I finally picked up a few of these beasts...

IBM 2980W Power Supply
IBM p/n 39Y7414
Model DPS-2980AB A

I know many use this mega power supply, I'm guessing many are using the "break out board" to get the voltage out.

I'm --NOT-- looking for the breakout board - I would like to HARDWIRE and not have friction contacts carrying the amperage.

I'm looking for the pin out / connection diagram / pin description etc.

**** More Specifically, what pin is the +5VDC and what pin turns on the power supply? I've been using DPS-1200FB power supplies where a resistor between two pads turns on the power supply so I'm assuming that this power supply has something similar to turn it on.

I did a search on the forum and a quickie Google, but I have not found what I'm looking for. Maybe I'm using the wrong terminology or being too specific in my searches. Who knows.

So, if someone has this information, could you post it?

Thank you

Here is the answer - posted to you in the s9 thread also:

https://bitcointalk.org/index.php?topic=1007440.0

But you simply don't have enough space to solder all wires to the PSU, you would need to build your own fanout connector.  And I would def make sure to use all 6+ and 6- connectors so you don't melt down the PSU's connections!


(for reference I Google'd   IBM 2880W pinout site:bitcointalk.org  and it was the 8th result down titled "Help starting an IBM 2900W PSU - Bitcointalk" )

They use the same pinouts as the 2880W PSU's, the breakout boards work the same on both models (with the exception of mounting points for board supports on the 2980's being different).  What miners will you be powering, and is there a particular reason you are trying to stay away from friction contacts, considering they are used in industry in that manner without problem?  A friend of mine on here Soab did the same thing with access to the right equipment, and decided that the breakout boards were the better route.  I've since sold many to him over the years.

Here are some pics of how we made the harness. My buddy owns a cable manufacturing company and even using $120,000 of equipment, the time and effort was not worth it. I only made these because of the delivery time to get J4bberwock boards for the first 52 Antminer S5's. I highly recommend not even consider doing harnesses and just buy the boards.

The equipment we used  to do this project was an auto feed wire cutting and stripping machine that did all the 10 gauge black and reds. Then we used  an automatic stripping machine to get .6" on the pre-made PCIE wires we got from klondike_bar. An ultrasonic welder was use to join the wires. Had to use a 150 watt soldering iron to join the welded pads to the power supply.

There is also a shot of the power meter when the room was hot and the fans were at max, it was drawing 3785 watts.
