990FXA-GD80 v2 won't post after installing nvme

[GGman]

Hi, I used to run my 990FXA-GD80 v2 flashed to the latest bios 13.6 along with FX8350 + 32GB ram @ 1866mhz + 850w gold psu + a 1TB Gen3 nvme SSD via pci-e slot adapter generic (the motherboard doesn't have M.2 slots).
The PC ran very good for quite long time, until recently that I decided to upgrade the 1TB Gen3 nvme for a Gen4 nvme using the same NGFF pcie adapter. Now the system doesn't post, debug display show "FF" , "B2" , "19" , D6". Already tried with different components like CPU's, ram modules, GPU's, PSU's, even downgrading bios, with same issue over and over again.

The SSD Gen4 was brand new and after this failed installation, I tested it in another device.. turns out it broke. so I had to RMA. Several people said to me that the only difference between Gen3 and Gen4 drives are speed bus jump from pcie3.0 to pcie4.0, I already knew that the new drive would be downgraded to pcie3.0 speeds however I never imagined it could compromise itself as well as other hardware components! unfortunately I don't have any other AM3+ motherboards for testing cpu and ram separately but I already suspect the worst..

Any insights about what went wrong? why exactly? and how to fix it?

The Gen 3.0 Drive would be Ok but would be Working In Gen 2.0 Speeds as that Platform only has PCI-E 2.0 Lanes as its very Old. and a Gen 4.0 Drive Would Run at Gen 2.0 speed. Max Speed would be Around 1.7GB/s Tops on Either.

Main Difference is the Power Draw Difference Between a Gen 3.0 NVME drive and a Gen 4.0 Drive so it may be the 4.0 drive Was Drawing too much Power.

A Gen 3.0 Drive tend to Pull between 3W to 8W depending on its Load where a 4.0 Drive Pulls usually 5W to 10W under the same Loads. depending on what you have in your System it may be too Much as the Codes you Listed the one that is Troubling is D6 (No Console Output Devices are found) in Other Words it Can't see a GPU or A Screen Connected to the PC and is stopping as a Result.
