How do you hook up the 4kw psus? Do you use one per few rigs with 7 cards?
You sure move fast Reelen. I know you took over 12-14 rigs from a hosting site but building 16-18 rigs in that short of a time is amazing! Yeah, can't wait to see your Sexy RX480 Nitrox light up. I believe you also purchased some of those 4KW server bundles as well. Show off them sexy 4KWs too if you got some pics. You're definitely Vega 10 ready with those PSU as it wouldn't matter if they are 150W or 350W for each GPU, we're ready!
P.S So many extra rails arrived!!! Packing 1 box and shipping it to you now for your Sexy Rack. Back to work I go, on my rails.

Nice psu & fans recommendation, i will check it out if possible ! 
That actually can be very awesome for a controller to put a few of Finksy Fan in front of my standard 4 ft Rack where I can control the intake fan power base on heat. Much sexier than Box fans. =)
I have found a good fan controller.
It is a ham radio power supply. 4 to 15 volts. 25 amps constant.
That would help sound levels on all three fans in the thread.
Links to follow.
here is what I have now $59.95
http://www.ebay.com/itm/JETSTREAM-JTPS14M-12-Volt-4-16V-Variable-12A-14A-Max-Switching-Power-Supply-/192080751641?
just purchased this one for 95 with shipping included
http://www.ebay.com/itm/131536990208?
the jetstream is running 9 stock .8 amp fans in the pandaminer at 9 volts zero issues.
it could run 2 maybe 3 papndaminers
the newer stronger psu an mfj should run up to 5 maybe 6 pandaminers 4 to 15 volts 9 is sweetspot.
these could run lots of finksy's fans

They are beast. It takes a lot to impress me but boy 3 of these move some serious air. For the small extra wattage I think they are definitely worth it as they will definitely work in any environment. I'm actually using them on my top rigs just to move the air toward the attic exhaust fans better and not recirculate back to the intake side as much. Please do share more info when you get the Pico working, I'll be first in line. I have 2 of the 4KW PSU bundle just itching to use it. Very excited to test with the PCI splitters to allow the 30 connections to become 60 too. PCI Risers will always be better than that crappy cheap SATA to molex cable that can either melt or come loose and catch on fire.
I'm sure we all have this issue!! This is why I only buy from Hawkfish007 for risers. Fast USA 2 days shipping and he stands behind his products. I've ordered over 200 risers from him hardly have any issues vs the cheaper quality risers where you can literally feel the SATA to molex cable burn your hands. Those will surely eventually catch on fire. I've got burned with so many bad risers it's ridiculous so learning from experience, I only stick with reputable vendors and fast speed is critical to us miners as 1 day of idleness = lots of money that can be used on accessories / risers.
On a different topic..............
*******Friends********* - If anyone have good ETH ROM for the MSI 480 RED or Armor 480 that is stable. What I mean by that is, not a ROM that is just copying mem strap from 1500 downward or pushing memory beyond 1950 where it's good to use and show off for a 1 GPU setup but is very unstable for a 6-7 GPU rig. Please PM me. It's been a while since I been mining Eth on the 480 and my 480 ROM is tailored toward ZEC. Also Sapphire Nitro RX480 8GB, not sure how I have just 1 of them in my farm. Maybe a Black Friday special. Forgot. Any help there is appreciated as it's been a while and I really barely have sufficient cycles to even finish setting up rigs, so I don't have the tweaking time as I did in the past but I know they can do 27-29MH easily. Thanks...............

Hey Nhan! Sorry it took me so long to jump in here and congratulate you like everyone else. I'm just so used to sending you desperate S.O.S. messages about my own crap that I never look you up on the forums 
Your never-ending drive to improve your mine (No, it is no longer just a home) may border on addiction, but it is absolutely inspiring. Every time I think I have a good idea, you are always 3 steps ahead of me 
One of these days I'll catch you off guard! Until then, I'll just keep taking in the scenery.
Anyways thank you for the shout-outs, it's much appreciated. Nhan is by far one of the most hardworking, helpful, patient and generous people I have the pleasure of calling a friend. He might only surpassed in patience by his own family. He's the reason I'm getting more involved in the GPU scene these days, and like he alluded to I am about 99% done getting components together to offer full GPU rig packages by server PSU's. I am just finishing up some testing right now and have a few more custom cables on order. I am currently helping a customer deploy over 700 GPU's in a DC, so it will be a good large-scale test-bed for the DPS-4K to power the rigs without the use of baby ATX PSU's.
As for the products I have, the DPS-4K PSU's can be found in the link in my signature. I will be starting a new thread strictly for GPU rig powering and the bits required for it, should have everything together in about a month once my customer has everything off the ground. Those 120mm fans Nhan is testing can be found in the DPS-4K thread as well, I now include them with the PSU packages I offer. I could have (and if it were up to Nhan I should have!) gone with a lower powered fan. But I wanted to stick with one type and offer something that could be used for cooling full server chassis, used as a replacement fan for S7/S9's (probably require some underclocking though), cooling the 4K PSU's in ANY environment and under ANY amount of load, etc. I prefer over-doing it, even at the expense of more power consumption.
Anyways, thanks again Nhan. Once I have everything in hand I'll be sending another care package your way so you can see for yourself how nice it is to break the dependence on ATX PSU's altogether.

Sweet, thanks for the info.
Looks like I'll have to hit one of them up for some fans

The other ones are still cheaper to buy then bulk discount with scythe. Even if they are the same price, once you try the fans, I think you'll be more impress with them. All 3 are great but I dont' think the Scythe deserve the cost premium. The bulk discount usually requires high volume else the discount isn't too much for Scythe. For the other 2 fans, they are design for volume so it's easier to negotiate volume discounts. I had to haggle a lot for my Scythe and in the end they tried to raised the price after we agreed, so I got pissed off and canceled. I end up paying more from another vendor but I was ok with that as I hate shady business practices of bait and switch. It goes back to my convention of if I can buy from the same quality vendor, I will always do that. If I can do that AND it's from a FORUM member and I can help our community, that is GOLD. Needless to say I'll only be buying my fans from either Finksy or Hawkfish going forward.
Were the resold ones cheaper than the scythe ones or is there a place to buy the scythe ones in bulk for a discount?
Other than the Scythe fan, the other 2 you have to buy thru a reseller which is either Hawkfish007 or Finksy. You can PM them for more info.
It's best to reach out to Finksy who is a senior forum member as prices do change. However he's very good at keeping cost low. The PSU is made of 2 x 2KW IBM Server PSU and are combined using a breakout board that have 30 PCI connections. Finksy also sell a custom FAN mount to help tighten the connection between the PSU together as well as mount your fans. They become a 4000W PSU that are very beastly and can take on any GPU rigs you can throw at it. They do require baby PSU to power the power risers and Motherboard / SSD. However he just teased me with this PCI powered riser and a Pico ATX Psu option to allow straight up server PSU power config only as well.
Riser Teaser - Pico teaser to follow soon.
So I was looking to buy over 150 fans to cool my server case rigs as well as my IBM server PSU. Previously my go to fan has always been the Ultra Kaze 3000. I end up ordering hundreds of dollars worth of these fans, just to hear from Finksy and Hawkfish007 saying " NHAN, I got these FANs, you must check out!!!" They both send me a bunch to review. I must say, I will never go back to Ultra Kaze again. The Ultra Kaze are great fans but they are not ball bearing and typically cost $15+ each which adds up fast when you need 150-200 of them.
Hawkfish007 Fan
FAN in the middle
These fans are ball bearing so in theory should last longer than the Kaze but time will tell. I really like them and they're about the same wattage as the Kaze but feels about 10-15% stronger. Prices are super cheap compare to Kaze and these are good for 90% of the purpose needs for sure. If you're interested Ping Hawkfish007
Finksy Fan
Finsy / Taylor send me some of these to play with. They are absolutely beast! OMG!!!! They are a little more wattage and louder at startup but it's a nice sound unlike the screetching Antminer fan sounds. These definitely can cool S7 and S9 with ease. They will also be great for the IBM server PSU. They are louder so best to use in garage or hosting facilty but again it's a nice loud white noise sound not nasty Screetching sound. It's the sound of "FEEL MY POWER!!!" I'll let the picture speak for itself. The white material is the TARP I use for my portable wall. Notice how it becomes a Sail when hit with 3 of these Fans?
You simply can't go wrong with either of these fans. They are so awesome, wish I found them back in the S7 days.

Niceeeeeee.
Yeah nothing beat a clean looking install, nothing more satisfying
Lol, i can't imagine the looks on you when electricity goes out
But you seems to have been pretty careful so i highly doubt it's your fault, now to explain it, that's another matter
Those PSU's look awesome, what are their specs/price/model ?

Sounds like you have a wonderful setup! Dual power would be a dream as every time my neighborhood lose power, my wife and kids give me the dirty looks like it's my fault. My neighbors look at me like I'm draining the town of all power.

I really love my IBM 4KW server PSU bundle for it's low cost per GPU powering option if you're powering 2 or more rigs. It's also very compact and very quiet when used with recommended fans which I will discussed shortly. I wouldn't run it inside an office but you won't hear these when box fan are running unlike the 2880W server PSU fans which are screetchingly loud.
I love the fact that I can power up to 5 x RX470/480 rigs very cheaply and efficiently. These are beasty PSUs and I've ran them in my garage in 115F temps with no issues provided that you pair them with good fans. They do have thermal shutdown protection to prevent failures and issues. I've used the same server PSU carried over from the S7 mining so durability is fantastic as I've very abusive and rarely run them below 75%. I've actually ran them close to REDline most of the time with the 3 x S7 OC which is over 4200W. So I guess with the GPUs and the help of the baby ATX PSU, I'm finally letting it work less as hard. =)
Example of 8 rigs powered by 2 x IBM 4KW server PSU Bundle. I used to have them power 10 rigs but I figured for the shed I want to keep simple, plus the Fury rigs eats up double the PCI connections. If you're interested in these, you can contact Finksy, he's very well known on the forum is also a great wealth of information regardless of whether you buy from him or not.
The cabling is so sexy and so fresh and clean......clean. =)
The server PSU cable are 6 pins to 6 pins but you can buy 6 pin to 6+2 pins or in my case use 6pin to 8 pin adapters for my old legacy 6 to 6pin cables.

Can't agree more with you, i feared network/internet outage alot.
I use pro-grade netgear switch cascaded with a dual copper/optic fiber ring trunk allowing 4 level of redundancy (network, switch, media, port), and for internet connection i have a quad aggregation with 2x DSL lines, one satellite line, and one 4G lines, the 2 DSL lines are aggregated and supply the normal internet, in case of failure i can fallback to the sat one, and in case this fail the 4G one. The 2x aggregation box are custom made and use a licenced custom OS from OVH to run it (useful to get the custom static IP, i could have done it open-source otherwise but it's the same cost with or without the custom OS ^^) so far never had to fallback to sat or 4g, but as we say, better safe than sorry
for power redundancy i have 2x separate electrical supply lines (pro line and home line) if i have any trouble with the pro-line i will switch to the home line for powering the rigs, even if the electricity cost twice more on the normal line, it's best to not lose mining time
so far i had maybe a 2h switch on the home line in the last 6 months so it's not bad. Im still a noob miner, but learning everyday.
Thanks to show us how years of experience speaks for themselves

My Network
Dual Internet - DSL via Consolidated Communication and Comcast for Cable Modem. The cost of any internet outage is very costly and sometime can cost more than few months if not the entire year of Internet service so I figure it's best to have redundancy. I have redundant ethernet connection from the shed to the DSL and cable modem and likewise for the Garage and my office. Doesn't really help when I lose power though, haven't solved that issue yet. =)
I'm very fortunate that my good friend and local miner Lac gave me these Enterprise class Rack mounted switches. They are awesome! No more cheap Linksys junks.
