What is a Capture Card and Do You Need One?
A capture card is a hardware device that takes video input from a source (console, camera, or second PC) and passes it to your streaming/recording computer. It converts the video signal into a format your PC can capture and process through software like OBS.
Best External Capture Cards
External capture cards connect via USB and work on any computer: no installation, highly portable. These are the most popular choice for most streamers.
- Plug-and-play, no drivers
- Excellent software (4K Capture Utility)
- 4K60 HDR pass-through
- Works on Mac and PC
- Captures at 1080p60 (not 4K capture)
- Pricier than basic alternatives
- Cam Link: camera-to-webcam focused
- Tiny, portable form factor
- No software required
- Cam Link: no pass-through
- No standalone recording
- Standalone recording to SD card
- 4K30 capture
- USB-C connection
- RECentral software is clunky
- No HDR capture
Best Internal (PCIe) Capture Cards
Internal capture cards install inside your PC in a PCIe slot. They offer higher performance, lower latency, and support for higher resolutions: ideal for dual-PC setups or demanding professional use cases.
- True 4K60 HDR capture
- VRR support (unique)
- Ultra-low latency
- Requires desktop PC with PCIe slot
- Not portable
- More expensive
- Hardware H.265 encoding
- 4K60 HDR capture
- Slightly cheaper than Elgato 4K X
- No VRR support
- RECentral software not for everyone
Buyer's Guide: Which Capture Card Do You Need?
For console gaming + streaming (PS5/Xbox)
→ Elgato HD60 X (~$160). Handles everything modern consoles output, pass-through is excellent, and it's genuinely plug-and-play.
For using a camera as a webcam
→ Elgato Cam Link 4K (~$130). Specifically designed for this. Your mirrorless camera will look dramatically better than any webcam.
For dual-PC streaming setups
→ Elgato 4K X or AVerMedia Live Gamer 4K. Internal cards are essential for dual-PC due to lower latency and higher bandwidth.
For budget console streaming
→ Look for the Elgato HD60 S+ on sale or the AVerMedia LGP2 (~$80–100). At this price point, 1080p60 capture is perfectly adequate for most streams.
Frequently Asked Questions
Do I need a capture card if I stream PC games?
No. If you're streaming games that run on the same PC as OBS, you don't need a capture card at all. OBS captures your screen and game audio directly. Capture cards are only needed when the video source is a separate device: a console, a camera, or a second gaming PC.
What capture card works with PS5 and Xbox Series X?
The Elgato HD60 X is the most popular choice and handles both PS5 and Xbox Series X output reliably. It supports 4K30 capture with 4K60 HDR pass-through, meaning your TV still gets the full-quality signal while you record or stream a lower resolution. The Elgato 4K X (internal PCIe) is the upgrade for those who want true 4K60 capture.
What is the difference between internal and external capture cards?
External capture cards connect via USB and work on any laptop or desktop with no installation. Internal cards install inside a desktop PC in a PCIe slot and offer lower latency and higher bandwidth. External cards suit most streamers. Internal cards are preferred for dual-PC setups and professional 4K recording.
Can I use a mirrorless camera as a webcam without a capture card?
Some cameras support USB webcam output natively (Sony, Canon, Fujifilm all have this). If your camera supports it, you may not need a capture card. However, a dedicated capture card like the Elgato Cam Link 4K typically provides more reliable performance and lower latency than USB webcam modes.
Is the Elgato HD60 X worth the price over cheaper alternatives?
For most streamers, yes. It's genuinely plug-and-play, the software is excellent, and 4K60 HDR pass-through is a meaningful feature. Budget alternatives exist but often require more driver troubleshooting. If budget is tight, look for the HD60 S+ on sale rather than buying a no-name alternative.
