Recently, one of the computers in the home will have a sudden noise when they are turned on. It is estimated that the power supply is not working, so I plan to replace it. I was originally planning to replace the ATX power supply directly, but I thought that if the small machine installed not long ago, the space would be much more, and I could add a few hard disks. ATX gave the old machine the original price RTX30 card to be upgraded, killing two birds with one stone. So I found the SFX small power supply of Jinma Diamond 650M, which is less than 1 yuan per watt. The power supply accessories can be used for many years, and it is too cheap to use. Other brands are very expensive. The Golden Diamond 650M power supply is less than 1 yuan per watt. It has a gold medal conversion efficiency of 80Plus, and can be replaced in 5 years. It is still relatively cost-effective.
First Ma, Golden Diamond 650M SFX Power Supply Unboxing
▼ First Ma, Golden Diamond 650M SFX Power Supply is also much smaller in packaging than ATX Power Supply, which is almost the same as the size of two ordinary motherboard packaging boxes. The main color of the gold Diamond 650M package has a black main color, and the power rendering and model on the front. The biggest feature is printed on the right: 80PLUS Gold Certification and SFX full module.
▼The back is a 24K gold diamond power supply, which has several major features of the series, such as 80PLUS gold certification, DC-DC converter, single-channel +12V output design, etc. Usually, better power supplies with 80plus gold medals and above will use DC-DC technology. The power supply characteristics of the DC-DC structure are: +12V maximum output power is approximately equal to the rated power of the power supply, +5V and +3.3V are output through +12V DC voltage buck. The DC-DC structure can achieve more accurate voltage control compared to other methods, so it can achieve good voltage deviation and other performance.
▼The side is the wire specifications of each model of the Gold Diamond Series SFX small power supply series. You can see that the Gold Diamond 650M motherboard power supply interface length is 300MM and the graphics card power supply interface length is 400MM.
▼ After opening it, you can see the small power supply on the left and the accessories wires on the right of the simple storage bag storage.
▼ Take out the accessories, and the motherboard power supply, CPU power supply, graphics card power supply, serial port power supply, large D port and other module lines are available.

▼Looking at the nameplate of the Golden Diamond 650M, you can see that this is a single-channel +12V output 80PLUS gold medal conversion efficiency power supply. The main power consumption of the host is the CPU and graphics card. The +12V that provides power to these two components is the top priority. The Golden Diamond 650M single-channel +12V output, and the maximum current 52A can provide a maximum power of 624W, which can drive most graphics cards below the RTX3070 series. At the same time, there is a gold medal introduction to the full voltage in the lower left corner. In layman's terms, the full voltage is a wide range and can be used at a voltage of 100V-240V, which can reduce downtime in severe weather such as unstable voltage or lightning.
▼Look at the fan, the Golden Diamond 650M is a 92mm size fan, which supports temperature control and silent PWM speed regulation.
▼ In terms of module interface, in addition to the motherboard power supply interface, there are 2 CPU module power supply interfaces, and there are 2 graphics card power supply interfaces, and there are 3 module interfaces for use in SATA interface or large D port.
▼The power supply AC input interface is a relatively common rice cooker interface, which supports wide-format AC input from 100V to 240V. It can ensure the good operation of the computer in places where the voltage is unstable.
▼There are two module power supply lines for the CPU, each with 1 4+4 interface design, and a total of dual 8pin CPU power supply power output.
▼There are also two graphics card power supply module cables, each with dual 6+2pin design and 4 8pin power supply, which can drive most graphics cards below the RTX3070 series. For graphics cards that require multi-interface power supply, the best way to connect is to use only a single interface for a wire, which can reduce the load on the connection terminals at the wire and module connection heads and improve stability.
▼There are also one SATA module power supply cable and one large D-port module cable, each with 4 interfaces.
▼The length of the module line can be referred to as the following size. Including the power supply terminal at the front end, the motherboard module power supply line is about 34cm, and the CPU module line is about the same as the graphics card module line, about 44cm.
First Ma Gold Diamond 650M SFX Power Supply Installation
▼ Start to start the machine, the flat module wire is combined with the SFX small power supply, and the installation is very easy.
▼This machine case is a Maquzhuan I'm. You can install the M-ATX motherboard and ATX power supply, and use the SFX power rack to install and mount it.
▼After the SFX power supply is mounted to the front panel of the chassis, a lot of space is freed up, especially after the two SSD hard disks on the front panel are freed up, it can be convenient to add the hard disk.
▼It has good results without using module customization lines.
▼ Compared with the large ATX power supply at the previous power supply location, the SFX power supply takes up much less space, and you can add an extra fan on the top.
▼The appearance of this host is quite satisfactory, with white and pure colors that make people feel happy.
The power supply is changed. Whether the power supply is good or not still needs time to check, time is the only criterion for quality inspection. The small gold medal full-module SFX small power supply with a compact size and strong performance is not expensive. It has a new warranty in 5 years. Overall, the small gold diamond 650M power supply of Xianma is quite attractive.
Thanks for reading!
