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

[bobsag3]

Pretty sure that's right, they require 220/240.

Yup, they are 12A @ 200-240

Hi,
Im from the uk and have been converting some dell 670watt 1u psu's.
Just found a DPS-2000BB on ebay!! gonna get it but what adapter peace fits on it (product num)
Thanks,
JT

Any boards and/or cables left in stock?

Also a question - if I have my standard PSU powering the motherboard etc. how do I daisy chain the Z750 PSU powering the GPU's so it all powers at the same time as in the mobo and GPU's?

The board's EON input takes an active-high voltage to power on the supply.

I haven't built one yet, but it's being prototyped and I hope to have boards available by the end of the month. Should have info later this week on DPS-800GBA board progress, and I'm waiting on some parts to come in before doing any active tests on DPS-2000BB stuff.


I'll probably be reopening orders on the D750 boards around Thursday. I'll make a post here about it, but the actual sales info will be in a post on the Group Buys forum. It's a little more appropriate for conducting business. I'll have boards, cables and full kits (with PSU) available.

I made sure that my new "deep" scrypt mining frame supported this board.

I'll be keeping an eye out for the new thread in Group Buys.

I encourage anyone following this thread to consider these boards from sidehack. 

Quality product from a quality guy and his underlings!

Sales officially open 9AM CST. Got about a hundred boards, and we're offering full kits including the power supply.


Had what I hope turns into a good idea today, for the DPS-800GBA boards. Those supplies are pretty handy, with just about everything already integrated and broke out - except I didn't find any information on current share, nor was I able to determine experimentally any load-balancing ability. But I think I figured out how to integrate it into the interface board. It'll take some testing but if it works you'll be able to parallel and load-balance the DPS-800 also - hopefully while still also allowing user voltage adjustments (up to ~14.5V, sweet).

Speaking of DPS-1520AB A, does anyone have a pinout for that?

Pin A1 to B1 to power up

Do you know the rest of the pinout?

Hey!

I'm reading this topic almost since begginig of it.
I have bought DPS-1200BB, which will be used for GPU mining. I assume you all are talking about ASIC mining here, correct?

After reading your debate i got confused about wiring. Does ASIC miners need more current then GPU? Because 8pin connectors with wires that i bought got 3x 20AWG (cables are 30cm long (12inches)...
Is this enough?

The boards sold here to work with the server PSUs could be used for either GPU or ASIC mining.  I believe its a toss up in terms of which draws more power GPU/ASIC due to the hacks and overclocking mods now on some ASICS that allow for more power/performance use.

If you are considering GPU mining I would suggest that you have at a minimum 18AWG wire in runs of less than 2ft.  From my understanding the cables sold here are 14 or 16AWG which yields more safety headroom.

Yes everything here is a good and safe bet for ASIC and GPU Mining

Is the DPS-1520AB 1440w?

And is it safe to have It power Four Gpu's, and have a seperate 650w psu to 5x powered risers, and another GPU?

EDIT/ Worded better -


Can you tell me if I need a seperate PSU to run the Motherboard AND the molex on the powered risers?

Or the Molex on the powered risers can be wired into the DELL server PSU?

Thanks

Let it be known that I am a curmudgeon by nature, and therefore will start responding to these messages by saying "RTFThread" and a link, as all of these questions have been answered repeatedly in the thread people claim to have read. It's been stated that I currently have boards for the D750P/N750P supplies, and will within a few days start prototyping DPS-2000BB and DPS-800 boards.

No. Not the DPS-1520AB.


As for running GPUs, you WILL need an ATX supply of some kind to power your motherboard. You should be able to run the risers off the D750, hopefully someone else can verify that. But motherboards require more 5V and 3.3V than these will source so a separate ATX is necessary. If your board is low-power enough, you could get a PicoPSU and run it off the 12V from these supplies.

[Mk2vr6]

What I meant was -

Do the Molex Powered Risers need to come from same 12v rail as the motherboard?

And also, how much power is drawn through the powered risers, do you know?

[sidehack]

Seems like it wouldn't be necessary. I don't think anything cares much which 12V rail, as long as there's a common ground. I haven't used any risers but others have been strapping them to home-rigged server supplies without any problems... I think. Someone'll surely mention it. Odds are it's been talked about sometime in the thread so far though.

PCIe standard allows 75W through the socket, 75W through a 6-pin and 150W through an 8-pin. So the riser, taking over for the socket, should top out at 75W, or at 12V 6.3A

Thanks for your help. I've read through the thread a few times and didn't see anything. I've got my head around this now, so time to get it all put together!

If you are really paranoid, cut the 12V lines on the ribbon risers. Should not matter either way though.

I prefer USB risers, they are naturally isolated from the motherboard, at least for power. I treat them as a 75W load (though it's closer to 30-50W in my experience) and balance them across as many supplies as I feel necessary.

Oh, and regarding your initial question "Is the DPS-1520AB 1440w?" I've gotten used to dealin with people with horrible grammar, and people asking about different models, so that I misread it. A quick glance at the Internet tells me it is a 1440W supply. If a single GPU doesn't pull more than 360W then technically you'd be within range of the supply with 4 GPUs; for longevity I'd try not to pull more than 325W (90% load). PCIe standard doesn't really allow for more than 300, but not all high-end cards are standards-compliant with regard to power usage especially when overclocked.

[claudesdad]

I'm interested in some of the boards for the Dell 750W power supplies - sent email to the address at Gekkoscience but haven't seen a reply yet.   Looking for 4-6 boards - with the cables.  How long are the cables on these?

Admittedly, I didn't word my question very well, and even my edit isn't much better! 

Can I pick your brains while ive got your attention?

I have:

2x 280x VaporX's (300w each?)
2x VTX 6950's (280w each)
- These will be running off the DELL 1520ab.

I will have one more 6950 and 5 powered risers and motherboard running off another PSU.

Can you suggest what wattage PSU I would need to power the MOBO/RISERS/6950?

Thanks again.

[sidehack]

Preemptive disclaimer that I don't work with GPUs a lot.

But I would imagine the 300W and 280W from your cards, part of that is coming from the risers. If you don't plug the risers into a heavy external supply but run them off your ATX, I'd allot at least 6A of 12V per riser. If the 300W/280W is straight external, they should all run off the DPS-1520 without issue. If that includes the socket power (from risers in this case), you could power the risers off the DPS-1520 and still only be at 80% capacity.

If, then, you ran your 6950 and motherboard off the ATX supply, I'd recommend probably at least a 500W unit. Maybe more depending on what processor/motherboard you're running, and what overhead you want to allow for.

What you could do, and an idea I've toyed around with but haven't tested yet, is actually get two server supplies in parallel load-balanced (I don't know enough about that particular model to know if they current-share or not, but I think most do) and get a picoPSU running off the 12V bus for your motherboard. Those things aren't terribly expensive, and run around 96% efficient. If you isolate your riser power from the motherboard power (either by using the recommended USB-style risers or cutting the 12V lines to the ribbon) you shouldn't overload anything on the picoPSU by trying to pull GPU current through it, and anything else requiring 12V (like GPU, or processor VRMs) would pull straight from your ~3KW 12V source.
