Adding an SATA power connector to my NAS?

[Enquiries]

I am setting up a QNAP TVS-473e. I am following your excellent setup video series--thank you.
I have added a USB-C expansion card. It has an optional SATA power connector. The card installed fine and the ports are recognized by the 473e. I want to connect the optional power connection. Unfortunately, the 473e has no available power connectors of any kind that I can find. Do you have any suggestions for an adapter to add a SATA power connector to the harness?

NAS is not built as a PC. It is geared towards storage only. So power supply will likely be only big enough to handle a number of drive bays available. There will be no additional power sockets available on the motherboard. You could theoretically split the cables and create a connection yourself. But check if the power supply will be big enough to support attached drives. Also, your warranty will surely be voided.I hope this helps.
