It may be true but lately AMD/Intel/nVidia use the better performance-per-watt ratio to increase performance and not deliver products consuming less power. At best, new buyers end up with products at the same consumption. At least for the high-mid-range/high-performance parts.If you're concerned about power consumption, then wait a few months before upgrading. Especially when it comes to GPU upgrades.
The 3080 is 2 years old & it's sucking freakin' 320W from the wall! Next gen GPU's are around the corner & AMD already anounced a 50% better efficency. They also anounced a 25% better efficency for their Zen4 CPU's (as well as 35% performance increase):
"AMD RDNA™ 3 gaming architecture that combines a chiplet design, next generation AMD Infinity Cache™ technology, leading-edge 5nm manufacturing technology, and other enhancements to deliver more than 50% greater performance-per-watt compared to the prior generation."
“Zen 4” CPU core expected to power the world’s first high-performance 5nm x86 CPUs later this year. “Zen 4” is expected to increase IPC 8%-10%1 and deliver more than a 25% increase in performance-per-watt2 and 35% overall performance increase compared to “Zen 3” when running desktop applications."

You could get a AMD 7700 XT which might be on par in performance with the 3080, but consumes 120+Watts less. It will also be cheaper than a 3080. Zen4 will also be quite more power efficent, and AMD's upgradeability is also way better than Intel. Other than that, like others already mentioned, undervolt your CPU & GPU. If done right you'll save power & even gain performance. And use a frame limiter!
So I wouldn't expect much on total power consumption
