PCIe Gen5 12VHPWR power connection to have 150W, 300W, 450W, and 600W outputs
One cable to rule them all? Admittedly, it's a bit of a mess with the many combinations of 12V 6- and 8-pin power connecter headers for graphics cards.
"2VHPWR" is the forthcoming PCIe Gen5 graphics card specification. In its complete arrangement, the cable can handle up to 600W of electricity. In addition, 450W, 300W, and 150W modes will be available. New papers provide the format of the Sense0 and Sense1 sideband signals. When both signals are grounded, the GPU will produce 375W of power and a maximum sustained output of 600W. If those signals are open, the GPU will initially get 100W, with a maximum of 150W during load.
Several power supply manufacturers have already indicated that their initial products would be compliant with the new standard. However, when it comes to graphics cards, NVIDIA's flagship RTX 3090 Ti Founders Edition was intended to be the first to have this sort of connectivity. However, NVIDIA has not released any information on a probable launch date for this device since its unveiling at CES 2022 in early January.

450 and 600w cables just to power up GPUs seems to excessive to me...
Companies should be prioritizing energy efficiency, not the other way around.

Is the industry just following USB's example of making this stupid as hell?
One connector but many possible outputs is a terrible idea. It's one connector and it should have to do everything by design. Make it 600w minimum standard and be done with it.
Stop duping people with fake/deceptive specs. I can see it already - "PCIE gen 5 compliant!" - with 150w connectors/cables and the poor guy/girl with a 600w gpu.
Agreed. While the wattage label on the connector helps, not everyone is going to know the wattage of a GPU. With the old connectors, you didn't have to know; it either fit or it didn't. This will also either drive up the cost of cheap PSUs, or, they could be a potential hazard.
The average consumer is an idiot. "hUrR dUrR it fits and the computer powers on so surely it works!" except when they try to put the GPU under any load. I expect a lot of products being unnecessarily returned because of this.
Why couldn't this just be a 350W connector? Nothing more, nothing less. The PSU must deliver that wattage or else it shouldn't be included. At 350W, it doesn't have any overlap with the old connectors, so each one is still distinctly different. 350W is pretty much the upper limit of what can be dissipated in a dual-slot HSF card. If you need any more than 350W or a GPU, it's a stupid product, so just use a 2nd connector.

Single cable is a better solution than some 320W GPU that comes with 3 power connectors, are you gonna use 3 separate PCIe power cable for this (no piggyback)?

The most stupid thing is to make a GPU that need 600W when the whole world work hard to reduce the W used everywhere (exept crypto farmer)...
Oups... my bad... those GPU might be made for them, at least for those that left: if you want a sport car, a luxury sofa or even a well placed house (everything that is bling bling) right now they sell everything again...
