In the selection of installed DIY players, the power supply in the system is often the easiest to determine. The selection is completed by calculating the corresponding power, selecting the corresponding brand and price. In this context, how to control the cost, add more selling points to the power supply and enhance the quality of workmanship is undoubtedly the biggest problem.
Of course, the leading Hua Dan of Kuleng is the current high-end V gold medal series, while the mainstream market is the GM bronze medal series launched this year, which is targeted at the middle and low end, that is, designed by a large group of entry-level players. GM series has four options, namely 450/550/650/750/750, according to different wattage ratios. Today, we will show you G650M.
In terms of packaging design, the main color of the low-end GM series is black and white, and the design style is neat and simple, showing the corresponding selling points and rendering. Among them, the selling points of GM series are semi module design, 80PLUS bronze certification, back-end DC-DC design, 12V single output and five-year super long warranty.
On the back is the introduction of the corresponding module line and the corresponding circuit protection measures. The back also has the corresponding fan voltage and speed relationship. It can also be seen from the back that under the input conditions of 110V and 230V, the conversion efficiency curves of G650M under different liability states have reached the 80PLUS copper standard.
There is corresponding protection on the internal packaging.
G650M power supply body and module line family photo. In terms of module cables, the G650M is equipped with two 3 * SATA power supply module cables, one 3 * large 4PIN power cable and one 1 * small 4PIN power cable.
The G650M is a half module design, with one 8PIN interface CPU power supply line, one 24PIN mainboard power supply line, and one 2 * 6 (+2) PIN graphics card power supply line. All the wires are wrapped with snakeskin mesh, which is of moderate length and convenient for wiring.
View details from various angles. As a power supply, for most players, whether the power is sufficient for the use of the platform is actually the most critical and important indicator, and it is likely to stay in this indicator. In addition to providing different power for consumers to choose from, the GM series has also passed the 80PLUS bronze certification, which can save power charges for players and improve conversion efficiency, all of which depend on its internal materials and structure.
The G650M uses a fan that supports temperature controlled speed, and the manufacturer is YL.
Details of each part of G650M's internal disassembly. G650M adopts active PFC+double transistor forward+DC rectifier output structure internally, which is a very mature and stable scheme and has obvious effect on stabilizing the output voltage. The architecture of back-end DC-DC provides a good foundation for its conversion efficiency, which is also a highlight. There are also two EMI circuits inside, and the filter design is excellent.
The GM series is positioned at the middle and low end. With the 80PLUS bronze medal and a variety of power options, it can well satisfy and attract entry-level players to choose, not to mention the excellent and upright internal workmanship under the brand of Cool Cool. Due to its low positioning compared with the V series, the GM series is not too rich and eye-catching in packaging design and accessories, but it is durable and enough. Isn't it what entry-level players value?
