Review: No incluye cable de alimentación - Viene sin cable de alimentación, por lo que no puede usar velocidades USB 3.2. Compré esto para poder usar mi cámara como cámara web y transmitir en 4k. Sin alimentación externa, sólo permite una resolución de hasta 720p. Tampoco tengo idea de dónde comprar un cable de alimentación, ya que las instrucciones no son buenas.
Review: Oculus Quest 2's best friend - If you want to run a solid Oculus link with VR and be able to power it while you use it. You gotta get this card. I was trying to get away with not buying one and just charge my headset and plug it into a USB power jack and see how long it'll last. It ended up running out of battery in the middle of gaming and panicking to figure out how to rejoin the group was a challenge as I would have to plug my headset into the wall and needed to run Air link which is highly unreliable in my location with lots of interference. I bought this card after much research and solid reviews and it did exactly what i needed! Plugged my headset cable directly into it and it reads it perfectly, quickly, and keeps it powered with no more down time! Love my VR set up now.
