It has 12V and 5V but no 3.3V. I don’t think there’s any way to know Watts except to load the system up until it stops. Hopefully it powers off before something melts. At least you shouldn’t exceed the amps allowed by the individual wires connected to the 10 pin connector.
Can you link the correct board-header option?
I didn't say the connectors were proprietary. You can buy the connectors that will fit and make your own cable. I am saying that the connections to the connector (pin out or wiring) is proprietary. The only part that is not proprietary is the PCIe 6 pin or 8 pin (GPU) end of the cable.
OWC has a much clearer picture of the PEX8796 in its 2019 Mac Pro teardown.
I’m not sure you’ve shown non-proprietary-ness yet.
First you linked a cable for a Power Mac or Mac Pro which is Apple specific. Maybe you want the 2019 Mac Pro to have connectors like the classic Mac Pro? But maybe the classic Mac Pro’s connectors were not enough for 8 pin PCIe power (150W each). Possibly the onboard 6 pin connector of the 2019 Mac Pro is the same as the classic Mac Pro.
Then you linked a PCIe extension cable which is only for extending PCIe power cables. Maybe you want the 2019 Mac Pro to have male PCIe power connectors on the motherboard instead of the female connectors.
Yes, it’s annoying that the Belkin package comes with cables you don’t need. But it’s like any modular PSU you might buy for a PC build.
What does a non-proprietary 6 pin or 8 pin PCIe power connector look like? As for as I know, only the GPU end of the cable is non-proprietary. PSU manufacturers use different pinouts for the PSU end of the cable even if the connectors are the same. Even PSUs from the same manufacturer can have different pin outs for the PCIe power cables.
If there are Thunderbolt 3 header connections, then they must be in the I/O card slot and the MPX module slot.
Step 14 has a picture of the PCB for the top power button and top Thunderbolt ports. The WiFi/Bluetooth is probably under the flat flexible cable.
The pictures show the four 4 lane DisplayPort 1.4 connections are at the end of the MPX slot away from the MPX power pin. So the unused pins near the MPX power pin are probably for the two 4 lane PCIe connections for the two Titan Ridge Thunderbolt controllers that the Radeon Pro 580X doesn’t have (and probably four USB 2.0 connections if Titan Ridge doesn’t support USB 2.0 itself).
Yes, the driver for the USB 2.0 port on my Titan Ridge dock is AppleUSBXHCITR. TR = Titan Ridge.
The Titan Ridge is different than Alpine Ridge because it has a USB output that is separate from the two Thunderbolt outputs. The downstream Thunderbolt port can be used for USB (port 1 for USB 2.0, port 3 for USB 3.x), DisplayPort, or Thunderbolt. The USB output of the Titan Ridge is just for USB (port 2 for USB 2.0 and port 4 for USB 3.x). I have tested a USB 2.0 mouse and a USB 3.x flash drive.
The Blackmagic eGPU is similar to my dock but it uses a JHL7540 so maybe all Titan Ridge chips have the separate USB output. So what makes the JHL7440 special is that it can accept USB-C with DisplayPort alt mode as input through a Thunderbolt port. And so there don’t appear to be any shenanigans required for USB on Titan Ridge in peripheral mode.
As far as I know, You can only use both USB ports of Alpine Ridge when it is in host mode which has both Thunderbolt ports as downstream.
