USB-C upgrade will more than double its power capacity to 240W

Thanks to its compatibility with a range of devices, USB-C is the prime candidate for a common charger that could help alleviate the build-up of electronic waste. So, news of a major power upgrade bundled into its new standard will only boost its case. As CNET reports, the version 2.1 update to the USB-C specification could deliver up to 240W of power, more than double its current 100W capacity. The change would allow you to juice up beefier electronics like gaming laptops and larger monitors.

Not to  sure I see that happening with a lot of built in USB-C ports. Could you imagine a board trying to power everything? for example, TRX40 AUROS Extreme offers support for 2 built in USB-C ver.2 (1 on the board & 1 on a header)Upgrade that and you have a possible 480 w drawing from the board before you even count the default 280 watt for the cpu.Then add in drives,ram,ect. and I think you can see why I think it'll be more in use for single external chargers.we'll still be powering the monitors with the seprate brick.

...and then add a 500 W +- Ampere 3090 on top ?

It's sounds nuts to put 12A through a USB-C connector. Impressive if it can be done, but it seems like a bad idea if you consider the size of the contacts compared to something like PCIe Molex connectors.

EDIT: derp. it's 48V, not 20. Only 5A

Kinda OT, but I thought this was pretty wild. It's a 48V to 12V 1KW GaN buck converter that operates at 1MHz. Because of the high switching frequency, the PCB traces can be used as the inductor "coil", with a ferrite block attached directly on top of the PCB.

Impressive. Though you would have to watch out for poor quality versions of such a cable as I can foresee a fire hazard for those skimping on things like appropriate wire guage.
