CORRECTYes, this is correct. Not much you can do to go wrong with the pinout! :)APPROVED
ERROR FIXEDMolex 44206-0007 is a header for the mother board, not for cable.
And viceversa, 39-01-2240 is a receptacle for wire-to-wire or wire-to-board applications.
CORRECTIm not voting that this is correct but simply that a note should be added that some ATX 2.X series power supplies use a connector where the extra 4 pins is a section that can slide off for ATX 1 use or be left on for ATX 2.X use.APPROVED
INCORRECThttp://pinouts.ru/connectors/wtx_24p.gif http://pinouts.ru/connectors/wtx_24p_cableconn.gif have been REVERSED.
Please correct these gifs shown http://pinouts.ru/Power/atx_v2_pinout.shtml.

Thanks again,

2008-10-26 01:55:38rev. 4CORRECTCorrect, although 5VSB can be anywhere from 500 mA and up on newer power supplies, to power peripherals when the computer is in sleep mode (my power supply is rated for 3A)APPROVED

2008-12-03 07:01:15rev. 4CORRECTThe wire colors, pin positions, and voltages via multimeter test match my HP Proliant ML110 G5 server's 365w power supply, Part# 445067-001 and Spare# 457884-001, after grounding the green wire to "soft switch" the power on.APPROVED

2012-01-02 10:42:33rev. 11ERROR FIXEDIf I'm reading this correctly, this indicates that the 5VSB line can deliver a maximum of 10mA. However the ATX 2.2 specs recommend that a power supply be able to deliver 2A.APPROVED

2012-05-21 13:17:37rev. 13CORRECTNo errors but the Molex connector needs to be highlighted more as it's not a standard pin methodology ie left, right, down a row, left, right, down a row...instead it's more like a chip where the pin numbering goes around clockwise/anti-clockwise. This can catch people out...like me :-) Other than that, this was a very useful page in reference to this 5V 30A burn in rig i'm building using a standard PC PSU.APPROVED
2012-05-22 21:38:57rev. 13CORRECTAPPROVED
2012-06-05 20:07:34rev. 13CORRECTATX V2.3 / EPS12V V2.92 both define that the PSU has to use remote sensing to compensate cable drops on the 3.3V line. Because of this there is an additional brown cable crimped together with the orange cable either to pin 13 (ATX) or pin 1 (EPS12V).APPROVED
