Hello, I put together a basic presentation, it needs a lot of work still, but this is just a first pass.
Definitely still working on things and will be getting more videos out soon.
The basic idea is that using many non-pfc adapters on a system versus using a high pfc adapter on a system changes the performance of the adapters even if on paper analyzing one device looks far better.
This applies to offices and places where multiple power supplies are strung together more so than other systems. Lighting systems mostly took care of this already with very good performance across that industry but power adapters, which keep increasing in wattage, don't seem interested. This can apply to your household as well, but the effect is smaller as the many devices are spread across more circuits. The calculations are not complex but tedious so I think the general rule is 'it's good enough'. The question is, is it worth getting the last few percentage points of efficiency out of systems?
Let me know if you think this should make it's way to a video or something similar, probably made generic, and well, finished, ha. Let me know if it is helpful in any way and what should be added or removed.
