News ASRock Z490 Motherboard Features 10-Pin Intel ATX12VO Power Connector

So , assuming at least some other Z490 mainboards adopt this new connector scheme, now new PSUs are required as well...(short of some adapter harnesses of some type being included, perhaps...)

12VO is mainly for OEMs and the main reason for its creation is increased power-efficiency, I wouldn't expect it to become a mainstream aftermarket thing for many more years.

For 12VO to really take off, there will need to be 12VO updates to every major IO so most intermediate DC-DC converters and their additional losses can be completely eliminated. The most difficult intermediate rail to get rid of will be 5V since all modern external interfaces use 5V power by default.

Initially an adapter harness - would be most likely - and some most PS are modular- would be trivial top have a 10p to 10p included in the cable pack.

And what exactly make this stupid? Because it's from Intel? IF Intel mandates the move to motherboard manufacturers, it will be done. This type of thing has happened several time over the course of Intel/PC history.
Getting rid of -12V and 3.3V makes sense, but for 5V none whatsoever. Too many things use 5V and they are not going anywhere. For example 5V is main voltage for USB (and the only USB voltage excluding Type-C PD and non-standard extensions).

Sooner or later, we'll need completely new connectors to support higher speeds and that will be the opportunity to scrap intermediate voltages. Yes, that won't happen until 10+ years after those 12VO IOs become mainstream and we'll have legacy IO hubs along the way too for people who don't want to ditch their legacy stuff.

Actually 5V on motherboards with 12V only Power supply are obtained from onboard DC to DC 12 to 5V converters on the motherboard itself ... notebooks already use that for the USB ports , the power in is 19V in most notebooks.

I know. Still need to get rid of those extra DC-DC conversions or at least move them closer to the point-of-load for increased efficiency. Moving legacy IO to case modules as more native IO goes PCIe would also reduce motherboard clutter.

In an ideal world, the next-gen bus power specs should mandate 10-23V absolute limits with 12-20V nominal so systems can simply provide whatever is convenient and most efficient. It would also pave the way for an eventual switch to 20VO.

The last time Intel tried this was with the BTX format, and that went over like a lead balloon. The industry is too large now, for any one company to change it just because. There has to be significant benefits for the new format in order to convince the industry to break compatibility with all existing cases, and BTX didn't have any. Will this catch on? Certainly not the way it was implemented on these Asrock boards. OEM's are where this will have to gain a footing if it has any chance of success.

It isn't an 'if' with OEMs: 12VO was created to make it easier for OEMs to meet upcoming energy efficiency regulations. OEMs will effectively be forced to adopt 12VO as energy efficienty regulations tighten up. Once that has happened, it will increase pressure on the PCI-SIG, USB-IF and whatever others may still be relevant to come up with 12VO specs so 3.3V and 5V power distribution can eventually be completely phased out from new hardware.

It would be nice to get a 12VO PCIe spec that allows 150-200W, could take that opportunity to make whatever changes may be needed to the slot for improved structural and signal integrity.

Pray this stupidity doesn't catch on...
tHIS MOVE IS GOING TO IMP

This move is going to improve efficiency, PSU runs off a 12v rail anyways

modern psus have a 12v 3.3 and 5v delivery, it seems that they are offloading those capabilities to save on power distribution on the motherboards and improve efficiency. Buuuuuuut: Having to connect 5 differen't connectors to your motherboard to power CPU,PCIE, SATA, AND USB is going to be a little ridiculous, even thought the PSUs already have the capability the DIY community will buck because it will look like <Mod Edit>

Nah. By the time 12VO becomes mainstream, interfaces will have been updated with 12VO specs and separate power cables will only be for unusually high power devices.
