Question GeForce GTX 1660super on Pegatron 2AB5 motherboard?

[wyrwir]

My new GeForce GTX 1660 super does not work with Pegatron 2AB5 motherboard. After displaying BiOS screen, graphic card stops working and system does not boot.
All the data I could find show the card should be compatible. Pls give me a clue

There is a known issue with a lot of these older prebuilt motherboards of this era.

For this one, there's a custom BIOS floating around for this motherboard that people have used. However, any kind of BIOS update, especially to a custom-made one, carries significant risks that you need to consider carefully.

I also cannot specifically endorse any use of any GPU without knowing the exact PSU in question.

It did not help.
I am not sure if BIOS modification worked at all since I did not see "BIOS settings have been reset to deafault" message after rebooting as it was described in readme.txt

PSU is HP model DPS-600WB A
