hi
Is your mains voltage 115 volts or 220 to 240volts?
Does the mains lead iec plug fit in the psu socket?
In usa at 115. Volts current would be 10 to 11 amps which means you need to look at markings on the cable to see if it is suitable
If 220 to 240 volts current would be about 5 amps and most mains cords would be suitable
Some very high power psu use a mains cable with a larger size iec plug and thicker mains cable
