Hello friends, as I am using computer and I want to test the Power Supply Unit (PSU) of the computer, as I want to check the working of the power supply unit as I am using a Corsair HX850W PSU. But I am only one computer and do not have spare computer to test the power supply unit. The main aim of the testing is that I want to test that it powers up or not, so if it do then I can simply plug it with a kettle lead, if I do it then does it will cause any damage to the computer? So please give me your suggestion and tell me that I can do it or not. Thank you.
