want to elaborate on the "550W continuous output at 50C ambient temperature". This is an extremely bold feature that puts the Neo HE 550 on the level with an elite few. Most PSU operating temperatures are in the area of 30C. This mean that when the unit is 30C it will output it's rated power, and when the temperature increases above 30C, it may not maintain it's 'rated' power ouput.
