| 2012-09-27 18:50:15 | rev. 6 | CORRECT | Verified on an old Win2K box that matched exactly. | APPROVED |

| 2013-12-18 17:11:48 | rev. 6 | INCORRECT | I am looking at an AT power supply with the AUX connector as +5 volts (all 3 wires) not +3.3 volts. | APPROVED |
| 2014-08-10 05:21:27 | rev. 6 | CORRECT | Not an error but I can add that these two connectors are whar are used on a Lite-On PA-4022-6B Power Supply which came out of an old Packard Bell Desktop PC. It has several other 4 pin connectors but these two are the main motherboard connectors and the ones which must be connected for the power supply to operate as designed. | APPROVED |
| 2016-03-19 23:42:38 | rev. 6 | CORRECT | At least one P10 motherboard worked without proper supply (only P8/P9 were connected), but 3.3V PCI board didn't work on this motherboard due to obvious reasons. | APPROVED |

| 2019-11-27 04:22:03 | rev. 7 | ERROR FIXED | The P10 Aux you are showing [3x 3.3v] + [3x GND] is proprietary to some Dell socket 5, 7 and 8 motherboards. You show that and then talk about "extra wattage ... for 3.3 and 5 volts" but there is no +5v that connector. The standard 6-Pin ATX AUX has [1x +5v] + [2x 3.3v] and [3x GND]. If your image was of that one then your verbiage would make sense. . | APPROVED |
| 2021-12-01 18:41:11 | rev. 8 | CORRECT | The proprietary 3.3V connector is not only for Dell, but also IBM (especially Power Series) and Intel (e.g. Atlantis Socket 5 and similar Socket 7 mainboards). According to Intel documentation (e.g. Intel Advanced/AS mainboard), the pinout stays the same as shown in the document. The 3.3V has been used exclusively to power PCI slots - while on-board internal regulator usually makes 3.3V for chipset and CPU, it may be too weak for some PCI boards so in early mainboards it is not routed to slots. | APPROVED |

| 2011-03-23 14:41:07 | rev. 5 | [email protected] | По-видимому опечатка в описании P10; но достоверно не скажу. На плате у меня - 3 пина 3.3В.. |

Pinouts.ru > Pinout of AT motherboard power supply and layout of 12 pin 2x MOLEX 15-48-0106 connector and 6 pin 2x MOLEX 90331-0001 connector |
should be correct |
