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

Yep. Isolating the circuit ground from case ground/neutral means you can stack the voltages together by referencing one supply's ground to another supply's (isolated) 12V output, so measuring between one ground and the other's 12V gives you 24V without exploding anything. If you're just paralleling you can tie the Current Share pins together and the supplies will cross-regulate to balance the current outputs evenly between several supplies, so you can get 12V stupidly-high-current without exploding anything.

can you explain that a bit more?

[sidehack]

Not really. Someone already posted where the current share pin was on the supply, and it's also broken out to a header pin on my board. If you want to parallel multiple supplies, as far as I know all that is required is to put them on a common bus (hook the ground and 12V together) and then tie the current share pins together. The rest is internal, it should "just work".

One more tidbit for those wishing to do some more research.
They are also designed to be hot swappable in a redundant setup, with sidehacks plugings you can get that to work also, as the design is in the gold fingers length on the power plane, to be able to pull and plug without arcing, it will not power up till the new supplys power fingers are engaged. Or arc on removal, power good pin will disengage first..
You could really take the larger supplies "to the max" if wanted, 100s of amps 5000w systems possible. @12v

Payment sent, sidehack!  Lemme know if you need any more info.

Thanks again.

What is everyone's solution to cool the huge Delta DPS models like the 1500 and 2000?  Some turbine props pushing tons of CFM?

Kudos! Thanks man.

I'm going to close orders for now. We've made a good pile of cables this weekend, but will be probably the rest of the week filling the current orders. Taking time to make cables has slowed board manufacture a bit but that should be up to speed soon regardless of cable time.

In any case, if you've placed an order already it'll ship before the end of the week (you will have been told about this delay due to cable stock while placing the order); no further orders will be accepted until the current ones are filled and stock is built back up. Probably in about a week.

Four fans, taped two to each side. I was using cheaper case fans, but they would still overheat when I really pushed them (12 gpus per 2000w supply )  I'm now upgrading to some more powerful delta fans, at least on a few of them. This should only take one or two per pair of PSUs.

Thanks for the update!  So if we paid already, we're in the first grouping yes?

[sidehack]

Yes. I have a few orders placed that haven't paid yet, and anyone that has paid already, are in the first group and your order will ship as soon as all stock is available. If you only ordered boards, it should be immediate; orders with cables will be shipped as the supply is made available.

That's great.  Yeah you warned me at least when I was PMing you that any order with cables would delay it until the end of the week.

That's still fine with me.  Thanks again!

I am ready to pay the second you have cables for my 6 boards.
Do you still plan to have them in the next day or so??

[LuxCapacitor]

Got mine yesterday.. They look great!  Packaging and included instructions seem top notch.  Going to test them out this evening 

[BotwinBG]

Hey, how is my order doing? I never received any confirmation...

[Unacceptable]

How do I go about ordering a few boards   I PM'ed sidehack,no response....yet......... 

Also what AWG is best for Antminers   


Thanks!!!!!!!!!

I just shipped the last boards we had ready to roll. We're gonna finish out the run before opening orders again. It'll be at least a week, maybe more.

Thanks for replying  

I can wait,not gonna need em for at least 2 weeks anyhow  

Doh...just saw a link in your sig    That where we order from later
