What Psu For Gtx 970?

When building a new computer or upgrading an existing one, choosing the right power supply unit (PSU) is crucial to ensure proper functioning of all components. This becomes even more important with high-end graphics cards like GTX 970, which require a certain amount of power to function optimally. Investing in the right PSU can save users the trouble of facing compatibility issues, instability, and even damage to the hardware.

Most GTX 970 graphics cards require a PSU with at least 500W of power output, but this can vary depending on the specific model and additional components in the system. It is important to consider factors such as efficiency, quality, and durability while selecting the appropriate PSU. In this article, we will discuss some of the factors to consider when choosing the right PSU for GTX 970 and recommend some popular options available in the market.

What PSU is required for GTX 970?

A PSU (Power Supply Unit) is an essential component of a computer system that converts AC power from the wall outlet to DC power that can be used by the computer’s components.

When it comes to using a GTX 970 graphics card, the following points should be considered for the PSU requirement:

– The GTX 970 has a recommended power supply requirement of 500 watts. This means that the PSU should be able to provide a continuous power supply of at least 500 watts to the computer system.
– The actual power consumption of the GTX 970 may vary depending on the system configuration and the workload. Under heavy load, the power consumption can reach up to 225 watts. Therefore, it is recommended to have a PSU with a slightly higher wattage rating to ensure that there is enough headroom for the GPU to operate under full load.
– When selecting a PSU for a GTX 970, it is important to consider the efficiency rating. Higher efficiency ratings mean that the PSU will convert more of the AC power into DC power that can be used by the computer, resulting in less energy wasted as heat. A PSU with at least an 80 Plus Bronze rating is recommended.
– The PSU should also have the appropriate power connectors required by the GTX 970. The card usually requires one 6-pin and one 8-pin power connector. Ensure that the PSU has these connectors and they are of sufficient length to reach the card.
– It is also important to consider the overall system configuration while selecting a PSU. If there are other power-hungry components like a high-end CPU or multiple hard drives, a higher wattage PSU may be required.

In summary, a PSU with a wattage rating of at least 500 watts, 80 Plus Bronze efficiency rating, and the required power connectors for the GTX 970 is recommended. Ensure that the PSU has enough headroom to handle the GPU under heavy load and consider the overall system configuration as well.


1. What is the ideal PSU requirement for GTX 970?
The ideal PSU requirement for GTX 970 is 500 watts or higher.

2. Can I use a lower wattage PSU for GTX 970?
While it is possible to use a lower wattage PSU, it is not recommended as it may cause instability and damage to the GPU.

3. Which PSU brands are recommended for GTX 970?
Some recommended PSU brands for GTX 970 are Corsair, EVGA, Seasonic, and Thermaltake.

4. What should be the minimum amperage on the +12V rail for a GTX 970 compatible PSU?
The minimum amperage on the +12V rail should be at least 42 amps for a GTX 970 compatible PSU.

5. Can I use a modular or semi-modular PSU for GTX 970?
Yes, you can use a modular or semi-modular PSU for GTX 970 as long as it meets the minimum wattage and amperage requirements.


In summary, choosing the right PSU for your GTX 970 is a crucial step to ensure optimal performance and stability of your system. It is recommended to go for a power supply unit that has high efficiency rating, enough wattage, and at least one 8-pin PCIe power connector. With the right PSU, you can enjoy high-quality graphics and gaming experiences without worrying about power issues. So, before you make your final decision, consider the factors discussed above and make an informed choice.
