Vszerda PCI-E X16 164-Pin Adapter Card

PCI-E X16 adapter for GPU testing

The Vszerda PCI-E X16 adapter card sits between a graphics card and the motherboard slot to protect the GPU's gold fingers from wear during repeated insertion and removal. It is aimed at technicians and builders who frequently swap or test graphics cards and want to preserve the card's edge connector. The adapter uses a 164-pin gold-finger plug on one side and a matching PCI-E X16 slot on the other. It ships as a single adapter card in the package.

Four-layer PCB with anti-voltage buffer

The adapter employs a four-layer circuit board with high-frequency resistance and an anti-voltage buffer on the PCI-E X16 gold fingers to improve safety when the card is unplugged while powered. Gold-plated contacts on both the PCB fingers and the slot tabs provide oxidation resistance and stable electrical connection across many mating cycles. Users must disconnect the power supply before inserting or removing the adapter to avoid damage.

Extends slot life for repeated test cycles

By absorbing the physical insertions, the adapter lets the motherboard's primary PCI-E X16 slot and the graphics card's edge connector avoid the mechanical stress of frequent swaps. It comfortably handles daily test-bench workflows where cards are changed multiple times per session. The adapter does not add extra bandwidth or signaling; it simply passes the existing X16 connection through while shielding the original contacts.
