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

[Cheshyr]

Bobsag has offered to put up some BTC, but I'll have to decide how to split that up between the cables he wants and an order for these connectors. And then decide how many connectors we want to order.

 I can confirm I put up some BTC to get this project rolling.

Since I have the contact and quote, I could probably set up a Group Buy for the 51915 part if that's the desired route.  I can convert btc to usd fairly easily, so there wouldn't be a delay.  Our order would have to be in mults of 99, with a min of 198.  So, 198, 297, 396, etc.  We'd need to decide whether to cut off at the lowest full increment, or sit on the extras from a slight over-order.

Just offering, in case it would help.

edit: In retrospect, this may also be a terrible idea.  sidehack has a plan, so let's see how he decides to work this out.

I would also be interested in boards for the 2000W PSUs if you ever get around to them.

[sidehack]

Oh don't worry, I will.

We're gonna talk over the timing for the next few weeks, likely gonna be placing a somewhat large order with the factory for those connectors for later rounds of manufacture. Should have DPS800 boards within 3 or 4 weeks, and probably 2000W boards about the same time.

Same here. I'm interested in the DPS-2000BB boards.

[pontiacg5]

I'm all but certain all DPS-xxxxBB supplies use both the same connector and pinout. From looking at many, many e-bay ads I'm nearly certain they are not only the same connector, but the same form factor too.

Let me know if you would like any help, but I am pretty busy making USB riser cables

243GH Bitfury rig and 190GH Antminer running on a single Delta 835W Server PSU with AWG14 cabling that doesnt get warm even when moving over 200W per wire pair

2000W for £50....

Any chance of making a board for it?

[sidehack]

Isn't that the DPS-2000BB? I have a couple on the way for experimenting with, and am planning on building a board for this one.

[spoonuk]

I think you're spot on - it is the same PSU!

Still you just cannot beat 2000W for £50...

How long before we can see boards surfacing?

[sidehack]

I've got a couple on order should arrive next week, and will be gathering parts to prototype over the weekend. Probably nothing going out before the end of the month, but three or four weeks might see a production run. Takes a while to get all the various ducks in a row.

[freddyfarnsworth]

Ok, the FCI 51915-064LF part discussion has come to a dead-end.  Our only option is to place a large enough order to get the factory to manufacture another run.  Minimum quantities look like 200+.  Do we have that much interest?  If so, we have a couple ways to move on this.  I've got quotes for ordering these, which I've forwarded to sidehack.

What HP servers was this used in ? I have alot of old xeon servers. DL760 era. PIII xeon 900mhz 8way.

My hands hurt from stripping all these wires for pci connectors....

Are you using an auto stripper type?  Like this: http://www.lowes.com/pd_473081-295-SA822_0__?productId=50081506&Ntt=wire+stripper&pl=1&currentURL=%3FNtt%3Dwire%2Bstripper&facetInfo=

Saves on work.

[RickJamesBTC]

Oh I've got every tool you can think of, been wiring cars and everything else for a long time. Doesn't matter what the action is, you do it a few hundred times in a row, it's gonna hurt.

By the way, these are the best wire strippers ever, apart from having another person to do it for you.

The DPS-2000BB uses this backplane connector.  Ordered two of the PSU and two connectors, both just dandy.  Can't wait to see if you get a working interface board with these PSUs.

[sidehack]

Yep, that's the connector I have spec'd to prototype with.

I see the DPS-xxxxBB have no fans. How would one cool it, if it is even needed?

Op board has headers and I think you basically zip tie one on

i think a couple of small side fans 40x40mm might be the sollution.
