I have recently replaced my previous mouse with a Razer Mamba Chroma which also comes with a receiver/charging dock connected via USB to the PC to facilitate wireless mode. When I turn the PC off when not in use, USB power is also turned off to the charging dock. For me, this sort of defeats the purpose of being able to charge the mouse when not in use. I am aware that some if not most motherboards these days can pass power through selected USB ports when the PC is actually shutdown via the PSU’s +5V standby rail. It seems however, that my particular motherboard (MSI Z97M) does not seem to possess this feature, not that I could actually find searching through the manual and google anyway. I have unchecked all check boxes “Allow the computer to turn off this device to save power” within device manager and also searched through the BIOS in the hope that such a feature could be enabled, no luck either. If my motherboard doesn’t support this feature, would an externally powered USB hub actually do the trick or do most also only have power when a USB signal input is detected? Any help or advice would be appreciated, thanks in advance.

Here is your user manual and a screen shot that I think pertains to your issue! User manual >> https://www.manualslib.com/manual/831785/Msi-Z97m-G43.html

If that doesn't work then I think your MOBO doesn't support it. Good luck

2 things, have you installed the super charger software from the install disc? and turned it on? also the jusb1 header if it is connected to the front of your case usb ports you may have to plug your mouse in there for it to work. @DRDNA post too :) GL

I have the super charger software installed, as far as turning it on, I thought it was on by default once installed?? I'll check that too, thanks for the advice.

check your power profile for USB, make sure selective power standby is not enabled.

Disabled selective power standby as well, still no luck with any of the suggestions.

Speak to MSI support, and Razor, they are the makers of the products at this point.
