By the looks of it sounds like it's going to be an absolutely earshatteringly loud psu. I don't know for sure but three front fans and being from delta doesn't help much.

This will be a very loud PSU. Those small fans spin at 15000rpm or more and make a ton of high pitched noise

[philipma1957]

and  it won't be platinum  as the plat rating is made  without the fans.

those fans will pull  25 watts each.  and that is 75 watts
 which is 3%   so it will be more like 90 or 91  not 94

I know this from the   ibm 2980  which pulls around 70 watts for the fans.

I was able to mod them and use optimizer's  boards   the fans I used pulled 30 watts and were quieter.


I run 2 avalon 721's or 2 s9's  forgot  which is which

could you link the replacement fans

and ty everyone else i get that feeling to very loud but couldn't turn down a brand new 2400 w psu for 44 $ free shipping, i have two of a X Adapter Rev:6, I was told should run it ,, there not to bad..http://www.ebay.com/itm/371667776770?_trksid=p2060353.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT

3 of these  use half the power and are not as loud.  but  i use 2200 of 2980 watts on the ibm 2980's

if you use 2200 of 2400 watts on the psu in your link I don't know if these will work.

Funny, I ordered one of those also to check out - there's another forum member selling one with screwdowns in the marketplace.  He said that the fans are thermally controlled, so if that's the case then it might be a good option - but as others have said, those small fans are brutally loud.  I used those same IBM PSU's, and I ended up modding them to use a single thermally controlled 120mm fan which made them MUCH more pleasurable to use.  2400w gives a ton of headroom for my applications, so I'm hoping they're run pretty cool on their own - but keep in mind that PSU's have an efficiency curve, so if you're using too much or too little power, you'll stand to loose a couple % of efficiency.

wow this PSU  is all most not heard all i hear is the A6 fan and my A6 is running  @ 3.4 th @ 420 or so , if I set it to 500 it actually hashes like it should and the Voltage actually holds at 12.1/2 ...
The PSU is brand new , or smells and feel that way ... so for 44 bucks you can't beat it ..the full kit on Ebay sells for 107 with the X Adapter Rev:5 I'm using version 6 link is below..

two of these can power it http://holybitcoin.com/product/gekkoscience-dual-purpose-dps800-dps1200hp-common-slot-breakout-board/ with out issue

two of these without problems http://holybitcoin.com/product/hp-1200-watt-common-slot-psu-bundle/ or  J4bberwock  Breakout Board for the 1200 watt psu

two of these http://www.ebay.com/itm/371667776770?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

it's amazing how quite it is ...


I'm actually afraid to leave it at 500 now because it hashes @ 4.2 th @ 12.2 volts according to the software Avalon supply's and the fan spins at max speed, it over heats to much for me .. so I leave it just below 450 that seems to be the best all around for temps and speed ...

I was gonna sell the A6 i don't think i will now ...I'll post a Screen shot after it hashes two hours i want see if it holds up ..

over all best thing i bought in a while or some thing that is worth the money .....

Hi,

Having a couple issues with these power supplies.

I have a three phase 200amp services and I am trying to run 12 Avalon 741. When I have all of them running I have lights flickering. In my calculations I have plenty of room and I don't understand why I am running into issues.

Any input or suggestions would be greatly appreciated.

Thanks

Why do folks always leave out giving us at least *some* details other than 'it doesn't work...'  
Ya know, things like what kind of 3-phase? Delta, Wye, Wild-leg (one phase center tap'ed for 120v)?
What is phase-to-phase voltage?
Are the miners reasonably balanced across the phases?
etc.
