Topic: Update Large review of Finksy/J4bbrwock server psus compared to ATXpsu-photos up - page 16. (Read 20897 times)

Ingenuity at it's finest, Phil. Good work. 

those white cutting boards are really rugged and tough.  Pretty thin  material.

What I like and did not show is the psu can sit right on top of  2 or 3 avalon sixes.

A pretty neat compact setup for the guy or girl that went all avalon six.

Nice job on the fan mount!  Brilliant.

Great idea!!!

Nice work, Phillip

Thanks Phillip.  Got your tracking #, can't wait to test it out.  My C19-C20 cable came today so I was able to fire up the 2K IBM PSU.  I'm just using 1 PSU at the moment since only 1 S7 is using it and waiting for the mount.  Without the Voltage changing feature, the S7 hash rate is the same on this PSU as on the EVGA.  Also since I have the older boards, I only have 24 PCI connection max when using 2 x IBM 2K PSU which means I can only connect to 2 S7 and 1 Avalon not 3 S7 like the new board.  Needless to say, I'm anxiously awaiting for the new boards.  =) Here are the picture of my temporary setup so DMwardjr can get a visual of the size of these PSU.  They are quite compact and the Ultra Kaze fan push a ton of air without being too loud.  I can only hear the S7 fans not the Ultra Kaze when both are on.  Very happy and appreciative of this PSU recommendation from both Phillip and DMwardjr.  I have 2 more S7 coming next week as well as additional IBM PSU.  Will update once I have the FAN mount from Phillip.

I mailed it out to you.  I have many more photos.  It all fits in a padded flat rate envelope

fans are outside mount  holes not cut



fans are inside mount holes not cut


same as above.  you do not need to do this push pull if you use the 38mm scythe fans they will cool the 2x psu's off even when doing 17 amps or 4080 watts.
So you can mount 1 set of fans.  this mount system cost me under 3 bucks.  I used all parts in the home. I did need to buy a cheap replacement cutting board so the wife stays happy!



proper hole saw size is 4 inches  for a 120mm fan


cutting holes


two holes cut ready to assemble


two fans on inside mount



fan is mounted inside note only 1 screw is holding base to mount I have provided 3 screws.






the base has an aluminum plate to protect the wood under it
fans are not supposed to be on both sides this is just to show you can do either side of the mounting plate


3 long screws with washer attach the plate to the base.
and of course you would mount the fans on one side not both I did that to show you have a choice of sides




breaks down and fits in a flat rate padded envelope

AWESOME WORK!  This will be perfect for what I need.

I did a mount system for nhando.

the clear plastic j4bbrwock /finksy mount plate is set over a  cutting board from a dollar store




x marks where I use a hole saw and you can see the nylon screws with black nuts that will hold 2 fans down the road





A 120mm fan



two fans mounted




a shot of the base.  note rubber feet will cut vibration down.




mounting plate with fans and it is attached to the base


here is finksy/j4bbrwock on the right and my mount is on the left

note this is fan overkill  as the 38mm are good engouh to keep psu cool at 4000watts

i think the 2880watter is good if you do not have a sound issue.

i would not want to do five of them if i had to sound proof them.

i came up with a plan to mount fans   for the 2000 watt psus  send me a pm i will mail a kit to you if you are usa based.

You da man, thanks Phillip.  PM sent.  Will post those picture on my Garage / Shed build out thread

Sounds like a plan. 

Look forward to some photos soon.

Thanks for sharing ideas.

No Batteries.  New Jersey buys back power.

 So if you have a 60k plant it works out to about 20k  24/7  'free' power

So while the 60k plant seems large only 20k would free once you pay off the panels.

But since there are no batteries the system is much cheaper to setup.  It also does not break or need much maintenance and panels have 25 year warranty.

This will be a ground install on a 2 acre piece of land. Ground installs are very easy to fix since panels are low not on a roof.  You need land.

The guy I am working  with is on this forum and will do a reveal when we are closer to setup.
I may take a few photos of the site. Post them in a bit.

Wow, you will have it "going on" with the solar.  Did you make the panels yourself?  I know as thorough as you are, you probably experimented quite a bit already with one rig on solar over a period of time.  I'm curious, are you going with double the size on battery banks than normal just in case you have a couple of days with very little quality sunlight?

Yes, I love the features available for the 2 x 2000 BB PSU's J4bberwock put together.  Unfortunately, it's too much of a pain to do the same with the 2880's.

I have yet to purchase 2 x 2000 BB.  I have the B/O Board, etc... but have not bought the PSU's yet.  Could you tell me if the 2000's are the same thickness as the 2880's?  If so, I might double stack the 2880's to have them the same thickness as the 2 x 2000's before placing the wire shelves on top of the PSU's before putting the rigs on top of them.

very nice setup.

for my garage four to five kwatts

one 2880watt and one four thousand watt dual psu will be enough.

i have one 30 amp circuit .

when i setup the 60kwatt solar with a forum member.

i think we will go with the four kwatt boards.  they are quiet and the three power settings  are really nice

Yes, they are good PSU's.  I've thoroughly enjoyed mine.  Especially, for the cost benefit compared to the Corsair PSU's I first purchased when mining.  Thanks for all the info you've provided.

Sound is not much of an issue to me at all.  Everything is downstairs behind closed french doors.  I have 18 x IBM 2880's total.  I have plans to buy more 2880's and the J4bberwock breakout boards very soon.  I've figured out a way to have a cleaner look with 6 shelves on a 6.5 feet wide rack with 12 x S7's and 6 x IBM 2880's on each shelf.

The main reason I like the 2880's is the way they can be used to easily stack rigs on top of them.  The same thing could be done with the 2000 BB PSU's but each shelf would have to be higher above the other.  I will explain below:

Please ignore the current remodel of my home.  I have one more coat of paint to put on the wall after spackling and sanding a couple of spots.  I also have to fill in the finish nail holes with putty then sand those before painting them.  I thought I would share this with some who might need an idea.

You see 6 x IBM 2880's underneath this "wired" closet shelf?  One of the 2880's is taken out of it's anti-static protective packaging.  I left the others in their packaging for now.



Here is a close up view to show you there is plenty of space open to allow the fans on the 2880's to breath while also resting S7's on top of the 2880's.  So, the 2880's would rest on the wire shelves of my racks while the S7's will rest on top of the wire shelves I have on top of the 2880's



Here is the wire rack I was referring to:

The rack in its present configuration will be changed to do what I want to do next with laying the 2880's flat on top of each shelf.

I would set the 2880's on the wire rack [spaced appropriately]; then place the wire shelf on top of the 2880's; then place S7's on top of the wire shelf that is resting on top of the 2880's.

Each S7 is approximately 4.85 inches wide.  The wire shelf resting on the 2880's is 72 inches wide.  That 72 inches is plenty to put 12 x S7's on top of 6 x 2880's.

i think the 2880watter is good if you do not have a sound issue.

i would not want to do five of them if i had to sound proof them.

Seems like a lot of work and add more cost / real estate space when noise is a concern with the 2880W PSU.   I want to thank you for the recommendation on going for the 2 x 2K PSU instead.   The 2X2K IBM PSU have a much smaller foot print and noise is fully controllable based on the fan chosen.


P.S  The fan you recommended just arrived.  I don't have any brackets for these PSU.  Would those Tape you recommend be sufficient to mount these FANs.  I have that on order as well and it should be here by Wednesday.  The individual 2K board makes it much harder to combine the PSU then with the newer board you got.   Can't wait for Finksy to release the new board to the public.  I'm definitely in line to get 1.  Really love the hashing results you been publishing.  It definitely justify the cost for me upgrade to 220V outlets.

No they are not fire resistant but I have a fire proof pad on order and will add it and photo it for everyone

I have used the material above and it is fire resistant on the foil side

 Phil are those materials fire resistant?

Yes it is from a twin sized foam mattress top

 I used a six foot wooden board cut to 36 inch lengths.
I attached the boards to both sides of the psu with double sided 3m foam tape.

under the psu are 3 layers  2 rugs the the egg crate foam

over the psu is a rug

see the 36 inch wooden boards the egg crate foam and a  pair of rugs under it. actually of the rugs is rubber standing pad.



and here is a rubber stand pad over it  the air flow of the fans is full speed with out restrictions


another look at this top standing pad

It looks like you used a mattress topper that foam looks like egg crate foam from a mattress topper.
