Download the motherboard manual and it will reveal the ATX
power-on pin header. It is likely there is a jumper you
change to switch from AT to ATX power supply and it could be
important to change that jumper before trying it with the
ATX PSU. Otherwise it should only be an issue of what
you'd mentioned, the need to use the reset switch for power
switch.
