Unfortunately, the addition of a 80 mm fan does not prevent from startup failures.
Furthermore, the failure occurs either after a long power off period or soon after a shutdown.
Anyway, the loads of my configuration seem to be over the requirements if they can be considered as a whole.
My devices are allocated as follow :
~On one rail is attached :
CD-ROM : 5V 1.7A 12V 1A (I don't know how the selection occurs)
CPU fan : 0.90A
80 mm fan : 0.15A
Temperatures display : ?
~On a second rail :
HDD Seagate Medalist : Startup : 12v (peak) 2.2A 5v (RMS) 0.6A Seek 0.5 A ...
~On a third rail (SATA) :
HDD Raptor : 12v : 12v 0.75A 5v 0.90A startup ???
The specifications chart of my PSU shows :

Output Voltage /Min. load /Max. load /Load Reg. /Ripple & Noise
+3.3V /0.5A /30A /+5% /50mV P-P
+5V /1.0A /28A /+5% /50mV P-P
+12V1DC /1.0A /14A /+5% /120mV P-P
+12V2DC /1.0A /15A /+5% /120mV P-P
-12V /0.0A /0.5A /+10% /120mV P-P
+5Vsb /0.0A /2.0A /+5% /50mV P-P
I don't know what mean +12V1
DC and +12V2
DC, because, if I don't make mistake, that doesn't refer to the rails, as the PSU has more than two and "Molex" seem to provide either 12V or 5V.
I don't understand how the voltages are dispatched among the rails.
Is of any hope to dispatch my devices among the rails in a better load balanced manner ?
(Difficult, for space and cables lengths considerations, but if it is helpful I will try it).
