For years, I’ve been fascinated by the idea of a console killer PC, something small enough to sit under the TV yet powerful enough to rival a modern console like the PlayStation 5. Mini-ITX builds have always promised that dream, but there’s usually a compromise. You can either opt for blistering performance with loud thermals or a compact box that struggles to push modern games at 4K.
That changed when I decided to take an unconventional path by cramming Nvidia’s RTX 4080 Super Founders Edition into a Deepcool CH160 mini-ITX case. On paper, it sounded like a thermal nightmare, not to mention the cable mess. But in reality, it turned into my favorite gaming system yet, one that completely satisfies my need of owning a console .
Building a powerhouse from leftover parts
The build wasn’t about chasing the latest components as most of the hardware came from an older system I had lying around. The core setup includes an Intel Core i7-11700K, a Gigabyte Z590i Vision D mini-ITX motherboard, and 32GB of DDR4-3200MHz memory. Storage duties are split between a 250GB Samsung 970 Evo Plus PCIe Gen 3 SSD for Windows and a 2TB Kingston NV1-E drive for my growing game library.
Power comes from a Cooler Master V750 SFX PSU, while cooling duties are handled by a Deepcool AN600 low-profile CPU cooler, which I modified with an Arctic P12 Max fan for improved thermal performance. I also added a pair of Arctic P12 ARGB fans to keep airflow steady within the CH160.
What ties it all together is the RTX 4080 Super Founders Edition, a behemoth of a GPU measuring over 300mm in length. The fact that it fits at all inside this compact case feels like an engineering miracle, even though the case is very affordable.
Making it all fit
Getting everything to fit wasn’t straightforward. Once I installed the motherboard and power supply, I had to plan my next steps carefully. The Deepcool CH160 officially supports full-length GPUs up to 305mm, which seems quite intentional since the RTX 4080 Super Founders Edition (and the RTX 4090) measures 304mm.
With just 1mm of clearance at the front, getting the GPU inside the case was not easy. Thankfully, the case includes removable fan brackets, which allowed me to slightly flex the rear panel and somehow maneuver the bulky GPU inside by sliding it in at an angle.
The next challenge was routing power to the GPU. The bundled 16-pin power-connector adapter requires three dedicated 8-pin PCIe power cables from the PSU. Since the braided cables on the adapter were quite stiff, I couldn’t tame them properly and was left with a mess dangling outside the side panel.
Bending and cramming the adapter and cables was not an option, and I had no plans to become a victim of the infamous 12VHPWR connector-melting fiasco. Hence, I resorted to a custom 16-pin 12V-2×6 power cable from Moddiy, as they offer high-quality PSU cables with free shipping worldwide.
With just enough space under the GPU to route the power cable, I managed to achieve a clean and properly managed GPU setup. Next, I had to deal with the front-panel cables, which were quite long but flat, allowing me to route them around the front of the GPU.
Airflow was the next concern. The 4080 Super Founders Edition comes with a giant heatsink that’s practically overkill, but heat can still build up quickly in a small chassis. I went with a rear 120mm intake fan to bring in extra air for the top-down CPU cooler and a front exhaust to expel hot air. After some fan-curve tuning, I found a balance that kept GPU temperatures in the mid-60s under load without excessive noise. The system now idles with the CPU around 40°C and the GPU at 35°C, and stays fairly quiet during gaming sessions.
Console-sized, but console-crushing performance
Once everything was running, I quickly realized this setup wasn’t just a novelty, it was a serious gaming machine. In Cyberpunk 2077 and Alan Wake 2, both notorious GPU hogs, the system comfortably pushes 90–100 FPS at 4K Ultra with DLSS enabled. The RTX 4080 Super FE doesn’t even break a sweat.
With a wireless Xbox controller connected and Steam Big Picture Mode active, this mini-ITX PC transforms into a 4K gaming console that loads faster, looks sharper, and plays smoother than anything Sony or Microsoft currently offers.
Beyond performance, the flexibility of this setup is what truly makes it shine. I can switch from gaming to editing, streaming, or even running emulators without compromise. Storage upgrades are easy, mods are limitless, and I’m not locked into any single ecosystem.
Yes, it took me a few days of labor, but once configured, it has been rock-solid. The compact form factor means it sits neatly under my TV, and the integrated handle on top of the case allows me to carry it around.
Small form factor done right
The Deepcool CH160 deserves credit here. It may not be as premium as the Fractal Design Terra, but it is one of the few compact cases that manage to balance airflow, GPU clearance, and aesthetics in a design that is slightly bigger than most console enclosures. Combine that with Nvidia’s efficient Ada Lovelace architecture, and you’ve got a recipe for near-silent 4K gaming in a system that fits in a duffle bag.
Of course, this kind of build isn’t for everyone. Cable management can really test your patience, thermals require extra attention, and repurposing old parts means accepting potential bottlenecks. My Core i7-11700K, for instance, didn’t limit performance, but going with anything older might. Still, the end result is worth it — a fully functional, ultra-powerful gaming console built from parts I already owned.
Turning the page on consoles
What started as an experiment has quietly turned into my go-to gaming machine. This tiny PC outperforms the PS5 in nearly every way including higher frame rates, better image quality, and complete control over settings.
Building something this compact and capable reminds me why I fell in love with PC gaming in the first place. With a bit of creativity, even old hardware can feel brand new, especially when it’s wrapped around a GPU as capable as the RTX 4080 Super FE.
So yes, I squeezed a flagship GPU into a mini-ITX case. But what I really did was build the console I always wanted, one that doesn’t compromise on performance, power, or personality.
