EVGA has launched one of the most expensive desktop motherboards in the world, the EVGA X58 SLI Classified motherboard costs a whopping $449.99. For that price you get a LGA1366 motherboard with 3-way SLI + PhysX + 1x PCIe device on a single board, 2 8pin +12V connectors capable of delivering 600 watts of power, 10 phase Digital PWM with a switching frequency of up to 1333KHz, three times the amount of normal gold content in the CPU socket and much, much more. Full specs can be found at this page.
“Many Manufacturers are stuffing the CPU Core Power Circuitry with endless phases without looking at the big picture. We take a very first to very last approach instead.” said Peter “Shamino” Tan, Overclocking Evangelist for EVGA. “First the +12v comes into the board through the 8 pin CPU Power Connector. We remove the bottleneck here by doubling the current input capability with dual +12v. Next, the +12v is processed through a beefy 10 phase Digital PWM with a switching frequency of up to 1,333KHz, twice the speed of typical Digital PWMs and three times the speed of typical Analogue! Furthermore, you can adjust the switching frequency through the BIOS from 800KHz to 1,333KHz, deciding between power efficiency and heavy overclocking or benching.
“Next, a super-low ESR and ESL film capacitor placed right behind the CPU socket ensures the cleanest power goes into your CPU. This finally passes on to a high quality CPU socket with three times the normal amount of gold content for the lowest impedance and highest current transfer, and of course, the socket is anodized a slick shiny black!”
