100W Power Delivery Spec Approved For USB 2.0 And 3.0

Quote:
One of the biggest pet peeves in a technology enthusiast's life is the plethora of proprietary power cables that plague the consumer market, each with a slightly different design. Can't we all just get along and charge via USB? That utopian vision took one step closer to becoming reality yesterday, as the USB 3.0/2.0 Promoter Groups announced a USB power delivery spec that makes the every-port capable of delivering up to 100W of pure power. Yep, your PC can now charge a notebook. Heck, a laptop could even theoretically charge another notebook.

Wow... I could even be happy with 50W only... this wil surely fix problems with external disks it seems...

But there is something they are not saying here, are the MotherBoards capable of this?, I mean, the "onboard" usb ports are able to deliver such amount of power taken from the PSU?

Probably not. Newer MB's may adopt this new spec, if they think it is worth the trouble, but it may take a few years. Also the PSU has to be able to supply the extra power on the 5v rail.

Ha... I knew it... but this will requite entirely new technology for MoBos then? bigger capacitors?... looks like a good amount of power to take care of... maybe about my PSU I won't need to worry as I got 22A on the 5v rail (gives 110W according to multiplying laws XD) and I certainly only use few, but powerfull USB devices...

Well, seems I need to wait until I think on replacing my current MoBo...

I wonder if this would require an additional rail on the Mobo for this power?

I got plenty of power on the 5 volt, 25A and 180W. I have been trying to find the spec for the motherboard and so far no apply pie. The idea sounds very good. I don't know if knowing the exact specs of the motherboard really maters. It should be made for any USB device I know of. It seem like the big bottle neck is cabling. I think it's a great step in the right direction and it shouldn't cost to much.

100W at 5V is 20A. I don't see how the contacts in a USB connector or socket, not to mention the cable, could take that much amperage without releasing the built in smoke.
