Unless you read the design guide update carefully that method doesnt work because it doesnt refer to any sense wires besides the 3.3v sense wire (brown or light orange).
Did you read the last paragraph in the [link=http://web2.murraystate.edu/andy.batts/ps/DESIGN_GUIDE.HTM]design guide update[/link]? I suppose the assumption was that you would read the section on remote sensing carefully -- it does reference sensing on the +5v and +12v rail. I have also seen one supply with a sense wire on ground.
I've converted around 80 or so supplies and run latch and voltage level tests on well over 200. There is a lot of variation across models - some supplies will latch and hold without a preload; some will not. A few will run without reconnecting the sense wires; the majority will not. Stability under load varies considerably -- Antec and Sparkle have performed well. To cover all the bases in the conversion process places some burden on the reader to be equally diligent.
If there is mis-information in the conversion, I would appreciate knowing.

I meant that the sense wires are not mentioned in the general conversion, just in the design update.
In the few psus that I have converted I have never seen a sense wire on ground, it's interesting that it's there but I see no need for it, Ill edit my write-up (again) and add that. As far as I know all ATX power supplies require a load to function while the older AT power supplies do not, are you sure you didn't test AT ones? Please let me know so I can add that. Thanks for the info hat some psus will work without connecting the sense wires too, Ill add that in there too.
