It has been stated from my sources, that the ECS GF7050VT-M5 mobo, is the same as the ECS MCP73VT-PM, with a slight difference.
The difference being that the MCP73VT-PM mobo is based on the Micro-ATX form factor, and the GF7050VT-M5 is based on the ATX form factor.
[ Micro-ATX form factor size is 9.6 inches by 9.6 inches. 9.6 inches is approximately 9 and 9/16ths inches. It's also 244mm by 244mm.
ATX form factor is 12 inches by 9.6 inches. 305mm by 244mm ]

I'm also looking at an ECS MCP73VT-PM on Ebay, as well as the PDF motherboard manual for the ECS GF7050VT-M5.
Motherboard oriented so that the Processor is to the top, ram memory slots to the right, and the orange PCI Express x16 slot to the bottom, the SP/DIF header on the GF7050VT-M5 is located to the left of the PCI Express slot.
From the poor view on the Ebay link, the MCP73VT-PM also seems to have the SP/DIF header in the same location, but clocked differently.
The header is clocked perpendicular to the orange PCI Express x16 slot, while on the GF7050VT-M5 the SP/DIF header is parallel to the PCI Express x16 slot.
The header is 4 pins long, with 1 pin not installed.
Pin 1 is marked on the motherboard.
Pin 1 is SP/DIF Digital Output
Pin 2 is +5VA ( 5 Volt analog power)
Pin 4 is Ground
There is no Pin 3.
