SilverStone Technology ST1500, 80 Plus Silver 1500W Fully Modular ATX/PS2 Power Supply, SST-ST1500-X

Reaching 1500W DC output (1600W peak), the Strider ST1500 is effectively at the limit of what an internal PC power supply can achieve in terms of wattage rating. For SilverStone, getting to this maximum power was only part of the goal for a consumer-level power supply so every desirable feature known were added to create a dream product. The list starts with unprecedented eight +12V rails with each capable of up to 25A and continues with features such as 100% modular cables, 80 PLUS Silver worthy efficiency ratings, and quietness level that matches most 500W PSUs.

If there is one upgrade that will likely outlast a PC enthusiasts interest in computing, the ST1500 may just be it.
