no not really i thought the same thing it 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 . it can and does make the card more effective in how they use power and produce heat .

So I guess in case of undervolting, the Sol/s is decreasing, right?

That is right. If you undervolt, 600W is more than enough.

any of there should do it but id go with the 1000 watt one who knows you may want to add two more 470 or even two more 480 later on.  even buy a 490 next year when they come out.

I would look more into the future then the here and now. I all ready plan to upgrade to 2 1500 watt PLATINUM  server PSU's http://www.ebay.com/itm/684532-B21-684529-001-HP-1500W-CS-Platinum-Plus-Hot-Plug-Power-Supply-/252627974019?hash=item3ad1ccf783:g:hmkAAOSwpLNYAQtI  some time next year. the Psu cost 80 bucks each but i need other stuff unlike atx Psu's which i have now and they run on a 220 line so i will save a little moire power cost wise.

any good 750, 850 watt gold standard PSU can power 4 470 for eth or Zrec mining , i wouldn't worry to much about what the rest of the rig/pc uses power wise if the software miner is written right it should only use the GPU, the cpu should set at 10 % usage or lower most of the time but do ad in an other 20 % for the rest of the pc which should be covered by a 750 to 850 watt gold standard Psu easy.


my rig that has three RX 470 and one RX 480 runs around 562 watts at the wall total before i modded the bios on the 480, i haven't looked yet to see what it does with the 480 modded, i was using a 850 watt gold standard PSU by Corsair but me being me i put that rig on a 1300 Evga gold standard PSU.( over kill  ) , i have that was laying around . for no other reason then it was there to use .

With stock settings 600W doesn't hold 3 of 470s, so I guess there won't be any chance to run 4x470s with 600W. Dunno about 850W.

Did you undervolt the second gear (850W)? Or pure stock settings?

Well, how to undervolt then? What's more important, won't be any consequences after undervolting?

Thanks

Hello,

I have 2 470 rigs, the first with 4x 470 8Gb use a 1000W corsair gold, the second with 4x 470 4Gb uses a 850W corsair platinium.

Roughly, with ZEC, you can make your cards use 90ish Watts when undervolted (not talking gpuz numbers, but at wall), so in theory, a 600W supply should be able to run four of these with a basic system. However, I would not got less than 850W.

850W should be fine with 4x 470s

Hello everyone.
I sincerely ask for help from the community.
Currently I have two PCs mining Zcash/ETH (depends on their market price). Nothing is overclocked. RX 470 have modded bios.
First one is: Mobo p8h61-m le, CPU i5-2300, 8 Gb RAM, HDD 160 GB, 3x ASUS Strix 470 4 GB,750W PSU (80 Bronze).
The second is pretty much the same Mobo (except it has 4 PCI-e slots), i3 CPU, 4 GB ram, HDD 80 GB, 1x Asus 380 4 GB, 600W PSU (80 Bronze).

So I intended to switch PSU, as I checked that each RX 470 has TDP=120 Watt, so that means 120*3=360, leaves about 200+ Watt for Mobo, CPU and HDD. Should be enough. So I switched, but the farm worked for like 2-3 minutes, then PSU turned itself off.
My plan was to use 600W PSU on the MB with 3x470, and use 750W with 4x470 (remove 380 completely).
But now I am a bit confused: I am afraid that if 3x470 don't start on 600W, I believe that even 800-850W PSU (I intended to buy 800W for rigs with 4x470) won't be enough for 4x470.

Again, I don't overvolt/overclock anything, only using modded bios cards.

Do you have any ideas/suggestions on what PSU should be used with 4x470? Should I not try to save money and buy 1000W PSU already for 4x470?

Really looking forward to any ideas. Thanks!
