30/60/100CM USB3.0 PCIe Riser Card, PCI Express 1X to 16X GPU Extender Adapter with 4Pin Molex Power Port for Graphics Card Mining Rig Expansion

This PCIe 1X to 16X riser adapter is designed for multi-GPU mining rigs and desktop hardware expansion, equipped with detachable USB3.0 data cables in three optional lengths: 30cm, 60cm and 100cm to meet different rack and chassis layout demands. It separates data transmission and power supply circuits to greatly lower electromagnetic interference between multiple graphics cards.

Built with an independent 4Pin IDE Molex power input, the riser draws power directly from the PC power supply instead of relying solely on the motherboard slot, effectively solving power shortage problems that lead to GPU unrecognition, black screen or automatic shutdown under full load. Multiple filter capacitors on the PCB stabilize voltage output and suppress voltage drop during continuous heavy-duty mining or rendering work.

The high-flexibility USB3.0 cable allows users to space each graphics card apart in open mining frames, improving GPU heat dissipation and preventing overheating performance degradation. Lockable PCIe slot and gold-plated anti-oxidation pins guarantee tight connection without intermittent signal loss. Plug-and-play design supports all mainstream Windows and Linux systems, no extra driver installation needed.

Compatible with all standard PCIe 1X/4X/8X/16X motherboard slots and NVIDIA & AMD desktop graphics cards. It is a cost-effective essential accessory for mining rig assembly, workstation multi-GPU setup, compact case space optimization and DIY PC hardware upgrades.
