2 x PSU

[krg]

Hi

for 2 x psu's to boot together..
Its easy just get a regular 12v relay of a car etc
(splice not cut) the wire to pin 14 of the atx plug of the slave power supply (psu 2)
put the wire from the slave power supply end of the atx pin 14 to the live in (pin no: 30) side of the relay
then run a com (Earth) to (pin no : 87) on the relay...
Run a com (Earth) wire to (pin no : 85) on the relay...
then finally (splice not cut) a 12v live of the master psu ( PSU 1) atx no: 10 (yellow) wire then run this as the switch live to the relay (pin no : 86) on the switch side of the relay...
make sure you have a load on the 5v side of the psu 2 jobs a gooden..
i run 2 x psu like this and a relay for my peltiers as i run a twin phasechange system and need to hold it all off till i get the boot temps from my compressors...
