Headroom Notes
Unusually, ASRock states the Type-A current itself rather than leaving it to the specification: "Device exceeds USB 3.2 Type-A power rating of 5V@0.9A (4.5W) may trigger over-current protection." That is the same 900 mA the USB specification requires, but here it is the vendor's own number and it names the failure mode — over-current protection, i.e. the port cutting out rather than sagging. The USB4 Type-C ports are separately rated 5V@3A (15W).
Amplification Warning
The audio block repeats the Intel Taichi word for word — ALC4082, ESS SABRE9219 for the rear panel at 130 dB SNR, and "Direct Drive Technology on Front headphone port (Supports up to 600 Ohm headsets)". Same claim, same absence of an output level, on a board with a different chipset and a different socket.
Was im Datenblatt tatsächlich steht
Wörtlich von der Herstellerseite zitiert, mit dem Datum der Prüfung. Wir behaupten das Gedruckte, nicht die Absicht dahinter.
«Direct Drive Technology on Front headphone port (Supports up to 600 Ohm headsets)»
The identical sentence appears on the Z890 Taichi page for a board built around a different chipset. One impedance claim covering two products tells the reader that it describes the audio design family, not a measurement of either board.
