The NVIDIA GeForce GTX 1070 is a powerful graphics card that was released in 2016. It was a popular choice among gamers and graphics enthusiasts due to its impressive performance and relatively affordable price. However, one of the most common questions that people ask when building a gaming PC with a GTX 1070 is whether a 500W power supply is enough to power the system.
Understanding the Power Requirements of the GTX 1070
The GTX 1070 has a TDP (Thermal Design Power) of 150W, which means that it requires a minimum of 150W of power to function properly. However, this is not the only factor to consider when determining the power requirements of a system with a GTX 1070. Other components such as the CPU, motherboard, RAM, and storage devices also require power, and these requirements can add up quickly.
Calculating the Total Power Requirements of a System
To determine whether a 500W power supply is enough for a system with a GTX 1070, we need to calculate the total power requirements of the system. Here’s a breakdown of the typical power requirements of different components:
- CPU: 65W – 125W (depending on the model and clock speed)
- Motherboard: 20W – 50W (depending on the model and features)
- RAM: 10W – 20W (depending on the type and amount)
- Storage devices: 10W – 20W (depending on the type and number)
- GTX 1070: 150W
As you can see, the total power requirements of a system with a GTX 1070 can range from 255W to 415W, depending on the specific components used. However, this is not the only factor to consider.
Power Supply Efficiency and Overhead
Power supplies are not 100% efficient, and they require some overhead to function properly. The efficiency of a power supply is typically measured by its 80 PLUS rating, which ranges from Bronze to Titanium. A higher 80 PLUS rating indicates a more efficient power supply.
In addition to efficiency, power supplies also require some overhead to handle peak power demands and to provide a margin of safety. This overhead is typically around 10% – 20% of the total power requirements.
Is 500W Enough for a GTX 1070?
Based on our calculations, a 500W power supply may be sufficient for a system with a GTX 1070, but it depends on the specific components used and the efficiency of the power supply.
If you’re building a system with a low-power CPU, a basic motherboard, and a single storage device, a 500W power supply may be enough. However, if you’re building a system with a high-power CPU, a feature-rich motherboard, and multiple storage devices, you may need a more powerful power supply.
Here’s a rough estimate of the power requirements of different systems with a GTX 1070:
- Basic system: 300W – 400W
- Mid-range system: 400W – 550W
- High-end system: 550W – 700W
As you can see, a 500W power supply may be sufficient for a basic or mid-range system, but it may not be enough for a high-end system.
What Happens if You Use a 500W Power Supply with a GTX 1070?
If you use a 500W power supply with a GTX 1070, you may experience some issues, such as:
- System instability: If the power supply is not able to provide enough power to the system, you may experience system crashes, freezes, or shutdowns.
- Reduced performance: If the power supply is not able to provide enough power to the GTX 1070, you may experience reduced performance, such as lower frame rates or reduced graphics quality.
- Overheating: If the power supply is not able to provide enough power to the system, you may experience overheating, which can reduce the lifespan of your components.
How to Choose the Right Power Supply for Your GTX 1070
To choose the right power supply for your GTX 1070, you need to consider the following factors:
- Total power requirements: Calculate the total power requirements of your system, including the GTX 1070, CPU, motherboard, RAM, and storage devices.
- Efficiency: Look for a power supply with a high 80 PLUS rating, such as Gold or Platinum.
- Overhead: Consider a power supply with some overhead, such as 10% – 20% of the total power requirements.

What is the recommended power supply for a GTX 1070 graphics card?
The recommended power supply for a GTX 1070 graphics card is at least 500W. However, this can vary depending on the specific system configuration and other components. It’s essential to consider the total power draw of the system, including the CPU, motherboard, RAM, and other peripherals, to ensure the power supply can handle the load.
In general, a 500W power supply should be sufficient for a GTX 1070 graphics card, but it’s crucial to check the specific power requirements of the card and other components to avoid any potential issues. It’s also worth noting that a higher-wattage power supply can provide a buffer against power spikes and ensure stable operation.
Can I use a 500W power supply with a GTX 1070 and an Intel Core i5 processor?
Yes, a 500W power supply can be used with a GTX 1070 and an Intel Core i5 processor, but it depends on the specific system configuration and other components. The Intel Core i5 processor typically has a TDP of around 65W, which is relatively low. However, the GTX 1070 graphics card has a TDP of around 150W, which is significantly higher.
Assuming the system has a moderate number of peripherals and a standard motherboard, a 500W power supply should be sufficient. However, if the system has multiple hard drives, a high-end sound card, or other power-hungry components, a higher-wattage power supply may be necessary to ensure stable operation.
What are the consequences of using a power supply that is too small for a GTX 1070?
Using a power supply that is too small for a GTX 1070 can lead to a range of issues, including system instability, shutdowns, and even damage to the components. When the power supply is unable to provide enough power to the system, it can cause the voltage to drop, leading to system crashes and data loss.
In extreme cases, using a power supply that is too small can cause the components to overheat, leading to premature failure. It’s essential to ensure the power supply can handle the total power draw of the system to avoid any potential issues and ensure stable operation.
How do I calculate the total power draw of my system?
To calculate the total power draw of your system, you need to add up the power requirements of each component, including the CPU, motherboard, RAM, graphics card, and peripherals. You can find the power requirements of each component in the manufacturer’s documentation or on the component’s packaging.
Once you have the power requirements of each component, add them up to get the total power draw of the system. It’s also a good idea to add a 10-20% buffer to account for any power spikes or unexpected power draws.
Can I use a 500W power supply with a GTX 1070 and an AMD Ryzen 7 processor?
A 500W power supply may not be sufficient for a GTX 1070 and an AMD Ryzen 7 processor, depending on the specific system configuration and other components. The AMD Ryzen 7 processor typically has a TDP of around 170W, which is significantly higher than the Intel Core i5 processor.
Assuming the system has a moderate number of peripherals and a standard motherboard, a 650W or higher power supply may be necessary to ensure stable operation. However, if the system has a high-end sound card, multiple hard drives, or other power-hungry components, an even higher-wattage power supply may be necessary.
What is the difference between a 500W 80+ Bronze power supply and a 500W 80+ Gold power supply?
The main difference between a 500W 80+ Bronze power supply and a 500W 80+ Gold power supply is the efficiency rating. The 80+ Bronze certification requires a minimum efficiency of 82% at 20%, 50%, and 100% loads, while the 80+ Gold certification requires a minimum efficiency of 90% at 20%, 50%, and 100% loads.
In general, a higher-efficiency power supply will waste less energy as heat and provide a cleaner power output to the system. However, the difference between a Bronze and Gold certified power supply may not be noticeable in most systems, and the choice ultimately depends on the specific needs and budget of the user.
Can I use a 500W power supply with a GTX 1070 and multiple hard drives?
A 500W power supply may not be sufficient for a GTX 1070 and multiple hard drives, depending on the specific system configuration and other components. Multiple hard drives can add a significant amount of power draw to the system, especially if they are high-capacity or high-speed drives.
Assuming the system has a moderate number of peripherals and a standard motherboard, a 650W or higher power supply may be necessary to ensure stable operation. However, if the system has a high-end sound card, a high-end CPU, or other power-hungry components, an even higher-wattage power supply may be necessary.
