The Mac Pro cannot supply 75w + 75w + 150w since it only has 6-pin power connections. Some people have cheated and used adapter cables e.g. to go from 6-pin to 8-pin but some people have then reported their Mac Pro shuts down to prevent an overload. Even if you avoid it shutting down there is a danger this excess load might literally melt the traces on the logic board supplying the power connection.

You can normally connect a 6-pin supply cable to an 8-pin socket, this will still only provide 75w but means you don't need an adapter. You can take two 6-pin cables and 'merge' them in to one 8-pin cable but this is going to deliver exactly the same amount of power as two 6-pin connections.

Thunderbolt combines PCI Express (PCIe) and DisplayPort (DP) into two serial signals,[9][10] and additionally provides DC power, all in one cable. Up to six peripherals may be supported by one connector through various topologies. Thunderbolt 1 and 2 use the same connector as Mini DisplayPort (MDP), whereas Thunderbolt 3 and 4 reuse the USB-C connector from USB.

Intel introduced Light Peak at the 2009 Intel Developer Forum (IDF), using a prototype Mac Pro logic board to run two 1080p video streams plus LAN and storage devices over a single 30-meter optical cable with modified USB ends.[19] The system was driven by a prototype PCI Express card, with two optical buses powering four ports.[20] Jason Ziller, head of Intel's Optical I/O Program Office showed the internal components of the technology under a microscope and the sending of data through an oscilloscope.[21] The technology was described as having an initial speed of 10 Gbit/s over plastic optical cables, and promising a final speed of 100 Gbit/s.[22] At the show, Intel said Light Peak-equipped systems would begin to appear in 2010, and posted a YouTube video showing Light Peak-connected HD cameras, laptops, docking stations, and HD monitors.[23]

In 2009, Intel officials said the company was "working on bundling the optical fiber with copper wire so Light Peak can be used to power devices plugged into the PC."[27] In 2010, Intel said the original intent was "to have one single connector technology" that would let "electrical USB 3.0 ... and piggyback on USB 3.0 or 4.0 DC power."[28] Light Peak aimed to make great strides in consumer-ready optical technology, by then having achieved "[connectors rated] for 7,000 insertions, which matches or exceeds other PC connections ... cables [that were tied] in multiple knots to make sure it didn't break and the loss is acceptable," and, "You can almost get two people pulling on it at once and it won't break the fibre." They predicted that "Light Peak cables will be no more expensive than HDMI."[29]

Intel and industry partners are still developing optical Thunderbolt hardware and cables.[31] The optical fiber cables would run "tens of meters" but would not supply power, at least not initially.[12][32][33] The version from Corning contains four 80/125 μm VSDN (Very Short Distance Network) fibers to transport an infrared signal up to 190 m (600 ft).[34] The conversion of electrical signal to optical is embedded into the cable itself, so the current MDP connector is forward compatible. Eventually, Intel hopes for a purely optical transceiver assembly embedded in the PC.[33]

In September 2013, glass company Corning Inc. released the first range of optical Thunderbolt cables available in the Western marketplace outside Japan, along with optical USB 3.0 cables, both under the brand name "Optical Cables".[18] Half the diameter of and 80% lighter than comparable copper Thunderbolt cables, they work with the 10 Gbit/s Thunderbolt protocol and the 20 Gbit/s Thunderbolt 2 protocol, and thus are able to work with all self-powered Thunderbolt devices (unlike copper cables, optical cables cannot provide power).[18] The cables extend the current 30 m (100 ft) maximum length offered by copper to a new maximum of 60 m (200 ft). This lets peripheral Thunderbolt devices be farther from their host device(s).

Intel's Thunderbolt 3 controller (codenamed Alpine Ridge, or the new Titan Ridge) halves power consumption, and simultaneously drives two external 4K displays at 60 Hz (or a single external 4K display at 120 Hz, or a 5K display at 60 Hz when using Apple's implementation for the late-2016 MacBook Pros) instead of just the single display previous controllers can drive. The new controller supports PCIe 3.0 and other protocols, including DisplayPort 1.2 (allowing for 4K resolutions at 60 Hz).[80] Thunderbolt 3 has up to 15 watts of power delivery on copper cables and no power delivery capability on optical cables. Using USB-C on copper cables, it can incorporate USB power delivery, allowing the ports to source or sink up to 100 watts of power. This eliminates the need for a separate power supply from some devices. Thunderbolt 3 allows backwards compatibility with the first two versions by the use of adapters or transitional cables.[81][82][83]

By default, PCIe provides power via motherboard PCIe slot, up to 75w via the port itself. The power requirements have increased for high-performance GPUs, going past PCIe's initial design. PCIe cards started coming with additional power ports and increased pins to carry more power to combat the power delivery problem. Generally, additional power is drawn directly from 12v taps off the power supply that the user can configure in PCs. The Mac Pro uses an uncommon passthrough where the PCIe power is delivered via pass-throughs on the motherboard rather than directly to the power supply and these use the mini-PCIe power cables format akin to it's older sibling, the classic Mac Pro. There are two power ports on the Mac Pros on the motherboard that can be tapped for additional power.

Apple's MPX standard is a modified PCIe GPU that has a secondary interface to provide Thunderbolt 3 video passthrough / Thunderbolt 3 ports and additional power delivery (removing the requirement for PCIe 6 / 8 pin power cables).

The first Intel-based tower Mac, the Mac Pro "Quad Core" 2.66 is powered by two 2.66 GHz dual core Intel Xeon 5150 processors with 4 MB of shared level 2 cache per processor, a 128-bit SSE3 vector engine, and 1.33 GHz "64-bit dual independent frontside buses." Also offered, via custom configuration, were two 2 GHz Dual Core Xeon 5130 processors, two 3 GHz Dual Core Xeon 5160 processors, or starting April 4, 2007, two 3 GHz Quad Core Xeon X5365 (Clovertown) processors.By default, it was configured with 1.0 GB of 667 MHz DDR2 ECC "fully-buffered" FB-DIMM memory (with a heatsink design that is a bit different from generic FB-DIMMs), a 250 GB (7200 RPM) 3 Gb/s Serial ATA hard drive, a double-layer 16X "SuperDrive", and a NVIDIA GeForce 7300 GT video card with 256 MB of GDDR2 SDRAM, one dual-link DVI port and one single-link DVI port.Expansion includes two external 5.25" "optical" bays (one occupied by default), four internal 3.5" "cable-free, direct attach" hard drive bays (three free by default), and four PCIe slots (three free with one graphics card installed). Ports include dual Gigabit Ethernet, five USB 2.0 ports, two Firewire "400" ports, two Firewire "800" ports, and optical digital audio in/out, among others. AirPort Extreme (802.11g/n), Bluetooth 2.0+EDR, and a modem are optional.Also see: What are the differences between the original Mac Pro configurations?

Problem I'm having with using an external SSD drive over thunderbolt is that I can't seem to find a solution for also using bootcamp if I go that route.so far, it seems, and I could be wrong, that if you use an external drive for the macos, you can t use boot camp. my problem goes even deeper because my internal SSD portion of the fusion drive seems to have failed and bootcamp seems to require it. So even though the macos was able to be installed on the HDD only, bootcamp wouldn't install because of a appleSSD. Sys driver error. So, for now the only solution I can find for a failed internal SSD portion of the fusion drive and to use bootcamp also, is to replace the internal pcie SSD. I've seen a YouTube video for doing this and it seems like you have to remove almost every component inside to get to it. 2b1af7f3a8
