Introduction

It seems every major manufacturer has been releasing 1kw+ power supplies recently and while it seems insane that anyone would need such a monster unit to power their system, they are necessary for high end servers, multi-GPU systems and for hard core overclockers.

Today we will take a look at a very powerful PSU from Silverstone, the Decathlon 1200W. Silverstone have taken the core of a slightly older server-oriented Olympia 1200W PSU, and have re-designed it to suit the requirements of hardcore enthusiasts, thus the 1200W Decathlon was born. Silverstone are renowned among for building products to the highest standards, so with that in mind let us see if the 1200W Decathlon can deliver the goods.

While the artwork on the box is minimal, there is a wealth of data about the units performance and features, as well as many of the components Silverstone used to create the PSU. It is a thick and sturdy cardboard box which makes it secure and Silverstone have packaged everything inside very securely. There is a very well written and detailed manual with a wealth of information about the unit, a bag to store any cables you won’t attach to the unit, two extra 8-pin PCIe cables and a thicker AC power cable.
