Dell G15 5511 Soundcard Power Output

Hello, I have recently bought new headphones for myself and was trying to look in advance if my laptop would be sufficiently powerful enough to support their ohms. I have been able to find the soundcard ( LS-K66DP 07C6KC ), though for the life of me cannot find any information on how much power it can output. Is that the right place to look, or does the motherboard power the headphones instead?

Voltage, power, current, anything's useful for me. If you have a high impedance headphones, it would be helpful too if you have information about how well the G15 can run it compared to a DAC/AMP. Thanks in advance.
