Paul Hynes is still in business and building new product. After a long wait I think I'm close to receiving a four rail version of his master power supply.
He mentioned that he is finalizing the design of a new model SR10 linear ATX power supply for motherboards requiring all the ATX rails including the additional 12V rail for the CPU and also ATX control compliance to allow it to work properly with ATX motherboards. Be forewarned, however, that this PS will likely price out higher than the PC server that it powers, and that Paul's lead times can be long.
