Our full review
35 h on testThe NZXT Signal 4K30 is a compact external capture card built for streamers and content creators who want a straightforward way to bring high-quality external video sources into their broadcasts and recordings. Designed to integrate seamlessly with NZXT's own streaming ecosystem, particularly CAM and the broader Signal lineup, this capture card allows users to pull in footage from gaming consoles, DSLR cameras, or secondary PCs at resolutions up to 4K at 30 frames per second. Its straightforward USB connectivity ensures that setup remains simple, avoiding the complexity often associated with capture solutions, making it especially appealing to creators who want quality results without wrestling with technical configuration.
Built with simplicity and reliability in mind, the Signal 4K30 supports pass-through functionality, letting users monitor their capture source at higher frame rates while recording or streaming at 4K30, minimizing latency concerns during live production. The device is compact and durable, reflecting NZXT's minimalist design philosophy, and it's built to sit unobtrusively within a creator's desk setup alongside other streaming gear. Compatibility with popular streaming software such as OBS Studio and Streamlabs ensures that users can quickly incorporate the card into existing workflows, while NZXT's CAM software offers additional control and monitoring options for those already invested in the brand's ecosystem.

What owners say
5 verified reviews · 1,407 votes countedI picked this up to stream my PS5 gameplay and it's been rock solid. Setup was quick, passthrough latency is unnoticeable, and the HDR passthrough makes my stream look great. Only wish it did 4K60.
Been using this for a few months now alongside my NZXT PC components. Integration with CAM is nice since I already use it for monitoring. Video quality is crisp and I haven't had any dropped frames.
Works as advertised for 4K30 capture, but I ran into some driver conflicts when updating CAM software. Had to reinstall drivers twice. When it works, it works well though.
Compared to some pricier capture cards, this one punches above its weight. The build quality feels premium and it was genuinely plug-and-play on my Windows 11 rig. Recommend for beginners.
If you're fine with 4K30, this card is fantastic. I use it for Nintendo Switch and Xbox capture. Just don't expect 4K60 support, that's the main limitation here.
