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

Edit/ Think I've found it - http://www.watercoolinguk.co.uk/p/8-Pin-Female-PCI-Express-Power-Connector-Clear_1112.html

Actually the connector linked here is an EPS12V type for CPUs. The 8pin PCIe connector mimics the 6pin with an additional 2pin like this: http://www.ebay.com/itm/8pin-PCI-E-Female-Connector-5pcs-/281112494187?pt=Computer_Case_Mods_Stickers_Decals&hash=item41739c406b     ...and yes the pins can be joined.

Yes I see the difference now on pin 7, it is square and not tapered. However I think that is a stock pic? Either way the link you've sent me is cheaper including shipping to the UK. Thanks.

Porn?

[sidehack]

Sexy. What's your configuration? Are those loadsharing, or two Ants per supply independently? What speed are the Ants running?

Independant, 2 per supply, stock. We have 35 of my 48 running so far.

+10 for this community-mod!

+20 for it's simplicity and potential "other" use as a general 12v, high-amp power-source!

+40 for the informative tips alone...

[abracadabra]

anyone electrically isolating the case of the psu?

Porn?

Fire hazard?  

Edit/ Only kidding - looking good.

They were doing that to run two of em in series to get 24v, we need the case tied to ground for our use.
Even if ran redundant.

Got my Z750P-00's in today.  Looks like I'm going to need a bigger crate.

[ElGabo]

Sorry for the crappy picture. Made with my phone.

can anyone tell me the pinout / how to implement current share on the Z750P-00 ?


I use a bunch of them to charge my electric bike.... being able to parallel them up would be AWESOME!


I've googled my ass off but can't find anything useful :-(



p.s.... I'm assuming I can parallel a bunch of them without any problems yeah ?

That is where they isolate the PS grounds it is RC cars and planes ect, using them for charging.
Hooked in series, they build output Like a diesel truck.
The link is in this thread several places

oops, must have missed it, I'll read through again :-)

I've already got mine up and running, charging my bike at 4kw

I'd like to parallel a bunch up, so I can run at 8kw or 12kw for charging multiple bikes at once :-)


most of the time those RC guys just use these supplies for 24v or 48v to power there balancing charger, I'm charging direct to the batteries and have a BMS to sort out the balancing etc.. :-)



EDIT: current share pin is pin A2 ... so I just tie pin A2 of each parallel supply together right ?
(this is the bit I was stuck with... what to do with that pin)

Okay, so. We're officially opening sales for the Z750P boards at 6PM CST. The first batch will only have about 75 boards available, but when we have another stack about that size (in a few days) I'll update this again.

We're limiting it to ten boards per person this round, to make sure someone doesn't buy all of them.
Pricing is:
  1-5 units  -  $42.50 each
  6+ units  -  $40.00 each

We'll have some cables available, 18" 16AWG PCIe 6-pin with spades for mating to the boards' screw terminals. Cables are $3.50 apiece. I don't know how many we'll have, probably not a hundred total yet as we just got the parts in today to start generating them.

Shipping will probably be USPS Priority Medium Flat-Rate Box, unless otherwise specified and worked out with me while ordering.

Orders will be taken on a First-Come First-Serve basis; send me a PM AFTER 6PM CST with the desired number of boards and/or cables and I'll add you to the queue and work out payment details. We accept both PayPal and BTC, which the BTC price will be based off a random sampling of Coinbase's exchange rate taken sometime in the afternoon.

All order messages sent before 6PM CST according to the forum timestamp will be ignored.

There's something about the grounds I don't get yet

You do not need to know, it is needed info for the people using Remote Control RC cars and planes, they make chargers out of these and those threads started this info on jumping these PS for other uses long time ago.

SideHack saw the opportunity to use them for all crypto miners rigs ect, and he has done what is needed for your use.

If you "Want to know more" Read the RC threads just type in server power supply RC and you will find all the old info on jumping modding ect...

It is where I learned about them from.

Start here...

So grounding is for raising the voltage? But parallel doesn't matter?
