Title: Minim PSU for GTX 1080 rig? Post by: thesavoyard on June 07, 2017, 12:35:29 PM 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.... Title: Re: Minim PSU for GTX 1080 rig? Post by: Vann on June 07, 2017, 12:43:23 PM 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.

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 (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.
