Please see here for IBM 2880W PSU Packages: https://bitcointalk.org/index.php?topic=966135

Please note, at this time I am unable to source dependable DPS-2000BB PSU's.  I can sell breakout boards and packages without PSU's, but until the market gets more units available I can't rely on having them available when orders are placed.

Please see here for GPU rig powering packages with all adapters necessary to run rigs off these PSU's!  https://bitcointalk.org/index.php?topic=1864539 (https://bitcointalk.org/index.php?topic=1864539)

LEASING CONTRACTS

I have started to offer leasing packages for use in approved Data Centre/Co-locations.  This can be beneficial for many reasons:

-Less upfront capital required, allowing more to be spent on additional mining hardware which can offset much or all of the cost of the lease

-Limits risk and cost of equipment failure, and associated down time due to failures

-Saves shipping costs for heavy PSU's to and from hosting location for duration of your contract

-No equipment depreciation

-Helps eliminate ownership problems associated with Group Buys, when more than 1 member shares purchase price of PSU to host together

-All maintenance, replacement, shipping, setup, and lost revenue from down-time due to PSU failure is my responsibility

Please contact me for details.

Shipping prices will be estimated as follows:

CANADA
1-10 boards -$10
11-20 boards  -$15

USA
Shipping with tracking (from Canada)

1-3 boards     -$15
4-7 boards     -$20  
8-20 boards   -$25  
Insurance is additional, and is tied to shipment value.

Shipping for orders with Cables, PDU's or PSU's will be calculated individually, to make sure you are getting the best rate.  All prices are in USD. I am willing to accept escrow through OGNasty, and can also do Paypal but buyer will be responsible for covering costs of either services (4% added to paypal, OG charges 1% for escrow).

Each package of PSU, breakout board & 10x PCI cables is approximately 16 lbs.  Shipping to most of USA is approximately $30 for 15 Lbs, $50 for 30 Lbs, $65 for 45 lbs

The BTC address for all non-escrow breakout board orders is here: 1GWQYCv22cAikgTgT1zFuAmsJ9fFqq9TXf
I will not PM you asking for payments to any other address, so beware of F1nksy, Fink5y, or whatever scammy names might pop up.   ;)

Good stuff! payment sent for 2 boards w/ adj. voltmeters  :)

Definitely interested.  Will PM you for more details.

I did a long review on finsky/j4bberwock   2x 2000 psu's


Frankly I like them better then the 2880watt  mostly because they are in my garage and they are a lot quieter.

They come with the 30 pcie jack break out board  so 3 s-7's or 4 avalon sixes.   I will post a link to the review.

https://bitcointalk.org/index.php?topic=1284563.0;all

the 2x 2000 psu package is giving my 17 amps x 240 volts = 4080 watts running 2 avalon sixes and 1 s-7  with really good numbers

Ordered a package today.   Money sent FINKSY.  This board is sweet, also will be wanting some FAN mounts when they're available.  I'm sure I'll be back for more of these boards.  Will there be an option to change the voltage for the 2980 PSU in the future?

No, unfortunately J4bberwock has mentioned that voltage control is not possible on the 2880/2980W IBM PSU's.  PM'd you back, thank you

Can we see a picture of this setup? :)

Very nice! May I ask why the older revision PSUs fetch a slightly higher price?

At this time I am finding them harder to source with certainty (that they are older revision), whereas the non-voltage-adjustable units can use any of the DPS-2000BB PSU.

Can't wait until you get the side plates done.  Is it better to have the fans push air into the PSU or pull air out?  I assume a push/pull setup with 4 fans would be overkill and you would only need one side plate per 4k psu pair.

I have my 2 FANs sitting at the bottom pushing air up and it's sufficient.  2 x Ultra KAZA fans for $35 on Amazon.  No need to waste an extra $35 on more fans.  Pushing air side ways was ok too.  These fans are quiet and can do 3K RPM.  You won't hear them while the S7 is running.    Please see Phillip's post for the detail different layouts and pics.

https://bitcointalk.org/index.php?topic=1284563.new#new

Thanks nhando.  I read his post and saw your pictures.  Just waiting for finsky to get the side plates in stock now.

Finksy can you tell us which revision we need to look for ?

thanks

I believe that those are harder to find and those are the ones that you can modify the voltage.

Any word on the side plates yet?

My bad i quoted the wrong question !

/fixed

I could be wrong but from what I remember you need S8 or below.  Somebody please correct me if I am wrong.

Edit see here: https://bitcointalk.org/index.php?topic=1178099.msg13061344#msg13061344 (https://bitcointalk.org/index.php?topic=1178099.msg13061344#msg13061344)

Yes, S8 or below if you want to use the external voltage adjust.
DPS2500BB will not work for voltage adjust.

If you don't need voltage adjust, any revision will be fine.

Merci :) (Thanks)

Finksy,

You got PM for more orders. 

P.S Are the FAN mounts ready for selling yet?

Anyone hear from Finksy at all?  Wonder if he's on vacation or just super busy.

Yes, sorry just been super busy with work, not able to spend time on here.  Thanks J4bber for chiming in, I am soon to receive a large order of DPS-2000's, and I'm hoping all/most of them are early revision which case if they are I'll be able to drop the price on them.  Thanks, replying to PM's now (and for the next 2 hours)

STILL no firm ETA on the sideplates, I am at the mercy of a local machinist now.  They are being made out of sheetmetal, and will update as soon as I can with pricing etc.  I am still hoping to match J4bberwock's price on the sideplates.  Also, my 24"PCIe cables as well as C19-C20 cables will be arriving sometime late this week or early next week, then packages can resume sale.

PM sent !

Anyone know if these IBM PSU will automatically shutdown at certain temperature threshold?  Just preparing for the summer especially since power 3 x S7 Batch 8/9 will be maxing these PSU at 100% load.  Want to make sure there's some extra safety built into these PSU like how the Antminer have auto shutdown at 80C

I know the 2880's and the 2980's do.  It may be the 2000 BB's do as well.  However, I've never had the 2000 BB's.  So, I cannot say for certain.

You have headroom to spare, 3 S7's is like 3630 and those PSU's can handle 2000+ each with adequate cooling. 

Not sure Kilo,  when I was testing via the EVGA which connects the S7 to my 120V outlet to my Wemo Insight, it was showing pulling 1540W at the wall.  I would assume the EVGA G2 1300W efficiency rating is similar to the IBM PSU or worst as the 2KW PSU is not Platinum.    So if I use 1540 x 90% which I doubt the IBM PSU is that efficient = 1386W x 3 =4158W.  Seems overloaded to me but I don't have any tools to measure wattage for my 240V line.

Also I think your math above may be off by 1 digit perhaps typo or close key, but 1290W at 93% efficiency from Bitmain info x 3 S7 is 3870W.  These PSU are no where near 93% and even if they can get 90% they're at 100% load.  I think people are saying these are somewhere in the high 80s range efficiency right?  That would make it way over.  I'm running them now and the garage is plenty cold so it's not an issue right now, but concern when spring / summer hits.

That is odd, i ran my S7 B8 on two EVGA gold efficiency and i was getting 1440W, i dont think a 1% efficiency edge could possibly account for the difference. And with P2 PSU, i get 1415 at the wall with fan at 3400RPM.

The fans are in the 30-36 Watts range each (60-72Watts total).  I don't know for sure, just assuming based on similar fans I am using as replacement.  My fans are running at 4040/4440  so it's using a little more juice then yours.  It's also connected to a power strip via a long power cord 15 ft which I'm sure doesn't help the efficiency.    Forgot to mention a Raspberry PI controller for the Avalon attached to it too but that's probably very tiny wattage.    Also not sure how accurate Wemo Insight is either.  In any event if we simply just use Bitmain's 1290W at 93% rating and not even bother with the guess work from my Wemo insight.   We can see at lower than 90% efficiency for these IBM PSU, we're rocking the 4KW at 100% load or higher with 3 S7 running at 700M.  I'm actually doing it at 731M for stress test now while the weather is cold to see how hot it will get and whether I do have some head room.   I'm going to standardize my next 20 S7 deployment with this exact configuration so I want to make sure it will work without killing the PSU or overheating them too badly that it won't work in the spring.  

Remember though it's 1293W +10% at the wall, or 1422W at the wall given 93% efficiency, which would correlate to their new 0.29W/G rating atw.  This gives us 1,322W DC draw using their ratings.  With 3x on the 4K setup that is 3,967W before fans, so you are over 100% load unless you under-clock.  

Let us know how they make out with your stress test Nhando, I'd love to see if they have as good of over-load/thermal protection as the 2880W PSU's.

Been running the 3 x S7 at 731M on this 4K bundle at 12.2V for the past 16hrs without any issues although the Ambient temperature outside is 50F and my garage is at 72F, the PSU is still a little warm to the touch.  I don't have any box fans running in the back as the temperature is still cold, this is cool using only the Ultra KAZE fans.  The S7s are running at very cool temperature of 55-62 range.  I'll probably do this test for the next few weeks.  If it can maintain at this load, it would give me more comfort dropping their Freq for the Spring / Summer to reduce the load.  So far everything is hashing away nicely at 4850-4900GH.    

P.S It's winter so I'm not running any extra fans and the work to install additional exhaust and cooling are still underway so don't mind the 22 degrees difference, I purposely am using these as winter heaters right now.

You can also open and modify recent revision to connect internal wire to allow voltage adjustment. No need to buy "rare" ones as modification is quite easy.

That is correct, here is J4bberwock's post on modifying them:  https://bitcointalk.org/index.php?topic=1178099.msg13061344#msg13061344

hello i want to buy this

"The "Triple A Package" - $225
Everything required but fans to power 3x Antminer S7's. EDIT: Newer batches (8+) of S7's draw approx. 1300W DC.  Will be running PSU's @ near 100% load, and will require significant cooling.  Reducing load would be recommended for longevity of PSU's.

"

I have adjusted the trim pot to put out 12.5 volts and ran 2 Avalon6 per unit without any issues. ;)

You are correct, I calculated at 1210 (oops), Finsky has corrected me below.  But to clear up, the PSU puts out 2000 watts and the efficiency has to do with the draw at the wall and not how many watts are put out on the 12 volt side.

@Finsky, do all of the revisions have the voltage trim pot on the inside or only the older revisions?  I want to order some more packages but do not necessarily need the trim on the breakout board since it is so easy to adjust on the inside.  thanks

Are the  DPS-2000BB Breakout Adapter Boards in stock yet ?, I just need one board, the US Seller i buy them form is out of stock with no ETA, i Sent J4bberwock a PM , i hope it's no time, he all most never answers any i Send . and HolyBitcoin.com who i buy from of has no Eta for the boards.


nm  J4bber pmed me one is coming this Monday ty



thu :).

Jabber confirmed me that up to Rev10 they have all the internal Pot.

I will be away as of this Friday for a week, and likely unable to answer posts/PM's.  I won't be able to ship any more orders than what I have lined up by the end of the week.  I will resume taking orders when I return around February 1st.   Thanks,

Finksy

Any news about the side plate for the Fans support ?

Are you back Finksy? Sent a pm inquiring about the sideplates.

HerbPean- Here is a link to some useful information I found in my searches to adjust trim pot for my REV1 DPS-2000BB. (From an RC Car forum) From the reading, REV9M and higher require modification before the trim pots on those PSUs can be modified.

http://www.rcgroups.com/forums/showpost.php?p=18117345&postcount=611

They still have the two pots to adjust the Amp and Voltage. You can't just use jabber external control without doing the modification but you can still change the Voltage with the internal pot.

I'm back and will be replying to PM's for the next 6 hours...

Thanks for the link to Kilo's mods.  That is a fantastic solution that doesn't require the early-rev PSU's, and saves me from soldering the damn SMD chips & pots! Very cool and a great solution.  Another clean way to do it would be to use a stepped drill bit until the adjust pot is accessible.

I did the drill thing on the 1200's and takes and extra 2 minutes  ;)

I will do the same ! ;)

Also, all PCIe cables and C19-C20 cables are back in stock (for now, lol. Ordering more now...)  I am working at obtaining some C19 to NEMA variations for a very reasonable price without too large a MOQ.  As soon as I can make it happen I will, PM me if you have preferences (NEMA 5-15P, 6-15P, 5-20P, 6-20P they are all built to handle the same amount of current, but have blades orientated differently to comply w/ code)

Finksy / J4bberwock's 4K bundle is the real deal folks.  So Sexy and So clean clean!  Super quiet and probably easily the best bang for the buck for powering per S7 / Avalon.   I was able to power 3 x S7 OC at 731M for 3 weeks and test it up to 90 degree heat, no issues.  Although I would never recommend OC any box unless you can maintain temperature control in the low 70s.  I have both the Voltage control and non voltage control versions.  I wouldn't recommend pushing voltage too high and it should always be done in a very cool environment or you could risk burning your boards.  Look at how clean the 4K bundle looks with the Ultra Kaze fan.  I can even put it on the side and let the fan push all the hot air toward my hot zones and let it vent out to the attic.  It works well having the fan push sideways or upward, see pictures.

Please be aware!!! There is someone trying to impersonate me: https://bitcointalk.org/index.php?action=trust;u=769932

Please leave neg-rep.  I will get a real price together for you later on this evening alo.

Pm'ed sent for an order.

i also forgot to ask you if you found a source yet for fans

A very frustrating and long-awaited dead end for the side panels.  Machinist backed out, I am now actively looking for a sheetmetal fabricator with laser-cutting or water cutting equipment.  PM me if you have any leads in North America.

I just ended up using a bunch of zip ties to strap the fan to the side of the two power supplies.  They shift and wiggle a bit, but as long as I don't touch them or move them around too much they're fine.

I think Prelude had mentionned to PM him about it.

I may be able to help.  PM me if you have no one else.

-Optim

order placed and payment sent

Just ran out of stock of 24" PCIe cables, more on order.  Lead time probably 2 weeks.

Any luck on the side plates? I need a few ASAP.

Thanks.

How much are S&H to Serbia?

Thanks

PM'd, you'd be best ordering through J4bberwock in the EU.  Shipping costs outside North America are just not very reasonable from here.

Side plate plans are with a new machinist (from BitcoinTalk) and I hope to get an update on them soon!

I have added pictures, and updated some pricing.  No longer need the extra $5 for early-rev PSU's, I have found a reliable source of either revision at the same price for the time being.  I'm hoping to have the 24" PCIe cables in hand sometime next week, will update.

24" PCIe cables back in stock, packages are all up for sale.

theese packages are well worth buying over the 2880 packages , first one up and running on 277vac power
https://i.imgur.com/WopBfFD.jpg

Have you given up on the sideplates?  I see your last post on Mar 18 hoping for an update soon from your machinist.

i am a machinist myself so maybe me and finsky can get together and make something happen with the sideplates

i used zipties on mine and they hold the fans on perfectly , it is a lil tricky as u have to get the zipties just right if u want the psu to sit perfectly flat so u can stack them though 

sideplates have been finalized, just waiting for production and shipping at this time.  I'll have the details of getting the initial batch out to pre-existing 4K customers in the coming week or so.

Nice work! do you sell only the adapter or you have the 2000W psu to?

u can buy them form finsky as a ready to go package , i.e 2x psus , 1x breakout board , power cables , and pci-e cables all in one shot

I like to order the "Standard 4K Package" with Voltmeter & Early-Rev PSU's please.

Thank You

I also sent you a PM looking to get one of the new voltage adjustable PSU's from you

Pmed!

Edit: Scratch that PM. The S9s are already sold out. :/

Bump, get your PSU setups ready for S9's!  I don't want to mislead anyone with the sideplates, I've been told they are in production.  Part of the holdup this time was me and lack of communication, but I will be organizing a Group Buy for the initial run of sideplates to serve the customers who already have DPS-4K setups running, that way you will receive the boards in the least amount of time possible and for as cheap as possible. Stay tuned^TM

Nice was going to ask you last week if you still had any. All I have left to do is mine your money before I send you a PM for a setup.

Packages in stock and ready to ship within 24H.  I will be gone this weekend so won't be available to answer PM's. B2 & B3 S9's can be powered 3 per DPS-4K with adequate cooling.

Hi Finsky,

Let me know when you got the sideplates Im need to order a few,

Thanks

Alright everybody, the sideplates are now in the final step of production.

I would like to thank sloopy, he is the machinist who has arranged the laser-cutting, machining and finishing of all the plates.  He has been incredibly helpful, professional and dilligent in this matter, with most of the delays due to communication on my side.  It's nice to finally have worked with a professional who got the job done, and I couldn't be more pleased with the outcome.  I had offers from other forum members before and after, and I would like to thank them for their time and offer with this as well. 

Sloopy and I will be arranging a group buy to get the initial run shipped off to those who already have PSU's in their hands in the US. I will be in charge of collecting and arranging orders, and sloopy will be arranging packing and delivery to US customers at a discounted price to make sure everyone gets them in as short a timeframe as possible.  Details to follow, at this point we are only waiting on new nylon clips for mounting the front side of the plates to the PSU, as the ones originally sourced just did not work out the way I expected them to.  After the initial group buy, I will be offering the plates for sale with packages as well as with 2x different Delta fan options.  1x Plate per PSU should be adequate for server fans that flow >160CFM each, if quieter fans are desired without sacrificing full power availability from these PSU's, you may need to arrange the lower-CFM fans in a push-pull arrangement with 2x sideplates.  They will work for either side. These plates are infinitely more durable and easier to mount than the acrylic plates that J4bberwock was initially producing and shipping out, if anyone had the pleasure of trying to put one of those together.  If you looked at them wrong they would crack. 

Final pricing and Group Buy details to come shortly.

You got PM Finksy.  Need more 4K board.  Thanks - Nhan

Bump

are those side plates ready to ship yet? Id love to get mine so I could retire my zip tie mounting system for my fans  ;D

Hi everyone! I'm currently finishing a design of one cone duct for this 4k setup which makes use of only 1x 250 cfm fan (added bonus, less power drawn for fan operation) and keeps the psus cool under heavy load. I would like to know if there's interest at all on these, as i'm mainly doing them for myself but could sell them at a good price.

Could use these FAN mount soon.  Been waiting almost a year for them.  I'm still using ADHESIVE TAPE.   Where are we on this FINKSY?


P.S I can testify that Finksy 4KW Bundle is the real deal.  I use many of them purchased thru him and his partners for both Bitcoin mining and now Ethereum mining.  Finksy, you can contact HolyScot if you need the 6 pin to 8 pin adapter as well as risers that can be supported by your server PSU 6pin cable.  This makes your bundle the ultimate solution for both Bitcoin mining and Ethereum GPU mining.  I'm currently powering over 60 GPUs using combination of a baby ATX PSU for the motherboard and power riser and the 4KW PSU for the GPU themselves, works very well.

Here we go guys! https://bitcointalk.org/index.php?topic=1597163  Here is a Group Buy for the initial run of the DPS-4K sideplates.  They are truly amazing quality, sturdy, and tie everything together perfectly.  Sloopy and I will be running the Group Buy for 2 weeks starting now, in order to give everyone the chance who already has DPS-4K PSU's to get them as quickly and cheaply as possible. Afterwards, I will be offering them for sale individually as well as with the packages, and shipping directly myself from here in Canada.

Anyone in Canada looking for the discounted GB pricing on these plates PM me, I have a small stock of the plates right now and I will ship them from here, with sloopy shipping to the US.

Thank you everyone for your patience.

WOOHOOOOOOOOO!!!  About time!!!  My Tape is falling apart!  hehe.  I'm in for some.

Page 1 appears to indicate you don't have the new sideplates in stock.  Do you, or will you be doing another group buy soon?  I assume you have the boards in stock, I plan to buy some more soon.

CrypR,

Not sure if I PM'd you or not, but I do have the sideplates in stock now, the Group Buy has ended and I can ship them out at any time.  I will also be adding them to packages as well as include fan options.  Need to update my OP very soon with new info.  I don't currently have boards to ship, I'm a little back-ordered at this time.  Send me a PM when you're ready, I'll give you an ETA on board production at that time.

Hi Finksy,

I am interested in the 4KW Triple A package.

Please check PM.

OP updated to now include the price of sideplates and fan mounting hardware with purchase of packages or breakout boards.  If you would like to secure the PSU's and fans yourself, just let me know and the price can be adjusted.

I have 120mmx38mm fans scheduled to arrive in the next 2-3 weeks, slightly higher flowing than the Kaze Ultra Scythe, but should still be tolerable for noise level.  I will update once they arrive, expected price range $12-14 each and 185CFM.

Please excuse me hijacking your thread to ask a question but it does relate to your breakout board and fan sideplate combo.

Im a home miner and sound is a major factor for my mining equipment so the side fans are a great alternative to the whine/howl of the small fans on server psus. Are they temperature controlled or just permenantly 12v full speed fans?

Also are there any small capacity psus that would fit the dual breakout board and fan setup? I don't need a 4kw solution as I cant use that much electricity. Is there a dual 1Kw version, or can you recommend suitable psus that would fit (ideally platinum efficienty rating)?

I'm in the UK if that makes any difference.

Thanks.

My DPS2000BB breakout board with sideplate and 3x 60mm fans will have a low noise level.
You can even use a push/pull configuration with lower RPM fans to make it really quiet.
On both setups (4K or single DPS2000BB), the fans are running full speed all the time.

The question is how many PCI-E plugs do you need?
The single DPS2000BB board only have 12 plugs.
If you need more than 12 PCI-E but only 2000 watts, you can still use a 4k board with a single DPS2000BB (or 2500BB) PSU and the 60mm sideplate.

Bump.  Stand-alone ATX-replacement GPU packages coming in short order! Stay tuned...

So I've got jstew's board + fans otw

I think just I need 2 adjustable psus + cables for 4 A6's

If you could include power cables that go from c19 to normal 15-5r or whatever, I have a grow switch controlling the power, it's fully rated for 220, has its own 50 amp breaker and has 8 x 15-5r(I think) plugs

I can get cables if it's not possible or easy

Let me know what to do

OP updated.  Fans have now arrived, and I have included them in the package price.

Away on Holidays from now until March 3rd! Trying to get everything shipped out before then. Will try to keep in touch, thank you for your patience.

Hi Finksy,

I saw that other package using DPS-2400AB 2400w Platinum 94%, which seems a good alternative to the DPS-2000BB.  Do you have plans to offer a board for that other PSU? Or maybe it is not as good as it seems. What is your opinion about it?

It looks like a good PSU, but it only has 18 pairs of outputs which would only give you 3 full pcie connectors and you would need to install the plugs yourself.  The wires look like 14ga wire so I suspect they are expecting users to only use one pair for each PCIE plug--2 pins per 6 pin plug.  Even this approach would only power a single S7 or S9.  I have seen several S7s catch fire with this approach so I wouldn't recommend it.  At least some versions of the S7 don't have thick enough input power traces to handle this much current on a subset of traces and overheat.  You could probably make a custom breakout wire harness to split the current out to all the pins but that would be a lot of work.  They do mention they are adding a version with 16 pcie plugs which would save some manual labor, however, the issues noted don't go away.

I plan to stick with the DPS-4KWs.

Bump this up, packages shipping out daily. Still have some 40A PDU's in stock for Big Momma packages, they are a fantastic turn-key PSU solution! 

Keep your eyes peeled for GPU-focused packages coming in the next 2 weeks.  4K server PSU's could power up to 4x full 6 or 7 GPU rigs without requiring ATX PSU's! Stay tuned...

was wondering about gpu solutions, i was eyeing the 4k to run the top pcie connectors and have a smaller psu (650w) to run the mobo and pcie risers under the cards. not sure if two power supplies powering the cards top/bottom was a good idea but in theory should work.

I'm running 6pin from a server psu to a gpu on a riser. The riser is powered by the same power supply as the motherboard is connected to. The mobo/cpu is just an old pentium 4 and a 250w psu running windows 7.

It's not the best setup but stuff I had just laying around.

any updates finksy? i want to see what this looks like. i want to make a 10pc rack, 6 cards each. my original idea was to dps2000 power the cards then i have a atx psu for each pc. jstefanop is making a special daughterboard so one system would have 16 gpus but keeps teasing everyone.... waiting for him as well to show it off and price it. the wait is killer!

Finksy

is there any news about PICO's ? as i readed from yun9999's tread you was going to produce some bunch of PICO's and is this true ? :) if yes when they will be available for purchase. at this time i need 1 Deluxe 4K" Package and 4 PICO's...

GPU Packages now live! See thread here: https://bitcointalk.org/index.php?topic=1864539.0

Hey I've sent you two pm regarding "big momma" package.

PM'd back, thanks.

Hi Finksy. I sent a pm regarding breakout boards. Thanks

Sorry to ask this in your thread, but are these for sale in the EU too?

I would also want to know the answer to the question above.

Cheers!

I can ship to the EU, but shipping cables/PSU's is very heavy and VERY expensive from here in Canada.  People have had more success sourcing their own PSU's at least and purchasing the rest from me.  Keep trying to contact J4bberwock as well, he is based out of EU and this is his board design.

You got pm. Thanks

I got 2 "Deluxe 4K" Packages about a month ago and I love them. They were perfect for getting my over-powered APW3+s off of my S7-LNs and freeing them up for my newest batch of S9s.  ;D  8)

Sent you a pm for an order, thanks!

Sent you a PM for an Order, Thanks.

Thanks Finksy, sent you a pm

PM'd as well :)

PM'd you.

I'm currently watching a 6-GPU rig pull 1090w at the wall (248v)... I'm looking to push this to an 8-GPU rig, and then replicate for a total of 3 mobos and 24 GPUs.  If I assume the non-GPU components take 150w per rig, that takes me to approximately 4250w (at the wall). I have external cooling available powered outside of this PSU, so assuming temperatures remain good.  (For example, my GPUs run at 60º +/- 3º all day long.

Do we think one of these DPS-4KW units will safely handle 4250w at the wall, continuously?

OP updated, PM's being replied to as quickly as I can.

DPS-2000BB PSU's are out of stock and unavailable to me at the moment, so PSU packages are only available without PSU's for this time.  I still have many IBM 2880W PSU's in stock, and can use them for GPU packages as well.

To answer your question, 4250W at the wall at a 90% efficiency is only 3825W DC, or 95.6% load.  It is heavy, but with sufficient cooling it can work.  Heavier loads can impact PSU longevity, but unfortunately with these PSU's there doesn't seem to be any consistency in what that load is and if/when they will fail.  I have seen many of these PSU's run at over 100% load for extended period of time with adequate cooling, and I have seen them fail under moderate loads for no reason.

Awesome, and thank you for that insight.  I saw your OP update about PSUs out of stock, and have sourced two separately in anticipation of your return.

Great, thanks for taking the initiative! PM'ing you back now BTW.

PM sent. Still trying to get a rig package bought. Thanks

How would you suggest wiring for one of these beasts at home?

ummm... if you have to ask, then you probably shouldn't (https://www.google.com/search?q=how+to+call+an+electrician)

oh but I should :D

I was thinking about getting a separate pole installed just for 240.

I'm guessing you either didn't click the link or don't get my brand of humor.  :-\

yeah you're probably a quasi generation above me or below me or something.

wait you're a dad aren't you?? ;)

I've had some guys tell me that I was "a real mother...", does that count?  :P

Hi Finksy, sent you PM.  Thank you!

Order components without PSU's for $135

Hi Finsky -- do you still have above package? Can I have 1 order? Let me know and I will send you BTC or paypal

Please note:  I had a very unfortunate incident today in which my commercial space was completely flooded due to the gross negligence of a tenant above me.  Losses are significant, I have spent all day moving my inventory off-site and salvaging what I could.  My time is going to be spent fulfilling existing orders as quickly as I can, but I will not be available to quote new orders (some of the PM's are a week old or more) until later this week when I get myself situated.  I apologize for the inconvenience, and for anyone with outstanding orders please know that I am doing everything in my power to get your orders re-packed from un-damaged stock and will be shipping it out as soon as I am able to.

Oh, thats rough, best of luck on the clean-up and salvage! :/   

i have no problem considering my PM on the backburner till you are fully operational again, one less thing for you to worry about right now :/

:(
Condolences and wishing you a quick and fruitful recovery.

I'll patiently wait for you to catch up with my request!

Now i just need to find more sources of these 4kW monsters.

sorry to hear, i saw some of those 4k psu on amazon for 150 or so but do you really have to have the fans like finsky uses for them to work ? or do they over heat ?

I would just like to order the fan assemly and the dual fans I can get some PSU's from amazon i guess

Apologies everyone, but for the time being I am not accepting any orders.  I am not able to provide an appropriate level of service at this time, and cannot commit to reasonable timeframes. I will update in a few weeks once I get caught up.

No you can have those tiny blower fans that wreck anyone's ears. Its just a lot less noisy like this i guess? In some datacenter builds the fans are not always necessary.

Could you provide a link to the fan assembly mounting stuff? I am in the process of sourcing everything each piece myself.


"Get well soon."

Ready to buy a lot of them! PM me if available.

Very sorry to hear about your problems Finsky, I appreciate all the help you have been able to give me.

I hope this is not out of place, but I ended up buying more from Finsky then I ended up being able to use.

If anyone is still looking to buy these parts, I have the listed here for sale: https://bitcointalk.org/index.php?topic=2042493

@cheet
sent you a PM , finsky where art thou :(

Finsky, just checking in to see if you have recovered and are back in business.  I am looking for 2880 and 4K breakout boards.

+1

Also curious if you're taking new orders yet.  ???

I sourced my own parts, at least, PSU, board, cable, tie wrap. I'm wondering if there is a safer way to hold the 2 PSU strongly together, than i came up with? (Tie Wraps)

Because with a bit of push they move apart a little and the back of the board threaten to short with only a 3mm disparity. At a data center they were rock solid and i didnt think to pay attention to what was holding them together.

@Finksy if you still read this thread, i hope you're recovering.

i got all the pieces except for the "Steel sideplate and hardware for mounting fans".  Any other place to buy this?

I think he had that locally custom built by a metal worker. Maybe if you can get the/some plans you could have that done yourself.

unusable without a sideplate.  The reason is the cables are so heavy it drags the top of the breakout board down (like a pivot).  I contacted sloopy on the forums about how to get these but he never answered me.  sloopy is the machinist who made them for Finksy.

It seems Finsky has gone mia, no posts since july?

Who is selling this stuff now? I have the psu, but trying to get a 4k breakout board and cables..

https://www.google.com/search?q=zip+tie&source=lnms&tbm=isch&sa=X&ved=0ahUKEwisu-r-lf7YAhUBFSwKHauJAIMQ_AUICigB&biw=1280&bih=617

; )

Now. Before telling this is bs, I've been using DPS-es with cables soldered to mating connector which is tied to PSU with zip ties for years.
My oldest one is 3 years old. Zip ties do work.. Tho they do become fragile if temperature is too hot. And ofc use zip ties to only lock something in place - this something need not to put it's whole weight on the zip ties.

Optimizer user on this forum. 50$ per 2KW board.

Want to sell ur PSUs to me? ; )

Are these kits still available?
