With the NZXT H2 Flow, NZXT presents a new interpretation of Small Form Factor PCs. The vertical Mini-ITX case, the powerful C850 SFX power supply unit and the pre-built H2 Mini PC aim to accommodate high-end hardware in a minimum of space – without compromising on cooling, efficiency or design. The new components are aimed at anyone who wants to achieve maximum performance in a compact setup.
- 20.7-litre mini-ITX case with optimized airflow
- ATX 3.1 power supply with 80 PLUS Gold & Cybenetics Platinum
- Support for GPUs up to 331 mm and 280 mm AIO coolers
- H2 Mini PC as a pre-configured high-end option (USA exclusive)
NZXT H2 Flow Mini-ITX: Compact design meets high-end compatibility
The NZXT H2 Flow Mini-ITX case is based on a vertical 20.7-liter layout and requires less floor space than an A4 sheet of paper. The case is therefore clearly aimed at compact gaming setups, minimalist workstations or living room builds. Despite the small footprint, the hardware compatibility remains at a remarkably high level.
Graphics cards with a length of up to 331 mm can easily be accommodated, which means that even the latest high-end GPUs can be integrated. At the same time, the case supports AIO liquid coolers up to 280 mm, which reliably cools even powerful CPUs under gaming or streaming load. Two pre-installed F120Q fans provide a solid exhaust air solution ex works.
Special attention is paid to the airflow concept. Tool-free removable fine dust filter panels on all sides maximize the airflow and reduce dust deposits inside. This not only improves the cooling performance, but also the longevity of the components. The design is complemented by integrated cable management with Velcro straps and a pre-installed PCIe 5.0 riser cable for vertical GPU mounting. The result is a tidy interior layout with optimized air circulation – a decisive factor for small form factor builds.
C850 SFX power supply: ATX 3.1 and efficiency for modern high-end GPUs
Alongside the case, NZXT is also presenting the C850 SFX power supply, which has been specially designed for high-performance SFF systems. With ATX 3.1 certification, it is fully compatible with current power supply standards and next-gen graphics cards. The integrated 12V 2×6 connection with 600 watts enables the direct operation of modern GPUs without adapter solutions.
In terms of efficiency, the power supply combines 80 PLUS Gold with Cybenetics Platinum certification. This means high energy conversion efficiency, reduced waste heat and overall quieter operation. A 92 mm fan with Fluid Dynamic Bearing and Zero RPM mode remains completely silent at low loads and only becomes active when required.
For long-term stability, NZXT relies on fully modular cables, embossed cables with cable combs and 100 percent Japanese capacitors, designed for 105 °C. The package is complemented by comprehensive protection mechanisms against overcurrent, overvoltage and overheating. A ten-year guarantee underlines the demand for reliability and future-proofing – particularly relevant for compact systems with high power density.
H2 Mini PC: Small form factor as a pre-configured high-end system
In addition to the case and power supply unit, NZXT is launching a preconfigured solution on the market with the H2 Mini PC. The system uses the same compact form factor and performance-oriented design of the H2 Flow, but is delivered fully assembled and ready to use. Variants with Intel or AMD platform are available.
With a price of 3,499 US dollars, the H2 Mini PC is clearly positioned in the high-end segment and as a competitor to the ASUS ROG NUC (our test). Availability is initially restricted to the US market and limited in time. NZXT is therefore targeting users who want a powerful small form factor system without having to build it themselves.
Conclusion: NZXT H2 Flow strengthens the small form factor trend
With the NZXT H2 Flow Mini-ITX case, the C850 SFX power supply and the H2 Mini PC, NZXT is significantly expanding its portfolio in the small form factor sector. The combination of compact design, high hardware compatibility and modern power supply shows that powerful gaming and creator systems do not necessarily require large towers.
The market launch will take place on February 17, 2026, with the H2 Flow costing 149.99 euros (EMEA) and the C850 SFX 159.99 euros (EMEA). The H2 Mini PC starts at 3,499 US dollars in the USA.
