Conclusion:
There's no doubt that this is the first power supply where I can conclude by saying; the Silverstone ST1500 is one power supply that will take anything you can throw at it. Not only does 1500W push the limit of what a computer power supply is capable of, but it also provides you with enough usable power to power nearly anything you can dream of. This is an expensive power supply, at nearly $400CDN, but it is worth every penny. It's 80PLUS Silver approved, has active PFC, a large array of included cables and very high all-around build quality. If you're looking to power a home super computer, then the ST1500 is exactly what you need.

Pros:
It's one of the most powerful power supplies we will see for our computers for a long time to come
Fairly quiet operation under low-load situations
Abundant amount of cables - you shouldn't worry about not being able to connect anything you dream of
Long cables are great in large cases
Included bundle makes it feel like you got your monies worth

Cons:
No master power-off switch on the back of the power supply
It's a big investment
