"With the recent onslaught of 1000-watt and higher power supplies from various manufacturers, it is nice to see that many still take the time to cater to the PC enthusiasts that demand quality power, maybe just not so much of it. Sure, a 1000+ watt power supply may power just about anything a power-user can throw at it, many times this amount of power is just plain over-kill. If you aren't running top-of-the-line video cards in a linked configuration, quad-core processors and terabytes of hard drive space, a power supply of 600-watt proportions may be more up your alley. If that is the case, then the 600-watt version from the Ultra Products X3 line may be just what you are looking for."
