Description

The Beelink J45 mini PC has a design that reminds us of the Intel NUC models, in the bright top we have the brand logo. On the front we have a status LED on the rubber ignition button, two USB 3.0 ports and audio jack. In the side microSD reader and in the back we have the other connectors where stands out the double HDMI 1.4 port that allows us to connect two monitors at once.

  • Materials: Plastic and aluminium.
  • Interfaces: 4x USB 3.0  / 2x HDMI 1.4 / microSD / Jack audio in-out / Kensington lock.
  • Accessories: DC 12V 2A adapter/ 2x HDMI Cable / SATA Support / Manual.

In the lower area we find four rubber feet with the fixing screws of the lid, if we open it we can see the SATA connector to mount a 2.5″ disk, in the lower area we only have the copper-cooler fan in contact with the CPU and RAM soldered on the board, this mini PC has the option to hang it on a VESA support included and we also have two HDMI cables, one short and one long.

  • Expansions: 1x mSATA (128GB in review) / 1x miniPCIe for opcional Wifi/ 1x SATA 2,5″

START UP

System and user experience

We turn on the Beelink J45 by pressing the front button of the box, as indicated by the specifications we have Windows 10 Pro 64bit correctly activated. We check the list of devices and note that all have their drivers installed correctly, the systems work without problem.

  • OS Version installed: Windows 10 Pro 64bit.
  • Software pre-installed: None.

The Windows 10 Pro system moves correctly, thanks to the 8GB of RAM we can do a lot of loading of navigation tabs without loss of performance, if we buy the 4GB RAM model, of course we can not do so much content loading. A perfectly valid computer for office suites, multimedia and classic apps.

Support, BIOS and other OS

The Beelink has its own website and contact email. We can access the BIOS by pressing ESC, it has a classic AMI BIOS with many special options, a product that allows us to set on with the internal clock, we recommend not to touch the BIOS a lot because we can leave the system frozen.

  • BIOS: Classic AMI BIOS in text mode.
  • Power management: Wake on Lan.

This model is fully compatible with Ubuntu, we can check it from a USB boot drive, all the devices are detected and we can use the hardware without problems. LibreELEC is also compatible.

HARDWARE TEST

Storage, RAM and Ports

We passed mSATA disk speed tests installed by default, we also tested the 8GB of RAM that comes by default in Dual Channel configuration, we also check the speed and functionality of its ports.

  • USB ports: Four USB 3.0

We check the speed of the integrated SATA SSD disk and it gives us some pretty good performance figures within that category, we do not have the option of expansion with another type of internal storage.

We have installed a module of 8 GB of RAM DDR4L in Dual Channel format, the analysis programs indicate that they work at 2133MHz and the results are normal for this kind of hardware.

Electric consumption, temperature and noise

If we check the consumption on the Beelink J45 we can see performance of the Intel Celeron J4205 processor with 10W TDP it has low figures as usual in these models and we can see that we remain at a contained level even in the highest performance scenarios.

We perform our thermal and acoustic tests on the Beelink J45 Mini PC, as we have verified the ventilation system works fine and is not noisy, the internal fan works always at minimum revolutions and if we are close there is a continuous sound. If we run a game to some powerful application if that is more audible but not annoying.

  • Measuring temperature: 25ºC
  • Noise: Min. rpm = 25 db / Max. rpm  = 40 db

In our review we make several types of tests to check the performance in each use scenario, with this data we can make an idea of the overall real performance that the system will have during its working life.

  • Continuous extreme performance: 63ºC Max. / CPU 1.7 GHz / NO thermal throlling and NO limited CPU
  • Overclock: Available but we do not recommend touching the BIOS.
  • Performance in games: LOL 54ºC / CPU 1.8 GHz average and 2.7 GHz máx.
  • External temperature: 30ºC on the surface.

Wifi, Ethernet and Bluetooth

Integrated in the mini PC Beelink J45 has installed a wireless adapter Wifi 3165D AC de Dual Band with Bluetooth with which we connect to an ASUS RT-AC1200G+ Router, a mid-range device. We perform tests on the use of streaming using the iPerf measurement tool to see the maximum performance of each network adapter.

  • Wifi speed results: Correct speeds for this network adapters.
  • Scope Wifi: At a distance of 5 meters with a wall we have a signal of 43 dBm, a very poor result.
  • Bluetooth: Works correctly and connects without problems
  • We recommend reading our Tutorial SAMBA on Android networks if we are going to use files from our network PC

PERFORMANCE TEST

Processor

Inside the Beelink J45 mini PCwe found integrated an Intel Celeron J4205 processor with four cores and four threads that moves between 1.5 and 2.6 GHz and an Intel HD Graphics 505 GPU up to 800 MHz with 18 EU. This chip has a maximum consumption of 10W TDP, the results are correct within an Apollo Lake processor, as we see it is at the level of more modern models with similar consumption. A correct processor to navigate, multimedia playback with KODI or use of office suites at user level, we can also run design apps at medium level.

Benchmarks

Games

In our benchmark withgames on the Beelink J45 we can see the results, the values are classic in line with this type of product of this type, the Intel HD Graphics GPU 505 is perfectly valid for simple games such as we can find in Android phones by downloading them from the Microsoft Store. Also indie titles in 2D or current games with light 3D load like LOL, the emulators are also feasible but at the most we stayed in some simple Wii titles.

  • GTA V / Overwath / Fortnite, low settings, 720p resolution and no VSync.
  • LOL / CS:GO, ow settings, 1080p  resolution and no VSync.
    *On models with powerful discrete GPU settings in medium and 1080p resolution

With the Beelink J45 we have performed a performance test with the game League of legends (LOL) which is quite light and we can play at 50fps, DOTA 2 is more demanding and we usually have 10fps less. We also do a special test with CS:GO and we see that we stay at 24fps in 1080p, only if we lower the resolution to 720p we can play minimally at 31fps but it is not recommended.

VIDEO AND AUDIO TESTS

Video playback test

In the video playback aspect the Beelink J45 mini PC with the integrated Intel HD Graphics 505 have a VPU with hardware support for the HEVC codec and for basic VP9, in this processor we have support for 10bit color video and also HDR although we can reproduce it in basic color quality since Gemini Lake does not have HDR with native support. This mini PC is perfectly valid as a multimedia system to use KODI or PLEX.

Audio playback test

We past test with the Beelink J45 using a Yamaha RXV-577 AV receiver checking that the miniPC supports DD and DTS 7.1 pass through, is curious because the default hardware only supports stereo and does not have licenses for DD or DTS formats. We recommend, as always, to update all the drivers with Windows Update to the latest before connecting the device to our AV receiver.

    * Our AV receiver does not support these native formats but we verify that it is played back to 7.1

Streaming services

For the streaming aspect in the Beelink J45 mini PC we check the most popular streaming services such as Youtube, Netflix, HBO, Amazon Prime Video and others with their native apps or using the most compatible browser. You can consult our guides where we explain in detail all the best known streaming services, how to configure them and what requirements are necessary to see content in HD or 4K quality

Opinion

As we have seen the Beelink J45 is a very complete model in NUC format, it stands out for its compact size and the possibility of expansion in its internal storage. A small computer that can be valid for a desktop use, browse intensively or run basic design applications. This model has variants with 4GB or 8GB of RAM soldered in plate and allows us to mount  another  2.5″ disk unit inside the case, without a doubt very flexible despite its size.

The mini PC Beelink J45 has an internal fan that keeps temperatures low, don’t have semi-passive fan system but it is quite silent. At network usage level, the Wifi aC adapter behaves normally, we have a Gigabit Ethernet adapter and the BIOS of the system is quite complete, it is also compatible with other OS. This mini PC have several USB ports and dual HDMI output to connect two monitors simultaneously.

The model Beelink J45 as we see a compact and interesting computer, a good model of mini PC for desktop use or multimedia playback.
