The only thing I liked in that video when the guy turned two supplies on and the fans drown him out.
He had trouble showing off some  of the fan controls what you see in this video has to be in top ten videos not to sell your product

Any chance you have one more of the DPS2000 boards left?

Thanks

Yeah I really don't know what most of that means. On the breakout board front, Novak's working on a new edge-connector board but prototypes for that won't be ready to show off until about the same time I have pods to show off (probably around two weeks).

I wonder what mister proff's up to.

Yep, this is a really old thread. It was replaced almost a year ago and left to the archives. I'm also not sure what you mean by back-order mentality, but it sounds like something I don't like either.

Being as I've been out of stock on these boards for a while due in part to cost and in part to limited demand, go right ahead. But when you announce your product, please do so in your own thread.

sidehack, i do not know what you and novak are going to do...

prof.hell, is in town, and that is 2 L's in hell

I know I cannot wait to see what product comes with my very own prof.hell wrapper. Roll Eyes

Boys and girls,

I know this looks like a reaaaalllly old thread, but in case anyone's interested ..

I didn't really like the approach of how the breakout board is doing it, nor did I like the back-order mentality.  With that in mind, I went ahead and designed my own PCBs, which I believe offer a better approach.  Validating the prototypes now and results look good.  Expect product to be in stock and ready in the next two weeks.

Once ready, I will post a link to where my boards can be ordered from and a price.

Thanks,

the prof.hell

So, I've put up a consolidated post with all of our offerings in the Marketplace/Computer Hardware section. I'll be maintaining that as the official purchasing thread, I reckon, with updated prices and information.

We're still selling from standing stock. All boards and cable lengths are available. We're also able to do custom-option cables (wire lengths, spade/strip terminations) with a couple days' lead time.



Additionally, some news. How much interest is there in DPS-800GBA and DPS-1200FBA PSU interface boards? We've got a working prototype for a single board that works with either PSU, but we need to be sure there's enough interest to merit building it. Expected per-board retail probably around $35 plus shipping. We'll probably be adding a 5VDC line to it, with a USB plug for powering Pis and such, but that feature might not be in the base price (probably add about $3 for parts and labor).

Also, we have reduced prices. Price breaks are now $55, $52, $50, $48 for the quantities listed.

Pretty soon we'll be able to offer more or customizable cable options as well.

Yeah I guess the title needs to be updated.

In any case, the prices in the first post are the current prices. We had a housecleaning sale a few weeks ago and dropped all prices, but that has ended.
We're still offering a 10% discount to anyone purchasing to power hardware from Canary or CrazyGuy Prisma GBs though, just gotta let us know that's what you're doing. There's no particular reason, just we like those guys.

Novak and I were discussing pricing the other day though, so I'll talk to him and see if we're gonna make any changes. As of right now, what it is is what it is.

sidehack,

Is the price still "reduced" -- or does the thread title / OP just need to be updated?   (I saw conflicting info -- one post said through the end of October, another suggested the sale would last until the Prisma group buy had concluded...  Etc.)

If things are still on sale, could you maybe...say what the prices are, because the original prices, the dropped price, the discount amounts, and the recent sale -- it just...um...seems kind of scattered about all over the place and it's  kind of hard (for me at least) to figure out what the actual *price* is.

I realize I should be capable of locating this information -- but I formally admit defeat and would kindly request a current price list, just whenever you get the time...not a rush or anything.  Thanks!

Our boards were designed for a 240A rating, and the first one was stress-tested to 200A for a full seven days with zero problems. It was actually a current-sense board, so the PCB had to deal with the extra heat of 200A shunts and still performed beautifully; stock boards will do even better. They should be alright for a DPS-2500BB.

The only thing about adjusting the DPS-2000BB settings is, over-current is an internal pot so you might have to take the case apart - which is actually very easy. Overcurrent protection usually kicks in just shy of 200A but can be adjusted up over 210A I think.
Output voltage adjustment is not implemented on our boards, partly for safety reasons. We didn't want someone grabbing the wrong knob and roasting all their hardware accidentally.

This particular PSU was used in IBM BladeCenters. I think each 6U machine had 4 PSU in it. Not sure if they had any other purposes from the start.

FYI, as far as as I can tell from looking at the pin outs, the DPS-1600BB (147.5A @ 12.2V 1800W), DPS-2000BB (164A @ 12.2V 2000W), and the DPS-2500BB (205A @ 12.2V 2500W) are pin compatible and the DPS2K adapter board and should be a "Plug 'N' Play" on these supply's.

Just ordered qty 16 DPS-1600BB's and when they come in will test and report back.
We scarfed these in the salvage market for $8.74 each + $10 shipping.
Total cost each was $18.74. Helluva' supply for $20.

These supply's have NO internal fans and in a stock configuration (i.e. installed in an IBM BladeCenter) are cooled by case air.
Adding 40mm fans to the side of the power supply case for cooling is MANDATORY.

We anticipate using these in our mining farm to power OC'ed AM Prisma's.
One supply per Prisma.

Of other interest is, the efficiency of these supplies under light loading (250W draw) is 87%, at or near rated output the efficiency rises to 92%.
So from a Bitcoin mining perspective it's better to run them WOT (Wide Open Throttle) than to be conservative.

Individuals in the RC community have reported about the DPS-2000BB's that when tweaking the output voltage to 14.6 and tweaking the Over Power Cutoff the DPS-2000's can supply 2800W (~200A @ 14.6V), Booyah!

Thanks Sidehack! A quick wiki search yielded this juicy picture:

(They look a lot more shiny and new than mine LOL)

Can I stray a bit off topic and ask the question: What's the back story of these surplus power supplies? They seem to have made a lot of them. Did they actually go in server computers? I was thinking maybe they used them for powering wireless telecommunications? That would explain the trainloads. Does anyone have any of these power supplies that came with a history?

All orders placed between noon Tuesday and end of Sunday (10/26) can get a special discount pricing. All DPS-2000BB interface boards are $45 in any quantity; 18" cables are $2.75 and 36" cables are $3.75 apiece in any quantity.
