Dell optiplex 3020 sff

I have a Dell Optiplex 3023 SFF PC, I also have a PC case where the motherboard fits, but I don't know if my ATX psu 550w will work correctly with the motherboard, if I buy a 24 pin to 8 reduction, will the PC work normally?

thanks

yes it will.  there are two types of 24 to 8 adapter.  one kind has a voltage step up (5v to 12v) circuit wrapped in eletrical tape.  the other is passive.  Passive type has longer life span

do you know that ATX 550w psu does not physically fit SFF case.  you either have to install PSU outside case or swap case.  other than that the psu plus adapter will work
