It's time to take a zoom Look at the PCB and the circuit design. As the computer is composed of multiple sophisticated circuits, it needs one to guarantee the uninterrupted availability of different stable voltages, that is, + 5V, -5V, + 12V, -12V, 3.3V, etc. in the respective terminals of a power supply. In addition to taking stable voltages into account, the current requirements also change with the operating time: they are driven by the load connected in the output stage of the power supply. But the consideration of the parameters not only ends in the requirements of voltage and current, but extends to characteristics such as the harmonic factor, cross-charge regulation, noise resistance and other safety parameters, including OVP surge protection and protection against OCP overcurrents, etc. to ensure optimization and
Antec's V500PC 500W offers a low-cost, entry-level power supply in a decent budget. It is equipped with an active power factor correction circuit, energy supervisor, EMI suppression techniques and complies with IEC standards. The active power factor circuit (APFC) installed in its input rectification stage is used to ensure the prevention of noise overlap in the AC input network. The attached image shows a supply without a box, extracted from its transparent shock-resistant case. The fan was placed separately after disconnecting it from a soldered JST type connector on the main PCB board. The following paragraphs contain the introduction of its main components that, when played in harmony, provide an efficient, stable and continuous power.
A yellow capacitor with X classification can be seen, soldered through the active and neutral AC cables for the filtering of Electromagnetic Interference (EMI). Shortening of what will cause the fuse to blow, is also nearby. Similarly, capacitors with 02 Y rating are connected through ground and active / neutral wires for the same purpose. Later, the circuit for transient EMI / EMC filtering. It contains 02 common mode inductors, 01 metal oxide varistor (MOV), 01 yellow color, nominal capacitor X and 02 blue capacitors, Y rating.
After the EMI filtering circuit, it is the turn of the active power factor correction circuit (APFC) controlled by the combined controller PWM / PFC IC CM6805. The APFC circuit contains MOSFETS IPA60R125CP, included ferrite coil and IC CM6805. After this, a large capacitor with a 270uF rating is connected for the DC filtration. It is manufactured by CapXon, which is not the top capacitor of the line; however, it has a rating of 400 V and can operate up to 85 C. It can be seen to the left behind the large heat sink that holds MOSFET PFC on its other side.
Then comes the turn for the introduction of all the subsystems that play their respective roles in conjunction with each one. other. The complete design of the power supply from the input stage to the rectification and output filtration stage is shown in the following image.
In addition, towards the secondary side of the main ferrite core transformer, it performs the rectification function together with the filtering for the smoothness of the DC outputs. Since this transformer represents the voltage of multiple stages, so to maintain a stable voltage of any of the output levels in response to the variation in the load, it becomes a defining criterion to qualify the power supply. Here comes the role feedback control, which is guaranteed by returning the scaled output voltage to the PWM IC controller. As stated above, the multiple voltage levels, p. 3.3 V, 5V, 12 V, -12V are sprouting in colored wires labeled PCB to power the respective loads.
The back of the PCB is sufficiently protected with a welding mask. In the same way, the variation in the width of the trace reflects the requirement that the current of different magnitude has been taken into account. Apparently, welding has been done very well with brilliant joints without exception.
As of now, V500PC 500W is enough to satisfy the need of the middle machine, because it provides all the basic components, which are expected from a typical SMPS. The active power factor correction feature is an additional contrast to the fact that the same availability was not used in the supplies in this table.
Since we do not have the right equipment to measure the performance of the PSU, particularly its waveforms to determine the true performance potential, we used Thermaltake Dr. Power II to test the sample unit.
Thermaltake Dr. Power II has the functionality to test the ATX 20 + 4 pin, CPU 4 + 4 Pin, PCIe 6 or 8 pin, SATA and peripheral connectors and report the corresponding voltages by placing a load on the power supply. It also has the ability to report problems with the power supply.
The reported voltages should be compared with the Intel standard and the measurement range of the test equipment. The table below has the Intel Standard, Measuring Range and Voltages reported:
All tested voltages are within the Intel standard. Here are the reported voltages of the connectors:
|Connector||Tested Voltage (V)|
|CPU 4 + 4 Pin + 12V||+12.3  ] PCIe 6/8 Pin + 12V||+12.1|
|SATA||+5.1, +3.3, +12.3|
The Antec VP500PC It is an entry-level budget power source. It is an ecological food source, as it complies with the ERP Lot 6 certification. That and CE would allow this unit to save more energy and put less burden on your utility bill. The unit has a dimension of 150 mm (L) x 140 mm (W) x86 mm (H).

There are no bells. There are no whistles. Without foolishnesses. Obtain power strictly with Antec VP500PC.
The model not of the unit is VP500PC. This is a non-modular PSU, so all cables are pre-installed and leave the PSU as the standard non-modular PSU. The unit follows the Intel form factor of ATX 12V V 2.3. The AC input is 230Vac. The input frequency range is 47 – 63 Hz. The efficiency is 82% at typical load. MTBF is ≥ 100,000 hours. The unit has basic protection characteristics of OVP / OPP / OTP / SCP.
The connectors included in the packaging box are 1x 20 + 4 pin connector on the motherboard, 1x 4 + 4 pin CPU connector, 2x 6 + 2 pin PCIe connectors, 4x SATA connectors, 3x 4-pin peripheral connectors, 1x 4-pin FDD cable that is part of the power cable of the Molex connectors. The PSU has double rails of + 12V with 24A in rail 1 and 21A in rail 2, which makes the total output on the rails of + 12V is 408 W.
The differentiating factor of this PSU is the provision of the correction circuit of the active power factor. This power supply has a price of PKR 5499 / – at the time of the revision. This price and the provision of the Active Power Factor Correction circuit make this power source ideal for basic budget or entry level compilations and for office use. Antec offers 2 years warranty on this unit.
Without timbres, without whistles, without nonsense is the slogan of Antec with its VP500PC and they are fulfilling this aspect, although the lack of Japanese capacitors is a great disadvantage. Against this slogan again, in this price range, one can not complain much. This unit uses capacitors manufactured by CapXon with a nominal voltage of 400 V and can withstand temperatures up to 85 ° C.
