Apartment rewired today, still stuck on 20A.
Landlord bought me a bottle of cheap whiskey for my troubles, though he also helped himself to a few shots of my tequila

Got my Watt meter, going to do some testing. Also installed a 1080 on a Rosewill 1x riser.
Mobo recognizes the card, but not showing up in Windows . . . going to try driver reinstallation.
Rig pulls about 120W mostly idle, incidentally

That did it! Ordering some Thai while it benches for nicehash. Then, onto power testing.
Goal will probably be to maximize power use by cards, conditional on total power use <= M
M tbd, will mostly be a function of observed refrigerator and monitor draw.

Early findings:
(i) i7-5820k @ 3.8GHz draws only an extra 30W when full-tilt running CryptoNight (350H/s), that's awesome
(ii) running a 1080TI FTW3 @ 100% pulls an extra 269W, about spec. Every 10% reduction in power target reduces draw by about 30W. Will test performace drop.

Fascinating.
1080TIs seem to see 1:1 gains in hash rates as power increases until about 80% TDP, when the return drops off dramatically
1080s drop off dramatically at . . . 65% TDP? Less?
Interesting implications for power use optimization anyway

Ok. Final tally, for 4x1080TI @ 80%, 3 x 1080 @ 70%, 35 CPU cores >= 3GHz is . . .
1779 Watts
Comfortably under my 1920W continuous limit although a bit dull numerologically
main remaining concern is the fridge. rated 6.5A full-load, which would be (eep) 780W, insta-game over

GOTCHA
160W, pathetic. Can't believe I was worried about that damn food hole
Modem (<7W) + router (<8W) basically negligible, as is Penny's Litter Robot (<4W rotating).
Monitor + speakers + usb dock are 70W together tho, gotta watch that

Okay, off to catch up @ work but I think I'm set. Last task: replace one more 1080 on top of my workstation after a guy comes in to finish fixing the ceiling tomorrow
Overall have say, the fire what burned through my ceiling was a small, basically-insignificant bump in the road

I wish the government would just fucking rob me directly instead of forcing me to keep meticulous records of the size and associated fees and contemporaneous USD value of BTC for

wait can't you just dump that from your client and throw it into excel

slightly more complicated, they don't record contemporary BTC price which I need for computing subsequent capital gains 🙄

I believe there's services that allow you to export this as csv, at least there were in 2014 when I was doing some analysis on the leaked gox data
