Asus details power demands of RDNA 3 GPUs – and they may not be as much as you think

Asus has provided official power supply requirements for those buying a new RTX 4080 or 4090 graphics card from the company, and also the necessary wattages for those looking at purchasing an RX 7900 XT or 7900 XTX when those RDNA 3 cards emerge in December.

Bear in mind that the stipulated PSUs for these graphics cards do depend on what CPU you’re running them with, as these days, some processors can demand a whole lot of juice from the power supply too – so whatever combo you have in your PC , you must bear that in mind.
