Short answer: SteamOS is no longer exclusive to the Steam Deck. Lenovo’s Legion Go S became the first third-party handheld officially licensed to ship with Valve’s operating system, and Lenovo now markets SteamOS configurations for the Legion Go 2. However, Valve’s own support page currently lists only Steam Deck and Legion Go S as officially supported devices. Other AMD handhelds may boot or install SteamOS, but “works” is not the same as licensed, certified or fully supported.
Valve announced the expansion on January 7, 2025, promising better compatibility for additional handheld PCs. The rollout has begun, but it remains controlled rather than universal.
SteamOS hardware status at a glance
| Device | Ships with SteamOS? | Valve’s current official status | What buyers should know |
|---|---|---|---|
| Steam Deck | Yes | Officially supported | Valve’s reference platform and most mature SteamOS experience. |
| Lenovo Legion Go S SteamOS edition | Yes | Officially licensed and listed by Valve | First third-party handheld in the program; Lenovo provides device-specific support and installation documentation. |
| Lenovo Legion Go 2 | Lenovo markets SteamOS configurations | Not listed on Valve’s current support page | Announced and marketed by Lenovo, but verify the exact model and Valve’s support list before buying. |
| Original Legion Go, ASUS ROG Ally/Ally X and similar AMD handhelds | Not generally preinstalled | Compatibility may be improving, but not blanket official support | Installation can involve missing controls, power features, firmware support or sleep problems. |
| Intel- or Nvidia-based handhelds | Not established | Do not assume support | Valve’s current expansion language specifically emphasizes AMD-powered handheld PCs. |
Valve’s current SteamOS page names only Steam Deck and Lenovo Legion Go S as officially supported, while saying compatibility with other AMD handhelds is improving.
What Valve actually announced
In its January 7, 2025 announcement, Valve called the Legion Go S the first handheld officially licensed to ship with SteamOS. It also said work on that device would improve the operating system on other handheld PCs.
#1 Best Overall
- 1TB NVMe SSD
- 1280 x 800 HDR OLED display with premium anti-glare etched glass, 7.4" Diagonal display size up to 90Hz refresh rate
- Wi-Fi 6E
- 50Whr battery; 3-12 hours of gameplay (content-dependent)
- Carrying case with removable liner
That wording matters because several different claims are often collapsed into “official SteamOS support”:
- Officially licensed hardware: the manufacturer worked with Valve and can use SteamOS branding.
- Officially supported by Valve: Valve’s own support materials identify the model.
- Manufacturer installation image: the maker supplies a recovery or installation process.
- Community-compatible: users have made SteamOS-like software work, without a Valve or manufacturer promise.
- Boots successfully: the system starts, but controls, audio, Wi-Fi, sleep, firmware or power management may still be incomplete.
Valve’s FAQ also explains that redistribution of the Steam Client, SteamOS branding and Valve trademarks requires a license. The open-source Linux components underneath do not make every compatible handheld an official SteamOS product.
Legion Go S: the first real SteamOS alternative to Deck
The Legion Go S is the clearest non-Deck choice for readers who want a manufacturer-backed SteamOS handheld. Lenovo published a SteamOS edition announcement and a dedicated FAQ, while Valve includes the model in its official support list.
It still is not simply a Steam Deck with different plastic. Hardware-specific integration can differ in button labels, gyro behavior, fan controls, charging limits, docking, external displays, SD-card behavior and sleep/wake reliability. Lenovo’s FAQ warns that shortcut labels may not perfectly match the physical layout because SteamOS was not fully customized for every button arrangement.

Legion Go 2: announced SteamOS hardware, narrower Valve confirmation
Lenovo announced a Legion Go 2 SteamOS configuration, and Lenovo’s product pages list SteamOS among the available operating-system options. Its US Legion Go Gen 2 information describes configurations with up to an AMD Ryzen Z2 Extreme, 32 GB of memory, 2 TB of storage and a 74-Wh battery; the retrieved page showed a $1,099.99 starting-price signal for that product family. Model, region and configuration limits apply.
Those are Lenovo’s product claims, not a replacement for Valve’s support list. The Valve page currently retrieved still lists only Steam Deck and Legion Go S. Treat Legion Go 2 as announced or marketed SteamOS hardware until Valve separately confirms its support status, and check that a retailer’s exact SKU is the SteamOS model rather than Windows.
What SteamOS gives you on a handheld
Valve describes SteamOS as a Linux-based system built around gamepad control. Its Steam layer provides access to the Library, Steam Cloud, Steam Chat, Game Recording, quick suspend/resume and built-in updates, while desktop mode lets you install other software.
- A controller-first interface instead of a Windows desktop interrupting handheld play.
- A unified Steam library and Steam Input configuration system.
- Console-style suspend and resume on supported hardware.
- Desktop mode for browsers, files and additional applications.
These are platform goals, not a guarantee that every non-Deck device will have identical power management or performance. Valve also says users should not treat SteamOS as a replacement for a general desktop operating system.

Game compatibility: broad, but not universal
Windows games run through Proton, Valve’s compatibility layer. Valve’s SteamOS page reported more than 18,000 titles checked when that page was published, but the number is a changing snapshot rather than a permanent guarantee.
- Verified: Valve considers the game suitable for the target handheld experience.
- Playable or unverified: it may work, but could need control, graphics or launcher adjustments.
- Unsupported: it may fail because of anti-cheat, launchers, video playback, controls or other incompatibilities.
Check the individual game’s current Steam listing and community reports. Proton versions, game patches, anti-cheat systems and launchers can change results without any change to the handheld itself.
SteamOS versus Windows
| SteamOS is stronger when you need… | Windows is stronger when you need… |
|---|---|
| Steam-first, controller-focused navigation | Native PC Game Pass |
| Quick suspend/resume and a console-like shell | Epic, GOG and other Windows launchers with minimal setup |
| Steam Input, Cloud and recording integrated in one interface | Broad driver, peripheral and productivity-software compatibility |
| Fewer Windows desktop and update interruptions | Manufacturer tuning utilities and familiar administration tools |
Epic, GOG and other launchers can often be installed from desktop mode or with third-party tools, but they are less integrated than Steam. Xbox PC Game Pass is the most decisive reason many buyers remain with Windows. Lenovo also says Legion Space is available on Windows models but not SteamOS configurations, and identifies some fingerprint and audio functions as Windows-specific or unavailable on SteamOS editions.

- Valve is entering the gaming console marketplace with the new Steam Deck, a console geared towards PC gamers. The Steam Deck can be docked to a monitor, and used as a PC, or docked to a TV.
- Players can play a huge variety of games at any time with the comfort of a console and the freedom of a PC. Not anti-glare screen.
- Like the name suggests, the Steam Deck will include upgraded 1TB storage, and will include a carrying case. A micro SD slot will also enable expanded storage.
- Valve partnered with AMD to create a specialized APU optimized for handheld gaming, and Valve says the chip will deliver performance to run AAA gaming titles.
- The Steam Deck is outfitted with a 7-inch touchscreen, and two trackpads under the control sticks that allow gamers to operate games never designed outside of mouse and keyboard capabilities.
- Download the correct SteamOS image from Lenovo Support.
- Prepare a USB flash drive with at least 16 GB of capacity.
- Create a bootable installer with Rufus or an equivalent imaging utility. Creating it erases the USB drive.
- Back up files, game saves, Windows recovery media, drivers and firmware tools before changing the internal drive.
- Power the handheld off, boot from the USB drive and enter Lenovo’s SteamOS repair or installation environment.
- Follow the model-specific prompts and confirm whether the process will repartition or overwrite the internal SSD.
This is not a universal recipe for an ROG Ally, original Legion Go or another model. A different image, BIOS boot-menu setting, Secure Boot change, firmware package or manual fix may be required. A device can boot SteamOS while still lacking reliable Wi-Fi, audio, sleep, TDP controls, external-display support, built-in buttons, SD-card access or firmware updates. Keep a Windows recovery path even if the installation succeeds.
Should you buy, wait or use another Linux distribution?
Buy official SteamOS hardware if you…
- Mostly play games from Steam.
- Want controller-first navigation and quick suspend/resume.
- Do not depend on native PC Game Pass.
- Prefer a supported, manufacturer-supplied build over community troubleshooting.
Choose Windows if you…
- Use Game Pass or several PC storefronts regularly.
- Need productivity applications, unusual peripherals or broad driver support.
- Rely on vendor control panels, lighting tools or performance profiles.
Wait if you…
- Want a Legion Go 2 SteamOS model but local availability or Valve support is unclear.
- Need confirmed battery, firmware and suspend behavior rather than launch promises.
- Are unwilling to reinstall an operating system or troubleshoot hardware integration.
Consider Bazzite only when you accept community support
Bazzite can provide a SteamOS-like Linux experience on unsupported hardware, but it is not SteamOS and is not supported by Valve. It suits owners comfortable with updates, workarounds and recovering Windows themselves.
The bottom line
SteamOS has already moved beyond the Steam Deck, beginning with the officially licensed Lenovo Legion Go S. Valve is building a broader handheld platform, but its official hardware list remains much smaller than the number of devices that may boot a compatible Linux image. Buy an official model for the least ambiguity, stay with Windows for launcher and Game Pass flexibility, and treat every other installation as a device-specific experiment until Valve and the manufacturer say otherwise.
