PCIe 16X Test Card, PCI Express Slot Motherboard Diagnostic Tester with LED Light, Support Type C Power Supply and 12V DC Input for Desktop Computer Repair
Efficient Fault Diagnosis: This PCIe 16X test card is designed for quick desktop motherboard repair, automatically detecting Southbridge open or short circuits by inserting into the PCIe 16X slot to identify GPU or chip issues without manual testing.
LED Visual Indicator: Features a software-controlled circuit with multiple LED lights; pressing the switch illuminates all LEDs, with any unlit light indicating a potential open/short circuit or damaged isolation capacitor on the corresponding Southbridge pin.
Dual Power Options: Supports flexible power supply via included Type C cable or 12V DC input, and can also be powered directly through a motherboard 6P graphics card power connector for convenient operation.
Easy Operation Steps: Simply short the 24P power supply green and black wires to activate, then insert the card into the PCIe slot for immediate diagnostics, compatible with complementary kits to locate faults without a resistance card.
Wide Application: Essential for repairing motherboards that fail to boot (no display/FF code) or exhibit unstable GPU performance, effectively diagnosing display-related failures in desktop computer systems.
