Hi @beanman56

Yes it is possible to run usb expansion in it but there’s a catch

Because the pcie bus can only only carry so much power if you plug to much into it (eg external hdd)

It can cause them to run slower as it’s hit a power limit

But along as you stay within its limits you will be fine

Hopefully this helps

Any questions please ask

Thanks:-)
