The Ultimate Guide to Buying A Mini PC

N100 Mini PC for office use

Speaking of computer host types that are small in size and easy to carry, in addition to laptops, there is the protagonist of this article PC. There is currently no certain standard for “mini size”, but it usually refers to a computer stick that is less than 5L in size, and there are also computer sticks that are only slightly larger than a pen drive. Mini computers are compact in appearance but have the same functions and performance as Traditional desktop computers. Compared with notebook products, they have the added advantage of being able to freely choose a screen. They are quite suitable for users with limited space and who prefer large screens. Therefore, they have become the first choice for enterprises and individuals to choose a computer for office work in recent years.


However, what configuration should be equipped in such a cramped body, and what should we pay attention to when purchasing? How can I buy a mini PC that is satisfactory to use? This must be a big problem for consumers who are new to this type of product. Therefore, this article will introduce the purchasing guide in terms of CPU specifications, performance cores, heat dissipation, etc., and recommend JIERUICC’s best-selling office mini-computer models for your reference and choice!


  1. Mini PC purchasing guide

Before getting into product recommendations, let’s take a look at what you need to pay attention to when purchasing!


Choose the appropriate configuration according to your needs


Mini computer


In terms of usage, computers can be roughly divided into Light office work (mainly web browsing and OFFICE software applications, writing emails, etc.), Gaming, Video editing, Drawing & design, etc. The required mini-computer configurations are different. In addition, a Mini PC with better configurations is also more expensive, so you should first determine the main purpose and then look for a machine with matching configurations. This way, it will not be difficult to find a mini PC that is satisfactory to use and fits your budget.


intel CPU

1>CPU processor


CPU specifications will directly affect the operating performance of the system, and will also determine the operating range of the computer. Due to limitations in size and cooling performance, most mini computers often use laptop-level Intel Core i3 to i5 low-voltage versions of CPUs; computer sticks use lower-end Celeron processors or Atom processors. series, its performance can only be used for Lightweight tasks such as browsing web pages and MS Office applications.


However, with the advancement of technology, now also have mini-computers specially designed for gaming or drawing & design. Their processors can reach Intel Core i7 to i9, which can smoothly edit videos or play games. Therefore, if you want your computer to be used for a wider range of purposes, it is recommended that you at least choose a mini-computer with a processor level above Intel Core i5 or AMD Ryzen R5.


The number of CPU cores represents its multi-tasking capability. The more cores there are, it is like having more people dividing the work, allowing multiple data operations to be performed at the same time. Taking the Intel Core series as an example, from the i3 dual-core to the 11th generation i7 and i9 eight-core, the more cores there are, the stronger the multi-tasking performance will be. For general daily office use, quad-core is more than enough, but if you have drawing and design needs, it is recommended to choose six-core or 8-core to make the operation smoother.


In addition to core count, clock speed is another important performance indicator. The clock represents the computing cycle of the processor (the common unit is GHz). The higher the value, the faster the computing speed. Even if it is the same 11th-generation i7 eight-core CPU, there will be a performance difference of 1.4GHz to 3.6GHz depending on the product classification. This information will be marked on the mini PC specification sheet. As long as you have a good grasp of these key figures when choosing, you will be fine. You can select a CPU with suitable performance.


2>Choose the appropriate RAM/SSD capacity


RAM:SSD capacity


Memory plays a vital role in the speed of use of minicomputers. It is like a high-speed driving lane. If it is a single lane, the speed and number of passing vehicles will be greatly reduced. If it is a two-lane or With multiple lanes, the number and speed of vehicles it can pass will be greatly increased. In addition, the memory speeds of DDR3L, DDR4, and DDR5 are different. The higher the frequency of memory, the faster it runs. Of course, the type of memory is determined by the mini computer’s CPU and motherboard. DDR5 memory can only be used for Intel 12th or above CPUs, and cannot be used for Celeron’s low-end CPUs.


The type and capacity of the hard drive will also affect the reading speed of the mini-computer. Common hard drive types are Msata, SATA (2.5inch), and the latest M.2 SSD, with capacities ranging from 16GB to 2TB. The more advanced the hard drive type, the faster the reading speed. but the price is also the most expensive. For example, M.2 SSD is the most expensive. Consumers can choose the appropriate hard drive type and capacity according to their own needs to maximize cost performance.


If it is used for daily lightweight office work, choose 8GB of memory and 256GB of hard disk.  For video editing, 4K or 8K video playback, etc., you need to choose RAM 16 or 32GB, SSD 512GB-1TB.


3>Independent graphics cards bring the best user experience


Discrete graphics card


The display chip is a small processor responsible for executing graphics functions. It mainly displays the system’s operation results on the screen. It can be divided into two categories: integrated graphics cards and independent graphics cards. Common integrated graphic cards such as Intel UHD Iris Xe series and AMD Vega 8, while the display chips on independent graphics cards are mainly from NVIDIA and AMD.


Although the processing performance of core graphics has improved rapidly recently, if you need to play AAA games, 3D graphics, or high-end creations, you still need a separate graphics card to have sufficient computing performance. However, high-end graphics cards often come with their cooling fans for cooling purposes, so they cannot be installed in particularly small hosts. Models that require independent graphics cards, such as gaming or graphics, can only be reduced to a “relatively mini” size. Generally, performance and mini PC size need to be considered when purchasing.



  1. Pay attention to the heat dissipation design


Radiator built into the chassis


To save space, some minicomputers adopt a fanless design and are equipped with low-heat components. The benefit is that they can operate in complete silence. However, without active cooling, the effectiveness of the passive cooling design in dissipating heat is crucial.  Common passive cooling methods include adding heat sinks, adopting an aluminum alloy design for the chassis, and increasing the number of ventilation holes to help heat air escape as quickly as possible, but these methods can only meet the needs of low-heat operations.


If you want to perform complex computing tasks, it is still recommended to choose a mini PC with a cooling fan installed inside or in the chassis to ensure stable operation of the system. Generally, when purchasing, you should comprehensively consider various aspects such as the heat generation status of the internal components, the heat dissipation design, and whether a fan can be installed.


  1. The I/O Ports of Mini PC



Whether for work or leisure and entertainment, many people now use dual screens or three screens to increase work efficiency. Whether a mini-computer can provide multi-screen output mainly depends on the display chip or independent graphics card specifications. These can be confirmed in the product specification sheet to understand the supported output types and number of monitors. For example, some models provide Dual HDMI output, and there are also mDP plus HDMI configurations. Those who like high-definition displays need to further confirm whether they support 4K image transmission.

In addition to screen output, if it can also have other commonly used I/O interfaces, such as USB, RJ45, Type-c, etc., it will increase the convenience of use. Generally speaking, larger sizes can provide more types and numbers of connectors. If compactness is the most important consideration, some I/O interface types may be sacrificed and adapters or expansion kits may be used instead. The method can be supplemented, and this part can be chosen according to personal needs.
