NZXT H1 Mini-ITX Tower With 140MM Aio 650W SMPS PCIe 3.0 Extender Cabinet

The NZXT H1 is a premium mini-ITX gaming and workstation chassis engineered for high-performance builds in compact spaces, featuring integrated 140mm AIO liquid cooling support, 650W modular power supply, and PCIe 3.0 riser card for vertical GPU mounting. System integrators, enthusiast gamers, and content creators use this chassis to build powerful yet space-efficient computers without compromising on thermal management or component compatibility. This cabinet solves the critical challenge of fitting high-end components like RTX 40-series GPUs and high-TDP processors into small form factor builds while maintaining optimal airflow and thermal performance.

Product Overview

The NZXT H1 represents a paradigm shift in mini-ITX case design by combining a tempered glass dual-chamber architecture with integrated liquid cooling infrastructure. The chassis features a dedicated 140mm AIO mounting bracket in the upper chamber, allowing direct integration of all-in-one liquid coolers without additional radiator mounting solutions. The lower chamber houses the 650W modular power supply, creating thermal separation that reduces hot air recirculation and improves overall system cooling efficiency. The integrated PCIe 3.0 riser cable enables vertical GPU mounting, transforming the graphics card into a visual centerpiece while maintaining full bandwidth performance and eliminating the need for aftermarket riser cards.

This case utilizes a dual-chamber design principle that segregates power delivery and storage components from the main cooling loop, resulting in superior thermal stratification. The 140mm AIO support accommodates most mainstream liquid coolers from NZXT, Corsair, and other manufacturers, delivering CPU temperatures 15-20 degrees Celsius lower than traditional air cooling in mini-ITX configurations. The pre-installed PCIe 3.0 riser maintains full x16 bandwidth for graphics cards, supporting even the latest high-performance GPUs without bottlenecking. Tempered glass panels on multiple sides provide 270-degree visibility while the cable management system behind the motherboard tray keeps routing clean and organized.

How to Use

Begin by preparing your workspace and reviewing the detailed manual included with the chassis. Install the motherboard first by aligning the I/O shield with the rear cutout and securing with provided standoffs, ensuring no motherboard traces contact the case metal. Mount the 140mm AIO radiator in the upper chamber with the pump block oriented toward the CPU socket, using the pre-drilled mounting holes and included brackets. The radiator fans should exhaust hot air upward and outward for optimal thermal performance. Connect the AIO pump power to the CPU fan header and fan power to the integrated fan controller or motherboard headers.

Install the 650W power supply into the lower chamber with the fan facing downward toward the ventilation slots, securing with four screws. Route all modular cables through the dedicated cable channels behind the motherboard tray, keeping paths away from fans and heatsinks. Install your graphics card into the PCIe x16 slot and connect the included PCIe 3.0 riser cable to the GPU, then route the riser through the cable management guides to the vertical mounting bracket on the side panel. Secure the GPU with the vertical bracket and ensure all power connectors are firmly seated. Install storage drives in the 2.5-inch SSD bays or 3.5-inch HDD bay, then close both tempered glass panels and power on the system to verify all components initialize correctly.

Frequently Asked Questions

Does the NZXT H1 support air cooling or only AIO liquid cooling?

The H1 is primarily designed for AIO liquid cooling with the integrated 140mm mount in the upper chamber. However, you can use compact tower air coolers up to 120mm height in the lower chamber if necessary, though this compromises the thermal benefits of the dual-chamber design. We recommend using the integrated AIO support for optimal performance in this compact form factor.

What is the maximum GPU length supported with vertical mounting?

The NZXT H1 supports graphics cards up to 330mm in length when using the vertical GPU mounting bracket and PCIe 3.0 riser cable. This accommodates virtually all modern high-end GPUs including RTX 4090, RTX 4080, and RTX 4070 Super models. Verify your specific GPU dimensions before purchase to ensure compatibility.

Is the 650W power supply sufficient for high-end gaming builds?

The 650W 80 Plus Gold modular power supply is adequate for most mini-ITX gaming builds with single high-end GPUs and mainstream processors. For RTX 4090 with Ryzen 9 7950X or Intel Core i9-13900K, we recommend 750W or higher. The modular design allows flexible cable routing and the 80 Plus Gold certification ensures 90+ percent efficiency, reducing heat generation in the compact chassis.

Can I use the H1 without the vertical GPU mounting bracket?

Yes, you can install the GPU horizontally in the PCIe x16 slot without using the riser cable. However, this reduces the visual impact and may create thermal issues as the GPU exhaust air can recirculate into the main cooling chamber. The vertical mounting with riser cable is the recommended configuration for optimal thermals and aesthetics.

What motherboards are compatible with the NZXT H1?

The H1 supports all mini-ITX motherboards up to 270mm length, including models from ASUS, MSI, Gigabyte, and ASRock. Popular options include ASUS ROG STRIX Z790-I, MSI MPG B850I EDGE WIFI, and Gigabyte B850I AORUS ULTRA. Verify motherboard dimensions and I/O port placement before purchase to ensure clearance with the AIO radiator and case walls.
