Pop a Samsung 960 inside that guy and you'd have a
Flash drive to die for!

Would be a risky buy. Very few NVMe SSDs (actually none come
to my mind) that can operate below the 4.5W limit of USB 3.1 Gen 2.
Only TB3 ports are guaranteed to supply higher power (or the
Gen 2 port must support higher PD profile)
"
Maybe a USB C connector on the host system could do that ?
Where the risk might come in, would be when cobbling
together a regular USB3 connector to the USB C.
Since the NVMe runs at half speed, that may have
a small effect on power consumption.

Yikes!
https://en.wikipedia.org/wiki/USB-C#USB_Power_Delivery
VBUS and GND provide 5 V up to 900 mA, in accordance with
the USB 3.1 specification. A specific USB-C mode may
also be entered, where 5 V up to 3 A is provided
For the Samsung 960:

AVERAGE POWER CONSUMPTION
(System Level)3)
Typ. 5.1 Watts (512 GB)
Typ. 5.3 Watts (1024 GB)
Typ. 5.8 Watts (2048 GB)
5.8 W / 5 Volts = 1.16 amps.
So, a C connector would be required.
Sure hope I don't have to clone one of these pretty soon!

Just checked the specs on the
Siig JU-P20A12-S1, USB 3.1 2-Port PCIe Host Adapter
Power output:
Type-C: Up to 3A
Type-A: Up to 900mA
And it comes with a Molex connect for hooking directly into
power supply
No Windows 7 drivers though.
Oh and I also noticed on the Wikipedia article I linked to
about that the C cable also has to be rated for the
higher current.
But that's the whole "C thing". Playing the
roulette wheel when getting a cable. And discovering
the hard way, it isn't quite right.
That's why we have addin USB3 type cards, so if
you ruin one, it might not cost you a motherboard.
I don't have any USB-C stuff here at all. No adapter
cables. Nothing. All I have is Type A USB3 Rev.1 for
the most part. My Rev.2 card is the first Rev.2 item,
and it has Type A connectors.
(USB.org knows how to run an operation)
