Hey EVERYONE, I recently purchased one of those crappy eBay power supplies for like $20 USD. I did not buy this to put into a computer, I bought it to create a lab power supply. The problem is that after further INVESTIGATION, the frequency listed is 50Hz, but the input voltage is 120VAC. There is not a SINGLE COUNTRY that uses 120VAC 50Hz as its main voltages. The PSU can go between 110VAC and 220VAC, so should I just assume that they wrote that frequency specification in regards to countries that use 230VAC 50Hz, or is this a power supply that can only be used on 50Hz?It's an error in the AD. The way a computer power supply works a part from the filter components the input is connected to a bridge rectifier and filtered (large Capacitors). So the mains frequency is not reelevate within reason.    Quote from: Lisa_maree on January 07, 2021, 12:23:56 PM
