I also have two of those 1500W supplies, and they are kick ass! Single/multi rail in one, load meter, nice quality cabling... I like using them to measure wattage draws on cards in real time, then I'll swap over to smaller PSUs when I feel everything is in safe running conditions. My only complaint is it's loud and you can hear the APFC clicks a lot when running 1200W of water cooled GPUs. Loudest thing in the build, by far
Are you running all 6 of those 280x's on one. I know it'll do it on 220, but I never really thought it would run all 6 at full throttle.
I agree, I had 4 280x running on the EVGA plus the CPU (Core i7 4930K) and the rest and it was hitting about 1400W... Maaaan that was loud! And yes it was the loudest thing in the setup. The fan does a good job to keep the PSU cool though. I have another 1600W PSU I got from CryptX made in Holland, the brand is Recom... It was about 150 a steal! So I had the other 2 280x running on that + some other Asic for BTC. I doubt you'll be able to run 6 280x cards on the EVGA if you want to leave 20% of the power to keep the PSU healthy. Still the EVGA is a great PSU would recommend to anyone who needs reliable power for their gaming RIG.
