Dual-purpose DPS800/DPS1200 breakout board

[sidehack]

So, I have finally gotten to production on a project well over a year in the making. The first working prototype was completed shortly after Christmas 2014, followed by a complete redesign and a bunch of other trouble. But now we have the new product hooray!

What I've got is a single breakout board which will work for both the DPS800GBA PSU (850W@120V, 1000W@240V) and the DPS1200 (1000W@120V, 1200W@240V) PSUs. The board can be built with either our standard screw terminals (2x 4-position per rail, twice as many as the Dell 750W board) or 12x PCIe 6-pin terminals.

The board has an on/off button (toggle switch optional), standard status LEDs (green standby, blue 12V), optional 5VDC aux supply, and our standard 10-pin IO header. POK and External On are functional, as well as 3.3V standby power. Current sense, current share and external fan are not connected. The PCB is the same width as the PSU, so they can line up side-by-side without wasting any space.







This S7 has been running in my hosting since January on one of the original test boards. It's a bit smaller, built with only 10x PCIe but we had to change things around a bit to make connector spacings better.

Board prices start at $32 for single quantity down to $25 for lots of 100. Cables (either spade for screw terminals, or double-ended PCIe) can be had for $3 for 18", $3.30 for 24" and $4 for 36" cable.

Right now (4/19) I'm making up initial bulk orders so it'll be a couple days before I have standing stock available to ship, but a couple days isn't bad. An order placed now would probably ship Tuesday 4/26. I have about half a dozen DPS800 PSUs but I don't have any DPS1200 PSUs available for sale at this time. I'll stock up as soon as I can.

Philipma1957 received one of the first test boards from this batch a couple weeks ago. I'm hoping he'll chime in with a review.

if you will sell me one right now i take one and buy it tomorrow Ive been waiting for you or opt to come out with some good break out boards for the 800/1200 so i can run mine again and feel safe and not have browned out PCEI plugs .Ive been using OPt broads on two of my 2k PSU i use and need some good boards for my 3 1200 so i can power them up again and feel safe. or direct me to a re seller i don't care were i buy it.

need one now and two poss next month about the same time .Im good on cable have a lot on hand as back up.

Awesome! I love to see these projects come to life! I dont have any of those PSUs but I do run the DPS2000's and use your board for them. Great quality product!!

Works for me if it works for you.

Interesting that the DPS1200 is running an s7... At the wall my s7's pretty much are all pulling 1,290w each so DC power out to the s7 has to be near/at max I'd think. Safe bet the supply's fan is in hair-dryer mode, not that it matters considering the s7's spl. No problems with it? If not,hmmm. I still have several of them around and beats buying more Bitmain supplies....

I wonder what the DPS1200 hold up time under full load is? (for power glitches) Gonna have to find the spec pdf on them again methinks.

edit: Found the link to HP's pdf Quick specs on all (and I DO mean all!) of their CS supplies http://www8.hp.com/h20195/v2/getpdf.aspx/c04111541.pdf?ver=2 I'm surprised there is no mention of hold up time.

I am running a head to head test.

  using sidehacks new break out board  with some 16 gauge cables and a hps 1200 psu.


it is running against a new sealed fsp aurum 1200 watt psu.

a link to the psu
that uses  sidehack break out board.

a link to the aurum 1200 watt

I just set this up today.  the used server with sidehacks board is match the new 1200 watt atx

Cool. How's the PCB temperature around the jacks in use? The board is 9oz copper total, so 4.5oz per rail. Normally it's full thickness per rail on my boards but with the matrix of 6-pins that's not really possible. Still, I think 4.5oz is probably thick compared to most other boards.

glad you asked I purchased an infra red

here are the shots with it  about 4 or 5 hours runtime every number was under 52c

the big 'flaw' is I need to figure a good way to support the card and allow air to circulate 
the solution I am using now is temporary

[NotFuzzyWarm]

Philipma: If you check that link I gave to the HP supplies on p.15 you'll see that they have 48vdc input supplies (36-72vdc range) and since you are into solar... eliminates substantial inverter losses I'd think.

I will need to ask buysolar if it helps as he has about 70kwatts in inverters installed.


over night the numbers are

3327  gh 11.9 volts = sidehack board and a hps 1200
3328  gh 11.9 volts = aurum 1200 gold


So on a short test it is good.

[judypug1956]

Any more shots of the test setup?

[philipma1957]

Any more shots of the test setup?

yes

garage door is shut as I want the test arer to be pretty hot it is 89f



my edition has prototype black jacks attached to the 1200 watt at 240 volt server psu.

my tests are on a 120 volt circuit

using an empty rasp pi   box to support the breakout board
using a clamp to keep the psu steady



using a 1 2 3 block to allow cooling to the server psu
note the aurum 1200 watt psu which is matching the  server breakout in this comparison test

Any more shots of the test setup?

Did you wife just ask you that, or are you talking to yourself?

I get many pm's that tell me not to double post.  So my wife helped me out and did that question thus I did not double post.


back to photos  top hook up is the server break out board hook up



my thumb is next to the on off button.

nice button feels costly



better shot of my support of the breakout card
looks to me if you pick up these cards there are two ways to secure the card and the psu.  my setup now does not reflect a long term method
later today I will post a better way

[Mikestang]

Nice looking product.  I just purchased the 1200w HP server psu from HolyBitcoin and it had a board from J4bberwock, but I like the additional features you board has.

Phil, I have my psu suspended from the metal racking that my miner sits on, I'll take a pict and post it but it allows good ventilation around the psu while not letting any of the contacts on the bottom of the break out board touch the metal racking.

The HP 1200W supplies really do not need airspace around them, just free space at the ends for air in 'n out eg, part of my farm from 11mo ago, https://i.imgur.com/J4uUYAa.jpg https://i.imgur.com/rbcz0pw.jpg and https://i.imgur.com/OochrCC.jpg

That's 6 of them packed in a 2U high brick. During the summer it gets up to >85f in that area and never had a problem with them. Do they get toasty to the touch? Well yes but that is how they are designed to run 24x7x365. As a rule of thumb I keep max load on any PSU to around 80-85%.

[LASERminer]

...Safe bet the supply's fan is in hair-dryer mode...

They never go really loud.

Yes the HP Common Slot power supplies really do not need airspace around them.
Agree, in HP servers I see several types every week there is no much space on DC side.
Check out original HP breakout board (in cage), notice amount of cables going out, know there are big radiators in the cage and this is attached to TWO PSU's at once.

[philipma1957]

my server hp 1200 is really quiet.

some how it is so quiet i find it amazing.

I came up with a perfect mount solution.

let  me photo it.

left over 1 ½  by 1 ½ tubing



cut to 1 foot or so

and some electrical tape  for no shorts
clamp holds psu





clamp is nice

[LASERminer]

...The board has an on/off button (toggle switch optional), standard status LEDs (green standby, blue 12V), optional 5VDC aux supply, and our standard 10-pin IO header. POK and External On are functional...

1- Any chance to get 5V standby?
2- Any chance to make one Raspberry Pi controlling power-on/off to several of these boards?
