I understand exactly what you were trying to communicate,

No, you didn't. Although I am perhaps guilty of not being explicit enough. Being perfectly explicit at all times isn't always great fun, though.

Computing power and electrical power are mostly unrelated.

I know. There is, however, a relationship between reading what people say and the ability to assess what they intended to communicate. The more you read of what they said, the more you might comprehend it.
I understand exactly what you were trying to communicate, a flawed analogy between Moore's law ie. the increase of computer performance over time, with the increase of USB power available at the socket. The former requiring a leap in technology, the latter simply requiring an adjustment of the standard specification to the cable and plugs, as the technology has already been available for decades and is nothing new. Computer speed is a prediction of future requirements, USB power is a lagging response to the increase in gadgets people are already trying to plug in at once. You only have to look at some of the Block Erupter rig photos to confirm this.

Well, at least the new standard will allow for powered hubs that can make use of the extra amperage on offer.

How the hell are they going to power 20A over multiple USB ports? That sounds crazy.

Progress always sounds crazy. Until it isn't! Grin

Lol, I remember discussing the original Intel Pentium series with my very first boss. Upon hearing I was looking at getting a 75 Mhz machine, he claimed: "You couldn't possibly use all that compute power!". I had a similar discussion with some idiot kid on my college computing course a few years later who claimed that it was literally impossible to use all the processing capabilities of an original Xbox console. Despite how stupid it sounded, I had to keep talking to him to check that he really meant what he was saying, and that he understood what he meant. He did. I expect he's not doing so well these days.
Computing power and electrical power are mostly unrelated. Perhaps if you were talking about the bandwidth of USB 3.5 it might be more relevant.  USB power is limited by the size of the cables and connectors, not by some magical Moore's law.

I don't think you are going to see too many vendors with 20A USB cables/sockets. The spec may say 100watts but that doesn't mean manufacturers are going to waste money implementing it on their motherboards! 25watt 5 volt cables might be realistic.


I think what they have planned is to deliver the 100watts at 20volts not 5volts, so it keeps the connector size manageable.

Will need a new generation of PSUs for this, no one has beefy 5V rails that get even close to this.

My power bill does not want more beefy psu Sad

But where are connection between power bill and new PSU Huh You say that like it will raise your power bill ?!?!

Every motherboard since....oh, P4 connectors appeared have derived most of the 5V and 3.3V from the 12V of the supply, using the power regs on the board. 

The newest OEM machines I got at work have PSUs that ONLY give out 12V - there's no other ouputs.  12V in to the board, and then the drive's 5v and 3.3v are off a connector on the board.  They're Fujitsu machines.

20 USB Eruptors can run on a single USB hub plugged into a USB 3.5 port, and the hub has no need for an external power source beyond that provided by the port itself.

So now maybe Jalapenos can actually be USB powered. Grin
