Usb 3.2 Gen 2 Motherboard Connector
If you lot are new to PC building then trying to understand the unlike headers can get a bit daunting. Basically, a motherboard typically has several different headers (connectors) for connecting various devices. One such header type are the USB headers. Then what are USB Headers?
USB headers are basically the concrete connectors found on the motherboard for connecting the extra USB ports institute on the PC case.
In that location are different types of USB headers intended for dissimilar versions of USB ports on the PC case. And so for instance, a USB two.0 header is different from a USB 3.0 header.
In the following article I will talk in particular about USB headers, their unlike types, simply first let u.s.a. talk about the unlike USB versions considering they are atrociously confusing to the uninitiated.
Different USB Versions and Their Speed
There are many different versions of the USB standard equally you may already know. But at the same fourth dimension know that who ever has been deciding the classification of the different versions (Looking at you -> USB-IF) has literally wreaked a havoc for consumers particularly with how the version iii.0 has been bifurcated.
At the same time you MUST understand the unlike versions as this will give you an insight into not just their speeds, but likewise assist you empathise the different types of headers.
There are essentially 8 USB versions/names that yous may meet. They are summarized in the table beneath.
You can run into how confusing the names for the USB tin can exist.
Primal points to note here are as follows:
- USB 3.0, 3.one Gen 1 and USB 3.two Gen one are all the Aforementioned, just different names revised over and over with different versions. They all use the specifications called SuperSpeed.
- Frequently when we talk almost USB three.1 speeds, nosotros are really referring to USB 3.ane Gen 2 speeds (10 Gbps) Not Gen 1 since USB 3.i Gen 1 is the same as USB three.0 (5.0 Gbps).
- USB 3.two Gen ii has the same specifications as the USB 3.i Gen 2 which is called SuperSpeed+.
- The merely new specifications USB 3.2 introduces are dual channels usable only over Type C ports. They double the transfer rate of the older specifications. It is thus named as USB 3.2 Gen 2×2 (indicating dual channel). This specification is called SuperSpeed++and can reach twenty Mbps.
- USB 3.2 Gen 1×two uses the specifications of Gen 3.0 (aka SuperSpeed) and doubles it over two channels (i.e 5.0 10 2 = ten Gbps).
- USB 3.2 Gen 2×ii uses the specifications of USB 3.ii Gen 2 (SuperpSpeed+) and doubles it (i.e 10 x 2 = 20 Gbps) and thus conveniently calling itself SuperSpeed++.
If you are confused on the start glance, its ok. Even the most expert PC builders often do.
The only important USB versions you need to take note of are as follows as they brought a change in speed.
- USB 2.0 = ~0.5 Gbps
- USB 3.0 = 5.0 Gbps (aka USB three.1 Gen 1, USB 3.2 Gen 2) – SuperSpeed
- USB 3.one Gen ii = ten.0 Gbps (aka USB iii.2 Gen two) – SuperSpeed+
- USB 3.two Gen 2×2 = twenty.0 Gbps – SuperSpeed++
Hopefully, with the USB four.0 around the corner, the naming convention volition get a bit simpler.
With that out of the way, at present let us now expect at what are USB headers.
What are USB Headers?
USB headers are basically connectors on the motherboards for connecting the USB ports found on the PC Case.
If your PC instance has USB ports, then it will also come with plugs that need to be connected to the correct headers.
Different USB versions have dissimilar USB headers on the motherboard. In other words, a USB 2.0 header is unlike from a USB three.0 header.
The following section explain this.
Blazon of USB Headers
There are essentially four types of USB headers:
- USB 2.0 Header
- USB iii.0 Header
- USB iii.1 Gen 2 Header
- USB 3.2 Gen 2×2 Header
Therefore, depending upon what USB ports you have on your PC example, y'all will connect them to the corresponding header.
So USB two.0 ports will go into the USB 2.0 header, USB 3.0 ports will become into USB 3.0 headers and and so on.
one. USB 2.0 Header
These are the simplest to follow.
They are small and their pins are arranged in a 5×2 grid. USB two.0 headers have 9 pins. The 10th missing pivot from the array serves every bit the primal for adjustment the plug correctly.
If yous accept a PC case with USB 2.0 ports, it volition be accompanied with this plug:
2. USB 3.0 Header – aka USB 3.one Gen 1, USB 3.two Gen 1 Header
A USB 3.0 header has 19 pins arranged in a 2 10 x array.
This header has been chosen by many different names including
- USB 3.0
- USB three.i
- USB 3.1 Gen one
- USB 3.2 Gen ane
Basically the name that you find for this header on a motherboard specsheet depends upon WHEN the motherboard was manufactured.
The latest motherboards label this header as USB 3.ii Gen one header. The older motherboards may take the other names.
So basically as the USB standard changes the classification, so do the motherboard manufacturers.
But essentially, they are Nevertheless.
If you accept a PC example with USB iii.0 / 3.i Gen 1 / 3.2 Gen 2 ports, then it will come with a cable like to the one shown below:
3. USB three.one Gen 2 Header – aka USB iii.2 Gen ii Header
A USB 3.1 Gen 2 header has a very unique form gene. It does not have pins sticking out like the residue of the USB headers.
In the contempo motherboards, this is known as the USB 3.2 Gen 2 header.
If y'all have a PC case with a relevant port, so information technology volition come with the following cable.
four. USB three.two Gen 2×ii Header
These are similar to the USB 3.one Gen 2 headers to a higher place. However, they have dual channels are specifically labelled as USB 3.2 Gen two×2 on the specifications.
These are quite rare and only a select few top of the line motherboards feature this at the moment.
How To Locate USB Headers?
USB headers are often located at the lesser or the right edge of your motherboard.
But substantially, in that location are two means to locate the USB headers exactly.
- Concrete Inspection
- Through the Transmission
1. Physical Inspection
If you can notice your way beyond the motherboard, and then USB headers aren't besides hard to spot.
They are often labelled and may as well indicate what version they vest to.
Here yous can run across that my motherboard has ii USB ii.0 headers. They are labelled as F_USB2 and F_USB1. I can tell by the pin count and the size of the header that it belongs to USB 2.0.
two. Through the Manual
Another piece of cake way to effigy out where your USB headers are located is to refer to your motherboard's layout in the manual.

FAQ
Can You Use a USB three.0 Case Port with a iii.2 Motherboard Header?
If the motherboard header is a 19 pin connector then yeah, you tin.
USB 3.0, USB three.1 Gen ane and USB 3.ii Gen one ports are even so. They use the same header and connector and have the aforementioned transfer speed of 5.0 Gbps.
However, if you accept a USB three.1 Gen 2 port (aka USB 3.2 Gen two port), then yous will demand to purchase an adapter to connect your 3.0 case ports.
USB Ports on the Back I/O Panel DO NOT Connect to USB Headers
Motherboards also have a USB ports on the dorsum I/O panel. These do non connect to the USB headers.
USB Ports on the Case are Not the Same every bit USB Expansion Cards
A USB expansion card fits into the PCIe slot. As such they interface with your PC via the PCIe lanes directly and hence Practice NOT require to exist connected to USB headers.
How Many USB Ports a USB Header Can Support?
Generally, USB headers can support ii USB ports per header, but that too depends upon the type of header information technology is.
- USB 2.0 Header – Supports 2 USB ports
- USB 3.0 Header now chosen USB 3.2 Gen 1 Header – Supports 2 USB ports
- USB 3.1 Gen 2 Header now called USB 3.2 Gen 2 Header –supports i port (Unremarkably Type C)
- USB 3.2 Gen 2×2 Header – support one port (Type C only)
Is USB 3.2 Gen 2 the Aforementioned every bit Thunderbolt 3?
No, they are non. Thunderbolt 3 ports have a completely different header.
Additionally, Thunderbolt three is much faster at 40 Gbps transfer speed! To put that into perspective, USB three.2 Gen 2 reaches 10 Gbps and dual channel USB iii.2 Gen 2×two reaches 20 Gbps transfer speed.
Hence Thunderbolt 3.0 is twice equally fast as the dual channel USB 3.ii Gen 2×two.
