Server Power Supply Interface Board - for standalone miners and GPU rigs

[pontiacg5]

Ok, yeah, the 51761 and 51762 series work well for stuff with a 0.250" pitch on the power connectors, and they're generally in stock...  we're still chasing down the 0.200" version.  We've got part numbers now (51915 series); it's just a matter of finding something that actually exists, instead of phantom active status parts with no stock anywhere in the world and not insignificant minimum buys.  One of my suppliers responded this morning, and they're looking into it for me, but it's still an 'everyone is on vacation until next week' sort of deal.

It sounds like we've got quite a few power supplies that people want to support, all with different interfaces.  We should probably put together a list of the most popular ones so we don't miss anything.

I'm in the same boat, except with PCB manufacturers. Everyone's gone for the holidays, hoping it gets better soon....

I'll keep an eye out on this thread and add info I think will be helpful

Can you make one for supermicro power supplies too? I'd be willing to buy a ton of them if they were supermicro compatible.
Something like this  http://www.ebay.com/itm/NEW-SuperMicro-CSE-PT823-PD5i2-2U-Power-Supply-Backplane-/220979395258 except made with PCI-E connectors in mind.

Got my first 5 protoypes of these today, they are working perfect so far. Going to conduct some tested with the dell 750w, will report back.

[sidehack]

Definitely test the load-balancing on those if you can.

I can confirm that these
http://www.digikey.com/product-detail/en/51762-10802400ABLF/609-4020-ND/1492063

are the correct connector for the dps-2000bb power supplies. I'm currently building them into harnesses for the 12 supplies I have here. Can't wait, running these should drop my power supply costs tremendously. I'll be testing current draw on them with a variety of cards, but if other sources are correct, I think 2000+ watts worth of cards can run from each. Imagine 6-7 r9-280x or 10-12 r9-270x per $40 supply!! (plus harness stuff, which I'm making)

Could you help me locate the ones for these power supplies.

I don't have the supply so I can't tell. I have these plugs and supplies here, and have physically confirmed they work.

Found this site which may be helpful However did not find the info I needed yet.

I read that page many times. Take a picture of the connector port on your power supply and post it for me please. I'll see what I can do.

[sidehack]

The DL360 is next on my list to build boards for. Hopefully I have some better info on those sometime next week.

In the next few days I'm gonna run up some test procedures for the Z750P boards, which should make for an interesting writeup. With any luck we'll start mass production by the end of next week.

[repairguy]

were you able to twin the supplies.

[sidehack]

Still having trouble finding a reliable source for the Z750P power supply socket, that isn't about 6 weeks out.

Working on pinout/interface for the DPS-800 HP power supply. I've gotten information enough to turn them on, but haven't turned up an actual pinout of the signal lines yet but we'll get there.


Is there another people want boards for? I'm seeing a lot of reference to the DPS-2000, so that's a possibility so long as people understand they're gonna need to rig up fans. Suppose I could put a fan header on the board.



As of now we're including a 5V 3A output, which was requested as some standalone miner devices need a 5V line to power internal controllers. It'll break out the 3.3V standby, give option for external fan control, and supply an output current measurement signal in addition to auto-poweron, power-good detect, and current balancing. Hopefully I can locate/derive enough info on the DPS-800 and DPS-2000 to implement the same features.

You got until March

[sidehack]

Why, what's March? There's people that want these yesterday.

[jlsminingcorp]

Why, what's March? There's people that want these yesterday.

If you can't do them yesterday then tomorrow would be fine . The feature list sounds great by the way, thanks for all the hard work.

[jlsminingcorp]

I've been looking around for the pinout on the Z750P to get one switched on for testing, but I'm having trouble tracking this down. Does anybody know if the pinout is the same as on the NPS-700AB (see pic below)? The connector looks the same, but I'm guessing that the pinout could be different. Any help gratefully received .

[sidehack]

That should be enough to get it turned on and spitting out 12V.

[jlsminingcorp]

That should be enough to get it turned on and spitting out 12V.

Great stuff, thanks.

[BotwinBG]

really interested in getting 4-5 of these.

[sidehack]

Depending on funding availability and whatnot, I might have some ready by the end of next week or shortly after. I'll definitely keep the thread posted.
