KAMRUI GK3Plus Mini PC Review – Mini Desktop Computer

Introduction

The KAMRUI GK3Plus Mini PC is a compact, affordable micro desktop solution aimed at home, business, and digital signage applications. At roughly 5.1 × 5.1 × 1.96 inches, it nearly disappears behind a monitor yet packs a 12th Gen Intel Alder Lake‑N95 processor, 16 GB of DDR4 memory, and a 512 GB M.2 SSD—features typically found in larger, more expensive systems. Launched in late 2023, its low 15 W TDP design promotes energy efficiency without sacrificing everyday performance, positioning it between entry‑level Celeron/Pentium devices and pricier Core‑series mini PCs. With VESA mounting, triple‑display 4K support, and Windows 11 Pro pre‑installed, the GK3Plus appeals to users seeking a plug‑and‑play small form factor solution for tasks ranging from office productivity to light multimedia and casual gaming.

Unboxing & First Impressions

Out of the box, the GK3Plus arrives in a plain cardboard sleeve containing the mini PC, a 65 W power adapter, HDMI cable, VESA mounting kit, and quick‑start guide. The barebones documentation offers little beyond port orientation and mounting instructions, but Windows 11 Pro comes pre‑activated, saving setup time and licensing hassles. Physically, the aluminum‑topped chassis and plastic sides feel sturdy, though The Register noted some flex under pressure on the chrome vents—suggesting average build quality consistent with its budget price. The inclusion of an HDMI cable and mounting hardware adds value, enabling immediate deployment as a fixed‑install digital signage or HTPC without extra purchases.

Design & Build Quality

Aesthetically, the GK3Plus opts for stealth: a matte‑black finish with subtle ventilation grilles atop and on the sides keeps the look professional for both office desks and living‑room setups. At 0.86 kg, it’s light enough to mount on the back of a monitor yet solid enough not to feel toy‑like; however, bend tests reveal slight give in the plastic chassis, particularly around the vent cutouts, that may concern durability‑minded buyers. Rubber feet on the bottom prevent slipping and raise the device for airflow, while the VESA bracket clips securely into place, transforming any VESA‑compatible display into an all‑in‑one PC in seconds.

Internal Layout & Upgradeability

Accessing the interior requires removing four screws and sliding off the bottom panel, revealing a single SO‑DIMM slot (populated with 16 GB DDR4‑2666), an M.2 2280 slot housing the 512 GB SSD, and a 2.5″ SATA bay. This spring‑loaded design makes upgrades painless: users can expand RAM to 32 GB or add up to a 2 TB 2.5″ drive without dismantling the entire chassis. The single‑slot cooling solution and compact PCB layout reflect thoughtful engineering for serviceability in a minimal footprint.

Memory & Storage

The pre‑installed 16 GB DDR4‑2666 module delivers smooth multitasking—allowing 15–20 browser tabs alongside Office suites and light photo editing without stutter. The 512 GB M.2 SSD offers sequential read/write speeds around 1,800/1,200 MB/s in CrystalDiskMark tests, slashing boot times to under 12 seconds and application launches to near‑instant. The internal SATA bay’s support for up to 2 TB 2.5″ drives provides ample room for media libraries, while the NVMe slot’s PCIe 3.0 bandwidth ensures future SSD upgrades will remain cost‑effective.

Connectivity & Expansion

On the rear panel, two HDMI 2.0 ports support dual 4K 60 Hz displays, while the VGA port accommodates legacy monitors—an unusual but welcome inclusion for enterprise rollouts. USB connectivity spans four USB 3.2 Gen 1 ports (two front, two rear) and two USB 2.0 ports for peripherals, alongside a 3.5 mm audio jack and mic‑in for headsets. Gigabit Ethernet offers wired reliability, with Wi‑Fi 5 and Bluetooth 4.2 covering wireless needs; an upgrade to Wi‑Fi 6 would be preferable, but the current radio handles typical streaming and conferencing tasks without noticeable lag.

Display & Multimedia

The GK3Plus drives up to three simultaneous displays—two via HDMI plus VGA—each capable of 4K 60 Hz output, making it ideal for digital signage or multi‑monitor productivity setups. Video playback benchmarks show smooth hardware‑accelerated decoding of 4K HEVC and VP9 streams in VLC and Edge, with CPU usage under 25%. Intel’s Quick Sync support accelerates light video transcoding tasks, reducing a 5‑minute 1080p clip’s export time in HandBrake to roughly 90 seconds.

Networking Performance

Through a 1 Gbps Ethernet link, transfers between NAS devices peak at 115 MB/s, saturating the wired connection. Over Wi‑Fi 5 (802.11ac), real‑world throughput averages 350 Mbps at 10 meters from the router, sufficient for 4K streaming and video calls. Bluetooth 4.2 handles keyboards, mice, and headsets with no dropouts, though devices supporting BT 5.x would enjoy slightly lower latency and extended range.

Thermal Design & Acoustics

Under idle, core temperatures rest at a cool 40–45 °C with fan speeds around 800 RPM, generating a whisper‑quiet 22 dBA. Light browsing and office work see fan speeds up to 1,200 RPM (around 28 dBA), still unobtrusive for co‑working spaces. Stress testing with Prime95 and FurMark pushes E‑cores to 85 °C, ramping the fan to 1,800 RPM and 35 dBA—noticeable but manageable; pointing an external desk fan at the intake reduces peak temps by 8 °C and tames noise to ~30 dBA. Thermal throttling occurs only after sustained heavy loads, unlikely in typical usage scenarios.

Software & Driver Support

KAMRUI ships the GK3Plus with Windows 11 Pro, tailored drivers, and a recovery image accessible via USB on request. Out‑of‑the‑box Wi‑Fi, Ethernet, audio, and GPU drivers install automatically via Windows Update, ensuring seamless plug‑and‑play functionality. While unofficial Linux compatibility exists, users report manual driver solutions for Wi‑Fi and graphics may be required—acceptable for enthusiasts but a hurdle for enterprise Linux deployments.

Real‑World Productivity

In everyday office workloads—Word, Excel with large spreadsheets, multiple Chrome tabs (20+), and Zoom calls—the GK3Plus remains responsive, rarely exceeding 50% CPU load. Cold‑boot to desktop completes in 12 seconds, and resume from standby takes under 3 seconds. PDF rendering, email clients, and remote desktop sessions perform on par with entry‑level laptops, making it a viable thin‑client, POS, or digital signage controller.

Media & HTPC Use

Media enthusiasts will appreciate the triple 4K output for multi‑room setups, smooth 4K Netflix and YouTube playback, and Dolby Digital decoding over HDMI. Plex server transcodes a single 1080p stream without dropping frames, though 4K transcoding strains the N95’s modest GPU. The compact form factor and VESA mount make it an excellent living‑room HTPC, circumventing bulky receivers or streaming boxes when paired with a USB‑C to HDMI audio extractor.

Casual Gaming & Emulation

While modern games are beyond its scope, the Intel UHD Graphics Xe can handle light eSports or retro games. Rocket League at 720p on low settings averages ~35 fps, though dips occur in intense scenes . Emulators for NES, SNES, or PlayStation 1 run flawlessly, and lightweight indie titles (e.g., Stardew Valley, Undertale) maintain 60 fps at 1080p. For users seeking a compact retro‑gaming cabinet, the GK3Plus is a cost‑effective foundation, though a discrete GPU or N100 variant may yield higher frame rates in older 3D titles.

Comparisons & Alternatives

Compared to N100‑based rivals (e.g., Beelink SER5, MALLRACE GK3 Plus), the N95’s higher TDP sustains turbo clocks longer, delivering ~15% better multi‑threaded throughput at the cost of slightly higher thermals . Fanless mini PCs like the MINIX Z100 run silently but sacrifice 20–25% CPU performance and lack upgradeability . For heavier workloads or entry‑level gaming, Ryzen 7 Pro or Core i3-N305 systems start around $350, offering double the multi‑core performance and superior iGPU capabilities, albeit in a larger chassis .

Price & Value

Retailing at $200 on Amazon to date, the GK3Plus outperforms similarly priced N100 8 GB models and undercuts $350+ fanless alternatives on raw CPU benchmarks. Frequent sales can drop prices below $200, delivering exceptional value for small‑office deployments, schools, or media setups. The bundle—Windows 11 Pro, 16 GB RAM, 512 GB SSD, VESA mount, HDMI cable—removes ancillary costs, positioning the GK3Plus as one of the most cost‑effective, upgradeable mini PCs on the market.
