My hunch is there is a max and a min - but not at all clear in the Computer form factors box.
If a standard has a max and a min it should be listed as 123 x 234 - 111 x 199 — Preceding unsigned comment added by 108.243.106.82 ( talk) 22:45, 22 April 2014 (UTC)
According to the ATX12V 1.1 power supply design guide this is only required for power supplies with +3.3V output greater than 18A or +5V output greater than 24A. Does anyone have a copy of the ATX12V 1.0 spec to confirm if this is the case there too? Plugwash ( talk) 11:05, 1 September 2010 (UTC)
A 8 pin aux connector is required by Intel Core processors, that is often meantioned as being ATX on recent power supplies. If this is gona be ATX standard it has to be watched ,right now the ATX standard doesnt meantion this or? Is a meantion in the article worthwhile, that the ATX standard is extended like that? 79.238.253.112 ( talk) 18:10, 29 January 2011 (UTC)
This section seems to be slightly outdated. EVGA has already released its HPTX motherboard (it's called EVGA SR-2 I guess). —Preceding unsigned comment added by 81.200.20.83 ( talk) 19:27, 18 April 2011 (UTC)
I created this ATX-2-AT adapter assignement table. Maybe it could be useful? It's not fully completed. I tested it anyway, and it works. I did notice however that the "not connected" on the ATX connector is used for -12V in some cases (FSP Group Inc). Something to watch out for perhaps. Electron9 ( talk) 01:11, 19 June 2011 (UTC)
I doubt that this will have a tremendous impact on the article even if it goes ahead, but for form's sake I have proposed that HPTX (Form Factor) is merged into the existing coverage of the form factor here. I you want to comment on this proposal please do so on that talk page rather than fragmenting the discussion. Crispmuncher ( talk) 21:24, 7 July 2011 (UTC).
The power switch section says "While this switch functions as if were a physical switch and disconnects AC power from the power supply (as required by UL),", but this cannot be true: the entire 5V-standby circuitry remains powered on and thus the AC must be present. Apart from the wasted energy this also poses a significantly higher risk of damage by voltage spikes on the line. Considering that most home users will neither use WoL or power on by keyboard, but also will not go through the trouble of using the back-side switch (if present), this means higher risk (and cost) for negligible gain.
The reference to an UL requirement has no citation, and I don't see how such a requirement could be accommodated while maintaining standby power. I have not yet modified the article in case someone does find a proper citation. -- 93.201.252.230 ( talk) 12:45, 14 September 2012 (UTC)
I know Wtyshymanski is gonna chew my ass out over this, but I really think part numbers for the connectors belong in this article. Mainly because the connector manufacturers do not make any attempt to declare "this part is what the ATX standard uses" in their product descriptions.
To them it's just another part in a series of theirs, which someone ELSE declared part of some global interconnect standard. Yawn, is that their concern? Apparently not.
Just try searching for the ATX socket part number and see how far you get. Apparently only Molex makes it? Does AMP make a compatible connector? Who knows. That's the sort of detail this article could use.
Also, just try finding the 20+4 motherboard adapter plug assembly with the 4 breakaway pins, or the 24 pin socket intended to mate with the 20-pin plug or 24-pin plug. Finding the part numbers for these ATX components is a nightmare. DMahalko ( talk) 22:01, 28 October 2012 (UTC)
I see a lot of documentation on what wire carries how much volt. How much amps do they usually carry?
I know it depends on the PSU wattage, but an average would be nice (eg: For a 500W PSU). — Preceding unsigned comment added by 74.166.176.82 ( talk) 06:29, 21 January 2013 (UTC)
I originally marked the 13 amp rating for the MinifitJR connector as dubious. It is only 8 amps per conductor with 18 Gauge wire, 24 pin connector. I have now corrected it based on this document: [1] I found a (broken by JavaScript) link to it on the cited page (cite note 11). They may not like hot-linking. 70.74.233.146 ( talk) 17:17, 22 March 2014 (UTC)
Mini ATX could mean either 284*204 or 150*150mm. The ATX comparison picture uses 284*204mm, the table uses 170*170mm. 2001:980:A381:1:754F:42C2:1603:EA96 ( talk) 15:42, 24 January 2013 (UTC)
See File talk:ATX PS signals.svg#Possible error. Wtmitchell (talk) (earlier Boracay Bill) 23:10, 16 April 2013 (UTC)
Has anyone information on the ATX 2.4 specifications? — Preceding unsigned comment added by 79.247.147.103 ( talk) 19:54, 12 October 2013 (UTC)
Some versions of the Intel ATX Specification (i.e. Version 2.2) contained a small, but important, typo on the Main Power Connector drawing (figure 8) from which the Wiki drawing ( http://en.wikipedia.org/wiki/File:ATX_PS_signals.svg) was sourced. This has been corrected in the current Intel spec. (i.e. http://cache-www.intel.com/cd/00/00/52/37/523796_523796.pdf Section 4.2.2 figure 5), however the Wiki drawing has not. The error is that "PWR_OK" is shown as "PWR_ON". Since there is already a "PS_ON" signal, this is confusing.
Note that the official specification calls this signal "PWR_OK". "Power good" was IBM's term for the signal as used by the IBM PC, and the ATX spec references it (in quotes) as a class of signal. It's proper name is "PWR_OK" (section 3.3.1, http://cache-www.intel.com/cd/00/00/52/37/523796_523796.pdf) — Preceding unsigned comment added by 108.213.76.24 ( talk) 17:03, 4 February 2015 (UTC)

This layout current lacks, maybe "internal rhythm" - some sections have no more than 1 line of text, others have a pile. This makes it hard to put all the minor variations into a table. Maybe a table to absorb the minor variations and make it easier to compare features like dimensions and number of slots, and then a following narrative section that would explain more of the "why" and "wherefor" reasons for the major changes? -- Wtshymanski ( talk) 16:29, 29 May 2017 (UTC)

According to Gamer's Nexus, E-ATX is not a standard, it is free-for-all marketing thing that generally agrees largest size is 12" x 13". Wikipedia article has inaccuracy referring E-ATX and SSI EEB are not hole compatible which is untrue. SSI-EEB only introduces additional POSSIBLE hole choices to make component placement easier on the motherboard. [1]
(Different user here:) I have some information to add (I wish I had more time to contribute in amore meaningful manner, but - take it for what it's worth). One of the first and most-prominent motherboards to support the AMD Socket sWRX8 for AMD Ryzen™ Threadripper™ PRO Series Processors, the ASUS Pro WS WRX80E-SAGE SE WIFI, claimed to have "EATX(EEB) Form Factor", yet its dimensions were listed to be "12.2 inch x 13 inch ( 30.98 cm x 33.02 cm )". I have confirmed that it is oversized since I had to modify a Chenbro SR107+ chassis before it would fit - an excess of 0.2" was enough to require some fabrication. Generally, it's been a chore finding motherboards and chassis that comply with specifications, making me think that yes, indeed, and unfortunately, E-ATX does not seem to be a standard. [2]

Newbie here. I am the sole inventor of the ATX architecture (see patent reference). Everybody gets lucky from time to time and here "hit one out of the ballpark". I decided to edit the Wikipedia page after seeing the Chat GPT answer below...
>Who is the sole inventor of ATX
>The ATX (Advanced Technology Extended) form factor for computer motherboards was not invented by a single individual, but rather was developed by a team at Intel Corporation led by Robert O. "Bob" Simons in the mid-1990s. The team included engineers such as Steve Smith, Alain Le Guennec, and Jack Thornton, among others.
Frankly none of these people named were involved the ATX around the time that I patented the design. My search of Robert O. Simons shows that he worked at Microsoft, but I see no evidence the he every worked at Intel.
Just looking to factually correct the record. Suggestions welcome.
