    Power supply is an Astec HPS3KW. 48 volt, 3000 watt. I found documentation easily and can power up the units. They are "Single Wire Parallel" but I cannot find which pin it is supposed to be. The doc has the pinouts but does not state what the pinout acronyms are, "PWOK", "SCL" and so on.

    FYI, Single wire parallel = current share multiple units.

    I dont know what more I can add. Could use this solution ASAP. There will be that one pin (current share) that will hook to the same pin on the other unit so I can get all the amps from both units. Most jobs wont even use more than 40 amps but I have one lasercutting job waiting that needs a lot of power, about 80 amps. I have a lot of Astec experience and its strange that the documentation is not clear about it. Thanks in advance,

SOURCE: I need to power up

You must tie both PSON and PSKI to GND (=5VRTN) then it works.

You have to "short" two of the sockets.
Get the CORRECT two, or else you could kill yourself, or "fry" the power-supply.
Details: http://pcsupport.about.com/od/insidethepc/a/atx-pinout-24-pin-12v-psu.htm about the "pin-out" arrangement.

It would be easier/safer to connect the sockets to a motherboard, and connect a power-switch to the ON/OFF pins on the motherboard, and then use that power-switch.

If your power supply is rated 6 AMPS and your motor is rated 14 amps peek, then when that motor starts it will draw the 14 AMPS, That will trip the power supply right then and there. After it runs a few seconds the AMPS will drop about ½ that, but still 7 AMPS is more then the power supply is rated, so you will need a different power supply.

You can jumper on an ATX power supply by using a wire to connect pin 4 (green wire) to any of the grounds on the 20 pin ATX connector. The grounds are normally a black wire. You will need to put some sort of load on the power supply such as a hard drive to keep it running.
