You should get a brand power supply (Enermax, Seasonic, BeQuiet, Antec, Coolermaster, Tagan...) because they have security mechanisms like short-circuit protection, overvolting protection etc and they are also much more efficient compared to cheap noname PSUs. Also: You should really listen to bastinator. Because if you really going to spend 1000€ for your new PC, you should get MUCH better parts.
