VERY INTERESTING!  Do you have more information on it?  CFM?  Circumfrence?

I am trying to use this to blow out the hot air in my warehouse.

I have tried many different positions but the temps seems unchanged

I may doing this wrong way or wrong placement

Anybody has seen this in action?

In the future, we might only need 1000W PSU to drive 6 cards as they are more efficient and use less energy,

 I standardised on Seasonic for the most part a long time ago, but have had good luck with the very few EVGA and SlverStone gold units I've used.
 Have had exactly *1* failure on an X-series Seasonic - which was replaced by NewEgg very promptly under warrenttee no hassles.
 That unit died when I accidentially pulled the power cord out while it was running 1.5 Antminer S5s, so not entirely it's fault.


 Why buy a Rosewill power supply from anyone but NewEgg?
 That's NewEgg's in-house brand / subsidiary and they should be able to sell it for less than anyone else.



 I finally bit the bullet and bought my first pair of RX series cards - Sapphire RX 470 blower-type (not sure if they're reference or just blower-style).
 They'll likely end up as a 2-card rig for now though, after I shift a couple of HD-series cards to singleton Semperon-based rigs.


 One of these days I need to go through my rigs based on older MBs and rationalise stuff - I'm finding that the NiceHash ZEC miner works well with the NVidia cards I have but does NOT play nice in mixed rigs unless the only "mix" is a single APU....

im interested in one of those or maybe something close. the 4 card rig will be a test run for my new htpc matx build

Awesome Phil! I really appreciate that!!  I have a few ribbon risers around but none are of the x16 variety, so that will be a perfect "surprise" 

I will send a 16x ribbon riser as the surprise. I am shipping GabryRox the molex cables.
  and I have a 16 pin riser.  I am going to use the  plat 1200 watt quark for my r4 coming on weds so it needs only have pcie cables and the mobo cable.

I have run into this problem with the 16x slot not working with a usb riser in the past with other motherboards.  I think it may be the motherboard.  I would try a ribbon riser in this slot to see if it works...if you have a 16x ribbon riser.  I now exclusively use the MSI Z97 Gaming 5 motherboard with usb risers and do not have any problems. 

Hey Aries... yeah, that is the exact one i am using for my 2nd rig (6-GPU hopefully).  I have the 1000W version powering my first 4-card rig and really liked it, except for the fact that both are short of molex power cables (if you are using powered risers, that is).  I think it's not a problem for you because I believe I remember that your builds used the ribbon type risers.  Lucky for me that Phil has a couple extra that I just bought from him, so I should be up to 5 GPUs on this rig after they arrive.

Happy to report that I got my 2nd rig up and running last night!  Currently running 2 MSI 470s mining ZEC at about 165 S/s each straight out of the box.

The only issue I had so far is that I initially tried to plug the 2nd GPU into PCIe slot #2 (the x16 slot on the ASRock BTC Pro Mobo).  For some reason, this didn't work. Couldn't even make it to post.  When i tried the exact same in slot #3 (x1), it worked fine.  

So, my question is this:  do i need 1) a different riser for this slot? or 2) do i need to do something in the bios to make this work with the powered x1 USB riser?

I did not - but think it should be quite straight forward

Here is a 1200W Platinum PSU that works good for me!  It is a powerful PSU in a small package:  7.09 x 5.91 x 3.39 inches

sorry for off topic, but do someone have a link to download a Bios mod for Sapphire RX470 4GB Nitro ?

Edit : found this one : https://forum.ethereum.org/discussion/9533/28mh-470oc-nitro-4gb-boysie-rom-dual-mining
I'm about to check

If anybody need, I have the link to the mod for Rx470 4GB reference style. But looking for nitro one this time.

My farm standardized on EVGA 1000-G2, 1300-G2 and 1600-G2.

Can't afford Platinum EVGAs - well I can, but the budget doesn't allow it and its not necessary for mining.

G2s are reliable enough anyways.

Have any tried their 10-year warranty?

I have 2 x 1300w that seems dead after a few days of use.

I have used the OCZ gold 1250W. It is good. I also use the Corsair 1200W with the power usage monitoring.

Good to know thanks. I will highly consider them for my next build.  I just hate getting everything ready to go and then being short on power cables.  Granted, I could have checked it any time in the last 3 weeks but was just too lazy. But still, you would think that these higher end PSUs would have more than enough cables, so I will check out EVGA next time.

Historically I used only EVGA Gold. It always enough of power cords for everything

Thanks Phil. PM sent.  Once again, you are the best

You are lucky I just got a 1200 watt quark delivered on Saturday.
So I can send you just what you need. Shoot me a pm

So, I am most of the way through my 2nd mining rig build but when I popped open my power supply to hook up the cables, I realized that I will yet again be short on the molex cables    This happened on my first build since my x99 mobo required a molex for added PCIe power, putting me one 2-molex connector cable short. Luckily, Phil came to the rescue as he had an extra one from the same 1000W Rosewill Quark series Plat PSU.

This time around, I went with the Quark 1200W since I want to power 6 GPUs off an ASRock H81 Pro BTC Mobo.  I also thought i read that this PSU had more molex connectors but alas, it only has 4 on 2 cables     Assuming this Mobo will also require extra molex power for more than 2 GPUs, this means I will only be able to hook up 2 of the 5 GPUs I currently have until I am able to secure 2 more 2-molex cables.  The bad thing is, it seems that since this is a full modular PSU, only cables from this brand and series will work with this PSU, and I cannot find them available anywhere online, including at the Rosewill store.

So, I would like to ask if anyone might have 1 or 2 extra of these laying around they would be willing to part with. I will of course be happy to pay a fair price in BTC.  Also, if anyone knows where these might be available online, I would appreciate the tip.  Thanks!

I switch between ETH and ZCASH pools with Ethman.exe easily...... copy the right config.txt and epool.txt to all rigs with a single click. And reboot / restart all rigs also with a few clicks. How easy is that..... saved me setting up a proxy server and loose control the rig names etc.
