Hi cr0sh,
I went through the apps folks at Molex, Tyco, FCI, Samtec, Berg and others. No luck. I checked the ATX spec - no luck. I contacted 2 of the high end SMPS manufacturers who have products on the market: Quote "That information is not available to us."
Now, I don't know if there is a specific "trade group" for harmonizing the power connections for video cards to ATX power supplies (that's what the connector is FOR, correct?) but it would be even more reassuring to me to think that SOMEONE in the industry had a clue...
Really, I mean, think about it...where else can you get a 450W multiple output, regulatory approved, power supply for under 20 bucks? Seems like more products would be designed using them as a power source if the documentation was clear.
