Working with a TB85 motherboard I am going to construct an energy efficient GPU mining rig. The collection of materials is as such;

Estimated 1800 h/s Equihash

Using the TB85 motherboard I will have to some bios configuration in order to use the PCI-e powered riser boards. I have been reading about a recurring issue with the TB85 needing to have the 5 PCI-e slots bios settings modified to 2.0, from the default 1.0. I personally have no experience doing this and the bios configuration will be the focus of Building a 6 GPU Mining Rig #4 which will be posted within the next week.

Assembly

I have mounted all 6 RX 570 cards to my TB85 board directly, then suspend 5 on PCI-E risers to the metal rack I am going to construct. The Power supplies take up the most room technically, so the case will be basically a rock system to support a board, 6 GPUs, and 3 PSU's.

Innovation in Efficiency

When I built my first mining rig from scratch in 2014, I managed to get 1200W power supplies to run 2 GPU's, a hard drive, system fans, and the board. Now in mid 2017 I am getting 6 GPU's to run on the same 1200W powersupply.

Antistatic

It's important to keep antistatic guards in place for this large of a mine. I have no issues installing a rubber Matt I cut into pieces the perfect size, but there is alternatives. I just saved some $¥£ here buying a thin rubber mat from Home Depot.

Location

This kind of mining PC is safe to run off a surge protector, I usually like to buy a power bar with a watt meter of some sort on it, it makes live readings way easier. I found that Woods has this nice line of products on its WION line. They allow you to use your smart phone to check wattage, so you have both you hasrates and wattages in the palm of your hand for IT refference. It's a nice feeling when you're travelling to know what's up at the high wattage machine running at home. I use AMD software to monitor temperatures.

The ratings usually have these new AMD cards running at 100 watts at full capcity.

Cost Evaluations

TB85 6PCI-E Motherboard : $110 CAD
6×Red Devil RX 570 GPU's : 6.55 ZEC
12×PCI-E 1x to 16x PCI Risers : $150 CAD
ATX Power Module $25 CAD
1200W Platinum EVGA PSU $400
250gb SSD $160
Galvanized Steel Racks, Washers, Nuts & Bolts $225
Used Intel i5 1150 Socket CPU $150
Rosewill 1150 Socket CPU Fan $30

Totalling : $1450 CAD + 6.55 ZEC

Energy Efficient Mining

In order to be environmentally responsible for any Co2 emissions in Canada, I will be dedicating all of my GPU's to the most energy efficient hashrate. I chose to use an EVGA 1200W fully Modular +80 Platinum rated powersupply for this reason.

Internet

Wired Internet is best for mining as wireless frequencies can be hacked. I usually put my mining machine IP addresses on low priority in my router settings after its running stable hasrates. This helps keep network traffic down when I am gaming or browsing youtube while my mother watches netflix.

I have a bunch of cat5 and cats cable laying around luckily, but this stuff is only about $0.50-$1 per foot in Canada.

A Sneak Peak at the Finished Product

If you're a miner, with any experience level, and want to get involved with a new decentralized pool & exchange developed by an international team of freelance software engineers who will be redistributing used computer parts for mining follow @phusionphil or go to http://www.phusion.top in order to sign up for our early access program when its launched this year.
