The mini PC landscape is crowded, with options ranging from ultra-low-power sticks to surprisingly potent gaming boxes. The Mele Overclock X5 carves its niche by blending potent processing power, usually found in larger systems, with an exceptionally slim profile and professional-grade features. Its most significant differentiator is the implementation of the Intel Core i5-12450H processor. While this 12th Gen Alder Lake chip is powerful in its own right, Mele has specifically engineered the Overclock X5’s thermal module to sustain a higher 45W Power Limit 1 (PL1) compared to the standard 35W configuration often seen in similar-sized devices. This “overclock” isn’t about manual user tweaking in the traditional sense, but rather an optimized power delivery and cooling system designed to let the CPU run faster for longer under sustained load.

Beyond raw power, the X5 distinguishes itself with its focus on connectivity and multi-display capabilities within its ultra-compact 0.57-liter chassis. Offering quad 4K display outputs is rare in this size class, making it immediately appealing for productivity setups, digital signage walls, or monitoring stations. The inclusion of dual Ethernet ports, one being a high-speed 2.5GbE port, further caters to users with specific networking needs, such as those using network-attached storage (NAS), running virtual machines, or setting up custom router/firewall solutions. Combined with its VESA mount compatibility and advanced BIOS features, the Mele Overclock X5 positions itself as more than just a general-purpose mini PC; it’s a versatile tool for power users and specific professional applications demanding performance, connectivity, and a minimal footprint.

Unpacking the Performance: How Powerful is the Intel Core i5-12450H in the Overclock X5?

At the heart of the Mele Overclock X5 lies the Intel Core i5-12450H processor. This is a mobile chip from Intel’s 12th Generation “Alder Lake” family, featuring a hybrid architecture: 4 Performance-cores (P-cores) that can boost up to 4.4GHz and 4 Efficient-cores (E-cores) that reach up to 3.3GHz. With a total of 8 cores and 12 threads (P-cores are hyper-threaded, E-cores are not), this CPU is well-equipped for multitasking and demanding productivity workloads. It significantly outperforms older generation i5s and even some i7s from previous generations, offering a substantial leap in both single-core and multi-core performance.

The key performance feature highlighted by Mele is the optimized 45W PL1 configuration. PL1 (Power Limit 1) dictates the sustained power draw the CPU can maintain. By increasing this from the typical 35W to 45W and implementing a cooling solution to handle the extra heat, Mele allows the i5-12450H to maintain higher clock speeds for longer durations under heavy load. Their internal testing claims a 24% improvement in Cinebench R23 multi-core scores (9184 points vs. 7414 points for a 35W system). While benchmark scores provide a good comparison point, this translates to tangible benefits in real-world scenarios like video encoding, running complex spreadsheets, compiling code, or handling multiple virtual machines. The integrated Intel UHD Graphics (48 Execution Units, up to 1.2GHz) are capable for everyday tasks, multimedia playback (including 4K), and light gaming, but aren’t designed for demanding modern AAA titles.

Design and Build Quality: Is the Overclock X5 Truly “Sharp & Slim”?

This makes it significantly smaller than traditional small form factor (SFF) PCs and notably thinner than many popular mini PCs like the Intel NUC or Apple Mac Mini (as highlighted in their comparison graphic). Weighing in at 534 grams (1.18 lbs), it’s lightweight and highly portable. The chassis appears to be constructed primarily from metal, likely aluminum, contributing to a sturdy feel and aiding passive heat dissipation, complementing the internal active cooling fan. The design is minimalist and functional, with clean lines and a dark grey/black finish that should blend easily into most office or home environments.

The slim profile is particularly advantageous for VESA mounting. By attaching the Overclock X5 directly to the back of a monitor using a standard VESA bracket (often included or available separately), you can create an “all-in-one” style setup with zero desk footprint. This is ideal for minimalist desks, kiosks, digital signage installations, or anywhere space is at a premium. The build quality feels solid, appropriate for a device potentially deployed in various environments. While it’s not ruggedized in the military sense, the metal construction and thoughtful port placement suggest durability for typical office or home use. The numerous ventilation grilles on the sides are crucial for the 45W cooling system and indicate that airflow management was a key design consideration.
