Low-power mini PCs have become genuinely capable casual-gaming machines in 2026, but “low power” needs context. A processor’s TDP is not the same thing as total wall power, and performance modes can change consumption dramatically.
For gaming without a discrete desktop GPU, three current options stand out: the MINISFORUM X1 Lite, MINISFORUM UM890 Pro, and ASUS NUC 14 Pro AI.
| Mini PC | Best for | Integrated graphics | CPU power class |
|---|---|---|---|
| MINISFORUM X1 Lite | Best value | Radeon 780M | Up to 65W configured performance |
| MINISFORUM UM890 Pro | Best upgrade flexibility | Radeon 780M | Ryzen 9 8945HS class |
| ASUS NUC 14 Pro AI | Best very-low-power premium option | Intel Arc 140V / 130V | 30W cTDP |
1. MINISFORUM X1 Lite: best value
The X1 Lite pairs an AMD Ryzen 7 255 with Radeon 780M integrated graphics.
MINISFORUM lists dual-channel DDR5-5600, two PCIe 4.0 M.2 slots, 2.5Gb Ethernet, USB4 and an OCuLink option. The system is compact at roughly 130 × 126 × 47mm.
The company configures the cooling for up to a 65W TDP performance mode, so this is not a 10-watt fanless box — but it remains dramatically smaller and lower-power than a typical desktop gaming tower.
See current X1 Lite specifications.
2. MINISFORUM UM890 Pro: best upgrade flexibility
The UM890 Pro uses the Ryzen 9 8945HS with Radeon 780M graphics and supports up to 96GB of DDR5 memory.
Its main advantage is expansion: dual M.2 storage, USB4, dual 2.5Gb Ethernet and a native OCuLink interface make it much easier to add fast storage or an external GPU later.
See MINISFORUM UM890 Pro specifications.
3. ASUS NUC 14 Pro AI: best very-low-power premium option
The ASUS NUC 14 Pro AI is built around Intel Core Ultra Series 2 processors with a 30W configurable TDP.
Core Ultra 7/9 variants use Intel Arc 140V integrated graphics, while Core Ultra 5 versions use Arc 130V. ASUS also includes Wi-Fi 7, 2.5Gb Ethernet and Thunderbolt 4.
This is the strongest fit here if low platform power and a tiny footprint matter more than maximum integrated-GPU performance.

What games can integrated graphics actually handle?
Modern Radeon 780M/890M and Intel Arc integrated graphics are well suited to:
- indie games;
- older AAA titles;
- League of Legends, Dota 2 and similar esports games;
- Minecraft and The Sims 4;
- emulation; and
- modern games at reduced resolution/settings where performance is adequate.
Do not assume every new AAA release will deliver 60fps at 1080p high settings. Integrated graphics share system memory and have much less power/thermal headroom than a desktop graphics card.
Dual-channel memory matters
Integrated GPUs depend heavily on system-memory bandwidth.
A mini PC with one memory module can perform significantly worse than the same system using a proper dual-channel configuration. When buying barebones, install matched memory modules unless the platform uses soldered high-bandwidth memory by design.
TDP is not wall power
The old article compared fixed “45W mini PC” and “350W desktop” figures as though they represented universal wall consumption. They do not.
TDP/cTDP describes a processor power/thermal operating target, not the complete PC’s electricity draw. Storage, memory, cooling, peripherals and power-supply losses all add to wall power.
If efficiency matters, measure the actual configured system with a wall power meter under the workloads you use.
What about Radeon 890M?
Radeon 890M systems such as MINISFORUM’s AI X1 Pro-370 provide stronger integrated graphics than 780M-class machines, but they are also significantly more expensive and can operate at higher platform power.
That makes them attractive for performance-first compact gaming, but less obvious as a “low-power casual gaming” recommendation.
Can you add a GPU later?
Some mini PCs now include OCuLink or USB4, which can be used with external GPU docks.
OCuLink generally provides a more direct PCIe connection than USB4/Thunderbolt, but adding an external GPU also adds a separate power supply, enclosure/dock and much higher total system power.
Windows 11, Linux and SteamOS-like setups
Windows remains the easiest option for broad game compatibility, anti-cheat support and driver tools.
Linux can work very well for Steam-heavy libraries, but game compatibility varies. Check the exact games you care about before buying a mini PC specifically for Linux gaming.
How much RAM?
16GB is the practical minimum for a gaming-focused mini PC in 2026; 32GB is preferable if the integrated GPU reserves several gigabytes of system memory or you multitask heavily.
Quick answer
Choose MINISFORUM X1 Lite for value, UM890 Pro for stronger expansion and eGPU options, or ASUS NUC 14 Pro AI when low platform power and compactness are the priority. For serious AAA gaming, a system with a discrete GPU remains the better choice.
