The PRC01 expansion kit consists of a PCIe riser card and two adapter cables. Installing this accessory in the Shuttle XPC slim XH510G2 allows for a second external power adapter to be connected, enabling the use of more powerful graphics cards. By default, graphics cards with a maximum power dissipation of up to 75 watts can be supplied via the PCIe slot. With PRC01, the graphics card can be supplied with additional power via an internal 6- or 8-pin power connector. Note: The second power adapter is not included with PRC01.
