A two-fer.
I doubt that the 1050 ti uses the full 75 watts when mining Cryptonight - the 750 ti certainly didn't, it used more like 30-40 watts out of IT'S 75 watt TDP.
Yes, good point. Unfortunately, the 1050 Ti doesn't seem to report power use figures like its bigger brethren (or, at least, my Zotac mini doesn't), so the only way to tell is by looking at the difference in wattage of the whole system when mining vs. not mining, and that tends to bounce around by 20W or so anyway.
Well, no thanks to you slackers I can now answer my own question from earlier - the board is, indeed, a diminutive 195mm x 374mm. Surprisingly small, really. The PCIe slots are spaced 50mm apart so cooling of big cards with "impingement cooling"* might be challenged, if not marginal; cards with blowers should fare better.
That is narrower than the Aoris 1080 ti - forget trying to use a "2.5" or "3 slot" card in that motherboard AT ALL except in the one "end" slot, or on an "every other slot" basis.
It's very close to, or is the same, as standard "every other slot" spacing on common motherboards - even standard 2-slot wide blower cards are going to be airflow challenged.
Yet another good point - I just checked the spacing of another mobo that has 2 GTX 1060 in it - and which need an external fan blowing on them to keep temps under 65C - and the spacing is 6cm... Well, one can always use a bigger fan, I suppose.
