I think considering the price of that PSU new you did ok. Some of the part you could have gotten new cheap and thus had a warranty and that mobo doesn’t rate so well but hey I am not going to knock buying Gigabyte much because I have bought much of their stuff for awhile now and had no issues. How much ram did you get btw? 8 GB? 16 GB? Depending on what you in regards to that it will say even more about what kind of deal you got. Finally if you are happy that really is what matters. Enjoy.
