PCIe to PCI Adapter Card - Legacy Device Expansion with USB 3.0 Riser

In this review of the PCIe to PCI Adapter Card from Trotwei Blue, the bottom line is practical: this adapter is for anyone who needs to run older PCI sound cards, capture cards or other legacy PCI devices in a modern motherboard with only PCIe slots. The single biggest reason to buy is its combination of a plated PCI slot and a 60cm, 90 angle USB riser that allows the card to sit outside a cramped chassis, solving clearance and blocked slot problems without complicated case mods.

Key Features

• PCIe to PCI conversion: Provides a native PCI interface so legacy audio interfaces, capture cards and other PCI devices can be used on modern systems.
• External placement via USB riser: The included 60cm 90 angle USB cable lets the PCI card sit outside the chassis when internal space is limited.
• Wide motherboard support: Works in PCIe x1, x4, x8 and x16 slots to give flexibility across many motherboard layouts.
• ASM1083 chipset: Uses the ASMedia ASM1083 to improve compatibility and stability with a range of PCI cards.
• Specialized cable required: The riser cable is specially customized and must not be swapped for a generic USB 3.0 cable to avoid damage.

Who It's For

This adapter is aimed at hobbyists, audio professionals and content creators who rely on older PCI capture cards or sound cards and need a simple way to connect them to modern motherboards. It suits PC builders who run limited-case builds or test benches where internal clearance is an issue and an external riser is the most practical solution.

Those who should look elsewhere include users wanting plug-and-play PCIe devices that already have native PCIe versions, or anyone unwilling to accept the specialized cable requirement and installation care needed to avoid incorrect insertion. It is not a substitute for a native PCIe card when performance or bandwidth is a primary concern.

Pros & Cons

Pros

• Enables legacy PCI device use on modern motherboards without a PCI slot.
• External 60cm riser cable resolves cramped chassis and blocked slot issues during installation.
• ASMedia ASM1083 chip improves compatibility and stability with a variety of PCI cards.
• Reported by customers to work well out of the box and to have good card build quality.

Cons

• Requires the specially customized USB cable and warns against using a standard USB 3.0 cable, which adds a handling limitation.
• Not a performance upgrade over native PCIe devices and depends on correct card orientation during installation.

Frequently Asked Questions

Can I use a regular USB 3.0 cable instead of the supplied riser?
The riser cable is specially customized and should not be replaced with a standard USB 3.0 cable to avoid damaging the adapter or motherboard.

Which motherboard slots work with this adapter?
It is compatible with PCIe x1, x4, x8 and x16 slots on the motherboard.

Will this improve performance of my PCI device?
This adapter enables compatibility and physical placement but does not increase device performance beyond the card's native capabilities.
