In the competitive world of gaming hardware, size often dictates capability. The PlayStation 5, with its substantial dimensions of 390 × 260 × 104 mm and a hefty 4 kg weight, has been a point of contention for console enthusiasts who value portability. Lead architect Mark Cerny defended these proportions as “necessary” to accommodate the console’s powerful components and robust cooling system. However, a Japanese modder known as Tera has demonstrated that this bulkiness is not inevitable.
The Transformation
Tera, a skilled electronics engineer and YouTube personality, has reimagined Sony’s flagship console by creating a portable “briefcase” PS5 that not only addresses the size issue but also adds functionality. This modified console, featuring a built-in 15.6-inch display, is remarkably 60 percent smaller than the original—measuring just 357 × 224 × 53 mm and weighing in at 2.8 kg. This remarkable feat represents a 60 percent reduction in volume and mass while maintaining full functionality.
Inside the Miniature Console
What makes this modification especially impressive is that Tera didn’t just shrink the PS5; he enhanced it with additional components. His compact build includes:
- An integrated 15.6-inch LCD screen
- Two internal stereo speakers
- A headphone/aux jack
- An extra USB-A port
- A heat monitor with display
- A distinctive arcade-cabinet-style power button
The only compromise was the omission of the PS5’s USB-C port, but this seems like a small trade-off given the other improvements.
Cooling Innovation
The biggest engineering challenge in shrinking the PS5 was addressing its cooling requirements. The original console draws approximately 210 watts of power—roughly triple that of the PS4. This high power consumption necessitated Sony’s oversized cooling system, which in turn contributed significantly to the console’s large footprint.
Tera’s solution was an innovative cooling redesign that replaced the original stock cooler with a server-grade vapor-chamber heatsink rated for 145W TDP. While technically below the PS5’s 180W requirement, Tera’s expertise allowed him to make it work effectively. This vapor chamber technology is commonly used in high-performance computing environments where dense heat dissipation is critical (Source: ennergroup.com).
The cooling solution was further enhanced with custom 3D-printed fan blades inspired by Sony’s original cooler. Tera also designed a custom shroud to efficiently channel air through the new heatsink system. Perhaps most impressively, he built a bespoke heat sensor and controller, complete with a small chassis-mounted display for manual monitoring. To maximize thermal efficiency, Tera even applied the same liquid metal thermal compound between the heatsink and APU that Sony uses in their retail PS5 units (Source: radianheatsinks.com).
Performance and Design
The finished product is aesthetically pleasing and functionally sound. The briefcase design slips comfortably into a 15.6-inch laptop bag and includes a built-in kickstand for stable tabletop play. With its integrated screen, speakers, ports, and compact form factor, it represents a fully self-contained gaming system. This achievement aligns with trends in portable electronics where miniaturization is a key driver for consumer appeal (Source: cooliance.com).
The only notable weak point is the audio quality, with the laptop-style speakers delivering somewhat tinny sound. However, this issue can be immediately resolved with headphones or external speakers—a simple workaround that Tera plans to address in future iterations.
Conclusion
Tera’s portable PS5 demonstrates that Sony’s oversized design may have been more conservative than necessary. While the original PS5’s bulk serves a purpose, this modification proves that innovative engineering approaches can create truly portable gaming experiences without sacrificing performance. Tera’s work not only challenges conventional design wisdom but also opens possibilities for more portable, custom-built gaming solutions in the future. It’s a reminder that sometimes the best way to advance technology is by taking it apart and reimagining it entirely.
