i have an Asus Z170-A ATX LGA1151 Motherboard and it only has 4 usb ports on it and then i have two on my case so a total of six, all four usb's in the back are being taken by keyboard(blackwidow chroma 2x) mouse (deathadder 1x) and mousepad(firefly 1x), leaving two on my case for other things, i have an amazon usb port thats powered but i cannot connect most things to it without it needed more power(usb powered mixer for my xlr mic). I kno u can buy pcie cards that have usb ports on it, so im just wondering what the best one would be for my situation? if u need more info on what im connecting just let me kno, i would like a card with four on it if it could power a mixer and webcam at the same time, even two pcie cards would be fine
