The PSU should be a EVGA or CORSAIR 1200 watt , fully modular and Platinum rated like the Hx1200 from Corsair, this PSU can keep up 5 cards even if they are running near 200 watt but that is not the case because when you are mining Ethereum they are consuming 135 watt each from GPU-Z or MSI afterburner app.

I would advise you to buy 6x 1060 GB 3GB for 1200 USD which would be a better choice, the consumption would be much lower than with RX 580 and you can mine Zcash to get approximately the same amount as for 5x RX 580. Make sure to buy a good motherboard for mining, like ASROCK H81 PRO BTC which supports 6 cards easily.

The ONLY Corsair line I will even look at is the AX - the rest all use CHEAP JUNK "fancy name" sleeve bearing fans that do not last at high loads.
The AX line happens to be basically the old Seasonic SS-series Platinum rated power supplies with some very minor changes (same platform as the Seasonic X-series Gold supplies).

EVGA G2/P2/T2 line is good, but I don't know if they still make them.
Their newer G3/P3/T3 line has those junk "fancy name" sleeve bearing fans, I won't even LOOK at the things.
EVGA GQ line uses junk "fancy name" sleeve bearing fans.

The H81 Pro works well, but it's Socket 1150 which is getting hard to find decent low-cost CPUs for.
I have no idea what they changed on the "rev 2" of that board vs the original, but since the original is long out of production it doesn't matter much any more if you don't already HAVE the original.
I think they make a H110-based update to that board that is socket 1151 and otherwise pretty much the same.

The GTX 1080 isn't a real good mining choice - it's not BAD, but it gets beat on efficiency by the 1070ti on NVidia-friendly coins and the 1070 beats it hands down on ETH - not that the 1070 should be mining ETH anyway, it makes more on other stuff.
1080 isn't a BAD choice - just not optimal on hash/$ or hash/watt though close vs the other NVidia options.

AMD high-end Polaris cards do well on Ethash coins (ETH/ETC/related), fair on Cryoptonight (Monero), and tend to not be all that good on much of anything else (probably some small niche coins they do well I don't know about though) though not BAD, just not optimal....
