Question MSI B650M Project Zero USB-C port power output

[davidbenpark]

This stuff is making my head spin.

The rear IO on the MSI B650M Project Zero has 1 x USB 3.2 Gen2x2 Type-C. I want to know how many watts this port outputs, because I want to know if I can use it to power a USB hub that will power a Creative Sound Blaster GS3 speaker, a Presonus Audiobox 26c, a Logitec Brio 500 webcam and a mouse, keyboard and Xbox controller dongle. The MSI website and documents don't explicitly state the number.

The plan is to have my PC a bit further away, and plug all these into a hub, but the power draw may be too high.

The soundbar doesn't need data, just power from a PD port as it's just acting as a speaker from the soundcard aux port.

Help! Thanks in advance.

How far are we talking about here?

You might want to look at powered hubs for your overall project/connectivity. Something like these or this.

Conversely, I'd run each device off a standalone USB port off the motherboard's rear end as my history with hubs has mostly been misses.

Thanks for the suggestions.

I have a really long desk and the pc is about 2.2m away from the peripherals.

I could maybe go with a hybrid approach - extension cable for the soundbar and then try a hub for the webcam, soundcard, mouse, keyboard and Xbox controller dongle (forgot to mention that).

If you're wondering why I don't just use the IO ports on the mobo, it's a Thermaltake Tower 300 case where the IO is behind a lid and case fans so it's hard to get to quickly. It's also resulting in some dodgy interference on Bluetooth devices like the keyboard and mouse.

I could maybe try a usb Bluetooth dongle on an extension cable for the mouse and keyboard, just leaving 3 other peripherals for the hub.

It might be 1.5A @ 5V (7.5W) (or possibly less). It could be 3A @ 5V (15W). If the design conforms to USB PD 3.0 you vague chance you might get 5A @ 20V (100W). Only way to be certain is to ask the manufacturer of your system, if you can't find the info listed elsewhere.

An excellent idea. I'm not a huge fan of unpowered USB hubs. I'm much happier if the hub has a separate DC power input. I've used Inatek USB3 hubs with auxiliary DC power inputs and they cope well. Low power USB memory sticks are usually OK, but some USB devices need more power.
