Power Requirements for NVIDIA GTX 960: One or Two 6-Pin Connectors?

The NVIDIA GTX 960 is a popular mid-range graphics card, appreciated for its balance of performance and affordability. When it comes to powering the GTX 960, users often question whether both 6-pin power connectors are mandatory, or if the GPU can boot up and function with just one. This article delves into the specifics, offering insights and guidance to help you make informed decisions.

Can the GTX 960 Boot with One 6-Pin Power Connector?

Technically, the GTX 960 can boot up and function with just one 6-pin power connector attached to it. However, the performance and stability of the GPU heavily depend on the specific model and the power demands of the applications you are running. While it might function in basic operations, underload or graphics-intensive tasks could result in instability or reduced performance. To ensure optimal performance and reliability, it is always best to connect both 6-pin power connectors if possible.

The Importance of Adequate Power Supply

For those who might only have one available 6-pin power connector, it is crucial to consider the power supply unit (PSU) capabilities. A PSU is responsible for delivering the necessary power to your components, and a cheap or underpowered PSU can lead to significant issues. A cheap PSU, like a poorly built car stereo amplifier, is more of a gamble, and the risks significantly outweigh the benefits. While a cheap PSU might not cause immediate harm, over time, it can reduce the lifespan of your other components, increasing the chances of failure during gaming or other high-performance tasks.

What Happens if Only One Connector is Used?

If the power supply can only provide power through one 6-pin connector, the risk of failure increases dramatically. In the best-case scenario, your system may shut down abruptly when gaming due to insufficient power. The worst-case scenarios are far more concerning. There is a high chance (around 70%) that the PSU will fail, potentially frying your GPU, motherboard, or both. In rare but extreme cases, there is a small chance that the PSU could even catch fire, making a good PSU an essential investment.

Alternative Solutions: PCIe Power Splitters

To mitigate these risks, a practical alternative is to use a 6-pin PCIe power splitter cable. A splitter cable, such as the Cable Matters 2-Pack 6 Pin PCIe Splitter Cable, allows you to power your GTX 960 with a single 6-pin connector from your PSU. This cable effectively splits the power from a single connector, ensuring that the GPU receives the necessary power. However, it is vital to ensure that your power supply can provide more than adequate power to your GPU, as the splitter only solves one half of the equation.

Conclusion

While the GTX 960 can typically function with only one 6-pin power connector, it is highly recommended to connect both for optimal performance and reliability. A high-quality and adequately powered PSU is a non-negotiable requirement for maximizing the potential of your GPU. Investing in a reliable power supply can save you from potential headaches and costly repairs down the line. Always ensure that the power requirements of your GPU are met to prevent any issues, and look into solutions like power splitters if you are limited by the number of connectors available.
