Please, I come to this forum to find an answer to my research. I hope you can help me

My Celsius H710 has an eSata port that I would like to use to connect a SSD (Sata 3) and boot from it. Do someone know if this port is powered (Power eSata) or if I need an external power source to the disk ?
I'd like to avoid buying the wrong accessory.
Thanks for your attention, regards
