ASUS Strix B550i rear audio uses USB Type-C for connectivity.
Hi, I built my PC using an ASUS Strix B550i and I found the Audio USB Type-C port interesting because it supports USB 2.0 even though it’s a Type-C connector. I have a few points to clarify: 1. Why USB 2.0 works with a Type-C port? It might seem odd at first, right? 2. What power does this port actually supply? The speaker I bought requires 10W from a USB-C port for "high gain" performance. 3. Can these ports deliver power when the PC is off versus when it’s running? Yes, and it works differently depending on whether the power supply is active or not. It’s fascinating how they manage power in that way.
It depends on the intended use. For audio, speed isn't crucial since lossless files already exceed 2Mbps and USB 2.0 offers more than USB 3.0. The ATX standard includes two power versions—normal and standby—while USB ports typically connect to the standby voltage, allowing operation even when powered off.
