Our low-end system configuration, consisting of a low-end dual-core processor and a GeForce 7600 GS graphics card, only consumes about 185W of power at maximum load levels. As we can see throughout the graphs at various load points, our Corsair VX450W unit is consuming the least amount of power from the wall, which reflects in a positive manner on this new unit. This shows that at all of the load points we tested (which in this case are all fairly low), the VX450W is more efficient than its peers.
