Alder Lake peak current allegedly 28% higher than Rocket Lake 
www.tomshardware.com
If true, that's getting beyond ridiculous.
While 11600K is fine, 11700K is already pushing it for my tastes for all-core loads (non gaming) and 11900K is already rather ridiculous. Going beyond that isn't something I'd want, considering how crazy the GPUs already are at peaks-power. Now we have:
Yeah, I know it's peak power only for 10ms or so, but even "65W" CPUs will just not work with many older PSUs (even if rated for quite high watts) as over-current protection will just kick in at 30A.
So coupled with current 300W+ TBP custom GPUs you'll need a quality gold+ 1000W PSU or better for a new gaming rig. And be ready for the CPU to draw 250W, sustained, at times.

Cranking up the juice

The peak output for the 125W SKU increased from 34A (408W) to 39A (468W), while the 65W SKU went from 30A (360W) to 38.5A (462W). Even the energy-efficient 35W SKU jumped from 16.5A (198W) up to 20.5A (246W).
