Valve announced in June 2026 that SteamOS is now available for custom desktop PC builds, giving gamers an alternative path to the Steam Machine experience without waiting for a reservation through Valve’s official system.
Starting with SteamOS 3.8, users can install the operating system on self-built PCs using their own choice of components. SteamOS 3.8.10 launched last week and includes improved compatibility with recent Intel and AMD platforms. Installing SteamOS on non-Valve hardware has technically been possible before, but the process required using a Steam Deck recovery image and was largely limited to AMD systems, making it difficult for Intel or Nvidia users.
Valve’s Pierre-Loup Griffais told The Verge that the company has been “rolling out improvements to [SteamOS] so it’s more compatible with desktop hardware.” On Nvidia support specifically, Griffais said Valve has “a growing team” working on Nvidia drivers and is “collaborating with Nvidia very closely,” though he noted that support may not arrive this year.
For now, Griffais says SteamOS should deliver a “good experience” on console-style setups — a PC connected to a TV with a single hard drive, not intended for dual-booting. He described the result as “very similar to a Steam Deck docked or a Steam Machine, with some caveats,” citing the absence of HDMI-CEC support as one example. A full dual-boot install wizard does not yet exist, meaning users who install SteamOS on an existing Windows machine will need to wipe their drive first.
Griffais said he envisions “a time where it’s a better experience to install on your desktop and have it coexist with a different operating system,” suggesting dual-boot support could come in a future release.
For those who prefer to wait for a more polished experience, the source notes that gaming-focused Linux distributions such as Bazzite and Nobara are available as alternatives.
