ASUS Xonar Essence ST - PCI Audio / Sound Card. Requires a 4 pin Molex power connector from your PC power supply to operate. This is a legacy PCI card - not PCIe In good, clean condition. Tested working ok on Windows 10 Pro using official drivers from the ASUS website - Beta version 8.1.8.1823 Please note: I was only able to test the RCA analog output from this card. The SPDIF & 1/4” jacks have not been tested for their functionality as I don’t have any SPDIF digital devices or 1/4” headphone plugs.
