Motherboard GA-890GPA-UD3H low power in the back USBs

[Sepharite]

I've been using GA-890GPA-UD3H for about a year, and whenever I plug in my mouse in the back, it starts to lose wireless connectivity despite having no obstructions.

Same with my USB wireless adapter. I would get max of 600kB/s, while the front USB would give me full power of 2mB/s.

Is there something in the bios that needs to be configured?

I'm using only a 500W PSU. Is there a way to tell if the PSU is being pushed to its limit? Could that be a reason?

I doubt it is the PSU. First, check the power management settings of the usb wireless adapter(power saving features cause problems). Check for driver updates for the chipset, and make sure you are not using the USB 3.0 port. Lastly, check for BIOS updates.
