"Whether you want to recognize it or not, power supplies are an integral part of your computer. And it's not just about wattage -- if you don't have a quality power supply that delivers, your latest quad core, pair of graphics card, and half a dozen of hard drives won't run stably. And then you would end up blaming that on the OS or whatever. On the other hand, most people with relative high end configurations probably won't even need 1200W power supplies anyway -- my Core 2 Extreme QX9650 and 8800GTS G92 (Plus all the relatively high end components) needed no more than a quality, efficient, high performance power supply that delivers what it's rated for. I used to run my computer off a Seasonic M12 500W. That was my first Seasonic power supply that impressed me throughly in both performance, efficiency, and silence. When Seasonic released the M12II, it didn't take me too long before I got one and installed it to see what kind of improvements they had made to it, in order to make it an even better power supply. With relatively modest power ratings by today's standards of only up to 500W, how will this power supply accomplish its tasks with the latest configurations? Although we won't directly test performance, as we don't have professional load testers and for the fact that this is only a product report -- we'll take a look at what kind of internal components it takes off with."
