19cm PCI-E 4X to 16X Riser Extension Cable PCIe 4.0 Compatible Male to Female Adapter Riser Card Converter for Desktop GPU Graphics Card, NVMe SSD, RAID Controller and PCI Express Expansion Devices

This 19-centimeter PCI-E 4X to 16X riser extension cable is a practical hardware conversion accessory for DIY PC builders, chassis modification enthusiasts and workstation assembly. It can convert the motherboards PCI-E x4 expansion slot into a complete PCI-E x16 external interface, solving the installation limitation when the original x16 slot is blocked by large CPU coolers, oversized heatsinks or bulky add-on cards.

The ultra-thin flat ribbon cable structure greatly improves airflow inside the computer case, eliminates wiring clutter and helps lower overall hardware operating temperature. Both ends feature gold-plated PCI-E male and female sockets with tight locking buckles, which ensure reliable electrical connection, effectively resist signal attenuation and electromagnetic interference during high-speed data transmission, and prevent intermittent failures or device recognition loss due to chassis vibration.

Widely applicable to multiple expansion hardware: discrete gaming graphics cards for vertical GPU mounting, high-speed NVMe PCIe SSD expansion cards, hardware RAID array controllers, network adapters, USB expansion boards and capture cards. It supports normal operation under PCIe 3.0 and PCIe 4.0 protocols, with no driver or BIOS complicated configuration required. Just plug the 4X end into the motherboard and insert your target device into the 16X female port to finish setup instantly.

Made with durable flexible FPC flat wire and high-strength plastic connectors, the cable can withstand repeated bending and plugging without internal wire breakage. It is an essential upgrade part for compact MATX/ITX small case assembly, GPU vertical bracket installation, multi-hardware stacked expansion and professional workstation hardware layout optimization.
