Intel introduces first new ATX Spec in nearly 20 years (ATX 3.0) with ATX12VO and 12+4-pin 12VHPWR connections- Just in time for RTX 3090ti next week

It has been in the works for quite awhile, but Intel is finally introducing a new ATX PSU spec. It sounds like ALL new <450w power supplies are going to have to abide by this spec or face higher component prices.
You mean > 450W and not < 450W, right? We'll get back to this part when you can clear up what you're trying to say here.

This new connector provides up to 600 watts directly to any PCIe 5.0 Add-in/graphics card. It also includes sideband signals that will allow the power supply to communicate the power limit it can provide to any PCIe 5.0 graphic card"
They're not signals. At least not the wires that the desktop cards will use. They're just sense grounds. Read Aris's write up on it. It has the table on there.

Please figure out how to use the > and < signs.

I can see a situation where 80% of Zen 4 (X670?) and Raptor Lake (Z790?) motherboards use the old spec with the 24 pin power connector, and the other 20% adopt the new standard. This is going to cause a really awkward transition phase where it is hard to recommend the route for builders to take.
Why? When you're building, you take into account the chassis (ATX? SFX?), the motherboard (ATX12V? ATX12VO?) and the GPU (6-pin? Two 6-pin? 6 & 8-pin? Three 8-pin? 12+4-pin) So this is no different.
What it WILL mean in many situations is you won't be able to shove your 10 year old PSU into your 4090 build. But hey..... You just spend $3K on a GPU! What's another couple hundo?

For sure? How do you come to this conclusion?

The 4090? is going to pull at a minimum >350 watts, so A LOT of people are going to be looking at new PSU's anyways, why not get the new spec?
Actually, 600W. Where did you get 350W from? LOL! And yes..... Why not get the new spec?

That would be a mess. But remember: The 12+4-pin is part of the PCIe 5.0 spec. PCI-SIG has the "old" 6 and 8-pin connectors anywhere in the 5.0 spec. So if they put something other than a 12+4 pin on the card, they're breaking spec and my guess is PCI-SIG won't let them say the card is PCIe 5.0.
