Topic: Power supply for 4x470 (Read 2599 times)
Every 850W Gold or more will be sufficient.
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.

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.

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'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.

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.

believe or not that's not really much power being used i was worried more about it dropping off to zero what that was doing pool side or how good that is or what dmg if any it might do, my power is free to some extent as well .I mean i help pay it because i want to i don't have to, it's only fair i use it so i should help some.
using nheqminer 4.0 something ? .I tried that for a while even got more hash out of it for maybe a hour then for no reason i saw either the CPU or the GPU would stop hashing for a while then pick back i wasn't over heating no errors i could fine any place it just stopped from time to time after that hour using nheqminer 4.b something .
Yeah, there is 0.4a nheqminer. About 10 sol/s, but I don't care about electricity (it's free) so I don't mind CPU mining, because it's better than nothing, idling. One rig's CPU is working 24/7 for like a week or two, but another one stops, shows 0 sol/s from time to time as well, strange and buggy.
Good luck that claymore miner never stops, and is super reliable.
he right i was doing about the same with a 850 watt gold PSU i was hitting 562 watts at the wall with three 470 and one 480 but mine are modded to use less power and hash more i can probable get more out of them at a cost by max over clocking and hope i don't make them to unstable , il play it safe i found my sweet spot.
Strange. How come then I have 3x470 and 600W PSU wasn't enough for them? Maybe because I was also mining on CPU of this PC? Maybe should I try without loading up CPU miner?..
by using the CPU using to mine using software ?. . what software miners are you using ? .
try this if your using the nice hash miner that's what it sounds like your using ? .

remember if there not tweak right thy can use more power at stock settings and hash slower . and 80 Bronze is rated lower then a 80 + gold PSU .
I'm using Claymore as GPU miner, and nheqminer for CPU.
I will check, I have ASUS Strix 4 GB RX 470, will check if there is proper BIOS for that.. Thanks
I'm a bit afraid that I can damage the card/cards... But I guess it should be worth it.

or
689 sol using 562 watts at the wall with only one 480 so if i had two ID be close mine are all 4gb cards so it would be close.

Hi @stoleyourburger,
Do you have any ideas/suggestions on what PSU should be used with 4x470? Should I not try to save money and ... for 4x470?
... yes of course !
Take EVGA-QG750-v2(?) ! gold !
... is running fine wt my i3-6100 + 2 x RX480/8 + 2 x RX470/4
~ 750 sol/ @ 700W from Wall

PanneKopp yea the best way is modded the bios to use less power and produce more speed that what's so nice about these cards now that use 14 NM chips . and they are just getting started ..
you can use afterburner or the WattTool but nothing works better so far then letting the card do it self but modding the bios and doing little tweaks with those tools .

Sorry if I ask a lot, but do you have a proper guide for RX 470 to undervolt (BIOS way)? I'd greatly appreciate that. Thanks!

I appreciate that! Didn't test yet, but will.
Thanks!

I have 5 x 480 undervolted rig with 1000W PSU, and with zec it takes 520W from the wall. So I thing 600 - 750W is enough for 4 x 470.
That is right. If you undervolt, 600W is more than enough.
So I guess in case of undervolting, the Sol/s is decreasing, right?
no not really i thought the same thing will lower heat and use less power but less sol maybe not if done right.undervolting doesn't all ways mean it will lower the speeds .
Oh thanks, so how do you undervolt exactly? Modding BIOS, or using MSI Afterburner? Or any other software?
Thanks!
