The Highest PC Build EVER - World Record

TL;DR

Linus and Elijah build a power-efficient gaming PC at 40,000 feet on a private jet to claim the world record for highest PC build.

Key Points

• 1.The build was optimized for power efficiency, not raw performance. The system targets ~250W total draw using a Ryzen 5 9600X CPU (tuned down to 45W TDP) and an MSI Ventus RTX 5060 Ti (180W TDP, further undervolted) for maximum FPS-per-watt.
• 2.The only AC power source on the plane is a single kettle outlet. The jet's inverter has just 960W total capacity shared across galley appliances, leaving almost no headroom — forcing the team to cable-run past a sleeping passenger.
• 3.The Fractal Design Terra case was accidentally left on the ground. The crew had to scramble to find it in the cargo hold, and it ultimately didn't fit in the intended under-seat storage location anyway.
• 4.The plane's Wi-Fi was too slow to download games or run a speed test. Fed by ground towers with constant handoffs mid-flight, speeds were so poor even Speedtest.net and fast.com failed to load, limiting them to offline gaming.
• 5.DLSS 4 upscaling on the RTX 5060 Ti made Cyberpunk playable at altitude. Despite visible artifacts, 1% lows held around 75–80 FPS in low-power mode, and the team declared no competing GPU matches its frames-per-watt ratio.
• 6.CPU temperatures dropped significantly after power-limiting to 45W. Thermals fell from 90°C+ to ~70°C using the Noctua NH-L9AM5 cooler, though GPU power consumption barely changed even after applying a custom undervolting curve.
• 7.The build references the legendary 1999 San Antonio Spurs gaming-on-a-plane photo. Linus states the team wants to recreate that iconic image, framing the whole stunt as a world record for the highest altitude PC assembly ever performed.
