Looking to build a second rig since the first has been so good to me. I'm getting 6x gtx 1080 and they'll be +167 on core and +594 on memory but power limit set to 85%. I have a lepa p1700m for my first rig but they aren't available anymore.

 I take it a 1300 watt system won't cut it? So hard to find decent PSU in Europe....
6X 200W = 1200W, a 1300W should cut it but I would go with a 1500W just to be safe and ensure a longer lifespan of the PSU.

I've found one in the EU on Amazon but look at that price! https://www.amazon.es/Enermax-Platimax-1700W-ATX-Negro/dp/B01CIP5S8I/ref=sr_1_fkmr0_1?ie=UTF8&qid=1496839824&sr=8-1-fkmr0&keywords=psu+1700w

I'm sure secondary suppliers might have some but my US card will decline on anything but Amazon.

My GTX 1080 uses 180W at 70% TDP. You are probably looking at 200W per card. 1300W will be close with the mobo and fan power. If you do go with a 1300W, make sure it's platinum or better. I would use a 1500 W PSU  or a dual PSU setup if you want to save money.
