That’s why it’s vital to ensure you have the right PSU wattage for your system, especially when it comes to running multiple graphics cards.
In the following sections, we’ll explore the power requirements of the GTX 960, how to calculate the total power consumption of your system, and the recommended PSU wattage for running two GTX 960 graphics cards. We’ll also discuss important factors to consider when choosing a PSU to ensure compatibility and efficiency. So, let’s dive in and unravel the mystery of how much PSU you actually need for running two GTX 960s in your gaming rig.
Understanding Power Supply Units (PSUs)
Before we delve into the specific power requirements for running two GTX 960 graphics cards, it’s important to have a basic understanding of what a power supply unit (PSU) is and how it functions in a computer system.
The PSU is a crucial component of any computer build as it is responsible for converting the alternating current (AC) power from your wall outlet into direct current (DC) power that your computer components can use. It provides power to all the components in your system, including the motherboard, CPU, graphics card, storage drives, and peripherals.
Power supplies come in various wattages and form factors to suit different computer setups and power demands. The wattage of a PSU refers to the maximum amount of power it can deliver to your components. It’s important to choose a PSU with enough wattage to support the power requirements of all your components, including the graphics cards.
In addition to wattage, PSUs are also rated for efficiency. The efficiency rating determines how effectively the PSU converts AC power to DC power. The higher the efficiency, the less power is wasted as heat, resulting in lower energy costs and a cooler-running system.
PSUs are available in different modularities, including non-modular, semi-modular, and fully modular. A non-modular PSU has all the cables permanently attached, while a semi-modular PSU has some detachable cables. Fully modular PSUs allow you to connect only the cables you need, reducing cable clutter and improving airflow in your system.
It’s important to choose a PSU from a reliable manufacturer with a solid reputation, as a low-quality PSU can not only affect the stability and performance of your system but also pose a risk to the safety of your components. Look for PSUs from well-known brands that offer good warranties and have positive reviews from users and experts.
Now that we understand the basic concepts of PSUs, let’s move on to exploring the specific power requirements of GTX 960 graphics cards and how to calculate the total power consumption of your system.
Power Requirements of GTX 960
The power requirements of a GTX 960 graphics card play a crucial role in determining the wattage needed for your PSU. The GTX 960 is a mid-range graphics card that offers a good balance between performance and power consumption.
Typically, a single GTX 960 graphics card requires a minimum of a 400W PSU. However, when running two GTX 960s in SLI (Scalable Link Interface) mode, the power requirements increase significantly. In SLI mode, both graphics cards work together to render graphics, which results in better performance in games and applications that support SLI.
When operating in SLI, two GTX 960s can consume up to 250W each, depending on the model and manufacturer. This means that for running two GTX 960s in SLI, you would need a PSU with a minimum wattage of 500W. However, it’s always recommended to have some headroom to account for other components, overclocking, and future upgrades.
It’s important to note that the power requirements may vary slightly between different models and manufacturers of the GTX 960. Some models may require slightly more power due to higher clock speeds or custom cooling solutions. Therefore, it’s crucial to check the specifications provided by the manufacturer to ensure you have the correct information for your specific graphics card.
In addition to the power requirements of the GTX 960 graphics cards, you also need to consider the power consumption of other components in your system. These include the CPU, motherboard, RAM, storage drives, and any other peripherals attached to your computer. Each component has its own power requirements, which need to be factored into the total power consumption of your system.
In the next section, we’ll explore how to calculate the total power consumption and determine the recommended wattage for your PSU when running two GTX 960 graphics cards.
Calculating Total Power Consumption
When it comes to determining the total power consumption of your system, including the power requirements for running two GTX 960 graphics cards, it’s important to consider the power draw of all the components in your setup. This will ensure that your PSU can handle the load and provide stable power delivery to your system.
To calculate the total power consumption, you can follow these steps:
- Check the power requirements of your components: Start by looking up the power requirements for each component in your system, including the GTX 960 graphics cards, CPU, motherboard, RAM, storage drives, and any other peripherals. You can usually find this information in the product specifications or user manuals provided by the manufacturers.
- Add up the power requirements: Once you have the power requirements for each component, add them up to get the total power consumption. Keep in mind that some components may have different power requirements depending on usage, such as the CPU during peak processing or the graphics card under heavy load.
- Factor in additional wattage: It’s always a good idea to have some headroom in your PSU wattage to account for future upgrades, overclocking, or additional peripherals. Adding an extra 10-20% to your total power consumption is recommended to ensure your PSU isn’t operating at its maximum capacity.
- Consider efficiency rating: Remember to factor in the efficiency rating of your PSU when calculating power consumption. The efficiency rating determines how effectively the PSU converts AC power to DC power. For example, a PSU with an efficiency rating of 80% will draw more power from the wall outlet compared to its output power to the components. Take this into account when determining the wattage needed for your PSU.
By following these steps and considering all the power requirements, you can calculate an estimate of the total power consumption of your system. This will help you determine the recommended wattage for your PSU when running two GTX 960 graphics cards in SLI.
In the next section, we’ll discuss the recommended power supply unit (PSU) wattage for running two GTX 960 graphics cards based on the calculations we’ve discussed.
Recommended Power Supply Unit (PSU) Wattage
Based on the power requirements and calculations we’ve discussed, the recommended wattage for a power supply unit (PSU) when running two GTX 960 graphics cards in SLI mode is at least 600W. This wattage takes into account the power draw of the graphics cards, as well as the power requirements of other components in your system.
While a 500W PSU can technically handle the power requirements of two GTX 960 graphics cards, it’s always recommended to have some headroom for efficiency, stability, and future upgrades. Opting for a 600W PSU provides that extra cushion of power and ensures that your system operates smoothly under heavy loads, without straining the PSU.
Additionally, if you plan on overclocking your components, it’s recommended to choose a PSU with even higher wattage to accommodate the increased power draw. Overclocking can significantly increase the power requirements of your components, so having a PSU with extra capacity is crucial for stable operation.
When selecting a PSU, it’s important to consider other factors as well. Look for a PSU from a reliable manufacturer with a solid reputation for producing high-quality and efficient power supplies. Consider the PSU’s efficiency rating, modular or non-modular design, availability of necessary connectors, and any additional features that may be important to your specific build.
Keep in mind that these recommendations are based on average power requirements and individual system configurations may vary. It’s always a good idea to refer to the specifications provided by the manufacturers of your components to ensure accuracy. If you are uncertain about the wattage needed for your specific system, consulting with an experienced computer technician can provide valuable guidance.
In the final section, we’ll discuss other important factors to consider when choosing a PSU for running two GTX 960 graphics cards, ensuring compatibility and optimal performance.
