How to Use a Capture Card? | Source to Stream in Six Steps

A capture card is the bridge between a device that produces video and a computer that records it. The console, camera, or PC feeds HDMI into the card, the card sends that signal over USB to software like OBS, and a second HDMI connection passes the picture through to your monitor with no lag. Learning how to use a capture card comes down to three cables and one software pick, and most mistakes happen when people skip a step or misread the specs.

When Do You Actually Need a Capture Card?

You need one when your computer can’t natively ingest the signal you want to record. That covers streaming PlayStation or Xbox gameplay, capturing a DSLR or mirrorless camera feed for a stream, and grabbing output from a second PC that you want to keep free of recording overhead.

The card shows up in your capture software as a video capture device, so the computer never has to handle the source directly. If your goal is just recording your own screen on one machine, a capture card won’t help — that’s what built-in screen recording is for.

Setting Up a Capture Card: The Connection Order That Works

The order matters because each connection depends on the one before it. Whether you’re wiring an Elgato HD60 X or a Razer Ripsaw X, the sequence is the same six steps.

1. Plug the card into your PC with a USB 3.0 cable. Both the Elgato HD60 X and the Razer Ripsaw X require USB 3.0, so use a USB 3.0-capable port and cable — a USB 2.0 port will fail or drop frames.
2. Connect the HDMI source to the card’s HDMI 2.0 input. For the HD60 X this is the console, PC, or camera; for the Ripsaw X, Razer positions it as a camera capture card, and the input is labeled clearly on the unit.
3. Run the passthrough HDMI cable from the card’s output to your monitor or TV. This is what lets you play with zero added latency while the card captures in the background.
4. Install capture software. Elgato supports its 4K Capture Utility on Windows and OBS Studio on both Windows and macOS for the HD60 X. Razer lists OBS and Streamlabs for the Ripsaw X, and notes that Synapse is not required — the card is plug-and-play.
5. Add the card as a video capture device. In OBS, add a new Video Capture Device source and select the card’s name from the dropdown. It should appear once the USB connection is live.
6. Confirm video and audio, then hit record or go live. If the picture is black, check the source for HDCP —

What the Current Models Actually Do

Most capture-card confusion comes from mixing up passthrough resolution with capture resolution. The Elgato HD60 X, for example, passes through up to 2160p60, 1440p120, or 1080p240 with VRR and HDR, but its capture tops out at 2160p30, 1440p60, or 1080p60 HDR — you can play in 4K while recording in 1080p. HDR capture itself is currently Windows-only, so macOS and iPad users get standard dynamic range. The table below keeps the two mainstream options straight.

Camera users should note that Razer recommends a camera with clean HDMI output — meaning the feed has no menus, focus boxes, or battery indicators baked in — at the resolution and framerate the card supports. Cleaning the Razer Ripsaw X also has a rule of its own: unplug every cable and wipe it with a lint-free microfiber cloth only.

If you’re shopping, the HD60 X is discontinued, so new prices are inflated and stock is disappearing. The Ripsaw X is the current camera-focused option, and for budget console capture, our tested best cheap capture card roundup sorts the affordable models that don’t fall apart under load.
