I am slowly building out my farm and have a couple rigs up that have had various configurations and I haven't been able to get my hands on PSU's bigger than 1000w.

I have 1 extra 1080 ti and one 1070 that I decided together could live off a 700w (I have a rig with 2 1080 ti's on one 700w and its been going for weeks no problems and good temps)

I'm also using a 2 year old gigabyte board which doesn't really like the pcie expansion adapters so I just tried one 1080 in the main slot to make sure everything was okay. I had previously tried one 380w PSU bridged to a 600w PSU and out of the blue, one of the PSU's just died.

I plug in a brand new EVGA 750w PSU, thinking finally learned my lesson about bootsy configs with old junk.
Mining begins for a few hours and I'm just happy this stupid motherboard is finally up and making coin.

I get a free moment and think, okay, let's hook up that 1070 and get this has rate over 1k sol/s. When I go to turn off the rig, i notice the PSU is hot and think that's odd (mind you there is one 1080 ti on at this point.)  

I hook up the 1070 position it all and everything, pick up the power switch and I'm staring at the CPU fan hesitate, spin a little, stop, spin again. stop. Smoke comes out of the hours old PSU. then I feel the wires and the 8 pin PCIe going to the 1070 is super hot.

To make things better, I can't remember where I got this - with the shortage of everything mining related I have been buying stuff that comes up on google shopping. It looks like a perfect EVGA unit too, but there is a big sticker that says made in China on it, never noticed that on my other EVGA units.  You guys are probably laughing for probably the 2nd time at this point.

This is a good opportunity to mention how much I like the 1060's and how versatile and less demanding they are.  

EDIT: oh good my other 700w power supply just died too. The one that I was saying supported the 1080 ti's "no problems and good temps." OKAY NO MORE  700's I GUESS
