For those who have been familiar with DIY hardware for many years, they will not simply pursue hardware performance. When building a host, they also need to consider various aspects, such as power supply. Stability, heat dissipation, and aesthetics inside and outside the mainframe are mostly related to the chassis power supply. In addition to the visual display of the chassis, the power supply may not be enough attention for everyone, usually only think that the rated power is enough, everything is not good, but its internal materials, thermal design, silent performance and wire layout will bring different experience to DIY users. .
The latest Antec EA500GREEN full-module power supply, users can freely match the output line, making the host wiring more tidy. Passing the Antec 30 years of quality, the internal materials are superior, with a rated 500W foot tile guarantee, plus up to 85% conversion efficiency, reduce internal heating of the power supply, reduce the cost of electricity when the computer is running. In addition, 14CM cooling fan with intelligent temperature control design makes the whole machine more silent.
2 packaging and appearance
The overall appearance of the package appearance of the Antec EA500GREEN power supply is equivalent to the same type in the past, and the mainstream is more traditionally turned up and down. It is black and yellow, and the front product renderings are more cool and domineering.In the lower right corner, there is still a striking "real tile" mark.
The main side of the package is the "full-mode power supply 500W foot tile" words, a word introduced the main selling point of this power supply. In addition, 85% conversion efficiency indicates that the power supply has high performance.
Open the package of the Antec EA500GREEN power supply and you will see the familiar internal protection design.The power supply is wrapped in a fairly thick foam sponge, not afraid of collisions during transit. Thanks to the full module design, the power supply itself is placed in an environmentally-friendly bag, without the bending folding of the main power cord. The module wires are individually wrapped in a carton. In addition, the instructions for use are naturally indispensable.
Before removing the power supply, first see the module interface part, providing SATA*4, main power supply*1, PCI-E*3, cpu*1 output, interface Very well equipped.
All accessories include one set of module cable, power cord*1, cable tie*4 , fixing screws *4, simple and sufficient for users.
A set of modular wires and Antec EA500GREEN
The overall appearance of the Antec EA500GREEN power supply is still the mainstream design of the blackening, and the metal casing is sprayed with a special process. Treatment, the type of matte feel, the delicate but uneven outer layer increases the overall heat dissipation area, making the power supply heat dissipation performance. The left and right sides of the power supply are labeled with Antec logo, 500W power, and EA GREEN full name, at the same time, stickers There is also a convex imprint of "Antec" below, which gives the player a unique personality.
The top surface of the power supply is the product nameplate, rated power is 500W, The +12V output is divided into two parts independently, and +12V1 provides 18A output.+12V2 provides 17A output, +12V totals 35A, there is no problem for medium and high-end graphics card crossfire, and independent output can keep the power supply more stable.
The power fan face is separated by a conventional iron mesh. The special blue "A" in the center and the "Antec design" and "From 1986" are all very special. .
The rear side of the power supply adopts a honeycomb cooling mesh, which mainly has a three-pin power interface and a power independent switch.
3 Conversion efficiency and deviation value Test
Check whether a power supply performance is strong, and naturally there is no shortage of professional equipment testing. Here, our team Antec EA500 GREEN The power supply performs some more professional tests to test some of the invisible data through test instrumentation.
Power Test Platform
We tested the conversion efficiency of Antec EA500 GREEN from 20%, 50%, and 100% load, respectively, and measured the conversion efficiency of the power supply under these load conditions.
Test Product: Antec EA500 GREEN
Input Power (W) Output Power (W) Conversion Efficiency
20% load 123.75101.4982.01%
50% load 296.41252.6785.24%
100% load 601.69503.7683.72%
Power Conversion Efficiency Chart
As can be seen from the above test data, the Antec EA500 GREEN power supply achieves 85.24% high conversion efficiency in 50% typical load.
Test Product: Antec EA500 GREEN
Unit: V+12V+5v -12v+3.3V+5Vsb
20% load 12.215.0712.173.335.06
50 % load 12.145.0312.183.325.05

Maximum deviation from 1.75% 1.40% 1.75% 1.50% 1%
Voltage deviation value
Look at the power deviation test, the voltage offset of each power supply part is very small, these deviation values are controlled quite well, basically reach the hearts of DIY players The standard of the best power supply is also an important reason why DIY players have always liked the Antec power supply.
4 Internal materials
Because you need to ensure the accuracy of the test data, After the test, disassemble it. From the previous test of the Antec EA500 GREEN power supply, the conversion efficiency of this power supply is high, and the internal materials and workmanship are also first-class? Next, go to the dismantling section and see what's going on inside.
Before disassembling the power supply, please explain to the audience. If you have the same power supply, don't just disassemble it. After disassembling, it will give up the warranty. Here, in order to show you the internal materials of the Antec EA500 GREEN, and also believe that this power supply has first-class quality, it is not afraid to be removed!
just unscrew the 4 fixing screws on the fan face.The power can be easily turned on. First look at the power supply PWM temperature control cooling fan, 14025 specifications, that is, the diameter of 14cm, thickness 25cm standard specifications, at the same time, DC 12V 0.18A, large fan specifications plus small current design, the ultimate silent Questioning, the power dissipation effect is even better than that of many power wattages.
The main body of the power supply, you can see that the entire base plate is not too large, the design is biased towards compactness, and the components inside the power supply are arranged more closely together, which is beneficial to improve Transmission efficiency inside the power supply.
Overall, the power supply uses more patch components, making the main components There is plenty of room for heat dissipation. Although the heat sink is not too much, the extension is quite thick, which naturally plays a big role in heat dissipation.
EMI suppresses circuit aspects, consisting of 2 Xcapacitors, 2 common mode chokes, 1 differential mode choke and 2 Y capacitors.
Control Daughter Board
pfc The main capacitor uses a temperature-resistant 85-degree electrolytic capacitor, 330uF/420V, and the capacity is very sufficient.
5 Evaluation Impressions and Summary
In the past, most of the module power supply was only at the high end. The model appeared above. Since last year, the whole module power supply has appeared constantly. In the case of sufficient power, it is very suitable for the use of Volkswagen DIY users. In the power cable combing, it is finally better to control and create an internal wiring. A more beautiful host.
This evaluation of the Antec EA500 GREEN is also a full-module design of the people-friendly power supply, with ample module interface, equipped with a film wire is also good enough, but not using a flat line, slightly regret. But I don’t want to hide it,The cooling fan has a size of 14cm and is equipped with intelligent temperature control, which is absolutely safe for users at least in terms of mute. In addition, the internal components are compact and the materials are used to ensure the long-term stable operation of the power supply. Overall, the performance of all aspects of the Antec EA500 GREEN full-mode power supply is more prominent, and it will be a leader in the same type of products, it is recommended
