|First of all, why do you think you need 100W?|
Antec normally has been a good brand. However, in this case they are out and out lying about the output potential.
V x A = W. Using that formula the rail outputs add up to 2127.5W. Obviously way more than the 100Ws claimed. This means they are fudging the actual capabilities. Look at the input ratings.
13A @115V = 1495W potential output @ 100%. Nothing is 100%.
In short, look elsewhere.
Post what graphics card/ cards and what CPU, you intend to use so we can recommend what wattage PSU you actually need.
