NZXT expands its SFF lineup with new H2 Flow case, C850 SFX PSU and Mini PC

NZXT has introduced the H2 Flow Mini‑ITX case and the C850 SFX power supply, two compact components aimed at small form factor builders who want high‑end hardware support without moving to a larger chassis. On top of that, the company is also releasing a high-end limited‑run H2 Mini PC, although it will only be available in the US for now.

The H2 Flow is a 20.7L vertical Mini‑ITX chassis designed to maximise airflow while keeping the desk footprint small. Its layout supports up to 280mm AIO liquid coolers and graphics cards up to 331mm long, giving it headroom for modern CPUs and GPUs despite the compact size. Tool‑less fine‑mesh panels on all sides maintain cooling performance while helping with dust control, and NZXT includes a PCIe 5.0 riser cable for vertical GPU mounting alongside two pre‑installed F120Q fans.

The C850 SFX power supply is built for current and next‑generation GPUs, offering ATX 3.1 certification, 80 Plus Gold and Cybenetics Platinum efficiency ratings, and a 600W 12V‑2×6 connector. It uses a fully modular design with embossed cabling, a 92mm fan with a zero‑RPM mode for silent operation at low power loads, and Japanese capacitors rated for 105°C. NZXT backs the unit with a 10‑year warranty.

For buyers who prefer a ready‑made system, the H2 Mini PC brings the H2 Flow design to a prebuilt configuration assembled and tested by NZXT. It ships with either an AMD Ryzen 9800X3D or Intel Core Ultra 285K processor, a Gigabyte Mini‑ITX motherboard, an RTX 5080 graphics card, 32GB of DDR5 memory, 2TB of M.2 storage, a Kraken Elite 240mm AIO cooler, an 850W PSU, and Windows 11 Home. NZXT positions it as a way to access high‑performance SFF gaming without the complexity of building in a smaller enclosure.

All three products are launching this week. The H2 Flow Mini‑ITX case is priced at $149.99 / €149.99 / £129.99, while the C850 SFX PSU costs $199.99 / €159.99 / £139.99. The H2 Mini PC will be available exclusively in the US for $3499.
