    its feasible if they are dumping support for SATA and going ahead with consumer SAS,

    Anything that removes clutter, but no features or performance is a win in my book.

    Let me guess, every new intel processor will require a new PSU plug now too eh?
    /sarcasm

    I have often wondered if the 24pin connector was necessary, I'm just betting it'll take forever for a change to actually happen.

    motherboards are going to get more expensive.

    Because the motherboard will only take 12V , DOES NOT mean the psu won't be able to deliver 3.3 or 5 V for perhiperals like ssd and rgbstuff.

    My fingers will be happy when this happens. Don't know about you guys, but for me the 24 pin is always a pain to work with. When I build my latest Ryzen rig, and had to take out the old X99 mobo it took me like 5 minutes to get the damn thing off. It became so stiff and almost glued, that I was sure I'll end up ripping the mobo apart. I mean, I had problems in the past, but not quite like this last time, lol. :oops:

    To be honest I don't care much about the cable count, it's just the connector that is really bad...
    Otoh, if it somehow helps increase efficiency (for any psu, not just super cheap ones) then bring it on.

    Edit: just read a bit more. This should be integrated with new SATA cables that include power. Having 2 cables per device going out of the motherboard is not nice. Specially since each manufacturer is free to put such connectors pretty much anywhere on the board which conflict with case design.

    Pretty much all PSUs today first convert 100-240v AC to 12V DC, then obtain 5V, 3.3V with DC-DC converters inside said PSU.
    But to be honest this is a good move, Laptops have been powered by 19V DC (most of them) for quite a long time, and they do every other conversion internally ( after the battery regulation ).

    If these things fit in a slim case of a laptop, it won't be an issue whatsoever to do so on a desktop-sized computer.

    ... the question is, how long it will take to actually be put in practice.
    AT to ATX took many years to happen, I'm guessing ATX to 12VO will be even longer.

    ---
    p.s. You know what I would find interesting ?

    To devise a standard for a PSU with a connector in which you can plug a lithium battery pack (also standardized). I'm fine with only high-end PSUs having it...

    It would make normal desktop computers behave like laptops, just buy a battery pack and attach to it, internal battery backup for power outages, brownouts, spikes etc.
    No fear of unexpected shutdowns and data corruption...

    Also, the powered "standby" mode would work nice, keeping data in RAM for Instant-On, even if the computer is unplugged...

    Yes of course, there are external UPSs, but those are inefficient, heavy, loud, have that giant transformer... as they have to deal with the high AC voltage.
    This PSU-based battery solution would be slim and elegant, only working at DC levels (12V), and a 13.4V LiPO battery pack can be small and theoretically cheap... as they already are in billions of laptops and other mobile devices.

    One can dream...

    Yeah Corsair Type4 cables with some extra thickness to them and getting the cable management to look good and plugging these in with the twist/bend/orient gymnastics that is certainly a challenge though at least the cabling can take it but once it's fitted it's going to remain fitted in, forever. :p
    (Well removing the end bit from the PSU is a thing at least should it ever be required.)

    EDIT: Course a straight line from the PSU to the socket also works, cable management pfft.

    Any change that makes more space available on the mobo is a good change. That 24pin thing is just archaic and a monstrosity from decades ago.

    In industrial PC most motherboard supplie the 3.3v and the 5v, PSU are already only in 12v (because it is one of the standard ).
    The bad thing is that yes, motherboard are generaly more expensive.
    As a lot of Intel's "improvement" it will work Only if people adopt it... I don't think it is already won...

    Anyway, adaptator will exist, i still have a PSU with 20pin and only molex that still work with 24pin and SATA adaptators for my spark/injector program.

    I have seen this all ready on prebuilt from Fujitsu and Dell, maybe this is not new at all, just not a standard.

    Looks good to me. The old, humongous connector doesn't fit this decade anymore. In fact it should have disppeared 10 or 20 years ago already. It's ridiculous that thing is used for nothing but to deliver power to the mobo, and not even all of it these days because the CPU got its power elsewhere. You'd think a couple of those wires could at least be used for communicating with the PSU for monitoring info, not just for the power on status, but nah.

    Original ATX spec was only 20pin. We didn't move to the 24pin connector until 2004 with the ATX 2.2 spec. Not quite "decades old" yet....and 10 years ago there was little reason to do away with it, as the ATX2.2 spec was still relatively new. 20 years ago, we were using a 20 pin connector...

    ive imagined going full DC after eventually getting enough solar panels and batteries, so like 12v wall outlets, and wondered about what to do with my pc and its complicated PSU, now i see thats probably getting addressed later on, and eventually everything will run on usbc, that means almost every device will accept 12v power through it, pretty cool, no more dc>ac>dc

    Actually, it would have been precisely the perfect time to get rid of it, to replace it with a more handy connector, instead of adding more wires to it.
