Re: Learning with ATX CHIEFTEC 450W PSU
It is disabled, but as stated in the datasheet you can't be sure it has 0% duty cycle.
It is better to desolder the OVP/EN pin as that has the sole purpose of enabling the circuit.
Every power supply will be different, this only qualifies for a supply with a UCC3818N APFC controller.
Besides even if it works with APFC turned off you have no way of knowing that it will not blow up when you enable APFC, as you are not testing those components anyway.
