Point in case, I have a newly built Ryzen 5900X tower that reuses a GPU from an old build. I chose a high quality 80+ Platinum 750W PSU thinking that would give more than enough headroom for upgrading the GPU at some point, but if the next generation of GPUs are as power hungry as rumored I’ll be limited to current generation cards unless I buy a new PSU.
I hope efficiency comes to be a focal point again soon, because if the trend continues you’ll need a 1kW PSU just to comfortably accommodate current enthusiast parts and have any hope of upgrading in the future, which is ridiculous.
