I am receiving the following error when trying to register my evga PSU (220-P2-0850):
"The Serial Number is not related to the part number. If you are outside North America, please check your profile under Member Home to ensure your country is set properly."
My profile is set to the United States and I am in the USA. I have had no trouble registering graphics cards. I also hope it is not a problem if this was bought a few years ago and forgot to register.
