PCIe x1 to Dual PCI Expansion Card

The RIITOP adapter converts a single PCI Express x1 slot into two 32-bit 33 MHz PCI slots. A 60 cm USB 3.0 cable links the two boards and the Asmedia 1083 chipset handles the bridge. The card draws power from a 5-pin SATA connector and fits any PCIe x1, x4, x8 or x16 slot.

Builders adding legacy PCI cards to modern boards

This card suits users who need to install older PCI sound cards, capture cards or I/O controllers in a system that only offers PCIe slots. It is not for buyers who want more PCIe lanes or who need to power devices that require a 4-pin SATA connector.

Asmedia 1083 bridge chip

The chipset provides a PCI-SIG compliant PCI Express 1.0 to PCI 2.3 bridge and supports 3.3 V, 5 V and 12 V rails at the rated currents. Windows 2000 through 10 and Linux are supported.

Questions about this item

What comes in the box and do I need to buy a SATA power cable separately?

The package includes the PCIe x1 expansion card, a 60cm USB 3.0 cable, and the dual PCI slot board. A 5-pin SATA power connector must be connected; a 4-pin SATA connector is not supported.

Which PCI Express slot widths does this adapter accept?

The card fits PCIe 1x, 4x, 8x, or 16x slots and converts the single lane into two 32-bit 33 MHz PCI slots via the Asmedia 1083 bridge chip.

What bandwidth can legacy PCI cards expect when installed through this adapter?

The bridge complies with PCIe 1.0 and PCI 2.3 standards, so each PCI slot operates at up to 32-bit 33 MHz within the single PCIe 1.0 lane provided by the host slot.
