It sure is an ATX. The probem is that the 5 spronged standard power
cables that you plug into harddrives and CD-ROMs before we had SATA only
has two phases where as the power to the SATA drives have 3. There's 4
cables for a standard cable, and 5 for a SATA power cable. So unless you
have an active adapter that does somekind of transformation of the power
to get to the 5.5 volts that is missing, I don't know what that adapter

Power for the CPU? I'm a bit lost there. There should be none except for
the FAN and a special one for the PCI-E I think it is. The rest goes tot
he mobo and peripheries. But yes, I've been down that road too in the
past. I do remember when ATX came out and there was no way with the old
one to connect to a modern mobo. And then you have special case plugs
too etc. *sigh*.
Anyway - my current ATX power supply only provides two phases on the
Molex 8981 Power connector that is pretty standard (wiki says it's a 30
year old standard by now) - 12 and 5 volts. It's missing the 3.3volts
needed by the SATA power plug.
I think I wrote 5.5 was the additional voltage. It was 3.3 volts.
Standard power is 12 and 5 volts.
But I'm very much interested in seeing how you got it to work. If you
have a link to the adapter you used I'll check it out.
Wise words of the day:
oh okay. my mistake.
