Update Large review of Finksy/J4bbrwock server psus compared to ATXpsu-photos up

[kilo17]

I started out with a couple of NMB fans (great fans) and a piece of Duraplex that cost $10 at Lowes.





I cut out the fan holes and then I used a hot glue gun to anchor it in place. (I also used the hot glue to seal up the holes)





And BAM, a nice quiet and cool pair of 2880's

[kilo17]

Then I took 3 2000's and attached a 180mm fan on each side in a "push/pull" config.

Like what you have going on there, Kilo! 

THAT should get the job of cooling done for sure.

They are great fans and put out good air flow.

I've had good luck with NMB fans lasting a long time, not high-performance high-flow like Delta high-end fans but good for what they DO do.
Quite a few of my older computers have 80mm or 92mm NMBs in them (most bought used, unknown how old, yet they still last years).

[philipma1957]

A big key to either kilo's mod or my mod is as follows

my new fans use 25 watts do the job of cooling for 1 2980 or 1 2880 stock oem fans use 60 watts

so my mod drops 20 db and 35 watts

35 x 24 x 30 = 25 kwatts per month or around 2.50 usd a month


kilo17 mod uses    25 watts  for 2x 2980's or 2x 2880's

stock would be 120 watts  so a 95 watt savings 95 watts a month =

95 x 24 x 30  = 68 kwatts per month or around 7 usd a month

I will add my white fan to  my dual 2000/4000 psu.

some time next week  I will demo a really good fan control for these mods

sound level in my basement/den/HT running 2 ½ avalon6's  using the dual 2000/4000 watts  psu with breakout boards




units are in the garage



room for three more units




i turned the 2980 on and the noise level in my den is 38db.

Nice work kilo!  I noticed that the 92mm fans have 4 wires though.  Do you only need to connect two of those 4 wires to power them up?

Yes only 2 wires were needed.

What do you think about Corsair HX1000i compared to the one mentioned in op?

It also works on 240 volt, and more importantly it possesses that silence mechanism of its fan.

What do you guys recommend still?

I'm trying to move away from ATX PSUs and going with server PSUs.  Not all server PSUs are super loud like the IBM 2880/2980 and other have their own fan unlike the DPS-2000BB.  There are breakout boards for many of the HP PSUs as well as for the Dell 750 PSU but those aren't powerful enough on their own to run a S7.  I believe the highest HP PSU with a breakout board is 1200 watts on 208-220v and they don't have as many PCIe connectors that the 2880/2980 and DPS-2000BB have.  If you have 240v and you plan on running multiple S7 or Avalon 6 I would recommend the DPS-2000BB.  The Corsair is expensive and you can't run an S7 off that.  I guess it comes down to what you plan to run with it and how much do you plan on growing.  The only advantage in my eyes for an ATX PSU is that if you ever stop mining you could probably use the PSU to build a PC.

The corsair hx1000i is costly 170 to 200 for 1 unit  and  1 wont have enough power for the avalon6 or the antminer s-7

server psu's here with the fans recommended are far quieter then the s-7.

So a quiet expensive atx psu to run the s-7 does not make a lot of sense. you would spend about  3 x 180 to get 3  hx1000i's

they would run 2 s-7's  

the dual 2000/4000 would be able to run 3 s-7's  and cost less.


in both cases the s-7's would be louder then the psu's

but if you want to run an atx with the avalon6 try the evga 1300 g2

it has power enough to run an avalon6 and is pretty quiet.

I am not anti atx but they are not so good for the newer power hungry asic machines.

So I ordered a pair of DPS-2000BB from a server supply company and I finally got them yesterday.  They sent me two Rev. 3 which I think to myself great under Rev. 9 so it should be good for the volt mod and all that fun stuff.  Unfortunately when I plug the breakout board to the pair of PSU and connect the power cable I get absolutely nothing.  I take the exact same setup, same power cord, same outlet and same breakout board and plug it into a pair of Rev S8M and it works perfectly.  Has anybody else had any experiences with Rev 3?  I could understand if one of the power supplies was dead, but neither of these power supplies powered on at all.

I believe I never got an older revision than s5 or s6. To try them individually, you can plug the bottom one to the dual breakout hoard. This way, even voltage adjust works with a single PSU.
The pinout for the PSU have to be the same on all revisions, or you'll have trouble on the servers. If the breakout board works with one revision, it'll work on all unless the very old revisions are using another pin combined with the one I use to turn on the PSU.
Or you may have 1 or 2 dead PSUs.

Thanks J4bberwock.  Neither PSU turned on for me.  I'll try them individually next chance I get which probably won't be until Monday or so.

I just noticed that yours is a DPS2000BB B all of mine are DPS2000BB A

I'll try to find a cheap BB B locally to test.
The only ones I could find with a quick search were 200€ ($220) each.

Edit:

INTEL-ABCEPSU20-2000-WATT-INTERNAL-POWER-SUPPLY-DPS-2000BB-B

It's not made for IBM, so it's very likely that the pinout to turn it on is different on this one.

Thanks J4bberwock.  I'll have to be sure to get the right ones.  I didn't even think that would matter and especially since the breakout board still fit perfectly.  Oh well lesson learned!  Going to try to return these.

mine are rev 7 and 8 both have an A at the end

Huh, had no idea Delta made these for Intel as well.

Yes, that's quite strange they used the exact same PSU and connector but not pin to pin compatible for 2 companies.
