The NVIDIA GeForce GTX 970, a popular graphics card based on the Maxwell architecture, has a maximum total power draw of 148 watts when in use. This figure represents the peak power consumption the card can reach under full load.
Understanding GTX 970 Power Consumption
The GTX 970 is recognized for its energy efficiency, a hallmark of NVIDIA's Maxwell architecture. While the maximum specified power draw can reach 148 watts, the typical Thermal Design Power (TDP) for the GTX 970 is often cited around 145 watts. Specific models from AIB (Add-in-Board) partners, such as MSI's factory-overclocked versions, might exhibit slightly higher peak draws, aligning with the 148-watt figure. This power efficiency allows the GTX 970 to deliver strong performance without demanding excessive power from the system.
Key Power Specifications
Understanding the power requirements is crucial for system builders and upgraders to ensure compatibility and stable operation.
| Characteristic | Value |
|---|---|
| Maximum Power Draw | 148 Watts |
| Typical TDP | ~145 Watts |
| Recommended PSU | 500 Watts |
| Power Connectors | 2 x 6-pin PCIe |
Practical Implications for Users
When integrating a GTX 970 into a PC build or upgrading an existing system, several power-related factors should be considered:
-
Power Supply Unit (PSU) Requirements:
- A minimum power supply unit (PSU) of 500 watts is generally recommended to provide sufficient power for the GTX 970 and the rest of your system components, including the CPU, motherboard, and storage drives.
- Opting for a PSU with an 80 PLUS certification (Bronze, Gold, Platinum, Titanium) ensures better efficiency and reliability.
- Consider future upgrades when choosing a PSU, as a slightly higher wattage unit can offer more headroom.
- For more detailed PSU recommendations based on your full system configuration, online PSU calculators can provide tailored estimates.
-
Power Connectors:
- The GTX 970 typically requires two 6-pin PCIe power connectors directly from the power supply. Ensure your PSU has these connectors available. Adapters can be used in some cases, but direct connections are always preferred for stability and safety.
-
Cooling Considerations:
- Due to its efficient Maxwell architecture, the GTX 970 generates less heat compared to some higher-power or older-generation graphics cards. This translates to lower cooling requirements and potentially quieter operation. However, adequate case airflow is still important for optimal performance and longevity.
The GTX 970's relatively low power draw makes it a versatile choice for a wide range of gaming PCs, balancing performance with energy efficiency. For comprehensive specifications on the GTX 970, resources like the TechPowerUp GPU Database provide detailed insights.
