NZXT H1 Features

H1 is a clean, and modern pc case with a small form factor. You can save your desk space because it needs a tiny area of 187mm x 187mm.

The top panel is minimal and neat, with a single power switch illuminated by an LED and a single USB-C, USB-A, and 4-pole audio I/O jack.

While allowing for system builds comparable to those found on large gaming PCs. When combined with a highly detailed set of side panels, the H1 provides access to fresh air for the 140mm AIO while also allowing for easy thermal load venting.

The NZXT H1 comes fully assembled, including the 650w power supply and PCI-e graphics card riser. Cabling is neatly bundled and pre-routed throughout the chassis, so cable management is a non-issue even prior to assembly.

NZXT H1 case

The NZXT H1 case various types of PC cases among the H210, H510, and H710 series. It’s based on SFF(small form factor) concept. The case is pretty and clean. 13-liter Mini-ITX case Price at $199. NZXT thinks to the simplified the building process, It means they installed pre-routed cables and integrated PSU, AIO, and PCIe Gen 3 riser cable. I have no problem with the NZXT H1 case, It is a great one for Mini ITX lovers.

NZXT H1 Accessories


H1 includes a 650W power supply to power up all components. the power supply tucked into the H1’s top. 

Mini-ITX motherboard

Z590I ITX Motherboard is used for the build. Also, The all-AMD build I installed in this magnificent chassis utilizes one of the best mini-ITX Ryzen motherboards on the market, the ASRock X570 Phantom Gaming-ITX/TB3, which simplified the process considerably.

PC chassis

The intelligent chassis design does not end with the installed extras; it all begins with the case’s toolless access, both from the exterior and when dropping components into H1. Though intelligent chassis design does not always equate to intelligent packaging.

NZXT H1 AIO Replacement

The NZXT H1 includes a standard 140 mm AIO water-cooling solution, which can be replaced with an aftermarket kit as long as the tubing fits in the tight space. However, unless you are certain that everything will fit, this is not recommended.

That can handle even the High-end desktop processors, such as the Intel Core i9 and AMD Ryzen 9 series. If you want to replace it with an aftermarket solution, another AIO is preferable, though a low-profile air blower will suffice.

It’s critical to consider the tubing when looking for a replacement AIO. The H1 is a very small chassis with very little space between the CPU and the case panel. The H1’s AIO is designed to address this issue by utilizing 90-degree rotating fittings on both the radiator and the cooling block. Most AIOs do not have radiators with 90-degree rotators.

It’s especially bad for low-profile coolers. You’ll need a decent blower, but if you use a case fan instead of the AIO radiator, you’ll only have about 65 mm of clearance. What is our recommendation? Use the included AIO, or if it stops working and is no longer under warranty, purchase a replacement from NZXT.

How to install RTX 3080 in NZXT H1 mini Pro PC

The temps are a lot better now with these changes in the structure of PC casing

  1. Vented front panel and exhaust fans in the back.
  2. 15mm Rear Panel Extension with 2 x 120mm Slim Fans, 
  3. And Lowered MB/GPU tray to add 25mm clearance for longer GPU (Gigabyte RTX 3080 Ti) 
  4. The card was a really tight fit, I had to unscrew the top of the case to put it into the H1 as well as remove the filter on the side panel, but once I got through that everything fit perfectly fine.

Installing drivers was a bit wacky, the first installation messed up but after uninstalling the drivers and doing a custom installation, it works completely fine.

airflow seems okay, not the best. Idle temps, I’m seeing 30-40°. Unigine 2 Superposition benchmark on 8k I got a score of 5399, with avg. 40 fps and min temps of 53°c and max temps of 77°c. 4k optimized I got a score of 12810, with avg. 96 fps, min temps of 31°c, and max temps of 75°c.

The RTX 3080 Ti usually hovers around 75C at full load. The CPU is a Ryzen 5800X which is known to run very hot. I’m still using the original 140mm AIO but with a Noctua 140mm fan. Cinebench all core load hits 80 – 82C and usually hovers around 60-65C when in-game.

If anyone was curious, I’m presently utilizing the stock power supply, and so far I’m not seeing any issues with it. Have to note my computer currently resides in my living room at room temperature (around 20-22°c).

At 1080p, I wouldn’t see a huge difference in fps compared to other GPUs due to the CPU having a good amount of load causing the GPU to work less. once I went to 1440p on my ultrawide, that’s where it truly shines.

Overall the card seems like a really good choice for anyone who’s looking for a 3080 for their H1. The stock PSU looks like it is capable of handling the 3080 + 3800x, but maybe to be safe you might want to upgrade to a 750 watt.


Is the NZXT H1’s 140mm AIO controlled by NZXT’s CAM software?

Unlike the other AIOs on this list, this one is not powered by CAM. The BIOS on your motherboard is in charge of controlling the cooling.

Would the 650W PSU included with the NZXT H1 be controllable by NZXT’s CAM software?

Due to the fact that the H1 650W PSU is not a CAM-powered product, it would not be visible or controllable within our software’s CAM environment.

Is the 650W power supply sufficient for NVIDIA’s new 30 series GPU lineup?

Nvidia’s recommended power supply wattages:

  • RTX 3090 : 750W
  • RTX 3080 / 3080 Ti : 750W
  • RTX 3070 / 3070 Ti: 650W

Note: Nvidia’s recommended power supply wattages are based on a PC configured with an Intel Core i9-10900K processor. 

Would it be possible to add more SATA connections to this PSU?

While this is possible, depending on your build and the design of this case, there may be insufficient space for further cable routing or installation of additional 2.5-inch storage devices.

What size GPUs can I fit into the H1?

Depending on some of the dimensions of your GPU, there can be problems with clearance within the H1 case. These dimensions are the following:

  • Dimensions – 305mm (L) x 128mm (W) OR 265mm (L) x 145mm (W)
  • Thickness/Depth – Up to 2.5 slots (50mm)

Could an air cooler be used instead of an AIO? 

Yes, this is feasible; however, it has not been tested by NZXT, and so compatibility may vary. We believe that most Small Form Factor CPU air coolers will fit in the AIO mounting bracket with just a fan. This is not fully certain, as this case is designed to handle the H1’s 140mm AIO.

Is it possible to upgrade the NZXT H1 with RGB lighting?

There is space beneath the front panel for several LED strips. These would need to be powered by your motherboard, as there is insufficient room in the H1 for our NZXT RGB & Fan Controller to fit comfortably.
