Sidenote are sound cards making a comeback?
Might be an audiophile thing? I’ve been debating getting one myself simply because the onboard one is really limited in its abilities
I would not buy PCI audio stuff. Lots of power goes through the motherboard, which makes these prone to RF interference, especially if you have a rig that has high power draw.
Best to buy a external USB dac/amp. Either make sure that your mobo has a separate USB hub from the main ones (which some mobos might label them DAC), or a USB cable that isn't rated for high voltage.
USB 5V power can be equally noisy, even from a powered hub, so that argument doesn't make any sense. PCIe has a high current 12V rail available that has much more margin than USB for filtering with an LDO and run your signal chain well above the noise floor of the components.
Besides, Asus Xonar as in the picture can take 12V from a drive connector to bypass the motherboard PCIe 12V "just in case".
