Dual PSU

[[Viru$]]

I am using 2 power supllys few years long.

Just like written above, it is no need connect green pins both PS, you can connect (relay) green pin (Power OK/ON) and GND (black pin) to power on your power supply.

I've done this years ago. Used an old AT power supply to turn on my drives manually, then power the rest of the system after the drives are spinning. It helped my limp along, while my old 250watt atx wasn't enough to push the Athlon XP along stably.

It's posible to use parallel (redundant) power supplies so that they share the load, it's done all the time. Use a pair of diodes to connect the supply lines (the diodes must be able to hanlde the current).

Theres a caveat though, the diodes will cause a drop in voltage (about 1V to 1.6V) Usually power supplies used in this way are adjustable so that you get the correct 12V at the output of the diodes ( -=>|=- ).

PS1>------=>|=----|------->Load
PS2>------=>|=----|

This way if you have two 15A power supplies you can get 30A out of them. Use this to combine three or more PS's as needed.

that's a really cool idea , somebody should say/figure out how to voltmod the psu's voltage regulators, it probably is like video cards and stuff but harder because there are more internal designs and less people would be doing it

Edit: oh hey Hell-fire posted a guide in the other sticky in this section

Two PSU's bound together, 3,3V regulable now: http://www.madshrimps.be/vbulletin/f...-3v-psu-57961/

i never knew that this was possible good work on the thread
