USB4 2.0 Cables Capable of 80 Gbps Data and Power Delivery of 60 W and 240 W, Get Certified

With PC motherboard manufacturers implementing 40 Gbps USB4, one wonders what's next for the [mostly] universal connectivity standard. Turns out, it is USB4 2.0, which yields the connector 80 Gbps of data bandwidth per direction, and 60 W of power-delivery (PD). Power delivery for USB4 2.0 can be as high as 240 W (48 V, 5 A). Japanese PC peripherals maker Elecom is the first with certified cables for both 80 Gbps + 60 W PD and 80 Gbps + 240 W PD. Besides power and data, both cables support DisplayPort passthrough for up to 8K @ 60 Hz (7680 x 4320 pixels). USB-IF, the governing body of the USB standard, is expected to formally launch USB4 2.0 in December 2024. A typical USB4 2.0 host controller will require at least a PCI-Express 5.0 x4 system bus connection to reach the standard's maximum bandwidth.

The USB-IF needs to be taken to pasture. The only explanation for asinine naming, and even the plethora of different implementations all under the same name, is insanity.

USB4 2.0... I thought they were using the 'Gen2x#' moniker?
Guess I'll just pedantically memorize the latest USB-IF nomenclature :rolleyes:

The biggest missed opportunity in the past 8 years of USB is not being able to link and daisy chain fans and RGB devices together with USB.

48V at 5amps :D in Usb port :D
Not gonna use that from my PC obviously.
I only use external charger for my phone or whatever i use.
Speed should be only maintained not power delivery if u ask me.

I hope they name the next version 4.1 and it's gonna be better than 4-2.0

Does anybody know if that 80Gbps can be fully used? For example, with Thunderbolt3/4, they advertise 40Gbps, but in reality if you hook up an external SSD or an eGPU, it is only using 32Gbps....that other 8Gbps is used by things like Displayport protocol, but cannot be accessed by the devices I mentioned above. Is it the same way with USB4 and USB4 2.0? If you hook up an eGPU to a USB 4 2.0 port, is that eGPU going to have access to the full 80Gbps or will it only have 64Gbps or something lesser?

Current: USB4 Gen3x2 cable (40 Gbps)

But now USB4 2.0 Gen1x1.. or is it USB4 2.0 Gen3x2? Gen4x1?

Why USB version 4 2.0 Generation 3 ??

Universal Serial Bus 4 version 2.0 Generation3x2 Power Delivery 3.1 240 watt.... Even the Welsh are laughing.

They changed that with USB4 2.0, we now have:

The USB-C connectors are too expensive to do that.
All the other connectors are only allowed on one end of the cable to be allowed to be called USB.
That said, there's no-one stopping you from doing it, it just wouldn't be something approved by the USB-IF.

USB4 already allows for the full 40 Gbps to be used.
I wrote about this over two years ago, but clearly no-one that is a regular TPU reader, read my article.

USB4 1.0 and 2.0 also uses tunnelling for all the protocols, but DP is the one being prioritised when in use.

No, see above.

USB PD is a separate standard, USB4 only has a minimum requirement of 7.5 Watts (as I**** didn't want it to compete with T**********) but it seems like most motherboards do at least 15 W.

Indeed. I was shocked on the first read thinking "How can USB 2.0 ports all the sudden support that speed?"

I missed the "4" snuck in there.

More nonsense nomenclature

This is the only system we need:


etc...

If they do PD, then that should be clearly stated on the ports and cables in Watts, not hidden behind some bullshit lookup tables of USB version, sub-version, and bogus caveats* or using the words "up to" everywhere. I can type at "up to" 300 words a minute and my monitor's pixel response is 1ms*



Why is that so hard?
