The amount of video storage is irrelevant for power consumption.

How much watt psu for a 4 or 8 GB graphics card?

Find out a graphics card you like and then look at the manufacturer’s website for which power supply is recommended.

This is the simplest method.

The required wattage for your PSU (network) depends on the entire system configuration, not only on the size of the VRAM of your graphics card. In general:

  • For a 4 GB graphics card: A PSU with 500 to 600 Watt lasts for most systems if you have no particularly powerful CPU or other components.
  • For an 8 GB graphics card: Here you should 600 to 750 Watt plan, especially for more powerful GPUs (e.g. an RTX 3070 or the like).

If you take into account your entire hardware (CPU, drives, additional components), you should choose a PSU that offers at least 20-30 % more power to stay stable even at load. A 750-Watt PSU would be a good choice for future upgrades.

If only volts and amperes stand on it, just calculate. Usually stands on the PSU. Maybe the Watt value.

This can usually be seen on the label on which all information as well as manufacturer and model name are printed.

and only at the edge, because it appears in the above answer….

PSU=Power Supply Unit -> Power Supply Unit! Consequently, not “one”, but “one.”….

Your answer is in principle not wrong, but the middle part (i.e. with 4GB and 8GB) is better. It’s just bullshit what you know yourself. There are old, current-sucking graphics cards with 4GB and also modern 8GB cards with low power consumption. Both graphics cards accordingly place different requirements for a power supply. So you can’t flatter here.

How much memory the graphics card has no role.

Only and alone how much power (data in Watt) the graphics card needs is important.

If you want to go easy, you can use this power adapter: https://www.bequiet.com/en/psucalculator

Enter all your components and you will be charged an emptied power supply.
