Power supply for 4x470

[_ZET_]

1000W PSU is reasonable. It's always better to be sure you got additional energy limit.

Be aware you would use your rig in couple ways, not only for one exsisting coin.
Not sure how much energy will need new generation.
If you choose smaller one such as 650W you saved some money, otherwise you won't be flexible on market demand.
Be wise and always purchase well-knwon PSU with at least brozne/silver/gold mark.

I'm running 4x470 8GB with 650W PSU, of course bios modded and undervolted,
8GB RAM, AMD FX4300+ few 12cm fan attached.
Still have more than 100W in reserve.

i have been running a 650w GOLD with 4 x 470 4GB. Once i have it up and running i do underclock my cards to -100mv. Never had any issue and it doesnt seem to be heating up so it shows it is not stressing it. All ways make sure to feel your PSU if you are pushing it. The warmer it gets, the more you push it to the limit.

I've got one rig with a pair of R9 290s (which soak a bit more power than 4x 480s) running comfortably on a Seasonic X-850 (gold).

 I suspect a good 750 would be plenty for your rig, or even a very good 650 (like the Seasonic X650 or EVGA 650 G2).

 1000W for that rig would be a waste of overkill, unless you PLAN to upgrade it to "RX 490" cards when those get released.


 I DO make a point when I am building a new rig to put it on a wattmeter though - the dual R9 290 rig is eating about 650 watts all up at the wall mining ETH, which is WAY comfortable for a quality 850 watt supply.

 Under ZEC it was eating more like 550 watts.

 Plenty of room for future upgrades as the R9 290 is quite a bit more power hungry than ANYTHING current short of a Titan (The Titan X Pascal is TDP of 275 which would be CLOSE but not more, the older Maxwell-based Titan X was 350 or 375 which would STILL work but would be a bit marginal) or the possibility of a dual-core GPU like the HD 7990 or Fury Pro Duo.


 Realistically though, I tend to run rigs 'till they die, or they become uneconomical - and even the uneconomical stuff I keep around for other usage and sometimes something new comes along that they ARE economical on. As a general rule a card or MB has to DIE before I'll change a rig once it's built.

What I recommend to you is to use at least a gold 1000W PSU. I doesn't cost that more and it will enable you to do whatever you want. I personnaly use a 1000W PSU on my ADM rig, featuring 2x R9 380 and 2x RX 470.

1000W is more than enough for your rig.

Every 850W Gold or more will be sufficient.
