Question What power supply wattage should my computer have for a rtx 3070?

[rony2010]

For 3D rendering, I intend to create my computer with the B550 a-pro, Ryzen 5 5600x, and rtx 3070, along with a 1TB SSD and 16 GB of RAM. I don't intend to overclock.

Is my computer's 650W gold PSU enough? Is it sufficient to handle a rise in power consumption?

Should I choose 750W gold to be safe? or would 750W be excessive for my build?

*I've seen that 650w is what nvdia advises for the 3070. but I desire

750 might be better to account for any transient spikes. and room to move for future updates.

Just don't choose a cheap PSU as they may not provide the wattage they advertise. Make sure its 12v rail can actually run most of the wattage it advertises on box.
