from the picture it shows a few question...
1. Why do you need such high powered PSU?
2. Why the expensive board with 7 slot but only 5 boards on each setup?
3. Pros and Con about your risers.

The riser you've shown seems surely more capable than the previous, old, one but I haven't tested them so I cannot talk for experience. How long are you using them? RMA/DOA rate?
Keep in mind that such a riser it's just useful if you've got low powered VGA's with ordinary psus. I'll have in my systems custom ones, much more complicated and potentially interesting.
i never had any issues with chinese riser, i still have more than 50s 1.5 years old chinese riser still running, and 72s new one installed and its been running for 7+ months the only issue are with RX series GPU, but its not on the riser, its on PSU cable delivering power to the riser, since RX series take more wattage than previous generation. with RX480 6-pin reference or RX470 6-Pin Reference, it will eat more than 90W through the riser power on peak usually with will make Molex or SATA cable burned on PSU end point

The cards are a bit too close for my taste and there's a lot of vertical space wasted but it does look good.
I agree. I did an experiment about 3 years ago and found that the optimal distance between GPUs was 2.5x the width of the GPU. The cards were all dual fan 7970s and 280xs. It may be different with your cards. However, I can suspect that supplemental cross-cooling will be needed more than the picture displays. i disagree the distance mean not too much if you are going to put 3 fan in front for pushing air between them, actually it's better to have them close enough to make the tunnel effect better It really depends on the directions the cards pulling air from and pushing air to. In my experience high airflow between cards is worse than cards having space to pull air from (Windforce 3x).

Yes, they are close, that's true, but at last I have to say that it is impressive. I'd have attached PC case fans to the metal front bar, but that's because I like them so much.

I would think that it would be more expensive than the chinese made once. I am getting the chinese risers for about $3.5 each. Let us know about your price and pro and con about your risers.
Hi mewhoyou I'm happy for such, that price it's almost costless. As I said I made these risers pretty much for myself, the farm I am going on to build. Given the insertion of them in some projects of mine, like the Venus Prime Unit, and future projects, I am in need of reliable, available units with a top notch quality and features. I own 70 chineese risers and unfortunately I am very disappointed about the general quality, given an high DOA and RMA ratio. There isn't a single supplier and I need to purchase them in china directly, something not compatible with my business. They will be inserted in my solution, in a leasing project with my investors, and given some patent on them they won't be available soon. Instead I could sell the other adapter, right in the motherboard, but it's premature to talk about prices. Let's say that money, with my business, doesen't come from that element from the picture it shows a few question...
1. Why do you need such high powered PSU?
2. Why the expensive board with 7 slot but only 5 boards on each setup?
3. Pros and Con about your risers.
would you be so kind to write them in the thread in my sig? I would appreciate that, also because this isn't the proper place. I wrote you there https://bitcointalk.org/index.php?topic=1586147.0I'll respond you there from now on, to such questions Have a good day

I tend to use reliable and heavy duty components, it will pay off in the mid-term. You're right and I agree with your statement about the AMD's; in the first models it was an engineering mistake due some fulfillments about HTPC's electrical standards. They simply made a, giant, mistake, and understimated the power consumption of the chip probably (leakage) The main issue in this sector is that the hardware solutions are adapted from the consumer market, and it's not a good thing considering the power and thermal needs of the altcoin mining scene. The ATX PSUs aren't made for such 24/7 loads, they tend to fail in the long term and haven't got many critical features that a dedicated solution (that still doesen't exist) could handle. One of my projects is to build a very capable power delivery, with dedicated VGA PSUs and another concept instead of the risers, that we are idealizing. They will be offered in the ecommerce portal of my company, when ready.

It may be different with your cards. However, I can suspect that supplemental cross-cooling will be needed more than the picture displays. Blower fan cards can get away with closer spacing, as they direct the hot air AWAY from the other cards. Fan-type would work better with more spacing. A fan blowing air at the intake-side of the cards along their axis helps in either case - and if you have enough rigs stacked vertically it makes for a great place to put a room-type fan to blow LOTS of air. If you attach a fan to the "metal bar" that should be set to suck air OUT, as that's NOT the "intake" side but is part of the exhaust, even with fan-type cards.

Thanks all - glad everyone likes it! In answer to a couple of the questions; The things sticking out of the cards are HDMI dummy plugs to simulate monitors - if you see in the background, most of the time I only have one in a system (on the card in the 16x slot). But sometimes when I'm tuning or tweaking things it's convenient to have it in each device. The PSU is the DPS-2000BB with these breakouts: https://bitcointalk.org/index.php?topic=1667131.0along with these adapters: https://bitcointalk.org/index.php?topic=1627191This gives WAY more power than the system needs, even the older ones with R9's - plus all in you're still talking sub $200 for 2000 watts of Platinum rated power, pretty hard to beat. I'll probably be making one more slight mod to it - basically rotating the motherboard 90 degrees and changing the height of the unit from 14" to 11". This will give better airflow from the large fans (they're staggered right now), and I originally did it so I could run full size boards but the reality is I only run one rig like that, so I'd rather have better fan coverage. Because I'm overkill on cooling, the machines can run in temperature conditions that are much higher than normal. I also think it's not really accurate to call it an 'open frame' case, as basically all sides except the back are enclosed - it's just a much more spacious case than you typically see. Oh, and for those interested in the 'Mines' signs, I got them here: https://bitcointalk.org/index.php?topic=32469.0

Just a quick question for all you guys running big rigs at home, do you have any trouble/concern about the power to the outlets in your home? I have 2 rigs one with 5x1070 and one with 3x 480 and 2x 470 and all together they pull 1200 to 1500w at the wall depending on whats being mined. A standard residential circuit is 15A so maximum 1800w, I'm just wondering if pulling 1200+ through a single circuit 24/7 is a recipe for disaster

it really depends on the wiring in the house stay at 80% max load. and youll be okay
