MP 1,1-5,1 MP 5,1 installed PCI NVMe adaptor now no video display. HELP!

Hey folks,
MacPro 5,1
Mojave (latest)
Boot Rom 140.0.0.0.0
Saphire RX 580
Glotrends PCIe adapter card
1T WD Blue SN550 NVMe
2 X Samsung SA850 monitors via displayport

So I powered it down, unplugged it and shoved in the new NVMe into the top slot.

When I powered back up I got a chime but no display.

Reset PRAM, still no display

Removed NVMe adapter card, powered back up - still no display

Any ideas??

UPDATE
OK so I removed all of the HDs, 3 spinners and 2 SSDs and left the boot SSD in (DVDr connection). Booted, held breath and voila! I have a desktop!

Wonder if it's possible then that the Mac had booted to the choose start-up disk screen and I just couldn't see it?

Really regretting loosing the old video card....

I'll try adding in the NVMe card again and see what happens

Available in 250GB, 500GB, 1TB
PCIe 3.0 x4

I'll try installing an OS on it anyway before I send it back
