FLEX YOUR GRAPHICS MUSCLE The Cooler Master Riser Cable PCIe 4.0 x16 Ver. 2 - 300mm comes revised for maximum flexibility and durability. High quality plastics grant increased cable flexibility and strength for the tightest PCI card installations, while the heavy-duty shielding prevents electromagnetic interference from degrading signal quality. A stainless steel PCI slot adds extra rigidity to the riser to support even the largest and heaviest graphics cards. The IPC4101D compliant PCB provides the best in class performance under high thermal loads and cable flex than any of the non-compliant competitor riser cables in the market.
