Considerations for the best PSU for RTX 4070 Super
When selecting the best PSU for the RTX 4070 Super, it’s essential to consider more than just the wattage. While a 550W PSU is suggested for the RTX 4070 Super by Nvidia, opting for a 700W or higher PSU provides a safer margin, especially when paired with high-performance CPUs and other components. It’s crucial to account for the total power requirements of the entire system, not just the GPU.
Apart from efficiency, it’s also worth considering the noise level, with some PSUs featuring fanless designs or quiet fans for a noise-free environment. For those looking to build aesthetically pleasing rigs, PSUs with sleeved cables or RGB lighting might be appealing, although of course these features should never be prioritized over the performance and reliability of the unit.
How much power does the RTX 4070 Super use?
The RTX 4070 Super has a typical power consumption of around 220 watts. However, when planning a build with this GPU, it’s crucial to consider the overall power requirements of the entire system: a power supply unit with at least 550 watts is recommended to ensure stable and efficient operation, especially under load.
