I am having another of these very common nowbad feelingsabout these firmware controlled MCU based all locked devices...One more for the list ofincompatible ... certified .... works with... blahgizmos..PSUshttps://www.intel.com/content/www/us/en/newsroom/news/intel-introduces-new-atx-psu-specifications.html?wapkw=atx%20specificationI am even wondering if they will start tosellthese *** specifications.. like USB or HDMI close stuff... pretty sure PSUs will change radically since this..Paul

content: Thanks for the link, But there is no Public datasheet or PDF, I think they would sell it tooI hope I'm wrong too.

( MS included ) by early 2000sAnd late 2010s garbage I trade for better ones...they were actually a pretty good valuePauli always miss you

content: Here is the ATX 3.0 specification document:https://cdrdv2.intel.com/v1/dl/getContent/336521?explicitVersion=true&wapkw=ATXWasn't that hard to find on Intel's site.For anyone concerned about these new side-channel lines between add-in cards and the PSU, that they might facilitate lock-in or other restrictions, etc, don't worry. They're just dumb status signals. There is no serial communication protocol.TheSense0&Sense1lines are just a 2-bit hi-Z/gnd (i.e. 1/0) value combination that indicates the maximum power output the PSU can offer. TheCARD_PWR_STABLEis an optional open-collector status output from the card to the PSU indicating that its local power rails are within normal limits. TheCARD_CBL_PRES#line serves as a primary basic function as a simple presence-detection flag for the PSU, via the card grounding the line. Secondarily - and this is only my interpretation, as the wording in the spec is not detailed, and I'm no expert on PCIe, so I might be wrong - it also can serve as some kind of output from the PSU to indicate to the card (by driving the line high?) that it has been included in power-budgeting allocation, which ties in to some kind of flag register that the card presents on the PCIe bus.All this is in section 3.3, page 26.

content: made a quick and dirt pass on the pdf...Looks promising ... although uncertain in what level these PSUs will handle now digital com..They will certainly cost a substantial plus due to MCUs requirements...Hope to see some chipsets already bundled with whole requirements...Paul

content: and BTW..If these new generation "consumer desktops" and "corp. kiosks." .will REQUIRE 170 TDP for CPU and at least 350W for a mid level GPU...Put a bestial cooler consuming for 50W and some other gizmos..Barely 600W will fit the job.. daily ON ..https://www.techpowerup.com/293253/amd-ryzen-7000-series-raphael-processors-to-come-with-up-to-170-watt-tdp-for-16-core-skus170TDP is almost double the oldest 90/95WPaul

content: Quote from: PKTKS on March 24, 2022, 02:32:25 pmThat is not the same thing as closed specifications. Which they are not, nor are the ATX specs. Complying with them requires having a unique ID, having a unique ID in any address space no matter how large requires coordination, and when the address space is limited, deterrence from waste. This requires staff, who require paying. The standards require engineers, technical writers, proof readers, and so on and so forth, who require paying, or they don't get developed.The specifications are open. You may reference them, you may implement them. You may choose not to comply fully and take the risks upon yourself if you sell a product.You never miss a chance to be wrong, hyperbolic, or just plain daft.For example:Quote from: PKTKS on March 24, 2022, 06:31:18 pmA top of the line 16-core CPU having a 170W TDP is not 'requiring' such capacity of any regular machine or its component parts.

content: Quote from: PKTKS on March 24, 2022, 06:31:18 pmUmmm... Some of the most common corp desktops use 25/35/65W TDP CPUs with integrated GPU. In fact they often use laptop power supplies instead of any ATX variant. Low power systems are not going away, they are incredibly common. At the same time, larger GPUs and other add in cards can now require more power than is practical with current ATX standard. Thus there a new ATX spec that has an optional connector that can supply up to 600 W to a PCIe card, and furthermore is can be made with multiple power levels and signalling of the current capacity to the device so that it is not required to have a >1 kW supply for a system that only uses a low end discrete GPU.There is no conspiracy here. This is just an update to a standard to meet needs that are already here.
