March is Neptune

Which supply is that? Is that for the DL360?

[RickJamesBTC]

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.

This looks like the info you need. Do some testing, be careful

I believe the blue wire would be a power on signal, you could wire a standard switch between them to have control, the red wire would be voltage sense, so it knows it is on and can regulate the voltage. Hook up as shown and measure voltage on the pads. Hook up some loads to it, if you are going to run cards from it, start with one, check voltage, add another, etc. if you have an amp clamp you can check how much load you are pulling to see if it works well.

OK got it.

Could you verify the 6-pin connectors...


Are these correct.
Do you put power to 1,2&3 and ground to 4,5&6 or do you skip any?

If I'm thinking right, the fans in those are self-regulating based on internal temperature. Anyone know a more complete pinout, like the power-good signal and current share? I'll have a couple here in a few days to play with so it'll be no problem figuring out, just wonder if anyone's seen a more complete pinout listed somewhere I haven't yet looked.

Yellow is power, black is ground. Don't skip any.

Currently gathering resources for a first batch of these boards. The bulk are already spoken for, but I should have a few dozen available in about two weeks. If folks are interested in making cases for these, let me know and we'll work something out for getting samples/small orders to you.

The current board is about the same width as the Z750P power supply, so they can be put side-by-side. The output pin header includes lines for 3.3V standby power, an integrated 5V 3A supply (powered off 12V), current-sense signal, external fan speed input, auto-on input, power-good and current-share outputs.

I'm also trying to make available 14AWG/24" PCIe 6-pin cables with spade terminals on one end for mounting on the screw terminals.

Working on dev for a controller board that will integrate power supply health and per-supply/total power output, as well as thermostatic fan speed control and maybe some other bells and whistles. Also working on boards for the DPS800 interface.

If you ship to the EU and take bitcoin as payment, I would like 4 of those, case or no case.

[elchorizo]

In for the sub, interested in these as well.

[klondike_bar]

heads up, here is an even better/simpler PSU. 835W, easily jumped PS-ON (pins 3+4), and pairly easy to solder in a few fat wires without fear of shorting them to oneanother

Hey awesome work sidehack! This will be really handy. I've been watching this thread with interest for awhile now, stumbled onto it by accident doing a google pic search. I picked up some bladecenter DPS-2500BB, plus the 2000 and 1800 watt variants, they work excellent for power GPU's but are simply too much work to wire up on a large scale without the help of a device like you will be producing.

Just curious are you talking to someone overseas to source the PCIe cables or here in the USA? Overseas certainly would be more cost effective likely, but if needed I could crank out cables to spec to supply members in the forum or in trade with you for some of your adapters, just an idea. I've been building mine about 2-2.5' long with 16 awg wire. I would advise against using speaker wire, course strand 11-20 conductor control wiring type works excellent.

Oh and I can also supply brand new 60mm fans for the power supplies, I've been using 3M double sided tape on one side of the power supply to attach them and works perfect, they are a bit on the loud side b/c they move a lot of air. Below I've posted the link to some pics of my ghetto wiring, the fans and one of my rigs.

I had a cables contact already, getting bids from him for production which is, unfortunately, overseas. I'd prefer domestic manufacturers, and Cheshyr is following up on some leads for me in that neighborhood. The initial batch's primary customer has requested 24" 14AWG, and I figure having spades crimped on the other end will be really handy.

So you're going to solder pcie? What about the 12v sense?

Hmm I think you will have problems being able to use 14AWG for PCIE cables because the PCIe pins themselves really only accept up to about 16AWG. All the wiring on a standard store bought power supply that I've seen is 18AWG (for PCie) so to use 16AWG its already a pretty tight fit. For a distance of 2 feet 16AWG is adequate, the bladecenter supply also puts out 12.2V so that helps too. To go longer you can use 12/14AWG from power supply to a push connector or marrett and then from there 2 feet of 16 or 18AWG PCIe cable. Becomes much more work and not as pretty though. You've probably seen this but you can always check out this handy calc if you're not sure or want to use longer size wiring. http://www.powerstream.com/Wire_Size.htm

I'd be fine with 16AWG; all my stuff is currently running on 12 inches 18AWG which is too dern small but it's what I had. 14AWG was requested, so that's what I'll deliver to the requestor. He's been smoking 18AWG wires.

I'm building my extension cables for the dps-2000bb with 12awg, each of four power outputs should be able to run two GPUs. I should have pics of my first efforts later today.
