New graphics card power plug for up to 600 watts is coming (12VHPWR)
Graphics cards are becoming more powerful, but they are also becoming more energy-intensive. A 450-watt power delivery is expected for the GeForce RTX 3090 Ti / Super, which is expected to ship in early 2022 - and that's not all, a new power plug is required to make this happen.
The GeForce RTX 3090 Ti, will be released in January of next year and will use up to 450 watts, 100 watts more than the current GeForce RTX 3090. When three 8-pin power plugs are used, the power consumption reaches its maximum of 450 watts, which is also the maximum allowed. As a result of the possibility of even faster custom designs, and particularly in light of the next-generation GPUs Lovelace and RDNA 3, something new is unavoidably required, because even more 8-pin connectors are difficult to integrate sensibly from the onboard design alone.
In order to avoid ambiguity, the GeForce RTX 3090 Ti should include a proprietary power connector comparable to the Founders Edition of the GeForce RTX 3000 series, but .. bigger. It is a new 16-pin Microfit connector will be known as the “High Power Connector” or “12VHPWR” by the PCIe SIG for the PCIe 5.0 standard. The name is literal, as the plug should deliver 600 watts. The plug can deliver up to 600 watts at a constant 55 amps, and theoretically up to 662 watts.
Amphenol ICC is the first manufacturer to have inadvertently revealed the new power plug, as it is now visible on the website, and the suspected specifications are now confirmed. There is additional information regarding “4 signal contacts” on the connector on the bottom.

i'm struggling with the up to 350 watts think my card jumps too... had reduce power on it to keep it under 300 watts most the time, going past 400 seems insane to me... nice heater in the winter months at least xD

This higher tier GPU power consumption is geting out of control past few years, if someone asked me about GPU power consumption lets say 5 years ago I would thought complete opposite would happen. Wouldn't be surprised if some retailers starts offering these GPUs bundled with discounted ACs in summer season

At least those who buy these can be proud that probably there is no better looking 650W room heater when winter comes... and probably there is not more expencive one out there

So, if both Nvidia and AMD create their own "standard" power connectors, they also need to always include adapters with the cards. Maybe in the future the responsibility will fall into the hands of the PSU makers, who will either need to supply the units with two different sets of cables or adapters. Adapters would create less e-waste, but would look worse for those minding their cable management.

This is what happens when you have tight competition. Only way left to achieve top spot is by turning up the power. Wait till Lovelace arrives when 600w + becomes the norm.

If Nvidia and AMD are really going to building cards that use up to 600 watts, I certainly won't be buying in the upper echelon this time round. This is starting to get out of hand, I find it hard justifying the up to 450 watts my current card can use.
