In order to attract the attention of consumers, some power supplies have written product features on the outer packaging of the power supply, such as conversion efficiency, full voltage, the length of the power supply wire and the number of interfaces, etc., which can catch consumers' attention.
One: Five characteristics of good power supply
The power supply in the computer host is an accessory that consumers may ignore. In fact, real DIY players will never choose a power supply product casually. The power supply is comparable to the engine of a car. The quality of the engine determines the performance of the car. In fact, the power supply in the computer is the same. A good power supply can make the platform have good performance. The biggest headache for entry-level players. In fact, choosing a good power supply is not a headache. Power products are nothing more than fixed information. As long as you have this knowledge, you can easily choose.
At this time, many players will ask what is the information to choose the fixed power supply? Players who understand the power supply will first choose products that match the rated power of their platform, and secondly, look at the brand. This is the first thing to determine when the package is not opened. After opening the package, it is necessary to understand through the nameplate of the power supply Good understanding of performance, in addition to nameplate players also have to choose the type of wire. Compared with netizens, how to choose how to choose must be a bit overwhelming. Let's talk about how to choose one by one.
Two: learn to understand the power supply packaging
Power packaging is the first thing players see, whether it is the most intuitive and important for consumers to know the specific product information through packaging. For entry-level players, he has no knowledge of power supplies and the brand recognition is not comprehensive, so power packaging is the way these consumers can best understand the product. A good power supply package must have the manufacturer name, product model, product features, etc.
Basic parameters are indispensable
The manufacturer's name, model, and specifications on the power supply package are indispensable. These can provide consumers with basic parameters. These parameters can be used to know whether they can meet their own needs when purchasing the power supply. Experienced manufacturers will display product information as much as possible, so that consumers can better understand the product.
Featured display is essential
In order to attract the attention of consumers, some power supplies have written product features on the outer packaging of the power supply, such as conversion efficiency, full voltage, the length of the power supply wire and the number of interfaces, etc., which can catch consumers' attention. The conversion efficiency is often the highest value of 80PLUS certification or efficiency. The full voltage proves that the power supply can be used in any environment. The power cord can let consumers know whether they can meet their platform and wiring requirements.
Three: one nameplate output certification can not be less
After opening the package, the power supply nameplate that can best convey the information to consumers is the power supply nameplate. A standardized power supply nameplate allows consumers to know a lot of information. Whether the nameplate is clear or not can also reflect whether a manufacturer is frank. We know that some manufacturers' products are very simple in the design of the nameplate, and even the minimum power rating is omitted. How can such products allow consumers to buy with peace of mind?
Detailed index only + 12V is the most important
In addition to the rated power, it is a detailed indicator of each output: + 12V, + 5V, + 3.3V, -12V and + 5VSB output for standby. Because large power consumers such as CPUs, graphics cards, and even cooling fans need to use + 12V for power supply, + 12V is an important indicator for judging the actual load capacity of the power supply. Generally, the output power of + 12V accounts for 80% of the total power to meet the current needs. If it has multiple outputs and accounts for more than 88%, it means that the power supply has a strong output and can handle higher-power graphics cards than the same-rated power supply.
