As work-from-home setups, home media centers, and compact entertainment PCs become more popular, mini PCs have emerged as an appealing solution for users who need desktop-class performance in a pint-sized package. The KAMRUI GK3 Mini PC packs a quad-core Intel Jasper Lake processor, ample memory and storage, and a full complement of ports—yet fits in the palm of your hand. In this article, we’ll explore its design and components, dive into real-world performance, weigh up whether it’s worth your investment, outline key pros and cons, and help you decide if this mini marvel belongs on your desk or behind your TV.
Product Overview
Compact, Sturdy Design
The GK3 measures just 5.0 × 5.0 × 1.9 inches and weighs under one pound, making it one of the smallest full-featured PCs on the market. Its aluminum-alloy shell not only sheds heat efficiently but also feels solid and premium. On its underside are VESA-mount holes, so you can attach it discreetly to the back of a monitor or a TV—turning any screen into a fully capable Windows workstation or media hub.
Core Hardware
-
Processor: Intel Celeron N5105 (quad-core, 2.0 GHz base, up to 2.9 GHz burst)
-
Graphics: Intel UHD Graphics (Jasper Lake), capable of 4K video playback
-
Memory: 8 GB DDR4 (soldered; single-channel)
-
Storage: 256 GB NVMe M.2 SSD (expandable via second M.2 slot)
This combination delivers smooth performance for everyday tasks—web browsing, office productivity, video conferencing, and even light photo editing—while the integrated GPU handles 4K streaming and casual gaming at lower settings.
Connectivity and Expansion
Despite its miniature footprint, the GK3 doesn’t skimp on ports:
-
Display Outputs: 1 × HDMI 2.0, 1 × DisplayPort 1.4 (via USB-C)
-
USB: 2 × USB-A 3.0, 2 × USB-A 2.0, 1 × USB-C (data and DP)
-
Networking: Gigabit Ethernet, Wi-Fi 6 (802.11ax), Bluetooth 5.2
-
Audio: 3.5 mm headphone/microphone jack
-
Storage Expansion: Secondary M.2 slot and a 2.5″ drive bay (SATA) hidden under the chassis
A rear-facing power button and front-facing LEDs complete the user-friendly layout, making plug-and-play setup a breeze.
Operating System and Software
The KAMRUI GK3 ships with Windows 11 Home preinstalled, giving you the latest security and feature updates out of the box. With Windows 11’s desktop enhancements—snap layouts, virtual desktops, and integrated Teams—you’ll feel at home whether you’re in “office” mode or kicking back for a Netflix marathon.
Performance in Everyday Use
Productivity and Multitasking
The quad-core N5105 handles standard office suites effortlessly. In tests:
-
Document Editing & Spreadsheets: No lag toggling between multiple Word and Excel documents.
-
Web Browsing: Smooth scrolling with 10–15 Chrome tabs open, including video-heavy sites.
-
Video Conferencing: Zoom and Teams calls at 1080p run without dropped frames or audio stutters.
With 8 GB of RAM, most users will find the GK3 responsive when switching among applications, though power users who keep dozens of tabs open may want to upgrade memory (where supported) or turn to 16 GB variants.
Media Playback and Light Gaming
-
4K Video: Native 4K at 60 Hz output via HDMI or DisplayPort, with hardware-accelerated H.264/H.265 decoding.
-
Streaming: Netflix, YouTube, and Prime Video all play flawlessly in high definition.
-
Casual Gaming: Older or less demanding titles (e.g., Minecraft, Stardew Valley, or Rocket League at low settings) run smoothly, though AAA gaming is beyond its integrated GPU’s scope.
Boot and Load Times
Thanks to the NVMe SSD, cold boot to desktop takes around 12–15 seconds, and applications like Office and Spotify launch virtually instantly—mirroring the snappy feel of larger, more expensive laptops.
Buying Opinion: Is the KAMRUI GK3 Right for You?
Who Will Benefit
-
Home Office Workers: Gain desktop reliability in a tiny footprint. Mount it behind a monitor for a clutter-free workspace.
-
Media Enthusiasts: Turn any TV into a streaming powerhouse or light-duty Plex server with 4K output and Wi-Fi 6.
-
Educational Settings: Deploy in classrooms or libraries where space and budget are both at a premium.
-
Tech Hobbyists: Expand storage, install Linux, or add a second drive—this mini PC invites tinkering.
Considerations Before Buying
-
Memory Limitations: 8 GB is adequate for most, but power users may find it constraining; check if a 16 GB model or aftermarket upgrade is available.
-
Thermal Constraints: Under sustained heavy load (e.g., prolonged video encoding), the small fan can become audible and temperatures will rise—consider occasional breaks in intensive workflows.
-
Port Placement: With many ports on the rear, cable management behind a monitor can be tight; plan your desk layout accordingly.
Overall, if your computing needs center around productivity, media, and light multitasking—and you crave minimal desk clutter—the GK3 delivers strong value in a micro-sized package.
