Two-port USB 3.0 PCIe add-in card

The sakose BT-PEU310 installs into a PCI Express 2.0 x1 slot and provides two external USB 3.0 Type-A ports. It is built around the NEC uPD720200 chipset and supports data rates up to 5.0 Gbps. The card targets desktop owners who need extra SuperSpeed ports for external drives or peripherals.

Backwards compatibility with older USB gear

The ports accept USB 1.0, 1.1 and 2.0 devices, so legacy keyboards, mice and flash drives continue to work without adapters. Operating system support covers Windows XP, 2003 Server, Vista, 2008 Server and 7. No additional software bundle is mentioned in the specifications.

Low-profile bracket and single-lane design

A single-lane PCIe 2.0 connector keeps the card compatible with short slots and small form-factor cases. The two Type-A ports sit on a standard bracket for direct rear-panel access. No external power connector is required, simplifying installation in compact builds.

Questions about this item

Will the NEC uPD720200 chipset on this card need a firmware update or driver reinstall after a Windows upgrade?

The card uses the NEC uPD720200 chipset with native driver support in Windows 7 and earlier; newer Windows versions may require a manual driver install from the chipset vendor.

What throughput limit appears first when both USB 3.0 ports run at 5.0 Gbps simultaneously?

The single PCI Express 2.0 x1 lane caps combined bandwidth at 5.0 Gbps, so simultaneous full-speed transfers on both ports will share that ceiling.

How much extra heat or power draw should I expect from the BT-PEU310 during all-day file transfers?

The card draws power only from the PCIe slot with no external connector, so added heat and power use stay minimal during sustained transfers.
