[Help] Need help with finishing two x5 1080s rigs

[Saikoo]

Hey Guys,

My 1080s will arrive in 2 weeks and i'm looking for a PSU and Riser options. Already have racks, cpus, ssds, ram sticks and these two GA-H270-HD3 mobos for x5 1080s each.

I'm thinking of getting EVGA 1200W PLATINUM for each rig. Will 1200W be enough if I underpower the cards? Here is PSU's power slots picture: https://images-na.ssl-images-amazon.com/images/I/71iR2DnioDL._SL1200_.jpg

But my main concern is Risers. What kind do I use that are the safest? I heard that SATA ones catch on fire. What are my options with this setup? Will I need to buy any any extra adapters to power risers from PSU? Will my PSU's power slots be enough for gpus and risers? Please help

My 6 card EVGA 1080 FTW rig pulls around 1000 watts & 9 amps at the wall. That’s @ 70TDP. A 5 card a rig I think a 1200 watt power supply would be fine.

I'm getting EVGA 1080 Gaming ones, 1200W should be just right then. Any idea about risers?

These are what I used in both of my rigs, I did not have any defects. Have heard that it’s a common problem though. https://www.amazon.com/gp/aw/d/B074PS39BK/ref=ya_aw_od_pi?ie=UTF8&psc=1
Have 6 more for the rig I’m building this weekend and just ordered more last night.
