I have no idea what the technical names are for the different connections. I can't find a place to plug in the ASUS DX PCI-e I need for an optical SPDIF inside a gateway slim SX 2850. There is no extra power connector that I can find. The connector supplied by ASUS is to a floppy. Is there a "Y" connector that can be used to the DVD or HD? There is also an extra four pin connection on the motherboard the same as the one that powers the CPU fan. Can this be used if I can find a cable. If so, what do I ask for?
