When building a PC with a GTX 1070 GPU, many people are confused about what Power Supply to pair with this GPU. This article will help you find the right power supply for this GTX 1070 graphics card.
Here’s The PSU Requirements For The GTX 1070 GPU
When choosing a PSU for the GTX 1070 GPU, there are three important things to keep in mind. Firstly, we need to ensure the PSU can deliver sufficient wattage. Secondly, we need to see if the PSU has enough PCIe cables for the GPU. Lastly, we also need to check if it has a good efficiency rating.
These are the primary requirements that the GTX 1070 GPU needs from its Power Supply, and now we’ll go into more depth about these requirements and select some of the best PSU options for this GPU.
What PSU Watts For GTX 1070 GPU?
According to Nvidia, this GTX 1070 GPU requires 150W power under extreme load, and they recommend a 500-watt Power Supply for this GPU.
But you can’t pick the PSU wattage based on Nvidia’s recommendation because it can lead to purchasing a PSU with an incorrect wattage.
That’s why it is important to calculate the power consumption of all the system components and then do the estimation of the wattage.
In order to do the proper estimation, we will pair this GTX 1070 GPU with all the mid-range and budget-end components to determine what PSU wattage we should pick.
We won’t pair the GTX 1070 GPU with high-end components because it can cause bottleneck problems. That’s why pairing this GPU with high-end components is not recommended.
Now, before diving deeper into it, check the table below to understand how much wattage each PC component consumes.
GTX 1070 GPU With Mid-Range Components
If anyone pairs this GTX 1070 GPU with a mid-tier CPU and other mid-range PC components, then the estimated power consumption would be like this.
| Components | Peak Power Consumptions |
| GTX 1070 GPU | 150 watts |
| Mid-Tier Intel CPUs (e.g., Intel Core i5 13600K) | 181 watts |
| Mid- Tier Ryzen CPUs (e.g., Ryzen 7 7700X) | 142 watts |
| 1 SSD | 9 watts |
| 2 Hard Disk | 40 watts |
| Motherboard | 70 watts |
| 2 RAMs (16 GB) | 30 watts |
| 3 Case fans (120mm) | 18 watts |
| 1 CPU fan (120mm) | 6 watts |
| Total= 504 watts with Intel CPUs Total= 465 watts with Ryzen CPUs |
If you pair this GTX 1070 GPU with a mid-tier Intel CPU (e.g., Intel Core i5 13600K) and other mid-range components, then the anticipated power consumption would go up to 504W. By having the overclocking & future upgrade factor in mind, you should pick a 600W power supply for this kind of system.
However, if you pair this GTX 1070 GPU with a mid-tier Ryzen CPU and other mid-range components, then the estimated power consumption would go up to 465W. To keep the overclocking & future upgrade factor in mind, you should pick a 550W PSU for this kind of system.
GTX 1070 GPU With Budget-Range Components
If anyone pairs this GTX 1070 GPU with a budget-tier CPU and other budget-range components, then the estimated power consumption would be like this.
| Components | Peak Power Consumptions |
| GTX 1070 GPU | 150 watts |
| Budget-Level Intel CPUs (e.g., Intel Core i9 11900K) | 125 watts |
| Budget- Level Ryzen CPUs (e.g., Ryzen 5 3600X) | 88 watts |
| 1 SSD | 9 watts |
| 1 Hard Disk | 20 watts |
| Budget end Motherboard | 60 watts |
| 2 RAMs (8 GB) | 14 watts |
| 2 Case fans (120mm) | 12 watts |
| 1 CPU fan (120mm) | 6 watts |
| Total= 396 watts with Intel CPUs Total= 359 watts with Ryzen CPUs |
If you pair this GTX 1070 GPU with a budget-tier Intel CPU and other budget-end components, then the estimated power consumption would go up to 396W. By keeping the overclocking & future upgrade factor in mind, you need to pick a 500W PSU.
However, if you pair this GTX 1070 GPU with a budget-tier Intel CPU and other budget-end components, then the estimated power consumption would go up to 359W. By keeping the overclocking & future upgrade factor in mind, you should pick a PSU between 450W and 500W.
PCIe Cables Required For GTX 1070 GPU
The GTX 1070 GPU is a mid-range graphics card, and you have to provide power to this GPU via extra PCIe cables.
The number of PCIe cables required for GTX 1070 GPU depends on whether you’re using a funder’s edition GPU or GPU from a third-party manufacturer.
Generally, third-party GPUs typically need more power than Founders Edition GPUs, so they require more PCIe cables.
If you buy a Founder’s edition GTX 1070 GPU, then you need one 8-pin PCIe cable from the Power Supply.
However, if you also buy this GPU from a third-party manufacturer, such as if you buy “EVGA GeForce GTX 1070 FTW GAMING GPU,” then you need two 8-pin PCIe cables from the PSU.
That’s why it is important to check the specifications of the GPU to decide how many PCIe cables are required, but you’ll most likely need an 8-pin PCIe cable for this GPU.
PSU Efficiency Required For GTX 1070 GPU
The Power Supply efficiency is an important parameter that we need to check before buying a Power Supply.
A good Power Supply always comes with 80 plus certifications that indicate the energy efficiency of the PSU.
The 80 Plus PSU is categorized into different efficiency levels, including- 80 Plus White, Bronze, Silver, Gold, Platinum, and Titanium. You can read this article about- different PSU efficiency.
Among these different levels, the 80 Plus Bronze, Silver, and Gold offer excellent performance within the budget range.
So, if you’re planning to pair this GTX 1070 GPU with mid-range or budget-end components, then opt for an 80-plus Bronze-rated power supply.
Do not buy a Power Supply that has 80-plus white-rated efficiency or doesnt have any efficiency ratings.
Best PSU To Pair With GTX 1070 GPU
Here, I have mentioned a PSU that most PC builders are pairing with this GTX 1070 GPU.
Recomended PSU For GTX 1080 With Mid-Range & Budget-End Components
This GTX 1070 GPU with mid-range components needs a PSU between 550W and 600W. However, if you pair this GPU with budget-end components, then it needs a PSU between 450W and 500W.
But, if you purchase a 450W PSU, then you won’t get the 80 plus Bronze efficiency rating and additional PCIe cables for the GPU. That’s why most PC builders prefer a 550W Power Supply.
For this kind of system, most PC builders are using the Cooler Master Master Watt series PSU.
This is a modular Power Supply with a 120mm temperature control fan and has an 80 Plus bronze certification.
This PSU is also available at different wattage ranges between (550W to 750W), including the 550W versions. You can check the price of this PSU on Amazon.
FAQ’s
Is 450W—500W PSU Enough For GTX 1070?
A PSU between 450W to 550W is enough for a GTX 1070 graphics card when you pair this GPU with a budget-end CPU (such as Intel Core i9 11900K or Ryzen 5 3600X) and other budget-range components. Otherwise, you will need a more powerful power supply.
Is 600w Enough For GTX 1070?
A 600W power supply is enough for a GTX 1070 graphics card if you use a mid-range CPU (like Intel Core i5 13600K or Ryzen 7 7700X) and other mid-range components. But for a high-end CPU and top-tier components, you will need a more powerful power supply.
