card also allows for a triple-monitor setup. Read up on the most recent from EVGA here.

Conclusion

Our list does not include any Radeon or other model graphics cards from AMD, as they typically require a power supply unit of at least 400 watts to function properly. Still, there are models like the RX550 that get their power directly from the motherboard and don’t need an AC adapter.

Your motherboard’s compatibility with an AMD graphics card can be determined by leaving a comment or by contacting our support team. Most graphics cards cannot run on a PSU of 300 watts, making it impossible to play virtual reality games on such a system.

Therefore, if you want to play games using VR-ready technology, you will likely need to upgrade your entire system. Otherwise, if you want a more realistic setup, follow our advice and get the GTX 1050, which is the best graphics card you can get with a 300W PSU.
