Is the wall plug have power? Is there anyway to check that you have power coming out of the power supply. Unless you go into the case to check the power button and internal telltale lights there's no way to tell. If you replaced it with a brand new PSU then something internal probably burned it out.. Open it up and tell us what you see.
