Hi all,
So much years wandering and finally made the step to build a rig with 6 cards.

Wish me luck on my way to mining.
Anyone using 2 PSUs in the same rig? I saw some tutorials and some people are using a power spliter to run both psus, some are directly plugin both without it.
What do you think I should do? Should I plug the first psu into the mobo and one-two of the cards and the other one in the rest of the cards? Or I should use this spliter for sure? Is there anyrisk If I am not using the spliter? Should I use red button?
THanks!

Is that a single 700 W PSU for your rig?
Sorry son, won't make it.

No, it is 2*700 PSUs, on the picture you can see only the first one.

6*470 Saphire 4g
h81 btc 2.0
ram 4 gb
g1840
2 psu hyper 700w

Nice set up. 2x700W can save you some money.

If you dont have this you should buy:

http://www.ebay.co.uk/itm/131930469208  (great quality and cheap power switch)

Hi,
Thanks!
Can I directly plug first psu with mobo and 2-3 cards and the other 3 cards with the second one without using any additional gadget? I do not want to safe 3$ into buying a split, but it will take time to order and deliver, I want to start mining now
Thanks

Looking good. Have fun mineing :) What coin are you going to mine?

Think to start with eth, decred may be... then will see, I like to gamble

Yes, you can. The only thing you need to do is use a jumper on your mobo cable of your 2nd PSU, and then manually start both PSU.

Eth might be a good horse to bet on. If ETH switches to pos there will be way less freshly created eth.

Congrates man, but i wonder when this buisness get statsified , everyday tons of ppl building new rigs , i think when the prices will crash again and eth turn pos thats will be a day to remember ::)

That is why never invest more then you can lose.
Thnkas! Anyone who can help with my psu question?
Thanks

Plus even if PoS is delayed, they may cut the block reward to 3 or 4 (from 5) to offset the impact of the Ice Age delay. So in most scenarios being proposed, the daily amount of ETH being generated will soon be reduced.

Already answered in post #9. Turn on the second PSU (hooked up to cards only) first.

I'm 99% sure ETH will be PoW forever, and that Vitalik just says it is changing to PoS to FUD anyone thinking of developing ASIC.  ;D

What make you so sure?

Nice Rig Congrats!!! Been pondering for 4 years can't gt myself to pull the trigger to build a rig.

Can it dig a few coins?

Congrats mate. Looking good. Did you run it already?

Sounds like a good trick if true, until now eth doing very well pushing asics away.

I've heard about many people using directly 2 PSU without any sync for months, so I think that you are fine.
Just be sure that the same PSU powers both the riser and the GPU

If you used powered USB riser, it is not a problem.

So how is your rig going? Do you have any ROI calculation ready or is it too early?

Congratulations bro ! It's looking awesome , I hope to get also some sapphire video cards its look awesome :D

I also Pulledthe trigger and built a 4 GPU Rig!!

Got the Asus RX 470 from newegg $600- $120 mail in rebate (had a friend buy 2 so i can maximize ROI)
4 powered Riser $40 amazon
1 new 1000watt PSU 80+ GOLD EVGA = $139.99
$5 for wood to make the case

Recyled old HPE 170T PC which had motherboard and 8GB Ram with i7 860 and the mother board had 1 x16 and 3 x1 PCIE slots so i was capped out at 4 RX 470
also had 128GB SSD lying around so recycled that.

Total out of pocket Inv: $665 Currently doing about $6 on Ethereum per day after electricity cost (620 Watts @0.11cents) getting 95MH/s only modded 2 RX 470 for some reason other ones crashes the system. got 2 Hynix and 2 Elpeidia memory. I have pushed it to 106 MH/s but Energy draw is 680 Watts.

ROI if ethereum doesn't crash and difficulty doesn't rise too fast around 120 days or 4 months.

how many eth you got from this rig ? and how much you spent to built it ? i also want to built some rig

Thanks guys
Currently dual mining eth+dcr on 163mh and 4890 mh 950w power consumption.

Getting around 0.15-0.16 Ether per day I spent around $665 to build a 4 RX 470 Rig.

so with the eth price $48, it will ROI in 4 month ? 1.5eth every 10 days

Yes and No #1 difficulty will rise for mining
#2 Price maybe volatile
#3 My cost was cheaper because i recycled a motherboard processor fan , Hard drive and Ram. you are looking at additional $150 maybe more if you are building the rig from scratch.
#4 Electricity cost
But if the price and difficulty stays stable yes 4 months is realistic breakeven point.

Really nice rig :)

One of the things I like about GPU mining versus Asic mining is that they are waaaay less noisy than their Asic counterparts.

If I had to build a rig myself I would go with a setup like yours.

Cheer

You're getting 163 Mh/s out of your 4 card rig or is it out of both your 4 card rig and your 6 card rig together?

I am getting this speed from 6 card rig only

Nice!  had me wondering there for a min if I was doing something REALLY wrong!

We are 2 different people gondel build 6 card rig i Built 4 card rig which gives me 100MH/s on ethereum I don't do dual mining because it runs hot + higher watts.

I went the route of budget buy spending only $655 to build 4 card rig.

Can you minenx11 etc with asic ? Or is it just gpu farms ?

x11 like dash coin is asics only gpu farms are unprofitable for x11

x11,x13,x15,quark etc are all asics now, very rare to be gpu profitable in those coins.

168MH/S on Eth? This is pretty impressiv, realy nice work man. I wish i had such a miner ;)

Thank you for your help and informative answer. This helps me so much. What coins besides cryptonote see none asic ?
Obviously excluding eth.

There are alot of small or Altcoins they are good for GPU mining AMD gpus rock for ethereum and Nvidia GPU are good for Equihash based coins such as Zcash, Zclassic, zen cash etc.

congrats on new rig, seems great. Just wanna ask, is there any reports about ASRock d1800m or ASUS N3150M-E
, and so integrated CPU mobos, do they see all 3 GPUs?

PoW Ethereum Classic Yes, but according to this article https://btcmanager.com/buterin-confirms-ethereums-proof-of-stake-75-percent-complete/
It is a plan to change ETH to PoS not a FUD.

it's onyl a plan not guaranteed, i think they will change their mind again when near the activation, like they did in the past, the pos was planned long time ago but was always delayed, for good reason, they will do it again, its a mistake to go pos on ETH imho

I think it is a well known plan.
