Two USB 3.0 Ports for Desktops

This PCIe expansion card adds two USB 3.0 Type-A ports to a desktop computer using a Renesas 720200 controller. It targets users who need extra high-speed connections for external drives or peripherals on systems lacking sufficient native ports. The standard PCIe x1 interface fits x1, x4, x8 or x16 slots on mainstream Windows and Linux platforms. A low-profile bracket is included for installation in slim or small-form-factor cases.

Sustained Power via SATA

The card draws auxiliary power from a SATA connector to maintain steady current delivery to attached USB devices during prolonged transfers. This design prevents the voltage drops that can occur when high-power external hard drives rely solely on slot power. The Renesas 720200 chip manages the 5 Gbps data rate consistently across both ports under continuous load. Stable operation is maintained for long backup sessions or large file moves without throttling.

SATA Power Connector Required

A free SATA power cable from the power supply is mandatory for the card to function, as the PCIe slot alone cannot supply enough current for demanding USB peripherals. Builders whose PSU lacks a spare SATA lead or who cannot route a cable to the chosen slot cannot use this adapter. The requirement is a hard constraint that determines compatibility before purchase.

Questions about this item

Does the Renesas 720200 controller run hot or draw much power during all-day transfers?

The card uses a SATA auxiliary power connector to supply steady current to connected drives, keeping the controller within normal thermal limits during sustained 5Gbps USB 3.0 traffic.

What must my desktop already have for this card to work?

A free PCIe x1, x4, x8 or x16 slot and a spare SATA power cable from the power supply for the auxiliary power input.

Will it work in an older PC that only has PCIe 2.0 slots?

Yes, the standard PCIe x1 design fits all PCIe x1/x4/x8/x16 slots and is compatible with mainstream Windows and Linux systems.
