PAXX- S single PCI Express 3.0 x16 riser card adapter. A new product of RAIJINTEK for DIY computer accessory and it almost can be using in any tower chassis (without Mini-ITX chassis). This is where the practical extender cable comes in and allows the installation of a PCI Express slot with an x16 connection on the motherboard by allowing an additional PCI Express x16 slot to be positioned strategically on or off the chassis. This x16 slot is electrically connected with full 16 data lines, providing the full bandwidth for graphics cards. A flexible flat-ribbon cable with a length of 200 mm and High Speed Shield is used for data transmission, which allows a lot of room for the installation of the PCIe slot. Even with modding projects or in differing cases, it may be necessary or useful to place PCI Express expansion cards in unusual places. PAXX-S is easier to position graphics cards parallel to the mainboard.
