Hello, I had to replace a Compaq 340Watt power supply that fried with a 450Watt and there was no SATA power connections available. I did however have a PATA to SATA power adapter, and put that in and it works, however I am questioning why it is able to work without the 3.3 volt feed that the prior power supply had which was an orange wire.
Is there a disadvantage to running with just 5 and 12 volts without the 3.3 volt feed to the drive?
I am guessing that the 3.3 volt feed has an importance otherwise it would not have been there... so running without it has me confused?
Thanks,
Dave
