PCIe sound cards

PCIe

— the PCI Express (PCIe) interface is a successor to PCI and is also used for internal peripherals, including sound cards. It is available on almost all modern motherboards, so when purchasing such a sound card, the issue might not be the availability of the interface itself, but the availability of free PCIe slots. However, this is primarily relevant for systems in a compact form factor, such as micro-ATX.
