All power supplies are 230 volts, because that's what the voltage the electricity comes to your house! You need to list all the other specs: wattage and amperage, and the brand of the power supply.
Well they aren't ALL. different countries you know LOL. but good catch I was trying to decipher what pcie 230 was and gave up.
I should've said most.. I guess it's only america that has 115 volts?
