[SOLVED] Multiple gpu problem with Asrock B 450 K4

[Pochemumnehuevo]

Greetings. My system boots find when only gpu installed. Once I add the 2nd gpu (two identical rtx 2080 super) system wont post and kick me straight to bios settings, including no video signal from either gpu and 2nd gpu no matter which is connected would stop spinning all it's fans and kicks me to bios again. My psu is 1450w Gold. It's endless loop. I cleared SMOS multiple times, tested each gpu with difference power cables, changed PCI-e slots for each gpu. Again, 1 works, once 2nd connected same problem persist.Nothing helped.
Is this mobo even supports multiple Nvidia gpus?
Also in BIOS there is no such option as Chipset Advanced settings to enable IGPU multi monitor and CPU does come with radeon graphics
I want to use it for mining, I tested each card with each riser, as long as 1 card plugged in then its fine. Thx for any help , appreciate your time and forgive my grammar, still learning it as my ESL
1Chieftec Power smart PSU 1450w GOLD
2 CPU AMD Athlon 200GE AM4
3 DDR4 Gskill 2666mhz 8GB
4 Asrock b450 Gaming K4

To make this discussion as helpful as it can be I want to inform everyone that I checked all cables very carefully and plugged all necessary power cables to correct connectors, 2 8pin to gpus etc

I think your problem is the 200GE CPU. It has less than "normal" PCIe lanes -- https://en.wikichip.org/wiki/amd/athlon/200ge
It only has 10 PCIe lanes and only 4 are available to the PCIe slots.

Are you trying to run these in SLI if so not with that board the2nd slot is just X4. Besides as stated above.

Also in case your using a NVME boot drive.

*Supports NVMe SSD as boot disks
If M2_1 is occupied, PCIE4 will be disabled
