You can hardly hear the psu running and it was very easy for me to upgrade from my old 650w psu to this. I upgraded because i got a second gpu for sli gaming and it came with all the new cords that i needed. It didnt come with an sli bridge like my old 650w psu did but that wasnt really an issue because i just bought one separately. I love evga products because they seem to handle any amount of abuse for years and never seem to slow down at all. I would absolutely buy one again if needed.
