Ever since Intel updated the ATX power supply specification, the vast majority of power supply brands have kept up, launching power supplies that adhere to the ATX3.x specification. Due to the small probability of burning out the 12VHPWR graphics card connector with power supplies following the ATX3.0 specification, major power supply brands have introduced power supplies based on the improved ATX3.1 specification, with traditional power supply giants being particularly proactive. For instance, the well-known power supply brand Super Flower has released several ATX3.1 power supplies, such as the LEADEX III 1000W power supply we have previously experienced, as well as the ZILLION FG1050W power supply discussed in this article.

Different Power Outputs

Standards Vary

In the eyes of many DIY enthusiasts, Super Flower is a well-known brand in the power supply industry. Its series such as Leadex, Ice Mountain Golden Butterfly, and LEADEX are all classic works in the industry. However, compared to these classic series, the ZILLION series from Super Flower may still seem a bit mysterious. In fact, the ZILLION series is not entirely new; it has been used in Super Flower's case product line before. For example, the M705 case previously launched by Super Flower was the first product in the ZILLION series.

The Super Flower ZILLION FG series offers four models with different power outputs to choose from: 650W, 750W, 850W, and 1050W. It is important to note that the 650W and 750W models adhere to the Intel ATX2.53 specification, which is more suitable for mid-range platforms. The 850W and 1050W power output models are based on the Intel ATX3.1 specification, and consumers are advised to choose based on their own needs when purchasing.

Smart Temperature-Controlled Fan Speed

Ensures Quietness and Cooling in Low-Load States

The Super Flower ZILLION FG1050W is an ATX specification power supply, but its body is relatively shorter compared to other ATX specification power supplies, with dimensions of 140mm (length) × 150mm (width) × 86mm (height). The Super Flower ZILLION FG1050W features an "ZETA" 120mm FDB bearing fan with a copper sleeve design, which can enhance its service life. The model number is "ZFF122512H", and it is the same brand of fan used in the Super Flower LEADEX III 1000W, Antec PlatiGemini 1200W, and Antec REVOLUTION D.F.12. This fan has 9 fan blades, and compared to a 7-blade fan, a 9-blade fan performs better in terms of silence. Typically, increasing the number of blades can reduce the noise generated when a single blade comes into contact with the air because a multi-blade design can smoothly distribute air pressure, reducing air turbulence and vibration. Therefore, a 9-blade fan operates more quietly than a 7-blade fan.Additionally, whether it is a 7-blade or 9-blade design, this odd-numbered blade configuration effectively reduces the uneven distribution of centrifugal force, making the fan operate more smoothly, reducing noise and vibration, and increasing its service life. Moreover, this fan also incorporates a copper bushing, which serves to lower the temperature of the copper shaft and enhance the lifespan of the fan. At the same time, the fan supports intelligent temperature control, which can adjust the fan speed according to the load, thereby maintaining a balance between cooling and noise.

Furthermore, the power supply features an ECO smart temperature control design, with an ECO switch located next to the power supply switch. When the switch is in the "ON" (enabled) position, the fan will not operate when the power supply is under low load, and it will only start operating when the internal temperature of the power supply reaches around 60°C, effectively reducing the noise generated by the fan during low-load operation. When the ECO switch is in the "OFF" (disabled) position, the fan will start operating immediately after the power supply is activated, and it will automatically control the fan speed according to the changes in the internal temperature of the power supply. At low load, the fan operates at a low speed, and at high load, it operates at a high speed.

The ZILLION FG1050W from ZOLLE also adopts the classic windmill heat dissipation structure, with ventilation holes designed on both the fan side and the power switch interface side. At the same time, its holes feature a specially designed pattern, which is more aesthetically pleasing than many simple round or honeycomb holes.

Single +12V output

1050W 80PLUS Gold Certification

From the nameplate of the power supply, we can learn some information about the ZILLION FG1050W: it supports a wide range of input voltages from 100V to 240V and 200V to 240V, with an input current of 7.5A to 14.8A (7.5A domestically). It uses the same single +12V output as mainstream power supplies, capable of outputting a maximum of 87.5A current, with a combined output of 83.4A current, which translates to an output of 1050W of electrical power. The power supply's +3.3V and +5V can output 20A of current respectively, with a combined output of 100W of electrical power. In addition, its -12V can output 0.3A of current, and +5VSB can output 2.5A of current, outputting 3.6W and 12.5W of electrical power respectively. It is worth mentioning that since this power supply is sold in multiple countries and regions worldwide, it has also undergone a variety of domestic and international safety certifications, such as China 3C, UK UKCA, EU CE, and German Rheinland.

The upper right corner of the power supply's nameplate also prominently displays the 80PLUS Gold certification logo, which means that the ZILLION FG1050W has a high power supply conversion efficiency: under 115V input, it needs to achieve a conversion efficiency of not less than 87% at 20% load, not less than 90% at 50% load, and not less than 87% at 100% load. The ZILLION FG1050W, under 115V input, has efficiency ratings of 89.47%, 91.88%, and 89.75% at 20%, 50%, and 100% loads respectively, with a conversion efficiency that is close to the 80PLUS Platinum standard, and a comprehensive conversion efficiency of 90.37%, which is very high. Additionally, the positioning of this power supply is lower than the LEADEX series, and there will be differences in the warranty period. The ZILLION FG1050W offers a 5-year warranty. The specific warranty policy is: free replacement within 1 year, and free repair for the following 4 years.  We tested the various input voltages of the Zolin ZILLION FG1050W using professional equipment. Through testing, its -12V voltage is 11.9V,+12V1 and+12V2 are all 12.1V,+5V is 4.9V, 5VSB voltage is 5.1V,+3.3V voltage is 3.2V, and all voltage values are within the normal range. Full module design Adopting dual 8Pin to 12V-2x6 interfaces As a power supply positioned at the mid to high end, the Zolin ZILLION FG1050W naturally comes standard with a full module design. It is equipped with 12 sets of interfaces, including 6 sets of processor powered and PCIe powered interfaces, which can share module interfaces. In addition, it also provides 4 sets of SATA/PERIF (Big 4Pin) interfaces and 2 sets of motherboard interfaces. Observant readers may find that this power supply is not equipped with the 12V-2x6 interface of the ATX3.1 power supply? This is because it uses a dual 8pin adapter with 12V-2x6 interfaces. In addition, since the 650W and 750W of the Zolin ZILLION FG series are ATX2.53 specifications, they use ordinary wires.   The cables equipped with the Zolin ZILLION FG1050W are all flat type, which is very common. Many power supplies we have previously evaluated use this type of cable, which not only facilitates user wiring, but also makes the interior of the chassis more beautiful. The power supply includes 1 20+4-pin main power supply (600mm), 2 processors (4+4-pin) power supply (700mm+150mm), 1 dual 8pin to 12V-2x6 graphics card power supply (700mm), 3 6+2pin PCIe graphics cards power supply (700mm), 2 SATA power supply (500mm+150mm+150mm+150mm), 2 large 4pin+small 4pin power supply (500mm+150mm+150mm+150mm), and 1 Molex to FDD cable (100mm). As can be seen, the power cables are relatively complete, and the length can also meet the needs of ATX and even E-ATX chassis for back wiring.   Mainstream circuit design Materials used for capacitors across TaiwanAs a mid-to-high-end ATX 3.1 power supply, what are the internal materials and circuit design of the ZILLION FG1050W from Zhuoling? How does it differ from the LEADEX series? After disassembling it, we can see the detailed internal situation: it adopts an active PFC combined with LLC half-bridge resonant technology, supplemented by a 12V synchronous rectification scheme. This technical solution has long been widely recognized in the field of power supply design, and it is favored by mainstream power supply brands for its high efficiency and stable performance.

The layout of components inside the power supply is compact and orderly. It has a complete EMI filtering circuit. For example, its primary EMI filtering circuit is at the AC input end, and it is equipped with two separate PCB sub-boards. The outermost thin blank sub-board mainly serves as an insulating isolation, which is relatively rare among peer products. Most peer products use direct wire connections to save more costs. Theoretically, Zhuoling ZILLION FG1050W could also be designed this way, but it still adds more materials. Perhaps this is the difference of a big factory, not cutting corners where consumers cannot see.

On the PCB sub-board, there are 2 X capacitors and 1 Y capacitor for primary EMI filtering. The X and Y safety capacitors usually added to the primary EMI circuit of a power supply can not only effectively suppress common-mode and differential-mode interference, improving the stability and signal quality of the circuit, but also enhance the safety of the equipment, meeting the requirements of electromagnetic compatibility. Below the primary EMI filtering circuit, on the main PCB, is the secondary EMI filtering circuit of the power supply. It is equipped with 2 common-mode inductors and 2 Y capacitors, which can not only capture and cancel common-mode interference signals but also further play a filtering role, suppressing common-mode currents and eliminating higher harmonics.

Next to the common-mode inductor is the primary rectification circuit of the power supply. It uses 2 GBU25M bridge rectifiers. The specification of such rectifiers is usually 1000V/25A, and their average rectification current reaches 25A, with a working temperature range of -40°C to 150°C. If calculated at the lowest voltage of 100V, the rectification power can reach 2500W. Even with an efficiency of 80%, there is still 2000W of rectification power, which is still significantly higher than the rated power of the power supply. If the rectification bridge's power is lower than the rated power of the power supply, it indicates that the power supply is falsely marked with its rated power. The 2 rectifiers equipped with Zhuoling ZILLION FG1050W are fixed back-to-back on an independent heat dissipation module to ensure heat dissipation effect.

The main PCB is equipped with 1 semi-solid capacitor from CapXon (Fengbin) HP series from Taiwan, China. The quality is comparable to well-known first-line capacitor brands such as Japanese Rubycon and Nichicon, and the cost is not low. According to the official website, the specific model of this capacitor is "HP821M420P550A". The specification of this main capacitor is 420V/820μF, with 0.78μF per watt (under normal circumstances, the capacitance value of the main capacitor should not be lower than 0.5μF per watt), which shows that its materials are quite solid. This capacitor can withstand a temperature range of -25°C to 105°C and has a service life of up to 5000 hours.

The main capacitor must have two key functions: first, it must ensure the voltage regulation capability of the rear-end system, which is to maintain the stability of the system operation; second, it also needs to have sufficient energy storage capability to meet the hold-up time requirements under full load output as specified in the Intel ATX 3.1 specification. The hold-up time mentioned here specifically refers to the period after the AC input power is cut off, during which the +5V output voltage can continue to be stable until it drops to 4.75V (i.e., below 5% of the standard value). This period is crucial for protecting sensitive equipment such as mechanical hard drives, ensuring the safety of data and the integrity of equipment during power outages.There is a small piece of PCB board nestled between the main capacitor and the primary side rectifier circuit, with external insulation material wrapped around it. This is the power supply's PFC board, on which we can see a main control chip is mounted, but due to the narrow gap, the specific model cannot be seen. Next to the main capacitor, there is a large heatsink module connected to another end of the PCB sub-board. Three PFC switching tubes are installed between the sub-board and the heatsink module, but the silk-screen model numbers are completely obscured, making it impossible to see the specific models. Next to the 5V transformer of the power supply, there are also three "EL817 C411" optocoupler chips, which serve functions such as electrical isolation, anti-interference, circuit protection, feedback sampling voltage, and control of the switching tube duty cycle. This allows the power supply to operate stably and output stable and smooth direct current, ultimately meeting the electrical needs of the equipment.

On the other side of the main capacitor is the power supply's main transformer. To the left of the transformer, there are two boost diodes with the model number "SRC60R068BS", which come from Shenzhen Sanrise and are individually isolated. On the other side of the main transformer is the power supply's filtering circuit, equipped with 5 CapXon solid-state capacitors (2200μF/16V, 100μF/16V), 3 CapXon electrolytic capacitors (3300μF/16V), and a ferrite ring inductor for filtering, with a metal plate for isolation.

Between the filtering circuit and the transformer is the power supply's 12V synchronous rectifier tube, which uses a total of 8 "014N04SA" (40V/200A/1.45mΩ) from InPower Semiconductor (CRRC Semiconductor, IPS), with 4 rectifier tubes and 4 freewheeling diodes. Additionally, there is a DC to DC section next to it, responsible for converting +5V and +3.3V voltages. Its fan start-stop control is not integrated into the DC to DC sub-board but is connected to the main PCB for control. Of course, there are many other components that we will not introduce one by one here.

It can be seen that although the ZILLION FG1050W from Super Flower has a slight gap in material selection compared to the LEADEX series, it still maintains a high standard in all aspects of circuit design, with all the necessary components. Its parts are also from well-known suppliers in the industry, providing excellent electrical performance for the power supply.

In conclusion, the Super Flower ZILLION FG1050W, as a kilowatt-class ATX 3.1 power supply, can easily meet the power supply needs of mid-to-high-end hardware platforms, especially in terms of precision and stability. Although its positioning is slightly lower than the LEADEX series, the disassembly shows that it maintains a high standard in internal materials and circuit design. Especially in places that users cannot see, it uses more solid components than its peers, such as an independent PCB at the AC input end, a greater number of PFC switching tubes, and rectifier bridges capable of carrying higher power, all of which ensure the long-term and stable operation of the power supply.
