📌 If you're interested in an even more powerful version of this same chassis, we've already analyzed the Core i7-14650HX and Core i9-14900HX variants in depth in our full review: ACEMAGIC M5 i7-14650HX Review. There, we compared the three CPU options (i5-14450HX, i7-14650HX, and i9-14900HX) that ACEMAGIC offers for the same Matrix M5 model, in case you're considering upgrading.

The ACEMAGIC M5 with an Intel Core i5-14500HX is, on paper, one of the most powerful mini PCs in its price range: 14 cores, 20 threads, and speeds up to 4.9 GHz in a chassis the size of a paperback book. With the current offer—400 for the 16GB/512GB version or 500 for the 32GB/1TB version—the core-to-price ratio is one of the best we've seen in this segment.

Pros:

• Exceptional multi-core CPU performance for its price (Geekbench 6 multi-core up to 11,871 points on some units).

• Highly expandable: up to 64GB RAM and 4TB SSD in dual M.2.

• Triple 4K real output (HDMI, DP and USB-C) with cooling that prevents aggressive throttling.

• Two budget-friendly configurations: (16GB/512GB) and (32GB/1TB).

Cons:

• Integrated Intel UHD GPU (32 EU) very limited for modern or AAA gaming.

• Build quality and after-sales support below that of Beelink or Minisforum.

• Under sustained load, the temperature can approach 87°C and the fan noise is noticeable (~50 dB under extreme stress).

In short: for 405-512 you get "desktop" CPU power in a tiny chassis, ideal for heavy office work, development, or trading; if you expect to play games properly or need a solid long-term warranty, look at other brands or upgrade to the i7/i9 version we reviewed in our other review.

Table of Technical Specifications

Design and Construction Quality

The chassis is plastic, which is to be expected given the price, and it's especially noticeable when compared to Minisforum's high-end aluminum. Even so, the build quality is adequate for everyday use: there are no creaks or noticeable loose parts. Its pocket-sized design allows it to fit in any corner of the desk, and VESA compatibility is a real plus if you're looking for a minimalist setup with no visible cables or towers.

Screen and Multimedia

The M5 doesn't have its own screen (it's a mini desktop PC), but it stands out for its ability to simultaneously output 4K@60Hz via HDMI 2.0, DisplayPort 1.4, and USB-C with DP Alt-Mode. For 4K video playback, browsing, and office applications across multiple monitors, the experience is smooth and lag-free in both the 16GB and 32GB configurations. Audio is only available via a 3.5mm jack or HDMI/DP, without built-in speakers, so you'll need monitors with built-in speakers or an external sound system.

Performance and Software

Herein lies the true appeal of the M5. As an HX-class chip (originally designed for high-end gaming laptops), its multi-core performance clearly surpasses that of the U/H processors typically found in mini PCs at this price point. It runs Windows 11 Pro out of the box, with enterprise features like BitLocker and Remote Desktop enabled from the first boot.

With 16GB (405€ ($378) configuration) the performance in office tasks, browsing and light development is more than enough, although if you usually have dozens of tabs, Docker or virtual machines open at the same time, you will notice the jump with the 32GB configuration (512€ / 479$), which also comes in dual channel and makes better use of the chip's memory bandwidth.

Regarding bloatware, several reviewers agree that it comes relatively clean, although the general recommendation from the community—which we endorse—is to reinstall Windows from an official Microsoft ISO before daily use, since ACEMAGIC has a history of questionable pre-installed software in previous models.

Energy Consumption and Cables

One of the most outstanding features of the M5 is its efficiency: under full load in Cinebench, consumption remains below 100W, a very reasonable figure for a 55W TDP unlocked chip.

The device is powered by an external power adapter (included in the box), with no additional cabling required beyond the network cable or any peripherals you connect.

Temperature and Noise (Actual Thermal)

This is a section where it is important to clarify depending on the usage scenario:

• Normal use (office applications, browsing, video): very low noise, around 35 dB, barely perceptible in an office or bedroom.

• Under prolonged synthetic stress (Cinebench, renders): the fan speed increases to nearly 50 dB, with a slight buzzing sound that is noticeable but not annoying.

• Temperature spikes under extreme load: occasional spikes of up to 87°C have been recorded in aggressive stress tests, although the reviewers themselves point out that this is a scenario that is not representative of daily use.

The cooling system combines a vapor chamber, copper heat pipes, and aluminum fin heatsinks, specifically designed for HX chips, which explains why it maintains performance without severe throttling in most real-world cases.

Connectivity and Extras

The M5 doesn't include NFC, a fingerprint reader, or IP certification (it's not water or dust resistant), which is understandable for a mini desktop PC at this price point. Its strength lies in its wired and wireless connectivity: WiFi 6E, Bluetooth 5.2 with LE Audio support, Gigabit Ethernet, and a total of 7 physical ports (2 video ports, 6 USB ports of various types and speeds, plus an audio jack), enough for a complete workstation without the need for an external hub. This connectivity is identical in both price configurations.

Expansion and Upgrades

This is one of the real strengths of the M5 compared to mini PCs with soldered memory, and it applies equally to the €405 ($378) version and the €512 ($479) version:

• RAM: The base version comes with 16GB and the recommended version with 32GB of dual-channel DDR4, but the chassis supports up to 64GB of DDR4 by replacing the SO-DIMM modules. 👉 See compatible DDR4 SODIMM RAM modules on AliExpress

• Storage: The M5 features dual M.2 NVMe PCIe 4.0 slots, allowing you to add a second SSD for up to 4TB total storage without sacrificing the original drive. This means that if you buy the €405 version with 512GB, you can upgrade later without having to replace the factory drive. 👉 See the 1TB NVMe PCIe 4.0 SSD on AliExpress

• It does not have an additional 2.5" bay for SATA HDD/SSD; all storage expansion goes through the two M.2 slots.

Comparison with Direct Competitors

We analyzed the i7-14650HX and i9-14900HX versions of this same chassis in detail in our full review of the ACEMAGIC M5 i7-14650HX, where we compared the three CPUs available for this model. If your budget allows and you need more cores for compiling or rendering, that review will help you decide if it's worth paying the price difference compared to this i5 version (€405-€512 / $378-$479).

Technical Tests

For context, the bigger brother of this model —the i7-14650HX, reviewed in our other review— scores 2,664/11,503 points in Geekbench 6 single/multi and 1,943/14,586 in Cinebench R23, with 312 points in 3DMark Steel Nomad Light, confirming that in both cases the integrated GPU is the bottleneck, not the CPU.

The conclusion of these tests is consistent among reviewers: the M5 in any of its three CPUs performs like a mid-to-high-end desktop computer, but its integrated GPU limits it to light graphics tasks.

Final Conclusion

The ACEMAGIC M5 with Intel Core i5-14500HX is a very interesting option if your priority is CPU power at the lowest possible price: perfect for developers, traders, content creators in tasks without GPU intensive, or anyone who needs to run multiple virtual machines or code environments simultaneously.

With the current offer, the €405/$378 version (16GB/512GB) is the best entry-level option, while the €512/$479 version (32GB/1TB) is the one we recommend if you can stretch your budget: the jump in dual-channel RAM is noticeable in any real multitasking task.

It's not the ideal choice if you're looking for gaming, maximum long-term reliability, or robust after-sales support—in those cases, the Beelink SER8 or Minisforum UM890 Pro are safer, albeit slightly more expensive, alternatives. If you need even more cores, check out our review of the i7-14650HX and i9-14900HX versions of the same chassis.

In conclusion: at these prices (€405-€512 / $378-$479), it's worthwhile if you buy with the right expectations.

Ready to take the leap?

If you're looking for maximum CPU power in a compact and expandable mini PC, the ACEMAGIC M5 with i5-14500HX offers one of the best core/price ratios on the market today, with an active offer starting from €405 or $375.
