I have a question. Is it enough to power up 1050ti with a single FDD(4-pin) or SATA Power connected to the m.2 power slot?

I have been searching this for hours, b/c I ordered same M.2 m key to pcie x4..

The only thing that I'm concerned about is will it bear through 200W Dc-DC power adapter.:(I noticed the maximum amps that can go through sata cable is 4.5 A and with some extra juice from the board's M.2 M key slot.

If not enough, I am willing to set power limits to my 1050ti for stable 1050ti gaming

See this testing:

In the test above, 65W - 75W will need to be supplied.
That's definitely beyond what that little 4-pin Molex connector can supply.

If your Graphics card has its own 4-pin or 6-pin power connector on that GPU card itself (typically on its right-hand side edge), direct-feeding 12V power that way would be a much better bet.

The port really only needs to provide the data signal.
The power you can provide from a PCIE riser.
Most risers will provide between 35-75Watts without many issues.
Above 75Watts, you'll need a graphics card with a 6pin connector on the top to divide the power.
