Streaming on PC has become increasingly popular over the years, with many gamers and content creators turning to platforms like Twitch and YouTube to share their gaming experiences with the world. However, one question that often arises when it comes to streaming on PC is whether or not a capture card is necessary. In this article, we’ll delve into the world of capture cards and explore their role in PC streaming.
What is a Capture Card?
A capture card is a device that allows you to capture and record video and audio signals from external sources, such as gaming consoles, cameras, and other devices. In the context of PC streaming, a capture card is used to capture the video and audio signals from your PC and transmit them to your streaming platform of choice.
How Does a Capture Card Work?
A capture card works by connecting to your PC via a USB or PCIe interface and capturing the video and audio signals from your PC’s graphics card. The captured signals are then processed and encoded by the capture card, which converts them into a digital format that can be streamed online.
Types of Capture Cards
There are several types of capture cards available on the market, each with its own unique features and capabilities. Some of the most common types of capture cards include:
- Internal Capture Cards: These capture cards are installed directly into your PC’s motherboard and connect to your graphics card via a PCIe interface.
- External Capture Cards: These capture cards connect to your PC via a USB interface and are typically smaller and more portable than internal capture cards.

What is a capture card and what does it do?
A capture card is a hardware device that allows you to capture and record video and audio signals from external sources, such as a gaming console, camera, or other devices, and transfer them to your computer. It acts as a bridge between the external device and your computer, enabling you to stream or record content from the external device on your computer.
The capture card is usually connected to the external device via an HDMI or other video cable, and then connected to the computer via a USB or PCIe connection. The card then captures the video and audio signals from the external device and sends them to the computer, where they can be streamed or recorded using software such as OBS Studio or XSplit.
Do I need a capture card to stream on PC?
Not always. If you’re streaming games or other content directly from your PC, you don’t need a capture card. Your computer’s graphics card can handle the video processing and encoding, and you can use software such as OBS Studio or XSplit to stream the content directly from your PC.
However, if you want to stream content from an external device, such as a gaming console or camera, you will need a capture card. The capture card is necessary to capture the video and audio signals from the external device and transfer them to your computer, where they can be streamed or recorded.
What are the benefits of using a capture card?
Using a capture card can provide several benefits, including high-quality video and audio capture, low latency, and the ability to stream or record content from external devices. Capture cards can also provide additional features such as hardware encoding, which can reduce the load on your computer’s CPU and improve streaming performance.
Another benefit of using a capture card is that it can provide a more stable and reliable connection between the external device and your computer. This can be especially important for live streaming, where a stable connection is critical to prevent dropped frames or other issues.
What types of capture cards are available?
There are several types of capture cards available, including internal PCIe cards, external USB cards, and Thunderbolt cards. Internal PCIe cards are installed directly into your computer’s motherboard and provide a high-speed connection between the capture card and your computer’s CPU.
External USB cards, on the other hand, are connected to your computer via a USB port and provide a more portable and flexible solution. Thunderbolt cards are high-speed cards that use the Thunderbolt interface to provide fast data transfer rates.
How do I choose the right capture card for my needs?
To choose the right capture card for your needs, you’ll need to consider several factors, including the type of content you want to stream or record, the resolution and frame rate you need, and the connectivity options you require.
