SMUGDESK
SMUGDESK M.2 NVMe Mini PCIe to Dual PCI Riser ASM1083 USB3.0
This riser adds two legacy PCI slots to a modern board via M.2 NVMe, Mini PCIe or PCIe x1 using an ASM1083 chip and USB 3.0 power cable
- Expands one slot into two PCI ports
- Three input interfaces cover M.2 NVMe, Mini PCIe and PCIe x1
- ASM1083 chip keeps long-term operation stable
- USB 3.0 cable plus auxiliary power feed steady current
- Windows and Linux support simplifies legacy card setup
Three Input Interfaces
The SMUGDESK riser accepts M.2 NVMe, Mini PCIe and standard PCIe x1 signals so it can be fitted to a variety of modern mainboards. A single host connection is converted into two independent legacy PCI slots for older expansion cards. The ASM1083 controller manages the translation between the high-speed input and the traditional PCI bus.
ASM1083 Chip and USB 3.0 Power
The mature ASM1083 control chip provides stable long-term operation for industrial and renovation projects. An included USB 3.0 cable and auxiliary power connector deliver steady current to both PCI slots without overloading the host socket. Broad Windows and Linux support means legacy parallel, serial or SATA controllers can be installed without driver hunting.
Replaces Missing Native PCI Slots
Modern boards often lack traditional PCI connectors, leaving vintage I/O cards unusable. This riser restores that capability so parallel-port, serial-port or old SATA controller cards can serve industrial PCs and equipment upgrades. The jump is worth it when the host offers one of the three supported input interfaces and the target cards are standard PCI devices.

Questions about this item
What does the ASM1083 chip limit the dual PCI slots to in practice?
The ASM1083 chip bridges a single PCIe x1 lane into two traditional PCI slots, so both legacy cards share that one lane and operate at PCIe 1.0 speeds.
What physical space and power connections does this riser need to fit?
It plugs into an M.2 NVMe, Mini PCIe or standard PCIe x1 slot and requires the included USB 3.0 cable plus auxiliary power for stable operation.
How is the riser installed, and what step do people often miss?
Insert the card into the chosen host slot, attach the USB 3.0 cable and auxiliary power, then install legacy PCI cards; skipping the auxiliary power causes instability.
