Are pre-built Steam Machines too expensive? In this video, I build a custom, small form-factor Steam Machine that costs less and packs a serious punch! We are using an awesome Minisforum BD770i mobile motherboard combo featuring an AMD Ryzen 7 7745HX, paired with a used AMD Radeon RX 7600 GPU inside a compact Amazon Mini-ITX case.
Radeon RX 7600: amzn.to/4kp0sWr
Used RX 7600: ebay.us/Bz3on4
Minisforum B770i: amzn.to/4wR0dZe
Sodimm Ram: ebay.us/F9HRWX
M.2 SSD: amzn.to/43qP0BB
550W PSU: amzn.to/43kbmVj
I’ll walk you through the parts used, the official SteamOS installation process, and how to fix a common integrated graphics issue in the BIOS. We’ll also run extensive 1080p, 1440p, and 4K benchmarks against a standard Steam Machine to see exactly what kind of performance uplift we get. Finally, we'll test real-world gameplay in heavy hitters like Cyberpunk 2077, Forza Horizon 6, Spider-Man 2, and more!
