"their Booster X3 is the first in a new class of PSU designed to fit into a spare 5.25" drive bay and provide power only to your graphics subsystem. Using a 'best tool for the job' approach, the Booster X3 is able to provide 300W (320W peak, under load) output power to your graphics hardware, for up to two cards.

The basic principle for both user classes is simple. If you're a very high-end user, even with a high-end current power supply, why not augment the Booster X3 and take the GPU load away from what you have already, hopefully resulting in better supply to your graphics subsystem and the rest of your workstation."
