I am building a new system for my daughter based on the ECS K7S5A MB. On previous motherboards I have seen a 3 pin connector for connecting the power LED which properly mates to a 3-pin connector on the end of the power LED cable. However the instructions in the user's guide are somewhat compromised and I was able to deduce that connector pins 2 and 4 are reserved for this purpose. This is confirmed by the diagram ECS supplies on their web site. So I am left trying to figure out how to connect a 3-pin header to a 2 pin connector. Did ECS change the standard and not tell anyone? Does any other mfg. do this? Are their multiple standards? Yeccchhhh!
