Topic: [PRICE REDUCED] DPS-2000BB 2000W Server PSU Interface Board - page 3. (Read 62074 times)

hello thier, i set up my DPS-2000B and works for 40 seconds and it shuts down it get's very very hot? can hardly touch it what can be wrong?

Cool, will do now

PM or email, let's go over some numbers and see what comes out.

We do all the assembly in house (with real Americans; we will never for any reason outsource anything to foreign countries). We also don't really like the idea of not-flexible options, so soldering a fixed number of fixed-length cables to the board doesn't go over so well. If we knew we were going to be able to sell a couple hundred we might go for it, but since batches of anything aren't per-unit cost-effective until you start making at least 250 and the capital cost for 250 of anything is a five-digit number, we aren't going to jump into something we don't like and hope it's not a huge waste of money. If someone came in and wanted at least a hundred, and paid down on the order, we'd do it.

dance191, how many would you be looking to fetch if the price was right? Nothing wrong with discussing some options.

I'm not sure where you get these assembled and what the manual labor costs there are, but have you looked into a cut down version without the screw terminals and only the PSU connector and a cheap on switch and just directly soldering 12 36" PCIe cables to the board?

I was figuring that the PSU connector -> PCB would get the cost to less than $4,450 for 100 (you said there can be about $4 and $1.50 in savings each).  Looks like I am wrong.

I have followed this since you released the ones for the dell 2950 PSUs.  I always thought, maybe if he used some of the larger IBM PSUs it would be more cost effective due to the scale of the larger supplies.  Then you buillt one for those as well.  I was happily surprised, but still never able get the price to where I could order a bunch.  Just seeing if there is a way to make it work.  Thanks for your input. 

The bulk of the cost is in the heavy parts, really. The PCB is a four-layer board with 14oz copper in the main traces (should be good for 240A), and even in the quantities we buy, the PSU connector and screw terminals aren't cheap. Add the labor cost of assembling and testing each one, and the "we like being able to pay the bills" necessary markup and there's not a lot left. Knocking off the fan speed and 5VDC circuits saves about $4 in parts and labor. 3V3, POK and EON collectively might drop another $1.50 or so. Depending on how many you're wanting, we could work out a custom-populated batch or, for orders large enough and with enough lead time, a completely custom design.

Also, I'm deliberately not responding to order requests in this thread because, well, RTFP.

Sidehack, love you work but I have a request.  Is it possible to get just a very stripped down version made?  Something that just plugs into the PSU and provides connectors to PCI cables (or is just hardwired to a bunch of PCI cables would be better).

It is great that you can add a bunch of features, but I think those features add to the cost and it is all about getting the cost down.  All the things like external fan control, current sense output, 3.3VSB, 5V2A, POK, external turn-on, and current-share for load balancing would never be used by me.  Just something that can go from the PSU on one end and PCI out on the other would be the most perfect to me.

Overall, I love your work but I am curious how low the price can get.  When it is still $50 even when buying 100, I feel there should be a "no frills" model.

Thank you very much!

 Can I get on the list for 4 more boards please, with 32 36 inch cables please. I just ordered the PSU's.

I'm going to officially announce the start of the Round 2 (pre)Order for the DPS2K boards. PCBs are on order, we got a full inventory of all current parts stock and expect delivery of the remaining parts early next week. PCBs should be delivered on or before October 3, which giving us some buffer time to create stock (and for the board house to screw up and ship late again), we should start moving boards on or before October 10th.

Pricing is the same as last time.

We will have a limited number of PSU Kits available (probably about two dozen), packaging a DPS-2000BB PSU, one DPS2K interface board, and twelve 36" cables for $154. That may not sound like a great deal when you add everything up, but that's the shipped price so it actually saves you $15.

We kinda got shafted on the last few rounds with people requesting large orders and then taking their sweet time paying (never knew a guy to take two consecutive vacations with exactly enough time inbetween to respond to emails but not log into PayPal...) so we're making some rules. If you ask for something, you have exactly three days from invoice issue to pay for it or the order is cancelled and you lose your spot in line. When we start shipping from standing stock, no matter how much business we've done in the past, nothing will be shipped until the order is paid in full. The official queue will be assembled in the order that payments were received. The only reason we're not shipping from standing stock right now instead of in three weeks is because we didn't enforce those rules on the last batch of shipments and some people took advantage of that. We will not make that mistake again, as it hurts us and every other customer entirely too much.

Additionally, a note to any overseas customers. If you're in a place I have a reseller covering, I will redirect you to that reseller and that reseller sets his own price as necessary to cover his own expenses. If you're not covered by an existing international reseller, I can ship to you but know that I do not falsify customs forms for any reason ever. The listed contents will be accurate, the pricing will be accurate and it will not be labeled as a gift.

So, if any potential customers could direct themselves to [email protected], and I'll only respond to messages with ALL OF THE FOLLOWING INFORMATION:

1. Exactly what you want (how many kits, how many boards, how many cables of what length - please be specific)
2. Exactly how you would like to pay (if BTC, say so; if PayPal, say so and also provide your PP address for invoicing)
3. Exactly where it needs to be shipped (any details USPS will need to know to get it there the first time)
4. Your forum handle (optional, if you want to be recognized on the public order queue)

yea awesome dick move me man! You rock.....3d printer shipped.

Deal! You rock, PMing you now and I will get this PSU out today/tomorrow as well, it's already boxed up.

If you want to do a straight trade, that'd be fine.  Just PM me your shipping address and I'll pay this way, you pay the return shipping of the dps2k... good?

Word! Did you want/need this DPS2kBB PSU I've got here? I will dig up your info and have a label sent your way asap, gotta run a couple errands soon. Thanks bro!

I can send you what you need, I recently upgraded from the 750's, so I have a ton of PSU's and boards sitting on a shelf.  If you want to send me a pre-paid shipping label for USPS, UPS, or fedex I can have it out in the mail tomorrow.

Please let us know as soon as you get new boards in stock, or if you will open a pre-order list. I need two boards w/cables.

We don't really have any stock of any thing except 36" cables right now. Also not terribly interested in a trade-in, but I have no complaints if you want to resell anywhere and undercut us. We won't have D750 stock for a while.

As for any "full combo" option, what was said is what we're thinking. I don't have a lot of available PSUs, couple dozen maybe after hosting customers get theirs, but we'll do something.

I need a Dell 750 and board combo for product dev. if you'd be interested in trading for my DPS2kBB PSU?

 Are you doing full combos now? or just the board. I need a few more setups.

 Also, would you be interested in a dell 750 trade in? I have 6 of these and the boards I am phasing out. Let me know!

On that note, we're taking inventory and gonna be sending off for the rest of parts for a batch of DPS2K boards this week. We're probably going to open up an official (pre)order queue about Wednesday, with shipping expected to start on or before October 10th (unless the PCB folks decide to ship us a week late again, grumble grumble). We'll have some PSUs available, and probably the option for a "kit" with PSU, board, and 12x 36" cables in a box with flat price including domestic shipping.
