Well I just got my PSU in the mail today and I opened it up and was like "Hmm something seems to be missing." After a few seconds I realize there is no power cord. I open the paperwork that came with it and it says "Note: No power cord included. By reusing your existing cord, you can reduce waste and help protect the environment." Umm okay. Anyways I was like well I can just buy one on newegg or something. Well after looking I don't know what the hell to buy. Some are $4 and some are like $40. I don't know what to look for and all that. And I know someone will just post a link and say buy this one. Thats cool but please tell me why and explain the differences between cords. Thank you much in advance.
