The ROG Ally X is ASUS’s flagship handheld gaming PC — a full Windows machine that plays your entire PC game library, runs Xbox Game Pass natively, and fits in your hands. Unlike the Steam Deck, it does not require Linux knowledge or compatibility workarounds. Every game that runs on Windows runs on the ROG Ally X, out of the box. That is its core promise, and this guide covers everything you need to get from unboxing to your first game session as quickly and smoothly as possible. For a broader look at the handheld gaming landscape in 2026, see our complete handheld PC gaming guide.
What Is the ROG Ally X?
The ROG Ally X is the upgraded version of ASUS’s original ROG Ally, launched as a direct competitor to the Steam Deck and Lenovo Legion Go in the growing handheld PC gaming market. Where the original Ally was a strong first attempt, the Ally X addresses the two biggest criticisms — battery life and RAM — by doubling both. The result is the most capable handheld gaming PC available at its release price point.
We cover the exact settings in hades steam deck settings to maximise performance.
The hardware that makes this possible:
| Spec | ROG Ally X | Why It Matters |
|---|---|---|
| Processor / APU | AMD Ryzen Z1 Extreme | 8 cores, 16 threads, 12 RDNA 3 compute units — the same chip family that powers the Steam Deck OLED’s closest rivals |
| RAM | 24GB LPDDR5X | Double the original Ally’s 16GB; the GPU shares this pool, so more RAM means more VRAM headroom for demanding games |
| Storage | 1TB M.2 NVMe SSD | User-replaceable; fast enough for direct NVMe speeds without load-time bottlenecks |
| Display | 7-inch FHD IPS, 120Hz | 1080p at 120Hz is the key display advantage over Steam Deck’s 800p panel |
| Battery | 80Whr | Up from 40Whr on the original Ally; closer to Steam Deck OLED’s 50Whr in real-world runtime |
| OS | Windows 11 Home | Full Windows — every launcher, every game, Xbox Game Pass natively |
| Connectivity | USB-C (2x), Wi-Fi 6E, Bluetooth 5.3 | Dual USB-C enables simultaneous charging and peripheral connection |

Unboxing and First Boot
The ROG Ally X ships with the device, a 65W USB-C charger, a protective case, and documentation. The charger is adequate for daily use but slow for gaming while charging — see the charging section below for why 100W is the practical upgrade.
On first boot, Windows 11 runs through its standard out-of-box experience (OOBE). Complete the Microsoft account login and regional settings as normal — do not skip this. Once at the Windows desktop, the priority order is:
- Charge to 100% before doing anything else. The battery may arrive partially depleted. Calibrating from a full charge gives Armoury Crate accurate battery data from the start.
- Run Windows Update immediately. Go to Settings → Windows Update → Check for Updates. Install all available updates. This can take 20–40 minutes on first run. Do not skip — updates include security patches and driver compatibility fixes that ASUS has validated against the ROG Ally X hardware.
- Update Armoury Crate SE. Open Armoury Crate SE from the taskbar or Start Menu. It will prompt for its own update — install it. The initial Armoury Crate version on shipped units is often several releases behind the current build.
- Install ROG driver package. Armoury Crate SE includes a driver installation section. Run the full ROG driver scan and install any flagged driver updates — this covers the GPU driver, audio, and Ally-specific firmware.
Armoury Crate SE: The ROG Control Hub
Armoury Crate SE is the ROG-specific system overlay that sits on top of Windows. It replaces Steam’s Quick Access Menu as the primary control interface and handles performance mode switching, TDP adjustment, fan curves, RGB lighting, and the game library. Access it at any time by pressing the ROG button (the small button above the right thumbstick).
The interface has four main sections:
- Home: System overview, temperature readouts, and quick performance mode toggle. This is where you spend most of your time.
- Library: Armoury Crate aggregates games from all installed launchers — Steam, Xbox, Epic, GOG — into a single unified game list. You can launch any game directly from here.
- Settings: Per-game performance profiles, fan curve customisation, controller mapping, and display settings.
- Aura: RGB lighting control for the ROG logo on the back panel — functional but purely cosmetic.
The most important Armoury Crate feature is the per-game performance profile system. You can set a different TDP, performance mode, and fan curve for each game — so a light indie game runs in Silent mode automatically while a demanding AAA title triggers Performance mode on launch. Set these profiles as you add games and the device manages itself.
Performance Modes Explained
The ROG Ally X has three system-wide performance modes. Understanding when to use each is the single most impactful setup decision for battery life and performance balance:
| Mode | TDP | Best For | Battery Impact |
|---|---|---|---|
| Silent | 9W | Light games, indie titles, visual novels, emulation. Also useful for Windows tasks, video streaming, and remote play. | Best battery life — roughly 3–4 hours on lighter loads. Fan is near-silent. |
| Performance | 15W | Daily driver for most games. Handles mid-tier titles at playable frame rates and provides headroom for AAA games at lower settings. | Approximately 2–2.5 hours of gameplay. This is the default starting point. |
| Turbo | 25W | Demanding AAA titles, anything that needs maximum GPU throughput. The ROG Ally X can sustain 25W due to the improved thermal design. | Approximately 1–1.5 hours. Fans are audible. Use with a charger nearby when practical. |
The practical recommendation: start in Performance mode for every new game and drop to Silent if the game runs comfortably. Only switch to Turbo for titles where Performance mode causes noticeable frame rate drops in demanding scenes. Turbo is most useful when docked or near a power outlet.
Windows Handheld-Specific Tips
Windows was not designed for handheld gaming, but a handful of tweaks make it significantly more comfortable:
Disable Xbox Game Bar. Go to Settings → Gaming → Xbox Game Bar and toggle it off. Game Bar and Armoury Crate SE both try to intercept the same button shortcuts, causing conflicts. Disabling Game Bar removes the source of the conflict and eliminates background resource usage.
Getting the right settings makes a big difference — see settings helldivers pc for the optimal config.
Set the Windows power plan correctly. Go to Settings → Power & sleep → Power mode and set it to “Balanced”. Do not use “Best power efficiency” — this throttles the CPU even when the device is plugged in. Armoury Crate’s performance modes override Windows power settings for gaming, but Balanced ensures Windows itself does not add unwanted throttling outside of games.
Disable unnecessary startup programs. Open Task Manager → Startup apps and disable anything you do not use daily. The ROG Ally X ships with several ASUS utilities pre-installed. Keep Armoury Crate SE and the ROG system tray tool; disable everything else unless you have a specific need for it.
Update GPU drivers independently. After the initial ROG driver package install, check AMD’s website for the latest Radeon Software for the Z1 Extreme. AMD releases driver updates more frequently than ASUS ships ROG package updates, and newer Radeon drivers sometimes include significant performance improvements for specific games.
Enable auto-HDR (optional). Windows 11 includes Auto HDR, which adds HDR-like tone mapping to SDR games. The ROG Ally X display supports HDR — enable it in Settings → System → Display → HDR for a noticeable visual improvement in compatible titles.
Xbox Game Pass: The ROG Ally’s Killer Feature
The most compelling reason to choose the ROG Ally X over the Steam Deck is Xbox Game Pass. Because the ROG Ally X runs full Windows, the Xbox app installs and runs natively — giving you access to hundreds of Game Pass titles the moment you subscribe. The Steam Deck runs Linux (SteamOS) and cannot run the Xbox app without workarounds that are technically complex and unsupported.
To set up Game Pass on the ROG Ally X:
- Open the Microsoft Store and search for “Xbox” — install the Xbox app if it is not pre-installed.
- Sign in with your Microsoft account.
- Subscribe to Xbox Game Pass Ultimate (the PC tier works but Ultimate adds cloud gaming and console cross-progress).
- Browse the Game Pass library and install games directly. Games install to whichever drive you select — use the internal SSD for best load times, or a fast microSD card for expanded capacity.
In Armoury Crate SE’s Library, Game Pass titles appear alongside Steam and Epic games once installed. You can set per-game performance profiles for Game Pass titles exactly as you would for Steam games.
Epic Games and Other Launchers
Because the ROG Ally X is a full Windows PC, every launcher that runs on desktop Windows installs without modification: Epic Games Launcher, GOG Galaxy, EA App, Battle.net, and Ubisoft Connect all work natively. Download and install them from their respective websites or the Microsoft Store.
For launcher management in the Armoury Crate SE library, the aggregation feature automatically detects most major launchers. If a launcher’s games are not appearing, open Armoury Crate SE → Settings → Library → Scan for games and run a manual scan. This refreshes the detection across all installed launchers.
One practical note: multiple launchers running simultaneously consume RAM and CPU background resources. On the ROG Ally X’s 24GB pool this is not a serious concern, but setting launchers to not auto-start (disable in each launcher’s settings) and launching them on-demand keeps the background load clean.
Controller Mapping in Windows
Windows recognises the ROG Ally X’s controller as an Xbox controller by default. This means any game with Xbox controller support works immediately, with no configuration required. The face buttons, triggers, bumpers, D-pad, and thumbsticks all map to the standard Xbox layout.
For per-game customisation, Armoury Crate SE’s controller mapping tool lets you reassign any button on a per-game basis. This is particularly useful for games with suboptimal default controller layouts. Open Armoury Crate SE → Settings → Key Mapping → select your game and create a custom profile.
Getting the right settings makes a big difference — see poe2 settings pc for the optimal config.
The ROG Ally X also includes back paddle buttons (M1 and M2 on the underside of the grip). These default to unmapped. Assign them to your most-used actions — common choices are dodge, sprint, or quick inventory — via the Key Mapping section. The paddles are a meaningful ergonomic upgrade once you build muscle memory for them.
Docked Mode Setup and the ROG XG Mobile
USB-C docking: Connect any USB-C hub or dock to either of the ROG Ally X’s USB-C ports to add a monitor, keyboard, mouse, and wired internet simultaneously. The device outputs video via DisplayPort Alt Mode over USB-C. Any USB-C dock with DisplayPort support works. When docked, switch to Turbo mode and plug in to power — thermal and battery constraints no longer apply and the hardware runs at full capability.
ROG XG Mobile eGPU (optional upgrade): The ROG XG Mobile is ASUS’s proprietary external GPU enclosure, connecting via the ROG Ally X’s XG Mobile interface port (the dedicated connector on the right side of the device). It houses a discrete NVIDIA or AMD GPU in a compact chassis and delivers a substantial performance uplift for home desk sessions — roughly doubling GPU performance for the most demanding titles.
Getting the right settings makes a big difference — see gtx 1650 1660 settings for the optimal config.
The XG Mobile is a significant additional cost and makes sense primarily for users who want the ROG Ally X to serve as both a portable handheld and a capable home gaming machine without a separate desktop PC. For portable-only use cases, it is unnecessary.
Battery Optimisation and Charging
The ROG Ally X’s 80Whr battery is the largest upgrade over the original Ally, but Windows’s default power behaviour can undercut the improvement. The primary battery drain on Windows handhelds is not the GPU — it is Windows background processes, high-performance power plans, and always-on connectivity.
We cover the exact settings in rog ally accessories to maximise performance.
For maximum battery life away from power:
- Use Silent mode for lighter games and non-gaming tasks
- Enable Airplane Mode during single-player sessions where internet is not needed
- Reduce screen brightness to 50–60% — the display is a significant power draw at full brightness
- Set the FPS limit in Armoury Crate SE — uncapped frame rates burn more power than a locked 30 or 60 FPS even if the game is running at 80 FPS
Charging: The included 65W charger charges the ROG Ally X fully in approximately 2 hours and will maintain charge during gaming at Performance mode. For Turbo mode gaming while charging, a 100W USB-C PD charger is recommended — the 65W charger may see the battery drain slowly during sustained Turbo sessions because charging input does not fully offset 25W draw. Any USB-C PD charger rated 100W from a reputable manufacturer works.
Thermal Management
The ROG Ally X runs hot under sustained load — this is expected behaviour for a device pushing 15–25W through a compact chassis. Normal operating temperatures:
- CPU/APU (gaming, Performance mode): 75–90°C. Normal range.
- CPU/APU (gaming, Turbo mode): 85–95°C. Normal. ASUS validates sustained operation at these temperatures.
- Chassis surface (rear, near vent): Warm to the touch. The exhaust vent on the back of the device expels hot air; avoid blocking it.
For extended desk sessions, a passive cooling stand elevates the device and improves airflow to the rear vent. This alone can reduce APU temperatures by 5–8°C under sustained load. The stand is an inexpensive accessory worth having if you frequently play at a desk in Turbo mode.
Do not place the ROG Ally X on soft surfaces (sofa cushions, blankets, pillows) during gaming — the rear vent requires clear airflow. Hard, flat surfaces are fine without a stand.
microSD Card Setup
The ROG Ally X accepts microSD cards via the slot on the top edge of the device. For game storage, use a microSD card rated A2 (Application Performance Class 2) — this rating indicates random read/write performance adequate for game loading, not just sequential video transfer speed. A1-rated cards are slower and cause noticeably longer load times in open-world games.
Speed class UHS-I U3 or UHS-II is recommended. After inserting the card, Windows formats it via File Explorer — right-click the card and format as exFAT (the default) or NTFS. NTFS is preferable for large game files above 4GB since exFAT has a 4GB file size limit.
Recommended First Software Installs
Beyond the major launchers, these tools improve the ROG Ally X experience significantly:
- HWINFO64: System monitoring that shows real GPU and CPU temperatures with more detail than Armoury Crate SE’s built-in overlay. Useful for diagnosing thermal issues.
- MSI Afterburner: Frame rate overlay and GPU monitoring. Works alongside Armoury Crate SE.
- VLC or MPC-HC: Local video playback for films and media during travel at Silent mode power draw.
- 7-Zip: For extracting game files and mods delivered as archives.
- GeForce NOW or Xbox Cloud Gaming (via browser): Cloud gaming as a battery-saving option for demanding titles you want to play at low power draw.
Common ROG Ally Problems and Fixes
Armoury Crate SE crashes or does not open. This is the most commonly reported issue with the ROG Ally X. Fix: Open Task Manager, find all Armoury Crate processes and end them, then relaunch from the Start Menu. If the problem persists, run the ASUS uninstall tool from their support site and reinstall the latest version of Armoury Crate SE from scratch.
Windows Update breaks Armoury Crate SE or ROG drivers. A known issue where certain cumulative Windows updates conflict with ASUS’s driver package. Fix: After a problematic update, run the ROG driver scan in Armoury Crate SE → Settings → System Update. If Armoury Crate itself is broken, download the ROG Ally driver package directly from the ASUS support page for your device model.
Controller not detected in a game. Cause: the game expects a DirectInput controller and the ROG Ally X registers as XInput. Fix: in Steam, enable “PlayStation Controller Support” or “Generic Gamepad Configuration Support” in Steam’s controller settings — Steam’s controller translation layer converts XInput to whatever the game expects. For non-Steam games, try running them via Steam as a non-Steam game to gain access to this translation.
Controller deadzone drift (thumbstick registers movement at rest). Fix: Open Armoury Crate SE → Settings → Key Mapping → Deadzone and increase the deadzone threshold slightly. A value of 8–10% typically eliminates perceived drift without affecting responsiveness in fast-paced games.
MicroSD card not appearing in Windows. Fix: Remove and reinsert the card with the device powered on. If still not detected, check that the card is fully seated — the slot requires firm pressure until you feel a click. Format the card via Disk Management if Windows sees the hardware but not the partition.
Frequently Asked Questions
Is the ROG Ally better than the Steam Deck?
It depends on your priority. The ROG Ally X outperforms the Steam Deck OLED in raw GPU performance, display resolution (1080p vs 800p), RAM, and Game Pass native compatibility. The Steam Deck OLED has a superior OLED display (better contrast, colours), longer battery life at equivalent gaming loads, a more optimised and stable SteamOS experience with no Windows maintenance overhead, and a lower entry price. If Xbox Game Pass access and maximum PC gaming compatibility matter most, the ROG Ally X wins. If you want a simpler, longer-lasting handheld with a better screen, the Steam Deck OLED wins. See our full Steam Deck vs ROG Ally vs Legion Go comparison for a detailed breakdown.
What is the ROG Ally X battery life?
In Silent mode with light games, approximately 3–4 hours. In Performance mode with mid-tier games, approximately 2–2.5 hours. In Turbo mode with demanding AAA titles, approximately 1–1.5 hours. Screen brightness and Wi-Fi activity also affect these figures — Airplane Mode and 50% brightness can add 20–30 minutes to any scenario. The 80Whr battery is a significant improvement over the original Ally’s 40Whr, but Windows’s background power demands mean real-world figures are typically lower than Steam Deck in equivalent gaming scenarios.
How do I install games on the ROG Ally X?
Through any Windows game launcher: Steam, Xbox Game Pass, Epic Games, GOG Galaxy, EA App, Battle.net, or Ubisoft Connect. Install the launcher from its website or the Microsoft Store, sign in, and download games as you would on a desktop PC. For storage management, the 1TB internal SSD handles most libraries; add a fast microSD card (UHS-I U3 or UHS-II, A2-rated) for expanded capacity. Armoury Crate SE’s Library section aggregates games from all launchers into a single interface once detected.
