I'm not sure if the psu is a lemon replacing the cords fixed everything. None of the cords are permanently attached to the psu. Is there a test I should do to just make sure?
well you might not consider it a lemon, but anything that doesn't work out of the box as it should, then i consider it a lemon. it shouldn't require your time to diagnose, then fix it the problem. so do you know if it's the power cord, or if it's the pci-e cable that's defective? power cords are easily replaceable as they can be found anywhere, but the pci-e cables are only specific to this certain corsair series. |

hmm looks like a lemon PSU then. i'm surprised that happened to corsair's highest end PSU

Well I figured out what the problem was. Apparently two different wires were bad lol...
which wires were bad? on the PSU? |

here are some closeup shots of little details you might want to see the top bar is tapped with threads to fit the regular computer screws. this is to secure down the cards from moving around. i just measured and drilled holes into the bars, then just used the actual screws to make the threads directly into the aluminum. this freakin took like 2 hours    here's what i used as motherboard standoffs to raise the motherboard from the aluminum frame. drilled a hole in the frame, then put a long screw from the bottom up. a washer and nut was put on top to secure the screw, and also act to raise the motherboard up.  the excess end of the screw sticking up through the motherboard holes prevents the motherboard from moving around.  pic is a little blurry, but it's just to show that an optional nut can be added on top of everything to bolt down the motherboard. i won't be adding this extra nut in the final build since the screw is long enough  here's a random nice little froggy in my back yard watching me when i was building this rack  so i ran into a couple problems when doing this build, and i'll post that next time i have pics up |

You should upgrade to the MSI bing bang boom x58, which has 8 pci-e slots.
lol right? the naming of the motherboard is pretty lame haha. "BIG BANG KABOOM" will be the new x79 socket LGA2011 for MSI. it will have 12 pci-e slots  . /sarcasm i will probably copy your design and modify it to fit my needs  it's copyright, there won't be any copying unless you pay me fees. jk. copy all u want, i'm interested to see what variation you come up with. what did you plan to change from the design? be sure to post pics when you have them! Just had my Big Band Marshal arrive so i'll be doing something similar to this  that's crazy, you bought a $400 motherboard for this? it would have been cheaper (including other components like CPU, PSU, etc) if you got 2 separate rigs instead of this one 8-slot motherboard setup. and just a heads if when you build something like this, you won't be able to fit all 8 GPUs on top when using a standard 17cm riser/extension cable. it's not long enough to reach the two cards and the ends if you leave a slot for cooling between each card. you'll need to break it down to 6-7 cards on top and 1-2 cards on bottom, unless you connect two extension cables together to make them longer. Looks nice. But wouldn't the motherboard flex too much in the middle when you plugin/unplug pcie extenders, for example. I might like to see more support for the motherboard middle (like plywood, that might ruin the look though), but if you're careful maybe wont be an issue.
nope, doesn't flex too much. it might be a problem if the video cards are directly on the motherboard and weighing it down, but since i'm using extension cables, they hardly weigh anything. the CPU cooler weighs the most, but i'm not using a huge tower cooler or anything. there's nothing else on the motherboard to push it down, so flex won't be a problem. haha it doesn't take hercules to plug in the extension cables, so that won't be a problem either ps- this forum needs a multi-quote button. i just had to manually quote everyone in this one post |

i think you really only need 2 pci-e slots on the motherboard, a mATX motherboard can only fit 2 double slot GPUs. why are you looking for a small mobo with 4 pci-e slots? unless i missed something  |

what do you mean shows 18 GPU? does it show this in the CCC or device manager? if you're using the latest drivers, it shouldn't have this problem. maybe try to uninstall all AMD drivers, use drive sweeper to wipe everything clean, and install the latest drivers again
lol when i read the title, i though you somehow got 18 GPUs to mine in one rig, which is pretty much impossible right now with the driver limitation. current AMD drivers can only address 8 GPUs right now, so i expected to see something crazy in this thread... but guess not haha

i've had several people i've had successful transactions with on here. anything in bold were exceptionally great transactions:
SNAPCALLHERO: met up with him in person for a pretty large purchase of many items. he gave a deal for buying multiple things.
wizang: bought a video card off him, he shipped after payment, i received a couple days later, card works great.
ataranlen: he bought an unused game off me, he sent the BTC and i sent the code, very quick, easy, and hassle-free transaction
deslok: he bought a KVM off me, i couldn't find all the cables it came with so threw in some mismatched cables and he was ok with it, shipped it out and he received it.
cuongnq: very negotiable and i bought several brand new things from him. i had several transactions with him, not just one.
pigki: i found out he was local to me, so i met up with him at his house two different times for 2 separate purchases. great guy to meet with in person, had a small chit chat about bitcoins also.
bob777fred: one of the best transactions i've had. he was a new member, had no pictures of the item, and had no prior transactions or feedback, so i asked him to ship first. not only did he give a discount for buying two, but he had huge balls to ship me 2 video cards before i even paid him. it takes a lot of trust to do that, so i fully vouch for his legitimacy.

i also use to use VNC, but i found that logmein works better for me.

Nice setup! I know what you mean about "this should only take a couple of hours..." Do the PSUs draw air in from the top? If so does the motherboard block air flow to them? Did you find a single rivet strong enough to hold the aluminum angle stock together? ya i planned the PSU to pull air facing up. there's a few inches of clearance between the PSU and mobo, so that should be enough room for it to breathe. i haven't drilled screw holes in the frame for the PSU mount yet, so i could always just flip it upside down and let it intake from the very bottom, but then that means i'll have to somehow lift the whole rig an inch so it has breathing room on the bottom. i'm probably not going to do that because that will raise the overall height even more, which i wanted to avoid. i measured everything to be as short as possible. as for the rivets, i used steel rivets instead of aluminum rivets. a single one at each joint is more than enough to hold everything together. if i used aluminum rivets instead, then i'll have some doubts because i test-lifted the whole frame with 2 PSU, mobo, and 7 GPU's and it's pretty dam heavy. |

That still doesn't answer what your doing with the 8th card lol oh i guess you missed the edit while we both were typing. just to clarify, the MSI big-bang X58 is different than the MSI big bang Marshal: MSI big bang X58: 7 pci-e slots, socket 1366, i'll be using this in the buildMSI big bang marshal: 8 pci-e slots, socket 1155, i dont have this board |

only 6 slots on mobo. How you plan to use 8 cards?
lol it actually has 7 slots: 6 pci-e x16 and 1 pci-e x1 on the very top. i think you were just basing what you said on my pics, which is hard to see that top black pci-e x1 slot. here's the newegg link for specs: http://www.newegg.com/Product/Product.aspx?Item=N82E16813130289i mentioned in my first post that i'll be using 7 cards, not 8. the 7 cards will be on the top, but i just noted that the 8th slot is on the bottom next to the PSU in case i'll ever want to upgrade the mobo to something with 8 slot pci-e |

i started on the small DIY project about 2 weeks ago with the assumption that it would take 6 hours max. it shouldn't take too long right? all you have to do chop up some bars and piece them together. boy was i wrong... i've spent nearly 18 hours on it and not yet fully finished. it's a pretty straight forward process, but just very time consuming. i only used very simple tools, nothing complicated: - dremel (with cutting disc, and drill bit)
- rivet gun (with rivets)
- ruler
- pen
- screws with washer and nut
- 2x 8' aluminum L-bars
i'll be using a MSI bing bang x58 motherboard, which has 7 pci-e slots. i built this rack to fit 7 GPU on top with a full slot space in between each card for breathing room. there's also 1 additional space for a 8th GPU on the bottom, next to the PSU. there's only 2-3 motherboards with 8 pci-e slots (including the MSI big bang marshal), so most likely i'll never use these motherboards, but i just made that 8th slot in case i'll ever need it. it's not completely done, but i'll snap a few pics of what it looks: empty frames   this is going to be a double PSU rack, but i have not drilled holes for the screws yet. it's just soft mounted right now.  mounted the motherboard  a closer shot, you can see i used a long screw with washer and nut to use as the motherboard standoffs. after the motherboard is mounted, i could add another optional nut on the very top to secure it, but i didn't think this was necessary. the screw is long enough, the motherboard won't be popping out.  2 GPU's mounted  these next few pics is just for lulz. the GPU's in here are NOT going to be used in this exact setup.  7 GPU's test-mounted on top  this shows 8 GPU's total, 7 on top and 1 on the bottom next to the PSU  closeup of the one on the bottom  a shot from the back  more updates to come when i have time, the rack isn't finished yet.... |

wrong section buddy |

one thing to note is that if you file something with ebay and lose, THEN go to your credit card company to file because you lost, credit card companies will pull money from ebay/paypal and ebay can suspend your account just for doing this. ya... they're douche bags in this sense.

Why would they? They will continue to put their orders in, and if miners continue to sell at outrageously low prices, traders will continue to buy. If all the miners secretly got together tomorrow and halted selling for 2 weeks the price would double. However this is a small market, and when you have thousands of people trying to make back thousands of dollars in equipment things will get ugly fast. The market is being flooded by cheap coins because of the new miners that have come into the game. Anyone who bought in with equipment should seriously consider holding on to their coins for at-least a couple of months, cause selling now doesn't help anyone including themselves...
I think the biggest problem is that you have a bunch of finance people literally praying on a bunch of nerds (I include myself thank you). They know how to manipulate this small market, and seriously work us to their advantage. The money that we trade on a daily basis is JOKE money to these people. You think your $10,000 is hot stuff? These people have millions... And they can easily manipulate us into making stupid decisions and giving up our Bitcoins for prices that are simply unacceptable! Just because your fiat reality has you under the ropes doesn't mean your Bitcoin reality needs to look the same way...
We are a community of IT professionals, and IT people are known for knowing "everything". It's time for everyone to start picking up some day trading books, and learn how trading markets work. I don't mean that in any detrimental way, but the facts are true. These *firms* are running huge games on us, and everyone seems to be following them like lost puppy's...
cool story bro |

what you're describing is pretty much the same thing as escrow service

hey, how many are you looking for? please tell me ASAP, i can get a deal on a few of these but i'm only offered this price for only another day or two and it will expire. all other brand new 5850 supplies are exhausted in the US as far as i know. shoot me a PM and we can talk about it. refer to this thiread for more info on the deal i can get: https://bitcointalk.org/index.php?topic=32886.0 |

OP, you have good intentions doing this, but 3 BTC isn't going to do anything. just look at the market depth and see how puny your 3 BTC is.
