⚙️ Technical Specifications Sheet

🧱 Design and Construction Quality

The MLLSE G5 Pro uses a compact chassis with identical dimensions to the M6 ​​model ( 114 × 106 × 42.5 mm ), taking up less than half a liter of volume on the desktop.

The exterior combines a robust, matte black frame with perforated grilles on the sides and back. Users who have received it highlight that the device feels solid, well-assembled, and not at all flimsy.

One aspect highly praised by the community, contrary to certain internet myths, is its ease of opening: you only need to remove 4 screws located under the lower rubber feet to immediately access the two SO-DIMM RAM memory slots and the single M.2 SSD socket.

🖥️ Screen and Multimedia Experience

In terms of image and sound, this small computer stands out for its ability to power three 4K 60Hz displays simultaneously and independently:

• Output distribution: It has 2 full-size HDMI 2.0 ports and 1 front USB Type-C port with native support for DisplayPort video output (DP Alt Mode).

• Multimedia performance: The integrated AMD Radeon graphics handle Ultra HD resolutions with absolute ease, both on the desktop and when streaming video (YouTube 4K, Netflix or local players like VLC).

• User experience: Buyers who have connected it to large-format TVs in the living room note that it is a perfect machine for streaming from a main desktop PC using Moonlight, Steam Link or Sunshine, handling 4K resolutions at 60 FPS with minimal decoding latency.

⚡ Performance, Software and Storage

The real strength of the MLLSE G5 Pro lies in the power of its AMD Ryzen 7 5800H processor. Unlike chips that combine slow and fast cores, this one boasts eight full high-performance Zen 3 cores capable of processing 16 threads simultaneously.

Operating system and startup

The computer comes with Windows 11 Pro pre-installed but not initialized, meaning that upon first use, the user is immediately greeted by the official Microsoft setup wizard (OOBE) to choose language, account, and personal preferences. The units received by buyers confirm 100% new components: analysis with CrystalDiskInfo reveals drives with only 10-11 factory boot cycles resulting from quality control testing.

Internal storage speeds

The standard 512GB drive comes installed in its M.2 slot using SATA3 bus. Real-world tests recorded with CrystalDiskMark yielded the following results:

• Sequential Read (SEQ1M Q8T1): 549.04 MB/s

• Sequential Read (SEQ1M Q1T1): 529.60 MB/s

• Sequential Write (SEQ1M Q8T1): 422.61 MB/s

• Sequential Write (SEQ1M Q1T1): 411.12 MB/s

• Random Read (RND4K Q32T1): 218.50 MB/s

• Random Write (RND4K Q32T1): 207.30 MB/s

Although these figures are more than enough for the system to boot in about 12 seconds and office tasks to feel instantaneous, this unique M.2 slot is of a hybrid type: it is compatible with both the SATA standard and the high-speed PCIe NVMe protocol, allowing you to replace the original drive with a 1 TB or 2 TB NVMe drive to multiply transfer rates by higher speeds.

🔌 Energy Consumption and Cables

Despite using a 45W H-series chip, TSMC's 7nm lithography for AMD provides remarkable power efficiency:

• Standby/Idle Desktop: Ranges between 9W and 13W.

• Office use and web browsing: Between 22W and 35W.

• Rendering load or heavy games: It stabilizes around 48W – 58W, with occasional peaks of up to 65W during the first few seconds of boost.

The transformer included in the box (19V) provides enough headroom to keep the equipment powered along with several hard drives or peripherals connected to its USB ports.

🌡️ Temperature and Noise: Actual Thermal Behavior

The thermal aspect is the point where real user reviews most agree, and it's important to be completely transparent about it:

• Improved copper heatsink: The manufacturer has incorporated a pure copper radiator assisted by multiple air openings in the casing to keep the 8 cores of the Ryzen 7 under control.

• Chassis temperature: At idle, the CPU temperature remains between 45°C and 52°C. During sustained demanding tasks, the internal temperature rises to 82°C–86°C. The mini PC's body feels warm to the touch, but not to extreme levels that would compromise the circuitry.

• Fan noise level: As reported by AliExpress buyers: "The fan is noisy, it activates automatically and blows strongly. The chassis is always warm, but not alarmingly so." When the processor is under heavy load, the small turbine accelerates decisively to expel the hot air. For light tasks or watching a movie, it remains at a moderate level, but if you're going to be rendering video or playing games daily, you'll hear a constant and noticeable airflow on the desktop.

🌐 Connectivity and Ports

The port distribution in this model is extremely balanced:

• Front panel:

  • 1x Multifunction USB Type-C Port (DisplayPort video output + data transfer)

  • 2x High-speed USB 3.0 Type-A ports

  • 1x 3.5mm combo audio jack connector

  • Power button with integrated LED

• Rear panel:

  • 2x HDMI 2.0 video outputs (4K at 60 Hz)

  • 1x USB 3.0 Type A Port

  • 1x USB 2.0 Type A port (ideal for mouse and keyboard receiver)

  • 1x RJ45 Gigabit Ethernet network port (1000 Mbps)

  • 1x DC Power In (19V)

• Wireless section: It incorporates a card with Wi-Fi 6 and Bluetooth 5.2, offering great coverage and connection stability without the need for network cables.

🛠️ Expansion and Upgrades: What Can We Improve?

The MLLSE G5 Pro's motherboard allows for upgrading its key components, with one important feature being storage:

• RAM: It has two DDR4 SO-DIMM slots. The stock configuration includes 16 GB at 3200 MHz. The motherboard supports modules up to 32 GB per slot, allowing for a maximum of 64 GB of RAM in dual channel for users working with virtual machines, heavy analytics, or intensive editing.

• SSD Storage (Single Slot): The computer has only one M.2 2280 slot, which comes pre-installed with a 512 GB drive. This slot is compatible with both SATA and PCIe NVMe (Gen3/Gen4) protocols, supporting drives up to 1 TB or 2 TB. To expand storage capacity, a second internal drive cannot be added; the original 512 GB drive must be removed and replaced with the new SSD (after cloning the system or performing a clean installation of Windows).

💡 Pro upgrade tip:
With only one M.2 slot, the best investment if you need more space or speed is to replace the stock SATA drive with a 1TB or 2TB M.2 2280 NVMe PCIe SSD, which will increase read/write speeds sixfold and unleash the full potential of the Ryzen 7 processor.

🛒 If you want to upgrade your mini PC with the best prices and offers:

• You can purchase a 3200 MHz DDR4 SO-DIMM RAM memory module to upgrade your system to 32 GB or 64 GB.

• Or buy a high-speed M.2 NVMe PCIe SSD (1 TB or 2 TB) to replace the original drive and speed up the system.
