Again.... without enough power the card will initialize but cant use it.
1. Without right BIOS settings
nvidia-smi reports initialization error or so
2. With the right BIOS settings but without 300 watt
nvidia-smi reports card doesnt have enough power
3. With the right BIOS settings and enough power
nvidia-smi reports card information
