📋 Key Technical Specifications

🏗️ Design and Construction Quality

The KAMRUI Pinova P2 adopts an ultra-compact form factor that fits in the palm of your hand, with a plastic chassis that feels solid for its price range. The design is understated, lacking flashy RGB lighting (unlike other models from the brand), making it ideal for work environments or meetings. The passive and active cooling system is well-designed: the fan is barely audible during everyday use, although it may become slightly louder under sustained load.

VESA mount compatibility is a very practical feature: you can place it directly behind the monitor and completely free up desk space.

🖥️ Screen and Multimedia

One of the most striking features of this mini PC is its support for three simultaneous 4K displays at 60Hz via HDMI, DisplayPort, and USB-C. This makes it a serious option for professionals who work with multiple monitors: traders, web designers, content managers, or developers.

The integrated AMD Radeon Vega 5 GPU handles 4K UHD video playback, streaming on platforms like Netflix or YouTube 4K, and high-resolution image display smoothly. As for sound, the device doesn't include built-in speakers—as is typical for mini PCs of this type—so you'll need to connect external speakers or headphones via its audio or USB ports.

⚙️ Performance and Software

The AMD Ryzen 3 4300U is a processor from AMD's Zen 2 family that performs smoothly and satisfactorily in everyday use: multitasking with multiple browser tabs, document editing, video conferencing, and multimedia playback without any problems. In Geekbench 6, this processor scores approximately 1,258 points in single-core and 3,363 points in multi-core, respectable performance for its class and a TDP of only 15W.

For gaming, the story changes. The Radeon Vega 5 allows you to play esports titles (League of Legends, CS2 on low settings), retro emulation with RetroArch, and 2D indie games without difficulty. However, modern AAA titles like Cyberpunk 2077 or Hogwarts Legacy will require very low settings and won't reach a stable 60 fps. Windows 11 Pro comes pre-installed with a legitimate license and, according to reviewers, without excessive bloatware.

🔋 Energy Consumption and Cables

With a TDP of just 15 watts, this mini PC is remarkably efficient. It consumes significantly less power than a traditional desktop PC, resulting in lower electricity bills and virtually silent operation at idle.

The device is powered by a standard external power adapter included in the box. There is no built-in battery, so it is a desktop computer that needs to be plugged in to operate.

🔌 Connectivity and Extras

The connectivity of this device is one of its greatest strengths for its price segment:

• 📶 WiFi 6 (802.11ax) — faster and lower latency than WiFi 5

• 🔵 Bluetooth 5.2 — compatible with modern peripherals

• 🌐 Gigabit Ethernet (Wired LAN)

• 🔌 USB 3.2 Gen 2 Type-A and Type-C

• 🖥️ HDMI + DisplayPort + USB-C for triple 4K output

• 💾 2 M.2 slots for expanding storage

• 🎧  3.5mm audio jack

• 🧲 VESA mount included

❌ What it doesn't have: SD card reader, fingerprint reader, IP water resistance certification, 5G, NFC, or Thunderbolt 4. For many office users, this isn't a real problem.

💬 Reviews on Well-Known Pages

This section is key to making an informed decision. Here's a summary of what the community is saying:

🔴 Reddit (r/MiniPCs)

Reddit users highlight that KAMRUI mini PCs with Ryzen processors offer amazing value for money, especially during Amazon sales. One of the most highly rated comments states: "Almost any game I try runs well with a little tweaking of the graphics settings." However, there are also warnings: one user reported that after the unit failed after the one-year warranty expired, the company only offered a third of the original value as compensation instead of repair or replacement, which sparked controversy.

🟡 Trustpilot (kamrui.com)

The KAMRUI brand has a 3.2 out of 5 rating  on Trustpilot, classified as "Average." This isn't a stellar result and reflects some users' complaints about after-sales support. If you highly value technical service, this is something to keep in mind.

🟢 YouTube (Independent Reviewers)

Specialized mini PC channels have given the model positive reviews. One reviewer highlights: "The KAMRUI Pinova P2 delivers impressive performance in an ultra-compact form factor... clearly outperforming chips like the Ryzen 3500U and the Intel N150." Another review from January 2026 directly names it a candidate for "Best Mini PC 2026" in its price range.

🔵 Lon.TV (Reference blog on mini PCs)

Lon Seidman, one of the most respected reviewers in the mini PC segment, evaluated a KAMRUI with Ryzen and considered it "a solid choice for those looking for a low-cost secondary or main PC," although he warns about the uncertainty in the long-term support of brands of this type.

🟠 Amazon (verified users)

The model often appears with aggressive discounts on Amazon: it has been seen at prices as low as $292 USD with stacked coupons. Verified buyers positively rate its boot speed, quiet operation, and VESA compatibility.

🧪 Technical Tests

Here we detail the benchmarks and documented real-world tests of the AMD Ryzen 3 4300U in this type of system:

📊 Geekbench 6

For reference, an Intel Core i7-12700 scores 2,500 in single-core, so the 4300U falls below the latest generation processors, although it surpasses chips like the Intel N95/N97.

📊 PassMark CPU Mark

The Ryzen 3 4300U scores approximately 7,510 points in PassMark Multi-Thread, putting it on par with an 8th generation Intel Core i5-8300H, a reasonable performance for its 15W power consumption.

🎮 Gaming (documented real-world tests)

• Minecraft / Roblox / CS2 (low settings): ✅ Playable at 60+ fps

• Retro emulation (PS2, GameCube via RetroArch): ✅ Works well

• League of Legends / Valorant: ✅ 60 fps on medium settings

• Hogwarts Legacy / Cyberpunk 2077: ⚠️ Playable only on minimum settings (20-30 fps)

• 4K UHD video streaming: ✅ Seamless

🌡️ Temperature and noise

In office use, the fan operates at low speed and the device is virtually silent. Under sustained gaming or rendering loads, temperatures rise but remain within safe ranges thanks to the efficient thermal design.

⚡ SSD Performance

The included M.2 SSD offers typical sequential read speeds of ~2,000-2,500 MB/s, enough to boot Windows in seconds and load applications instantly.

🏁 Final Conclusion

Who is this mini PC ideal for?

• 👨‍💼 Remote and office workers who need a compact computer with multi-monitor support

• 🎬 Multimedia users who consume 4K on one or three screens

• 🕹️ Retro and casual gamers who play indie titles, emulation, or eSports

• 🏫 Educational environments where space and price are key factors

• 🧑‍💻 Web developers who need a clean and quiet second computer

Is it worth it? Yes, especially if you find it with Amazon's frequent sales. At full list price, it might face stronger competition, but with discounts of 40-50%, it becomes a purchase that's hard to argue with.

🔄 Alternatives to consider:

• BMAX B8 Pro (Ryzen 7 5700U) — More graphics power and more cores

• MINISFORUM UM350 (Ryzen 5 3550H) — Brand with the best support reputation
