1. This FebSmart VER006C is a PCIE X1 to PCIE X16 GPU riser. The GPU riser will extend motherboard PCIE X1 slot out and covert PCIE X1 slot to PCIE X16 slot. The extended PCIE X16 slot will provide safe and reliable connection with GPUs. Light up more GPUs in Ethereum Mining rigs or other GPU Mining Rigs for currency mining. | 2. This GPU riser will extend the motherboard PCIE X1 slot out and covert the PCIE X1 slot to PCIE X16 slot, users will have more room to place more PCIE X16 GPUs and cool down GPUs tamperature. Added fixed buckle on the extended PCIE X16 slot, will ensure GPUs always online, always works in high performance. | 3. Designed with 3X solid capacitors, 1X voltage transformer and 1X inductance on GPU Riser, will make sure PCIE data signal get stable and reliable power supply. Built in electric safty fuse, will keep PCIE data signal away from overvoltage, overcurrent. Communicate with Ethereum mining pool instantly, Ensure Ethereum Miner Rigs get more Ethereum Hash Rate. | 4. Packed with 23.6-inch USB 3.0 extension cable, will make sure GPUs flexible connection, easy to place GPUs in more room. Comes with 7.9-inch 15Pin SATA to 6Pin molex power cable, allow users easy pick-up basic PCIE data signal power supply from GPU Miner Rigs PSU. | 5. ATENNTION: The GPU riser may can not provide enough power for some heavy GPUs when the 6Pin to 15Pin SATA power cable is the only power supply. Users MUST PLUG the 6+2 Pin power supply on the GPUs, pick up power from PSU (power supply unit) directly. In this case users can remove the PCIE riser 6Pin to 15Pin SATA power cable. | 6. WARNNING: 1. GPU Risers will work with GPUs Miner Rigs 7X 24hours, it is consumables, provide 30 days warranty ONLY. 2. If the PCIE X1 interface connector inserted REVERSELY on motherboard PCIE slot, will damage the connected GPUs or PCIE slot. FebSmart do not responsible to these incorrect using damage.
