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'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!

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

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.

Just found a DPS-2000BB on ebay!! gonna get it but what adapter peace fits on it

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.

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?

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

Yup, they are 12A @ 200-240

I'm gonna be spending tomorrow on some much-needed devtime for DPS-2000 boards

quick question, I think these DPS-2000 may only support 200v~240V so are they are they any use for most clients running 110~120v ?
correct me if im wrong

That's funny, most people call me a jerk. In my defense, I'm an equal-opportunity jerk. I hate all people equally. Unless you're intelligent and hard-working, in which case you're probably okay. Unfortunately people like that are the minority these days, especially in the US.

That's probably the very reason I like you then! I place a high value on the same things and find them in all too short supply these days as well.

I just received the other day, our shipment of Batch 2 PCBs. These are V0.5, improved slightly from the V0.4 boards we've shipped already - they'll fit a better connector, have a more accurate current measurement, and you'll actually be able to read the various pinout labels. They should also fix some issues that increased assembly time, so hopefully they'll start rolling out quicker. I'm gonna be spending tomorrow on some much-needed devtime for DPS-2000 boards, but probably won't have any direct progress on anything for a few days due to other commitments. If days were more than 24 hours long I could work for more than 14 of them - and my minions could work for more than one of them - and we'd get you guys more good stuff faster. But there's only so much one guy and his mediocre help can accomplish at a time.

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.

Dude I think I love you. Cheesy

You tell 'em sidehack!

You people should give sidehack mad props. This is a great project he's started, he puts out a quality product - even with the occasional ugly solders! Wink

- and he's honest, straightforward, and professional. He obviously puts forth the effort to do things well, and the results are really beneficial to a community like this one.

until I can whip some minions into shape and convince them that an hour's work every five days is not acceptable progress.

If I weren't so involved in my own things in life I think I'd love working with you.

Cables are currently in low stock, until I can whip some minions into shape and convince them that an hour's work every five days is not acceptable progress. Stock is growing on D750 boards, and parts are inbound for the next batch so general sales should be open soon. I'll probably post the sales thread in the Group Buys forum, as that's more the proper place for such things.

Do you need help with that?

Eagerly awaiting the next batch, I presume you'll add a post in here directing to the group buy thread when available, I don't keep up with that forum and don't want to miss them.

I've been getting a lot of PMs lately from people saying "I read your thread about the server supply boards. What supplies are you building boards for and how can I preorder?"

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. And I do not take preorders.

Was that on a board directly, or risers? I've got two machines running with GPUs slotted into the board directly, with the boards EON wired to the ATX supply, and both are fully functional.

All the cards were on risers. Will assemble another rig sometime during the week and test again.

BotwinBG - did you manually power up the supply, or have the EON linked to the ATX? How was it set up?

t7ank - I dunno. Those numbers are what the PCIe standard dictates. It's definitely possible to pull more power, just means it's not standard compliant. Also 75+75+150=300.

It was a test setup, I was assembling the OpenRig.com frame I got (fucking finally). Two 280x connected to a regular ATX PSU, both on molex and on 6pin. Two 280x connected to the Z750P via 6pin and to the regular ATX PSU via molex. I manually powered the Z750P prior to powering up the rest of the rig. The 280x connected to Z750P did strangely enough spin up on rig shutdown, fans came one for a second or two. Nothing else. I needed that rig online and hashing at that moment, so I did not try anything else.

Thanks for the boards Sidehack.

They work great. I am running 7 BTCgarden blades with them and few fans.

Thanks again for great product and quick shipping.

On GPUs, only 2 of the pins are used for 12V power so that's 18A per connector. But on GPUs only 75W comes in per 6-pin, which is only 3.1A per pin. If you adapt 6 pin to 8 pin, you use all 3 lines but for 150W, so 4.2A per pin.

Stupid.
Then reply how can 4870x2 pull 426W from PSU, if it only has 6pin + 8pin (meaning 75W from MB + 75W from 6pin + 150W from 8pin equals 350W)
6pin are 8pin are RATED for 75W and 150W, but they supply much more to GPUs.

Anyway i found better molex pci-e crimps, that are declared for 13A per pin, but still play safe.
