Want to use one of the new external SSD drives (either 8tb Oyen Digital or 8 TB Prograde) as a media drive to replace aging G-Tech RAID. They both require 15w power. I cannot seem to find the power output spec. Is anyone using Thunderbolt 3-powered external SSD drives with the 2019 Mac Pro?
Mac Pro, macOS 13.6
Standard USB-3 ports (that are NOT shared with other devices) can provide up to 900 milliAmps at 5 volts, or 4.5 Watts.
you may be able to obtain more through USB power delivery protocol, but that is intended for charging connected devices.
[in my opinion] you should count on using an external power supply if you need 15 watts each.
Do the Thunderbolt 3 ports of Mac Pro 2019 output 15 watts of power to power external SSD drive?
