What this cable does

The Fervit adapter converts a motherboard's 20-pin USB 3.1 Type-E header into a standard 4-pin USB 2.0 IDC connector with a latch. It lets builders attach front-panel USB 2.0 ports or internal devices when only the newer header is available.

Speed and power limits of the USB 2.0 link

The converted connection runs at USB 2.0 rates, capped at 480 Mbps for data. Each port can draw up to 500 mA at 5 V, so devices needing more current will not operate correctly through this cable.

The 30 cm length decides fit

At 30 cm the cable reaches nearby headers but cannot span large cases or route behind motherboard trays. Builders needing a longer run or a right-angle exit will need a different solution.

Questions about this item

Should I pick a longer or shorter cable for my front-panel build?

This cable is 30cm long and designed for tight-fit applications; choose a different length only if your routing requires more or less reach.

What speed will I actually see when I plug a USB 2.0 device into this adapter?

The adapter passes USB 2.0 signals at up to 480Mbps and supplies 500mA at 5V per port, matching standard USB 2.0 performance.

Does the 20-pin Type-E header limit me to USB 3.1 speeds?

The 20-pin Type-E connector on the motherboard is used only as a physical host; the cable converts it to a 4-pin USB 2.0 interface capped at 480Mbps.
