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

[RickJamesBTC]

Where are you finding these PSU connectors? I have been looking for them for ages. Are these on digikey?

Yep, gotta dig through a hundred thousand models to find the right one

[sidehack]

The Z750P connectors aren't, at least not in stock. I have a jerry rig solution but for the next round I'll have to order from the factory.

In the very near future I'll have boards for the DPS800 and probably that 2000W fanless supply y'all seem to like; that one will integrate a PWM fan speed controller with internal/external drive options and at least one fan header.

Manufacture on the Z750P boards has been delayed by finances, but we should start rolling them off about the end of next week or early the week after. Hopefully the boards for other supplies won't be too far behind.

Find a backplane and ask them to send you all the numbers on the actual black connector IF ANY then search all or part of the number at digikey

I received a couple quotes for the 6pin PCIe power cables, and forwarded the best one to sidehack.  Still waiting on news from my vendors re: 51915 discussion.

Thanks guys, I have found what I have been looking for.

Had about a week's holdup with initial funding for a first batch, but we should be ordering the parts and PCBs before end of business today. Depending what happens, we should have orders opened in about ten days for the Z750P boards, and a solid design for DPS800 boards and for a several-supply control panel not too much later.

Bump for OP...the guy knows his shit.

Count me in for a couple.

[Bobs Yerunkle]

I have a Dell Z750P that is waiting for 1 of these once the bigger orders have been fulfilled.

Looking forward to seeing what the finished product looks like.

Finally found some information on to turn on the HP Common Slot Power Supplies:

Still looking for a connector though.

[BotwinBG]

I grabbed an IBM DPS-2500BB A and a HP DPS-800GB A 1000W for a few pennies, so if you're working on compatible boards, count me in for one of each, in addition to 4 Z750P boards.

[sidehack]

DPS800 is the next board we'll have available. Just gotta get some time to make one - in addition to Blade/Cube repair service and Z750P designs, I've got a "real job" and a few other side projects to juggle.


Also looking at cables; Cheshyr got some good numbers, need to find out a bit more information but we'll likely have cables available for purchase alongside the boards for around $4-$5 depending on wire diameter and length; this'll have a PCIe 6-pin and spade connectors already assembled.

[RickJamesBTC]

These are what I've been making for my DPS-2000BBs. Holy shit I'm tired of soldering and stripping wires. I need a cable manufacturer.

I've made almost a dozen so far. Nice part of the 2000bb is that I can run 7 r9-280x or 10 270x cards off each one. Probably more, as I think there is sufficient over capacity in the power supplies, but I'm leaving headroom.

Totally cool! I assume the pot is for setting volts on the 12V rail, Sata lines for riser cables, a few fan headers, and running the mobo off another cheap supply?

Do you think I could talk you into a close up of how you mounted all those wires? It looks like you've got them all directly to the pins, am I right?

no pot, that's a switch and a volt gauge to monitor. It's 12.3 volts rock solid. I don't need to mess with it. It's all soldered directly to the header plug  I posted earlier in the thread.

Hope you don't mind if I ask you any questions while designing the board for this supply.

I've got a few extra if you want one to play with. I've been meaning to come up with a good way to distribute all that power, the connector's terminals aren't exactly held in well and I'm afraid they'd be a problem at some point soldering directly to them.

Kinda why I wanted to see an up close pic to see if your connector was different, or how you dealt with what I'm seeing.

The little pins I'm only connected to the power on and ground wires. Then I gopped on some hot glue to keep the little bastards still.
The big power connectors aren't goin anywhere.

[sidehack]

That's how I did my first test, wired straight to the supply terminals with pin header plugs and hot-snotted the whole thing solid.

The Z750P connector is not the same as on the 2000. I think, actually, that the Z750P is the only effin' supply that uses that connector; there's a bunch with the same pinout but ever-so-slightly different spacing on the power blades which is why it's hard to find mating connectors.

That answers my question pretty well, thanks! The little pins can do some pretty neat stuff from what I've been reading. Hot glue sounds like a good way to keep them from doing neat stuff when you don't want it to. I'm also glad it runs 12V pretty steady without any further control needed, I thought it might take at least a resistor to set the 12V..

I'd agree that the big ones bite down pretty hard, I don't think they will go anywhere either. Those terminals slide out pretty easy when they aren't connected though. I was planning on clipping all the little pins off and soldering gangs of wires down inside the terminal.

Sucks about that other power supply connector, I just searched the P/N of the socket and found the plug P/N on digi's search. I'm sure you figured that out though, guess I just got lucky picking these supplies
