"full-size" -- 10W vs 25W
https://en.wikipedia.org/wiki/PCI_Express#Power

the 1st bulleted item says x1 cards are limited to 10W. the 3rd bulleted item says "full-size" x1 cards may make a grab for 25W.

but what is "full-size"? it is nowhere defined in this article. that is not an official term.

"PCI Express® Card Electromechanical Specification Revision 2.0" section "4.2. Power Consumption" explains the 10W limitation exists for HALF-LENGTH x1 cards; those which are less than 7 inches deep. the reason is for heat dissipation via simple convection.

snippet:

"PCI Express® Card Electromechanical Specification Revision 3.0" section "4.2. Power Consumption" maintains the ordinary half-length x1 card's 10W limit, but increases other cards' limits to 75W after configuration. snippet: As can be seen, the Revision 3.0 info (circa 2013) substantially supersedes the content in this Wikipedia article https://en.wikipedia.org/wiki/PCI_Express#Power which is at this point woefully obsolete and inaccurate.

PCI Express Mini -Pin layout, and voltages
PCI Express Mini Card Pin layout should be included. And, PCI Express Mini voltages are stated 1,5 and 3,3 V, whereas the msata variation is specified 5 V. Could somebody resolve this? 87.185.213.192 (talk) 16:41, 25 March 2024 (UTC)

Cabling
The 'cabling' section stops at OCuLink-2; it looks like PCI-SIG put out standards in early 2024 for PCIe 5.0 (and 6.0) cabling: https://www.anandtech.com/show/21379/pcisig-completes-copprlink-cabling-standard-pcie-50-60-get-wired. This round is called 'CopprLink', not 'OCuLink' -- no more allusion to a dream of eventually including optical cabling. 135.180.194.206 (talk) 06:36, 19 May 2024 (UTC)

Should add: the linked article notes that there is a working group established last year to create an optical cabling standard--so they haven't dropped the dream so much as separated it from the standard they're calling CopprLink.
