Final user guide and exact SKU list 330 W external adapter and DDR5-6400 CSO-DIMMs and are used instead. No early preliminary PSU value is stored.

Source4Reviewpcgamer.com/hardware/gaming-pcs/steam-machine-review-2026Read 10 October 2026PC Gamer tested the 2 TB Steam Controller bundle. Valve and Tom's Hardware state that the 512 GB and 2 TB models are identical apart from storage, so CPU, GPU, memory and cooling match. The 1440p rows come from PC Gamer's gaming benchmark suite and the Steam Machine is the first entry of each chart. Cyberpunk 2077 uses RT Medium and the review text names FSR Quality with no frame generation for the upscaled run. The review does not name the upscaler for Black Myth: Wukong. Other rows do not state upscaling.8Reviewgamersnexus.net/pre-built-pc/valve-steam-machine-review-gpu-cpu-benchmarks-steamos-test-thermals-noise-and-priceRead 10 October 2026GamersNexus tested the 512 GB model on SteamOS with MangoHud, out of the box. Resolution and settings come from the chart titles. Every row is average FPS. The 1 percent low is stored only where the text states it. Starfield 1% low is 25 FPS (0.1% low 18). Cyberpunk 2077 RT Medium is 22.8 FPS after Valve's last-minute ray tracing patch (20.7 before). Black Myth: Wukong 1080p High raster with Medium RT and FSR Quality is 16.7 FPS after the patch (13.8 before). The Oblivion Remastered text says no upscaling. Other rows do not state upscaling. Rows with SoftwareRT in the preset use software ray tracing and have no ray_tracing flag.
