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

[Lucky Cris]

Oh yeah, prototype PCBs for the DPS-2000BB boards came in and we've assembled a board or two for initial testing. The dummy load we're building for stress-testing is functional but not functional enough to run the boards up to capacity yet so we haven't done full testing, but should be able to this weekend.

Yay!!!

Kinda sucks when the tools you need to test the end product take more troubleshooting than the actual product... But at least when it's done we'll have a fully functional adjustable dummy load, 300A capable 3.8KW capable 24V capable, continuous-use rated, with about quarter-amp adjustment resolution, which will probably come in handy for other projects. Heck it might even turn into another product.

Oh also we're probably going to offer two versions of the DPS-2000BB board, one with and one without current monitoring. Because we have to use parts enough for at least 200A handling plus safety margins (so, 240A), the added cost of current measurement comes to about $15 per board.

As much as we don't like to offer preorders, if everything works on the test boards we might have to open up presales with a guaranteed delivery window in order to buy enough parts for a full batch. Economy of scale is a big factor so the more materials we can order at once, the better unit pricing we can get. I don't really like the idea because it's people paying for stuff they don't immediately get, but at the same time if folks don't mind tossing money in the hat for an already-existing fully-developed-and-tested product with some manufacturing lead time, then we might go ahead and do it. Opinions?

Hello.

Has anyone got a unit with sidehack? (Ideally an sp10)

The provided thread link really doesn´t tell me anything about his hosting solution.

[sidehack]

Not sure if anyone noticed, but we're running a sale on our 750W server PSU equipment. Full kits are now $55, boards are $32 apiece for any volume.

[sidehack]

Also, we're announcing a sort of preorder to raise funding for our first batch of DPS-2000BB boards if anyone wants to get in on that.

So, I know I ordered my 12 750w kits months ago as soon as they went up for sale, but I only Now powered the first one up lol. Had all the ATX power supply's I needed till now. Not disappointed! Only thing I havent done it connect the pinouts properly so the supply shuts off and powers on with the rig. seems to be causing a hang when I reboot for now.

this board (sidehack) was referenced on the KnC board as to providing hosting at $85/kwh. Can I get a link to details, please?
Thanks.

750W boards and PSU sale is still going on. 750-800W for $70 shipped or less.

I'd almost bet there is a low current voltage on the connector already representing output current.

My connector pins are nekkid in the breeze or I'd go exploring.

YMMV

[zulover]

Is the 2000watt board ready for sale and if not do we can we still have the 750 or 800 ones and how much is shipping to u.k?

[CHAOSiTEC]

how far along are the boards for the delta 2000bb? still preorder?

[sidehack]

Preorders should be caught up tomorrow, after which point we'll have some boards of standing stock. Once those are gone it'll be a couple weeks before the next batch of PCBs comes in. We've been pretty swamped lately.

since i have like 6, laying around those would come in handy when i later this year move into my new home, with alot more space for mining equipment...

what would it cost to get those send to europe? just an aproximation :-)

[sidehack]

I need to get a EU reseller. Somene asked a while ago but hasn't responded to emails. I've had a lot of people asking that question lately though.

well, how many would a reseller need to order at a time?... i might be interested in doing so...

I'm starting to build boards for HP DL 580 series PSU, and shipping from Europe is expensive for 1 or 2 boards, maybe we could find some kind of partnership.
