Four SuperSpeed USB 3.0 ports

The SIIG JU-P40412-S1 adds four external USB 3.0 Type-A ports to a desktop computer through a PCI Express 2.0 slot. It uses a Renesas UPD720201 host controller and draws auxiliary power from a 15-pin SATA connector. The card supports Windows operating systems from XP through 8 and Server 2003 through 2008 R2 in both 32-bit and 64-bit editions.

Fits a full-height PCIe slot and needs SATA power

Installation requires an available full-height PCI Express expansion slot and a spare SATA power connector from the supply. The bracket measures 2.76 inches wide by 4.72 inches deep and weighs 0.12 lbs. By providing dedicated 3.0 bandwidth per port, the adapter frees up existing motherboard headers for other internal connections while adding high-speed external capacity.

Suits owners of legacy Windows desktops needing

This card is ideal for users running older supported Windows versions who require additional SuperSpeed ports for external hard disks, high-resolution webcams or surveillance cameras. Builders using operating systems newer than Windows 8 or those without a free full-height PCIe slot and SATA power connector should consider alternative solutions.

Questions about this item

What limits the sustained throughput when all four USB 3.0 ports are active?

The card uses a PCI Express 2.0 x1 link, so total bandwidth is shared across the four ports.

How much power does the card draw and does it need extra cooling when running all day?

It draws auxiliary power from a single 15-pin SATA connector; no fan or heatsink is included.

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

A free PCI Express slot and a spare SATA power connector from the power supply.
