Hello,

I'm looking at replacing my Ultra5 power supply with a PC fanless one.
Namely : silentmaxx FANLESS 400W

I read that this unit does NOT provide -5.0V (for old 20 pins ATX mainboard).
Does anyone knows if the Ultra 5 requires a -5.0V voltage ?

The full unit specs are:
--------------------
Connections:

    * ATX Power Connector 24pin (incl. 20pin Adapter)
    * 2x S-ATA Power
    * 1x 6pin PCI-Express
    * 2x 4pin 12V Extra Power
    * 6x 12V Drive-Power
    * 1x 12V Floppy-Power

Power 	400 Watt
+3,3 V 	30A
+5V 	28A
+12V1 	14A
+12V2 	15A
-5V 	0A
+5VStb 	2A
-12V 	0.5A
dB(A) 	0
PFC 	aktiv
ATX 12V V2.01 	yes
P4 	yes
Temperature 	-30..75°C
Volt 	230 / 115
--------------------

I already use standard "silent" ATX unit but I never paid attention to the
"-3.0V" feature... Any knowledge on that ?

TIA,
   Jo
