Not sure why they didn’t just use 12v to start with.

I remember the first USB standards proposal with claims of “one cable for everything!” and diagrams showing a power cable from the wall to the computer, then a single cable leading out with T-connectors along its way to the monitor/TV, keyboard & mouse Mac-style, speakers and an external disc.

Dream 1. Then Version 1.0 arrived. 1.1. 2.0. 3.0 and still dreaming.

This new version will make Windows 50% faster, right?

The idea is to power more devices through just the cable… while that might be possible for some devices such as a computer monitor (assuming 75W consumption avg on brightest setting)-- most people will not realize all this power has to come from SOMEWHERE… and most power supplies in the market are NOT up to the task… if you start sending power through USB, there has to be a device to supply it… and if you do it through computers they will need to have the proper wattage well in excess of what’s needed… and these things are NOT cheap.

I’m kind of annoyed USB 3.0 motherboards and equipment are STILL so damned expensive compared to their 2.0 counterparts… that premium should have ended by the beginning of THIS year! Also, they will need to use a different connector for sending power… for some idiot will try to do it with a a 1.0 - 3.0 cable and start a fire…

For supplying the extra power, USB ports are powered via the +5V rail on PSUs, so it’s just probably adding extra power flow to that particular rail. Though I wonder if most higher wattage PSUs are able to handle one or a few of these high-powered USB connections…

I agree the connector head needs to be changed and the cables for the higher-powered need to be thicker. Personally I’d prefer that they over-engineer the cables rather than “just enough to get by”.

I can see it now…

“Body found in shower texting, not suicide”

Today, a woman’s body was found in the shower with her new USB 8.0 device being plugged in, charging, and when she fumbled for the soap, her phone fell and electrocuted her.

Car batteries and toasters, need not apply.

I foresee … USB4 powered laptops, charging USB2/USB3 tablets & accessories …

My corsair 750w tx has a 30a (150watt) +5 rail…(all good here…)
Though, I suspect they’ll have to eventually UP the standvy rail a bit-- those are nominally 1 - 3 amps…

Personally, I think the 12v rails are more useful… the new mobos should downconvert voltages as necessary. I’ve long thought +5 volts was a scam by battery companies to avoid using common battery voltages 1.2, 9, 12 volts which were in mass production and have been long held as cheap standards… I think most equipment using +5v are actually running at less voltage, but the +5 is the max voltage for CHARGING a device with a battery (usually lithium ion).

120V DC = Safe (by AS3000 standards) for external use.

Higher voltages = lower currents = lower losses = thinner (higher gauge) wires = more distance with the same gauge wires.

Lower Voltages = thinner insulation.

Designing a device to work with the right voltage helps, but you don’t want to voltage conversion circuitry spread out everywhere either. Voltage conversion is:

  1. Noisy if done wrong.
  2. Takes up valuable real estate.
  3. Not the primary task of any device.
  4. Just another thing to go wrong.
