Why consider this model?

  • An earlier external card for a Windows/OBS workflow that needs more recording headroom than the HD60, especially 1080p120 or 4K30 capture, while the product's separate display path supports selected HDR and high-refresh inputs. Its manual clearly separates 4K30 recording from 4K60 HDR passthrough.

Tradeoffs to weigh

  • Do not read the 4K60 HDR pass-through line as 4K60 or HDR recording. NZXT's manual lists 4K30 as the maximum stream/record resolution and says HDR10 pass-through is hardware-converted to SDR color. Its separate tables do not give a complete simultaneous mode matrix, so this assessment does not combine 1080p120 capture with a high-refresh passthrough choice. The exact product code ST-SESC1-WW should be checked on the seller's package; new-unit availability is not established here.
