So, what is the gaming PC power usage in reality?

By and large, a gaming PC can have different amounts of power usage depending on the hardware it houses. Therefore, looking at your requirements, your PC can demand more or less power. However, as a rule of thumb, a gaming PC generally requires anywhere between 400 to 700 watts. Also, make sure to read our guide on how much it costs to ship a PC


Key Takeaways

  • A PC’s main power consumption stems from the graphics card and processor, so create a build centered around products with better TDP.
  • In most cases, an AMD build consumes lower power than an Intel build.
  • Generally, buying a stronger power supply than required will pave the way for future builds.
  • For mid-range and high-end builds, buying 80+ ranking power supplies is important for greater performance.

Wattage Intensive Components

Before we look at the amount of power different builds require, we must discuss components that require more wattage. So far, the two components that require the most wattage are the CPU and the GPU. Thus, when building a computer that uses less power, you must look at the power requirements for both components.

Graphics Card Power Requirements

Of course, when we look at the power usage of a PC, the graphics card consumes the most. However, certain graphics cards have lower power requirements than others. So, when building a PC, knowing the required Thermal Design Power (TDP) of a graphics card is imminent.

For example, analyzing mid-range graphics cards, we have the NVIDIA GeForce RTX 3060 and the AMD Radeon RX 6600 XT. While there is a small difference in the performance of both GPUs, their power requirements are similar. To clarify, the NVIDIA GeForce RTX 3060 requires at least 170W, with a recommended 350W power supply. On the other hand, the AMD Radeon RX 6600 XT requires at least 160W, with a recommended 350W power supply.

Furthermore, looking at high-end options, we have the NVIDIA GeForce RTX 3090 and the NVIDIA GeForce RTX 4090. Although, only a few consumers are willing to buy the RTX 4090 due to its price and immense power requirements. In conclusion, a graphics card usually requires over 300W power, up to 1000W.

Processor Power Requirements

Moving to the second component that requires the most power, we have processors. While processors generally don’t require as much power as GPUs, their requirements might not be easy to handle. For that reason, we must look at a few processors from different price segments to find their power requirements.

Firstly, analyzing the mid-range market, we have the AMD Ryzen 5 3600 and the Intel Core i5-11600K. Consequently, the AMD Ryzen 5 3600 has an expected TDP of 65W. However, using a 400W power supply is recommended. Subsequently, the Intel Core i5-11600K has a TDP of 125W. Therefore, using a 500W power supply or higher is recommended with the 11600K.

Secondly, moving towards the higher-end market, the AMD Ryzen 9 7900X and the Intel Core i9-13900K dominate the market. Notwithstanding, the AMD Ryzen 9 7900X has a TDP of 170W. On the other hand, the Intel Core i9-13900K has a TDP of 125-253W. So, to properly utilize both processors, consumers need at least a 700W power supply.

Lastly, a processor may require 300W to 800W power to run efficiently. Although, if you plan to overclock your components, you will need even more power.

Low-End Gaming PC Power Requirements

After looking at the power-intensive components, let’s glance at different range gaming PCs and their power requirements. Because not all gamers can afford high-end PCs, it’s important to look at different categories from Intel and AMD to determine which is more power efficient. So, without further ado, let’s dive into the power requirements of low-end gaming PCs.

Low-End Intel Gaming PC

While looking at the following image, we see a fairly low-end build, considering the currently available hardware. Because we’re looking at an Intel-oriented build, we are using an NVIDIA graphics card.

Be that as it may, for the processor, we are going with the fairly durable Intel Core i3-6300. Also, the processor has a TDP ranking of 51W. So, you don’t have to worry about extreme power consumption either. Furthermore, the Intel Core i3-6300 showcases the outstanding performance, even though it has gotten old.

Of course, to complement the Intel Core i3-6300, we have the Asus H110M motherboard. But because we’re looking at a low-end build, we couldn’t choose a better motherboard suited for the processor.

Looking at the graphics card, we’re going with the NVIDIA GTX 1050 Ti. By all means, the NVIDIA GTX 1050 Ti is an old GPU. However, it is sufficient to run most triple-A title games at low settings to this day. So, if budget is a problem, the NVIDIA GTX 1050 Ti is a great GPU. In any case, the NVIDIA GTX 1050 Ti has a TDP of 75W.

With all the other components within the PC, we have an estimated wattage of ~221W. So, buying a 400W or greater power supply should be the ideal choice. In the long run, owning a higher-wattage PSU will be more beneficial. Because power supplies usually have a longer lifetime, they outlive multiple builds.

In conclusion, if going with an Intel build with a lower budget, buying an Intel Core i3-6300 with an NVIDIA GTX 1050 Ti is a great option. Additionally, you can increase the amount of RAM if needed. At length, the entire build will require anywhere between 200-250W power.

Low-End AMD Gaming PC

After looking at the Intel build, we must also look at an AMD equivalent. While we see a better processor, the GPU is lacking in performance. However, even with the AMD Radeon RX 550, consumers can get along with most of their gaming requirements. 

Firstly, glancing towards the AMD Ryzen 5 1600, it’s a great processor with amazing performance capabilities. Also, the AMD Ryzen 5 1600 barely requires a 65W TDP. Therefore, the performance stands even if its TDP requirements are slightly higher than the Intel Core i3 6300’s. Of course, according to today’s standards, the Ryzen 5 1600 has gotten old but provides adequate performance at lower prices.

Secondly, moving toward the graphics card, we’re going with the AMD Radeon RX 550. Although a redundant graphics card today, AMD fans will enjoy its performance in their low-budget builds. Furthermore, the AMD Radeon RX 550 has a TDP requirement of barely 65W. But, it’s important to note that the AMD Radeon RX 550 holds no candles against the NVIDIA GTX 1050 Ti. So, if performance is an issue, you might want to go with the latter.

In any case, the lower-end gaming PC power usage for an all-AMD build is around 227W. For that reason, going with a 400-450W power supply should be sufficient. Nonetheless, buying a higher-wattage PSU will help for future builds, as power supplies tend to outlive several builds.

Lastly, an AMD Ryzen 5 1600 and an AMD Radeon RX 550 build, while lacking in performance, are amazing. On the other hand, you can mix and match AMD and NVIDIA products for better results. So, an AMD processor and NVIDIA GPU could potentially be more useful.

Mid-Range Gaming PC Power Requirements

Moving towards the more expensive ranges, let’s talk about mid-range gaming PCs and how much power they require. On average, a mid-range gaming PC might require anywhere from 500W to 700W of power. However, let’s take it into greater detail with Intel and AMD builds!
