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

[toptek]

I didn't put PCIe plugs on my boards because I don't like being limited. A good solid screw terminal, well heck you can put whatever you want on it. And cables are cheaper too. Unfortunately people really like to have things quick and easy these days, instead of good and flexible.

100% agree. With screw terminals cables are a lot cheaper. You can cut the cable the length you want. No need for flimsy molex tools to built them.

His way is good it actually stays on the board , the other screw way does suck sadly, i have one those boards and don't use it . but do use the one i bought from him from a third party, if i need the PSU that low like a S1 etc , i have one of his low end boards and I like PCEI plugs more and yes because it is fast easy sometimes fast is better sometimes it's not. , just wanted to make sure it wasn't some kind of safely issue, he knows that stuff pretty good. why i asked .


I use this http://www.amazon.com/gp/product/B007JLN93S?psc=1&redirect=true&ref_=oh_aui_detailpage_o05_s00  for 23 bucks it's not flimsy doesn't have all the bells and whistles the 100 $ + has but i also don't need a big high dollar one either . the one i linked is really good for what i need. it will do 14 weight wire even thu it says 18 in the add.

That is a pretty damn good price for a real crimper! Wonder who makes it and if they have other jaw inserts available to do terminal lugs, coax F-connectors, or RJ's?

Mine costs quite a bit more than that, but it's got a spring-loaded pin retainer and adjustable crimp depth that make things go fairly quickly, which is good when you have to make cables in batches of several hundred.

[toptek]

it might can't say i got to make my own PCIE ends for Zeus miners at the time or just to make my own PCEI cables it does them well, I had to learn how to use it the right way, i still use it from time to time but found some one that makes the cables how i want them cost is 7 or so bucks per four .

but it says it can do this and more

For use with AWG 18-22,24-30.

 it will do 14 weight wire i was able to do it once i figured how to. it doesn't feel cheap, i bought another one that was cheap for about the same price, i ended up thrashing.

For use with 4pin and 3pin Molex connectors.

Crimp tool for D-Sub and Open Barrel Connectors.

Frame is made from middle carbon hardened steel; Die made of SAE J404C Alloy Steel

Handle is rubber coated

yea i saw one of those !!! those things cost but for sure are nice if you need that , and worth it kind of .


Mine is spring loaded and adjustable but geared for single use .Im not saying mine is better or worse but it is one of the better ones you can buy at a cheap price if your using it like i do or need it.

Well, good news on the server PSU breakout board front - I have a completed final production version of my DPS8/12 board. This guy works with both the DPS800 (800/1000W) and DPS1200 (900/1200W) supplies - which also makes it HP Common Slot compatible I reckon, and should work with a decent variety of things. I've had prototypes running miners for a while, with one powering a 4.73T S7 off a DPS1200FBA for a couple months without issue.

The board has a push-button power on/off, or can take a toggle switch. It can be built with either dual 4-position #6 screw terminals per rail (like my Dell 750W board, but doubled) or 12x 6-pin PCIe jacks. It still has the 5VDC aux supply (which is optional), breaks out 3.3V standby, external-turnon and POK signals on my standard 10-pin header.

PCBs have arrived (otherwise how would I have a final version built?) but I'm still waiting on a bulk order of the PSU connectors to arrive. I do have a couple big orders lined up already which will delay the general release, but I expect any orders placed now to be going out by the end of April.

[philipma1957]

this psu is good correct?

[sidehack]

Yeah, that's the one.

Is that for the prototype board I sent you for Christmas? This final version is pretty much the same, about the same dimensions but connector spacing is a bit different and there's 2 more jacks.

Wish you'd said something. I have a few of those PSUs, and can make cables anytime.

Or did you say something and I just wasn't paying attention?

Naaah i didn't say a thing... was more or less cash-strapped (had to pay workers their end-year bonuses, etc), so when you can't walk the talk, better shut up

[sidehack]

Yeah, I hear that. Not the year-end bonuses part, I haven't had any paid minions in a long time. But I do hear the cash-strapped part. Actually, I'll probably have to borrow money to finish building this batch of PSU boards. I was hoping not to, but one of my anchor customers evaporated so I had to out-of-pocket a substantial amount of the initial cost without any preparation. I'm working out a plan on how to pull it off, but there's two things I really hate - borrowing money, and relying on other people to help. I don't like borrowing because of the inherent risk I somehow can't pay it back, in which case I end up hosing good people. And I don't like relying on others because, at least half the time, I'm disappointed (for reference, see the thing I just said about an anchor customer disappearing).

But this board is a good product. It'll sell. And if I can bring in enough capital to build the whole batch, I can supply my anchors and actually have a substantial standing stock for the first time in a long time, which means being able to meet immediate orders without lead time, which is good for everyone involved.

[philipma1957]

Yeah, that's the one.

so I ordered this one today.

  I can use one of your boards when you get  chance.   thanks phil

[sidehack]

Cool. Maybe I'll send it with a DPS800 (I've got about a dozen of 'em running around) so you can test out the dual use.

sounds good I will run a thread on those 2

[kipper01]

I guess I need to see what type of server power supplies they toss in the eLoop bin at work.     Probably some good stuff.

+1 Nice.
I'll have to look into the DPS-1520. I assume it's a 1500w supply? If so and if priced like the HP-CS 1200w supplies then it'd make a perfect fit for s7's and s9's.
