Intel Introduces New ATX PSU Specifications

JonChesterfield 5y ago
Includes a revision on the 12V only one that I'd dearly love to take off. Running a PC on a misc 12V supply instead of also having to cobble together 5/3.3/etc at much lower wattage seems much better.

  Seems like 20v might be a better choice. Then you have 20v available for USB-C monitor ports. You could give every device its own modular swappable mini PSU that takes 20v and gives whatever the card requests, so if the onboad converters go bad on a GPU you can swap them. At least it seems like negative voltages are mostly on the way out!

5v everywhere, job done.

What caught my eye was the new spec includes side channels for the PSU to communicate with add in hardware. Specifically to report the PSUs capabilities. This looks like a red flag to me. This could be used as a way to vendor lock certain features of hardware to certain brands or capacities of PSU. Get ready for DRM that checks your system all the way down to the PSU level. I prefer a dumb PSU that just gives up the magic smoke rather than narc out the fact that I'm pushing it over is limit.

  Nono!Think about the added value of integrating that with your smart-meter, to have power plan prices communicated via proprietary protocols, and integrated with Office 365 for terrific teams, or something like that.

  Uhh the red flags were there in 1997 when you all started buying client-server software. Intel and the industry know you are idiots at computers. MMO's/steam are signs of idiocracy, aka you are bad at understanding you are getting robbed. That's why we have TPM and client-server crapware in windows 10/11. If you buy any client-server SaaS you are a moron, everyone was expecting local applications forever until 1997. Even EA would have never imagined you'd all be dumb enough to buy incomplete programs where they take files hostage on a 2nd computer half a world away. So no the time to be alarmed was over 20 years ago, since there is no software or game that requires an internet connection, there was no steam, no stupid fucking login screens, nothing. The public has told the tech industry it is chimp factor five levels of stupid over the last 23+ years. So they are locking us out of our PC's, windows 10/11 is building copyright enforcement into the cpu so future applications won't run and your bios can be remote updated like a console to disable any pirated software or cracked exe's that are found on your PC. You all gave them this access to your PC, so why wouldn't intel and the rest just keep going? See here on EA and ultima, and the death of games as local applications: https://youtu.be/lnnsDi7Sxq0?t=1134 https://youtu.be/lnnsDi7Sxq0?t=1134

Cool, but where is the actual spec? Can't seem to find it...
- adrian_b 5y ago
  The actual specifications do not seem to be published, but Intel has published some design guides for ATX 3.0 and for ATX 12VO, which contain most of the information about these: https://cdrdv2.intel.com/v1/dl/getContent/336521 https://cdrdv2.intel.com/v1/dl/getContent/336521 https://cdrdv2.intel.com/v1/dl/getContent/613768 https://cdrdv2.intel.com/v1/dl/getContent/613768 https://cdrdv2.intel.com/v1/dl/getContent/621484 https://cdrdv2.intel.com/v1/dl/getContent/621484
