Is there any way to salvage what I currently have ? Looks like the best option for me is to use the cable that comes with the Psu, 6-Pin to 4-pin molex (female).  Basically powering the riser directly from the psu, i read that 2 are ok per line.

Any other suggestions would be appreciated 

Thanks for the replies, unfortunately I don't know how to manufacture cables or how to modify them.

I keep coming across conflicting info which is making things very confusing. I have 20 Ver007 risers with SATA/Molex cable adapters.

I keep finding info that the SATA/Molex cables burn a lot and they're rated for ~50W and the GPUs pull ~130W. Based on the numbers this makes sense, I'm still trying to figure out how much wattage goes through the cable and how much goes through the power cables that come from the PSU directly to the GPU.

But I also see a lot of people buying these risers with SATA cable and use them in their 500 series rigs. I don't want to gamble with 20 GPUS and risk burning down my house.

What are my options as far as powering these risers? (Besides using the SATA cables that tend to burn a lot)

Sorry for putting this in the wrong section, I was rushing when I wrote this.

This is the PSU I am interested in: https://ca.pcpartpicker.com/product/dFdFf7/corsair-power-supply-cp9020070na

My problem is that the PCIe risers are powered by a Sata-to-4Pin Molex cable. I keep reading that those tend to burn so I am looking for an alternative. I was thinking of putting the 6 pin from (this) and plugging in two of these (this).

I'm not quite sure how the splitter would help me. Can you please elaborate?





 

I want to build three rigs with 6 RX 570s in each and I'm trying to figure out how to power them properly.

I bought a bunch of these guys (ver007): https://www.amazon.ca/6-Pack-Powered-Riser-Adapter-Extension/dp/B01N3UVJHM
and I was going to power the them with this: https://www.amazon.com/Cable-Matters-2-Pack-Molex-Power/dp/B01DV1Z22K/ref=sr_1_3?s=electronics&ie=UTF8&qid=1494962381&sr=1-3&keywords=6+pin+to+molex from the PSU directly because I've been reading that Molex/Sata cables tend to burn because they're not designed to handle so much power draw.

However, a lot of people are saying that you have to do the finger-temp test after a few mins of mining to see if the sata/molex cable is hot, if it isn't then it's gonna work fine.

There's also this: https://www.youtube.com/watch?v=TataDaUNEFc
~@2:00 mark he tells how to spot the good and bad cables.


So what should I go with? Any help would be appreciated!

I will attempt to build this 7 GPU rig once I'm done exams at the end of April, however if 7 is not possible, 6 will have to do and there's many confirmed builds of 6 GPU systems

That's what I was hoping for! 

I'm open to 470s, do they need to be 8GB vs 4GB? I know the 8GB pulls a bit more power from the wall but if the difference is only a few MH/s and Id rather save some $ on the hardware. I've seen the 8GB reach 31 MH/s while the 4GB max out at 27-28MH/s

I called a few places in Edmonton, even in cities near by and take the shipping charge, and only one store in Toronto was willing to give me a deal. Unfortunately, it still came more expensive than buying locally at full cost.

I was hoping that the 480s go on sale while the 500 series takes over, but I don't know if that will be possible now.

I live in Canada and 2 of my friends want to build a 7 GPU mining rig with me like this one: https://forum.ethereum.org/discussion/11404/msi-z170-7-gpu-bios-setting-step-by-step

I am looking to get ~20-25 RX 480s and I am wondering where can I get such a large amount of GPUs since most stores only limit it to a few per person.

Yeah unfortunately I don't see the benefit of joining the game today. I shall continue with Forex then haha

Thanks again everyone!

I tried a few, and I am getting ~4$/mo with one U3...unfortunately this does not make it worthwhile. Meaning my initial theory about me being too late in the game is true, so far it does not look like this is a viable option to make some money.

Hmm I was hoping the U3 would give me a bit more return. Then again, I am competing with 100K farms...
I'm going to do more research on my own, but from what I'm getting it seems like I am too late to join the game in order to make some good profit. Even with one or two U3s, I'm going to be earning ~4-8$/mo....which in a year (assuming bitcoin does not drop) will only cover the cost of the hardware (~100$).

Are my approximations OK or am I still missing something?

Thanks for the replies!

I have provided 2 screenshots of my results after leaving my laptop to mine overnight. After reinstalling MuliMiner, my hashrate didn't drop, but my worker kept going on/off (see #2) - still trying to figure it out (my guess is the heat - laptop is forcing itself to cool before beginning to work again)

I appreciate the advice of not going with BFL - I have found an Antminer U3 (~60GH/s) that I will look into.

To answer some of your questions:
-I am mining bitcoin
-No I am not trolling you, I live on university campus and don't pay for electricity. I will be here until Apr 2016 so I figured I'd have something running 24/7 while I'm at school
-As mentioned, I am merely familiarizing myself with the software, pools, and everything about BitCoin Mining, hence using my laptop. Once I figure things out, I will purchase an ASIC miner (USB ideally) and start mining.

For a newbie, would that be a good miner to start with? I saw some USB ASIC miners that advertise ~1GH/s but pricewise it is better to go with the ~60GH/s one (at least IMO)

Thanks again for your replies!  

I live on uni campus where I don't pay for electricity. I was looking at 5GH/s Butterfly Lab ASIC miners. As far as laptop, I want to set it up so I can just plug in the ASIC miner and go.

Only debating between buying 2 (5GH/s) miners or start with one.

Thoughts?

Will do, anything else that I should look into?

Hello everyone,
I am new to bitcoin mining and I have a question that hopefully you will be able to answer.

I am currently looking into ASIC Miner but I decided to try out mining software on my laptop first. I know this is not recommended but I am simply testing things out before I purchase a miner.

My laptop has an NVIDIA GeForce GT 650M with 1 GB of GDDR5 SDRAM card and I am using MultiMiner as my software. When I first ran the program I was getting about 38Mh/s, now it dropped to ~600Kh/s

My question is why the huge drop? Could it be the heat?
