7-Port USB 3.0 PCIe Expansion Card

I have just ordered a Lynx Gaming PC. [ID 2350494].
This Motherboard has two PCIe slots, one for my GTX 1660 Graphics card and one spare. I intend adding a PCIe 7-Port USB 3.0 Adapter Card into that spare PCIe slot.

My Question is as follows:

I have a desire of splitting my use of the PC, into two monitors [one for driving sims] and [one for flight/TRAINZ/Sailing/golf sims].
Bear with me...
I tried this on my present Sim PC, without success [10-port USB HUB].

With all these USB ports on the back of my tower, [directly connected] I hope to be able to use almost all of them [13] for different controllers. My PC will have power to each monitor separately so that I can choose one monitor plus
Keyboard & Mouse.
G920 wheel & pedals.
G-shifter.
Tech Affliction Mega shifter. [looks like an Eton Fuller 18 shifter].
2x 32 button switch boxes [for all the dashboard switches/buttons/wipers etc.
Track-IR 5

Using a second Monitor and more USB ports.
Keyboard & Mouse [separate from the others].
CH Flight Yoke.
CH Pedals.
CH Combat Stick.
CH Throttle Quadrant.

Set up this way, I could use my FSX [or my] ATS/ETS2/Assetto Corsa/Project Cars 2. with the same PC but all the periferals separated.

My Xiberia T19 USB headphones and WiFi dongle are connected to the two USB ports on the front of the Chassis.

Tell me I can do this because I have two GT Omega Racing Wheel Stands [one for G920 etc] [one for CH Flight stuff], and I don't have to unplug and plug and move everything.

I'm hoping it's possible. Using a USB 10-port HUB it didn't work, but I hope that using a Motherboard [PCIe connected 7-Port Adapter it should work.

Cheers,
