The Radeon X1800 XT board is somewhat of a behemoth. The PCB itself stands at 228mm long, which is some 41mm longer than the Radeon X850. The primary contributing factor to the different sizes is the power regulation circuitry that is on the back of the X1800 board. With a fairly large die running at 625MHz and 512MB of GDDR3 RAM running at 750MHz, a clean supply of power is certainly going to be critical to the operation of the board - unsurprisingly the board features an extra PCI Express for graphics power connector that augments the 75W supply from the PCI Express x16 slot directly from the PC's power supply.
