  • 3M adhesive backing secures cable to chassis or motherboard
  • circuit-prevention outlet design protects pins from accidental shorts
  • Works with 9-pin USB 2.0 headers on Windows, Linux and Mac systems

What this cable does

The ETopSell 9 Pin 2 in 1 Internal USB Splitter Cable turns one motherboard USB 2.0 header into two female ports. It suits builders who need extra internal connections for DIY light bars, PWM fans or other 9-pin USB 2.0 devices. The 30 cm length fits typical chassis layouts. A 3M adhesive strip on the back secures the PCB to the motherboard or case.

Thermals noise and power

Wire-belt shielding and a short-circuit-prevention outlet design protect the header pins from accidental shorts. The splitter draws power directly from the motherboard header; total current for both downstream devices must not exceed the header's supply capability. Standard USB 2.0 headers deliver up to 500 mA, so plan device loads accordingly. No active cooling or fan noise is involved.

Upgrade path and limits

This adapter replaces the need for a second USB header on the motherboard when only one is free. It is not for builders who need more than two ports or who require USB 3.0 or higher speeds. The jump is worth it when a single 9-pin header must serve two 2.0 devices such as a front-panel hub and a fan controller.

Questions about this item

How do I fit the 30 cm splitter onto a motherboard 9-pin USB 2.0 header without shorting pins?

Align the male connector with the header, press straight down, then press the 3M automotive adhesive tape on the cable back against the board or chassis to lock it in place; the short-circuit prevention outlet keeps pins from bridging if the cable is tugged.

What ongoing check does the 9-pin 1-to-2 USB 2.0 splitter require after installation?

Verify that the combined draw of both attached devices stays within the motherboard header’s 500 mA limit; if total current exceeds that, unplug the higher-drain device or use a powered hub instead.

At what point does the 30 cm internal USB 2.0 splitter hit its limit during sustained use?

The first limit is the 500 mA supply from the motherboard header; once the two ports together try to pull more than that, voltage drops and devices disconnect or fail to enumerate.
