Intel Z690 motherboards remain to use 24 pin connector over ATX12VO

ATX12VO is not implemented into the Z690 chipset based motherboards for Alder Lake. The manufacturers seem to have moved away from it. The standard requires a new compatible PSU with a 12V connector with 10 pins, the dc-dc conversion from 12 volts to the 5 and 3.3V for, for example, disks and fans would now take place on the motherboard.

The new PSU standard offers increased efficiency and lower idle consumption. However, every motherboard manufacturer is required to make at least one model that can handle this new connector. In order to meet this requirement, a product does not have to be released, but it must be designed.

Currently the AsRock Z590 Phantom Gamin 4SR and the Z590 Pro 12VO that MSI showed off in a video are the only motherboards that support the 12 volts PSU. For Intel's approval, Seasonic has submitted its Focus GX 650W power supply. Perhaps We'll need to wait until the 12th generation Core desktop processors and motherboards, along with compatible power supplies, are released.

motherboards are busy enough, stupid idea to make them do more than they already do
with pcie 4/5 ddr5 memory etc.. I doubt you want voltage conversions circuits on the same board too, probably doesn't help with interferences
I don't really know but I had an engineer complain to me he had a 5nA leakage so yeah we're talking extreme sensitivity here
that's 0.000000005A lol

Ok.

People assembling rigs for themselves replace PSUs pretty rarely. This one will "justify" the price bump. Like if mobos weren't expensive enough.

I'd be surprised if an idle phone charger had more leakage.

You will need power cables from motherboard to power your hdd or ssdo_O And rely on motherboard makers to make good quality converters, enough power power ports. This will increase price on motherboards!

I'd assume that PSUs would still have 5v outputs. Just mobos would have them too. Because simplicity o_O
