EXSYS EX-1020 Compact PCIe Expansion Box: 2x PCI & 2x PCIe Slots

Expand the capabilities of a small form factor PC or server with the EXSYS EX-1020, a compact external expansion box that adds two PCI and two PCIe slots through a single PCIe x1 host connection. Ideal for system integrators and IT professionals who need to install legacy PCI cards or additional PCIe cards in space-constrained environments.

Key specifications

• Host interface: PCIe x1 (PCI Express 1.0a)
• Expansion slots: 2x PCI (32-bit/33MHz), 2x PCIe x1 (PCI Express 1.0a)
• Chipset: PLX PEX 8112 (PCIe-to-PCI Bridge), ASMedia ASM1083 (PCIe-to-PCIe Bridge)
• Power supply: External 12V/3A DC adapter, 36W total output
• Slot power: PCI up to 5V/2A (10W), PCIe up to 12V/1A (12W)
• Cable: 1 meter PCIe x1 expansion cable
• Compatibility: Windows (XP/Vista/7/8/10/11, Server 2003-2022), Linux
• Form factor: External desktop box with metal casing
• LED indicators: Power, activity
• Plug & Play, hot-plug support for PCIe slots

Why choose it

The EX-1020 provides a reliable way to use full-height PCI and PCIe cards with systems that lack internal expansion slots, such as mini-ITX or embedded computers. The metal housing ensures durability, and the external power adapter delivers stable power to all four slots.

Ideal use cases

• Adding legacy PCI cards (e.g., serial, parallel, or data acquisition) to modern PCs
• Expanding PCIe connectivity for network cards, storage controllers, or video capture cards
• Industrial and test environments where hot-plug capability is needed

Good to know

The box connects via a single PCIe x1 cable, so the host system must have an available PCIe x1 slot (or larger) for the host adapter. The PCIe slots support hot-plug, allowing cards to be swapped without powering down the entire system.
