This is because the RTX 3070 is a high-performance graphics card that requires a lot of power to operate.
A 650W PSU is capable of providing enough power to the graphics card and other components in the system, while also allowing for some headroom for future upgrades or overclocking.
It is important to note that the actual power consumption of the RTX 3070 can vary depending on the specific model and other components in the system.
However, it is generally recommended to follow the manufacturer’s guidelines to ensure stable and reliable performance.
Is It Possible To Use A Lower Wattage PSU For The RTX 3070 If You Are Not Planning To Overclock It?
NVIDIA recommends a 650W PSU for the RTX 3070.
However, it is possible to use a lower wattage PSU if you are not planning to overclock it, depending on other hardware in your system.
For example, a 600W PSU might be sufficient for a system with an RTX 3070 if other components are not too power-hungry.
It is important to note that an old or underpowered PSU can cause issues, regardless of its wattage.
If you are upgrading your system, it is recommended to choose a high-quality PSU with sufficient wattage to ensure stable and reliable performance.
What Are The Consequences Of Using A PSU With A Wattage That Is Lower Than The Recommended Range For The RTX 3070?

While it may be safe to use a lower wattage PSU under certain conditions, it is generally not recommended.
On the other hand, using a higher wattage PSU than recommended is generally safe, but it may not necessarily result in more power or better performance.
Is It Safe To Use A Higher Wattage PSU Than The Recommended Range For The RTX 3070?
According to various sources, it is safe to use a higher wattage power supply than the recommended range for the RTX 3070.
The wattage rating of a power supply only indicates what it is capable of, and actual power use is determined by the computer’s power requirements.
It is generally advisable to have some extra headroom in case you want to attach additional components later, and most power supplies hit their peak efficiency levels with loads in the range of 40 to 80 percent.
However, it is important to get a reliable and efficient power supply, and to avoid exceeding the capabilities of the power supply.
