Two-port USB 3.0 add-in card for PCIe desktops
The Syba SY-PEX20124 adds two external SuperSpeed USB 3.0 ports to a desktop computer through a single-lane PCI Express 2.0 slot. It uses a NEC uPD720202 controller and supports Windows XP, 2000, 2008 and 7. The card is intended for users who need faster peripheral connections on older or expansion-limited systems.
Thermals noise and power draw in normal use
Each USB port delivers up to 900 mA at 5 V and includes a resettable fuse for over-current protection. An internal SATA power connector draws supplementary power from the system power supply to sustain the higher current demand of USB 3.0 devices. No active cooling is fitted, so the card relies on case airflow.
Build quality connectors and daily implications
The bracket provides two Type-A ports accessible at the rear of the chassis, while the onboard SATA power socket requires a spare drive power lead inside the case. Hot-swap capability allows drives or peripherals to be connected and disconnected without shutting down the host. Buyers who need internal drive bays or more than two ports should consider a different solution.

이 상품에 대한 질문
How is the SY-PEX20124 installed, and which step is often missed?
Insert the card into an available PCI Express x1 slot, then connect the internal SATA power connector from your power supply to the card; the SATA power link is the step most builders forget.
What maintenance or replacement will the SY-PEX20124 need later?
The on-board resettable fuses protect each USB port from over-current events and reset automatically, so no user-serviceable parts or scheduled replacements are required.
What limit appears first during sustained transfers on the SY-PEX20124?
The single-lane PCI Express 2.0 link caps sustained throughput at 5 Gbps, so long sequential reads or writes will hit that ceiling before the USB 3.0 ports do.
