I assume its due to the ASMEDIA USB3 ports.
All USB3 ports on the rear of your mainboard seems to come from the ASMEDIA chip.
Check where the USB3 ports are located which come from the Intel Z97 Chipset.
You need to read your mainboard manual for this and eventually also open your case.

Depending on the results, whether its easy to use the USB3 ports from chipset or not you have 2 alternatives:
a) get this card, but I am not sure whether it impacts the amount of PCIe Lanes of your Graphics card if you place a card into the 2nd PCIe-x16 socket, as this is the only socket which offers 4 PCIe lanes for the card. You need to check this in the handbook. https://www.heise.de/preisvergleich/son … 79334.html
I am running it on my own very successfully with 2 UFX+ and 1 ADI-2 Pro connected.
Possible with this card as each of the 4 ports has a dedicated USB3 FL1100 chip behind it, so that each of the ports has the full power of USB3.
b) get this card, but I have no experience whether it has the same superb drivers. Best is to get both cards at once and look which fits best. https://www.heise.de/preisvergleich/son … 48037.html
Here the 4 Ports share one FL1100 USB3 controller.
