PC won't detect SSD

Bit of a weird one here.

I recently upgraded my setup to a new i9-9900k, Geforce, RTX 2080 Ti, and added a new PCIe card to gain 4 additional usb 3.0 ports.

After the upgrade I noticed one of my SSD's no longer displays in windows, disk management, nor in Bios. I've checked the cables etc. and all is correctly connected. I can't imagine it's a PSU issue as I have a brand new 1200W Platinum rated PSU. Anyone seen this before?

Things I've tried/additional info:

I am using a Gigabtye Aorus Z370 Gaming 7 mobo with the latest Bios revision.
Bios set to use AHCI.
I have switched out the SATA cable with another known working cable.
I have switched the SATA port the SSD was plugged into.

I have successfully plugged in a brand new SSD which was recognized. This piqued my interest though: The new SSD was at first not recognized and was displaying the same symptoms as the problem SSD until I plugged it into SATA 0 on the mobo. I have since tried plugging the problem SSD into all the other available SATA ports on the mobo without success.

Anyone seen anything like this before? All the other drives came up fine after switching out the CPU and GPU.

I once had an m.2 SSD randomly die on me after taking it out. It could be that your motherboard is just confused too. Looking forward to your answer.

Ok, so I plugged the SSD in question into another pc I have and the drive came up right away. So it's definitely a working SSD. I'm just about out of ideas. What do you think next steps would be? Clear CMOS?

Update* clearing the CMOS didn't help either. Still can't see the drive.

I'll try this later tonight and post back with the results.

*Update: You called it, it was the dastardly PCI card. The SSD showed up immediately after removing it.

So weird, I wouldn't think a PCI card with extra USB 3.0 ports would cause an SSD to disappear.
