One model available is the BU40N. There is an Amazon review/comment for this drive:

https://www.amazon.com/HLDS-BU40N-Internal-Blu-Ray-Optical/dp/B07BSF41VW

which states "I didn't realize that this player/burner is designed with a SATA III power port, which is SMALLER than a "regular" SATA port....I could order a cable adapter....RECOMMENDED ONLY if you have SATA III power connectors - otherwise you're gonna have to buy a cable."
