9 Best Low Power Graphics Cards Without External Power in 2021 [Expert Recommendation]

When talking about Gaming while saving electricity, Low Power Graphics Card is an essential part that you will need to buy. Whether you are about to build your gaming PC from scratch or maybe you are upgrading your PC, these cards that fit into your motherboard will be key to your Gaming Experience.

These cards, also called expansion slots allow you to play games at the maximum level of resolution with a high frame rate at the same time. These components provide a bridge between output images and a display device. They hold a small chip-like structure on them, which is called the Graphics Processing Unit or GPU for short. And this chip is responsible for all of this process.

So if you haven’t figured it out yet, the Graphics Cards are an essential part of Gaming rigs. But the problem that they come with is that they draw too much power. This is something that you cannot really fault them for. After all, they are working really hard.

This is the reason why they get so hot and you need heavy-duty cooling systems with a Gaming PC. But worry not as not all Graphics Cards are power-hungry monsters that require you to spend hundreds of dollars on the power supply alone.

With the low-power Graphics Cards that we have mentioned below, you will not need an insane external or internal power supply. Rather you will be able to run these expansion cards at low power.

This will save you some bucks as well as help if you are looking to upgrade an existing gaming setup. So keep on scrolling and look at the Best 9 Low Power Graphics Card Options Without External Power in 2021.

Low Power Graphics Card – A Buyer’s Guide

When buying anything related to PC or gaming, it is easy to get confused. There is just so much terminology related with each product, in order to buy a product that fits your needs exactly can be hard.

But worry not as we have got you covered! Consequently, we have come up with a buyer’s guide to help guide you through the process of buying a low power graphics card.

Form Factor

A low power graphics card comes in different form factors. This is basically the expansion cards dimensions. The size, shape, etc. This is one of the important things to look out for if you already have a setup and you are thinking of upgrading your card.

This is because if you get a card that does not fit in your casing, it will be of no use. On the other hand, if you are building the PC from scratch, this can be a little flexible. As you can then mix and match different sizes with each other on demand.

Memory Size

Majority of the times, the card that you get and its performance depends upon the size of its memory. You will find this written besides a card mostly. On this list, we have mentioned cards that are either 2GB or 4GB in memory size.

There are cards that have a higher memory size, such as 6GB and 8GB but, for those you also have to get external power.

4GBs would be enough for a gamer that wants to play games at 1080p and at a stable frame rate. On the other hand 2GB cards are mostly for light gaming usage.

Generally, the higher the memory size for a card, the better its performance will be. As the increased memory size is often accompanied by a higher GPU Clock and CUDA Cores.

Output Ports

These ports are the place at which your screen monitor will be connected to your GPU. If you remember the start of this article, we mentioned that these cards play a part in the video part of gaming.

So you need to look out for the ports that the graphics card has so that you will be able to connect the monitor that you have to the card. If not, you will either have to change the card or the monitor.

GPU Clock / CUDA Cores

Both of these are measures of the performance that your expansion card offers. Though when you compare these numbers with cards that are based on different architectures, you do not get substantial information.

In cards, you will often hear the term of OverClocking. This basically means to make the card perform faster than its normal speed. It can be harmful to the card in prolonged periods of time, but it does give quite a significant boost in performance.

Power Consumption

There has been an upwards trend in the market of GPUs over the past couple of years. As these cards have become more powerful, the more power-hungry they have become.

Nowadays you can find PCs that consume power of upwards of 200W. I mean they do deliver for that amount of power but still, for only the expansion card, that is a lot.

When it comes to power, there are two different terms you need to know. One is the power that the card will consume on its own. The other is called the Power Supply Unit or PSU. The PSU will always be a greater number than the power consumption of the card itself.

Frequently Asked Questions

What are low profile Graphic Cards?

The difference between Low-Profile Cards and Standard cards is in their power consumption and the performance that they offer. Because of how low profile cards are smaller in size, they end up being slower and they consume less energy too. On the other hand though, they also are cheaper as well as generate less heat.

What are GPU benchmarks?

GPU benchmarks are a standard of finding how good a graphics card is. There are certain tests online that one can do to find out the power of their cards. These tests check the card vigorously by pushing it to the limit. When conducting these tests, you may find the temperature levels for your device to shoot up too.

Why is external power needed for some Graphics Cards?

Over the years, as these cards have become necessary for gaming, companies have started to open new horizons when it comes to the performance for these components. Because of that, the power requirement needed to run these cards have shot up too. In order to match those demands and to make the card run smoothly, getting an external power supply ends up becoming necessary.
