Default New PS regulations coming into effect soon

As of Dec 2020 all external Power Supplies for A/V equipment will have to meet new levels of efficiency, in particular idle current draw. A good summary can be found here:

New External Power Supply Standards: 62368 to Replace 60950 and 60065 | Power Electronics

This will have the probable effect of eliminating linear supplies (in favour of switch mode variants) with commercial A/V and might cause the remaining linear supplies to be eliminated from supplier catalogs.

Very useful information. When I read around, the IEC62368 should mainly be concerned with "hazards" (safety, I assume) but it also includes efficiency (environmental concern; you may call that a hazard as well)?

The title of this thread might be a teeny bit misleading(?) - see the external in the title there?
That's (only) wall-warts, in layman's terms. Those, and power bricks (laptop chargers, external power supplies for slim displays etc).

From what i can read in that article (and there are a LOT of mentions of "external"), this won't be covering the big fat iron you'll find in 5.1-7.1 AV receivers / home theater amps More like only the always-on stand-by supplies in those.

But then again, how often do you find "iron" wall-warts being supplied with A/V equipment nowadays anyway? Those will be low-power devices anyway (the ones above that may well have the power supply built in).

If they were really concerned about the planet they'd outlaw mining of bitcoin. 32TW annual power consumption.

Whadda mean? Why can't we just build a ring of Nuke Generators
and go to work. Talk about wealth creation.

Transformer power supplies meet the efficiencies required.
SMPSUs however will need to meet power factor requirements and have adequate filtering in the mains input side to stop interference ingress in the mains supply.
The UK already meet all requirements of the USA codes and have done for many years.

Definitely they do not. Pls have a look at standby power consumptions according to DOE-level VI, for instance.
