My first two racks of dedicated machines are full... with these plus the others scattered around the office / at home I have 101 total GPUs online. I've swapped cards in a few of the systems earlier to reduce the amount of AMD cards I am running... it's likely I will swap almost all of the AMD cards to GTX 1060s or 1080s. ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fsundownaudio.com%2FBITCOIN%2520PICS%2F0719171041_resized.jpg&t=665&c=u9EVXwZJ-bOrCQ) Are you running 3 GPU's per rig? i was looking at your picture it looked like you had 1 gpu in the system and 2 outside on what appears to be flooring planks? Question for you on the power, how come your using the internal PSU over external PSU on the GPU's? I ask because the system has a very low quality PSU in my understandings that wastes away like 20% of energy as heat above 50% load.... i have been running mine all on external server PSU's because of this issue to try to cut electricity cost.

I ask because the system has a very low quality PSU in my understandings that wastes away like 20% of energy as heat above 50% load.... i have been running mine all on external server PSU's because of this issue to try to cut electricity cost. For RX480/580, GTX1070, and GTX1080 I am running 3 per rig. For GTX1060 (and my single RX560 system) I am running 4 per rig. I have replaced all the PSUs in everything other than the Dell's with 750-watt Platinum PSUs (using factory 875-watt Silver PSU in the Dells) -- they are still very efficient at the load range I use them at (I keep them in the low 500s range [adjusted with a Kill-A-Watt] where they test 90% even when hot): http://www.anandtech.com/show/9928/the-rosewill-quark-series-psu-review/4Basically I want each system to be a completely independent and usable system so I am sticking with standard hardware. Also if one system has a problem I'd rather it be completely separate from the others so it doesn't take down other systems with it. Not that the server PSUs are a bad idea by any means -- just not what I wanted to do.

NiceHash added "Keccak" to their new updated client. My nVidia cards are doing awesome on it -- my remaining AMD cards... not so much. My pay-rate has been a roller-coaster since then, haha... but largely in a good way (the really sharp dip is where I briefly shut down my network switch to install a new UPS on it): ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fsundownaudio.com%2FBITCOIN%2520PICS%2FKeccak.jpg&t=665&c=LlcS9RnzjtMtPA)

Also seems that "Keccak" is a real winner on my GTX-1080 machines --they have been sticking to it pretty much all day since the update to Nice Hash enabling it.
Alot of people seem to have avoided the standard 1080 like the plague... but I've been pretty satisfied with mine.

so your go to machine is the T5500 hopefully getting the 875 or 750w factory power supplies from dell, using sata to 6+2 pin connectors and risers and 1060s, 1070s, or 1080s correct? This setup looks awesome I just have a question about the power did you install a power distribution unit kit or all separate receptacles by my calculations if each rig is pulling 600 watts you could put 4 on a 20a breaker or 5 on a 30 to give some headroom? I have a couple rigs setup using the 1200 evga platinum and looking at new housing for the other RX cards I have and these look like good ideas

what are you getting per GPU? I see it only making $25 per day for 8 cards.

The ones I am using are all 4x GTX-1060 so I use 2x factory 6-pin + a CPU Power to dual PCI-Express power adapter. They also have the 875-watt PSU. My actual go-to is the HP Z400 -- although I have to change the PSU I actually prefer the internal layout (more open). As for the power -- I am running 8x 20-amp circuits at the moment. I have each system tuned to be 500-550 watts. I am trying to keep it down to 3 per 20-amp circuit for plenty of headroom.

what are you getting per GPU? I see it only making $25 per day for 8 cards. It has varied quite a bit -- for the first few hours it was around 4-5 dollars per card / day. As of now my 1080 machines have gone back to other algos that are running 2-2.50 per day or so. I suppose time will tell if Keccak goes back to the higher figures =)

It'll be nice in the winter time to keep that area warm, haha!

Hey, really intrigued buy your guide and wanted to pull the trigger on a z400 with 4 gtx 1060s for my first system. I've only built a computer once before and this part is the only thing thats giving me some trouble. Is there any guide you can link showing how this is done and why its needed? Don't these refab computers you linked come assembled? why would they give you a power supply that doesn't work with the motherboard? Also any chance you could make a short guide on onboxing and connecting the gpus and innitial start up? understand if its to much work but I'd be willing to send you a xmr donation once I'm mining if you can help understand this better. thanks

My secret is, I pay a little more and buy DL580 G7s for $500 -- $125/mo monero cpu mining and up to 12 GPUs without a breakout board. It also comes with 4x 1200W PSUs. Just make sure to buy some ear plugs so you don't go deaf.
Looking these at ebay I have hard time figuring out what is needed in order to fit 12 GPUs in to one.. some kind of PCIe riser board? Also they do have 4x powers but how about connectors for powering the GPUs? -- Tigel

I need help with my Dell T5500 Rig, I'm trying to set up 3 RX580 GPU on it, I ran into problem when trying to power up all 3 of the RX580s, I bought the "8 pin CPU to 6+2 PCI Adapter" from Amazon for the third GPU, however when I connect the third GPU, DELL T5500 does not want to power (the power LED flashes orange a few times and it powers off). Why is the CPU power not powering the GPU using the adapter?
I have no problem running 2 of the RX580s, they are power by 2 of the 6 PIN PCI Cable using 6PIN TO 8PIN adapter.
