What the capture card does

The physowell HDMI to USB 3.0 capture card accepts a 4K 60 Hz HDMI input and records or streams at 1080p 60 fps. It works with Windows, Linux and macOS without driver installation and supports consoles such as PS4, Switch and Xbox as well as PCs and media players.

Thermals noise and power

The device draws power from the USB 3.0 port and operates between 0 and 70 degrees Celsius. Video processing is handled on the dongle so the host CPU is not burdened and the aluminium shell dissipates heat without a fan.

The deciding specification

It captures a single 1080p 60 fps channel over USB 3.0 at 300 to 350 MB/s throughput. Buyers who need 4K capture or multiple simultaneous inputs should choose a different device.

Questions about this item

How do I connect the HDMI loop output for 4Kp60 passthrough?

Connect the source to the HDMI input, then run a second HDMI cable from the loop output to your display; the card passes 4Kp60 through while capturing 1080p60 over USB 3.0.

Does the aluminium shell need active cooling during long streams?

The card draws power from the USB 3.0 port and operates up to 70 °C; no fan is fitted, so ensure the chassis has airflow and avoid enclosing the dongle.

At what point does sustained capture hit the USB 3.0 throughput ceiling?

Continuous 1080p60 capture runs at 300–350 MB/s; the USB 3.0 link is the first bottleneck before CPU or storage limits appear.
