Whenever possible I just use one PSU - usually a server one like the ood -2000BB w/ a breakout. It's by far the cheapest option, and will give you great quality power. With 13 1070's, you'll be at the limit of a DPS-2000BB, so get the DPS-2500BB, which has 2320W. On my 13 card rig I'm actually running 2x 1650w PSU's.

Good luck with the build - it's a great motherboard, and a beast of a machine.

Good point but I prefer to avoid server-grade PSU. They're cheap but also noisiest compared to desktop-oriented ones. Moreover I'll need additional cables and usually they're less efficient. The DPS-2000BB for example is 80 Plus Silver (85%) against 80 Plus Titanium (90%+). I know that it costs 4 times more but money is not a problem.

the config is OK, except one thing - GPUs - is it relly wise to buy NV gtx 1070 which cost about $400-420 and push 30 Mh/s on ETH instead of RX570 8GB/ RX 580 8GB card, which can push ( after tuning) same 30+ Mh/s but costs about $290-320 - that is actually 35% difference. this is huge man.

first of all you don't mine ETH with nvidia, so you need amd here, second you are okish wit the 1500 watt for 12 gpu, if you underpower them a bit, they do 120watt x 12 it's there...

I admit that I decided to go for gtx 1070 just because AMD scares me a bit. Usually AMD cards are cheaper which is a plus but they use more power, have slower support for drivers (DAG issue has been fixed in... months? can't remember) and need more tuning. On the other hand I see people getting 30+Mh/s on the gtx 1070 farming ETH and consuming 105 watt with just few restarts. Isn't it impressive?

Let me make it clear. Money is not a problem. I'm not trying to save a few bucks. All I want is a mining rig with the best possible hasrate / power consumption ratio. As far as I know an RX 580 can't give me 30 Mhs @ 105 watt mining ETH. That said, if we don't consider the price of these cards, can we say that the gtx 1070 has a better watt-per-hash ratio than the RX 580?
