Transformer with Flat Wire Winding technology

OCDG series power supplies are equipped with high-efficiency transformers with flat wires. These types of transformers have much less magnetic leakage and occupy much less volume than conventional models at high frequencies. Also, in transformers equipped with flat wires, due to the increase of the skin effect at high frequencies and the tendency of electrons to pass through the outer layers of the wire, the AC resistance will be much lower than the models equipped with round wires. This will reduce heat loss and also increase the energy efficiency of the transformer.

High-efficiency MOSFETs with low-RDS in DC-DC converters

OCDG power supplies owe much of their ultra-high energy efficiency to their high-speed switching MOSFETs, low-RDS, and ultra-low leakage currents in their secondary DC-DC converters. This ultimately results in extremely cool performance and a very long lifespan of this series of green power supplies.

Super high quality Japanese capacitors in the initial part

The 1200 watt and 1350 watt models in the OCDG GREEN series power supplies are equipped with two 820uF (1640uF) capacitors with extremely high quality and, of course, the expensive MXK series made by the Japanese company Rubycon. Among the features of this type of capacitor is the long life of 3000 hours at 105 ° C and very low ESR. Also, this high volume of capacitive capacity in the initial part of the ripple will have a very low output and also a guaranteed Hold-Up Time beyond the standards. Meanwhile, for the power of 1050 watts of the same series and in proportion to its output power, two high-quality 680uF (1360uF) capacitors of the MXH series made by the Japanese company Rubycon have been used.

Cable-less Design circuit design

In none of the power transmission sections on the OCDG GREEN series power supply board, no wire is used and the current transfer from the input of the main board to the output of the board related to the cable connections is considered only by the copper lines of the printed circuit board. So that even the board of the Cable Management section of OCDG power supplies is connected directly to the mainboard and its soldering operation is performed. This not only minimizes mass production errors, but in practice reduces energy losses, does not disturb the air circulation inside the power supply, and also increases the purity and quality of the output voltages.

Modern Half-Bridge topology with LLC Resonant converter in the initial section

In this series, thanks to the modern and highly efficient Half-Bridge topology along with the LLC Resonant converter, which softens the switching wave shape (Soft Switching) and the practical implementation of Zero Voltage Switching at the input, EMI, RF carriers, and switching losses at the input are reduced. Findings and energy efficiency (Efficiency) increase significantly. Also, the Resonant Tank Converter (LLC Resonant) allows the switching speed of the input MOSFETs to be much higher than the previous generation topologies, which in practice, especially in the case of idleness, increases energy consumption (efficiency).

Fully modular cabling management system with HCS + connectors with gold plating and 150% more current throughput

All-flat cables and the ability to manage all-modular cabling This series of power supplies will play a decisive role in the faster, more elegant and professional assembly of your system. While in new generation platforms due to the introduction of processors with more cores as well as more power consumption (TDP), motherboard manufacturers, especially in high-end and expensive models, use power connectors in the motherboard class called HCS + (High Current System) server. . These connectors have an average of up to 150% more power to pass current. The new OCDG series power supplies use gold-plated HCS + samples in both the male and female sections in the modular connectors section. In this type of connectors, they increase the operational level and use a much more resistant alloy against high currents in reducing ripple, voltage drop and connection point, and in general, they will increase the stability of the system in overclocking and gaming applications.

Completely modern and efficient cooling system with the ability to select fanless mode

The second-generation OCDG power supplies are equipped with high-quality fans and in industrial application classes with FDB technology. FDB fans, which are currently one of the most modern bearing systems, have an even longer life and, of course, much less acoustic noise than Double Ball Bearing fans. OCDG power supplies also have a digital point controller sensitive to both points inside the power supply and the amount at the power output. This fully intelligent circuit controls and manages the fanless status (at an output load of less than 25% of rated power) and the fan rotation speed in different conditions by analyzing the lines mentioned by the digital microcontroller. In addition, a special switch built into the back of the power can be activated or deactivated by Fanless mode.

5. If Power fails to turn on the system in compliance with any of the above, please contact GREEN after-sales service.

For this purpose, from the top menu of the website, click on the "Calculator" section. Then, select the technical specifications of your parts. Finally, this system introduces the appropriate power supply compatible with your system.

Complete testing of switching power supplies requires specialized equipment and trained personnel. Using the following trick, you can ensure the initial health of your power supply:

- First disconnect all power connectors from the system and power supply. Then connect the desired power to the power wall outlet and turn on the power switch on the back of the power. Next, connect the green wire (pin number 15) and one of the black wires (pin number 16) to the 24-pin power connector using a wire. If the power fan turns on, your power supply is apparently in "OK" status.

- For 12V+ voltage (yellow wires) maximum 5% ± Nominal value: 12.6V+ to 11.4V+

- For voltage 5V+ (red wires) maximum 5% ± Nominal value: 5.25V+ to 4.75V+

- For voltage 3.3V+ (orange wires) maximum 5% ± Nominal value: 3.47V+ to 3.14V+

- For 5VSB+ voltage (paint wire) maximum 5% ± Nominal value: 5.25V + to 4.75V+

- For voltage 12V- (blue wire) maximum 10% ± Nominal value: 10.8V- to 13.2V-

Yes. Thanks to the Active PFC circuit and the protections provided in the input section of the GREEN power supplies, there is no need to worry about connecting this type of UPS to all models of GREEN power supplies.

No. Strictly avoid connecting cables of different models to other models. The arrangement of the pins, the diameter of the wires and the metal alloy of the connectors is unique in different families of GREEN power supplies. Use only the cables inside the power box or the cables approved by the GREEN after-sales service unit.

No. Most PCIe risers on the market carry even more power than the standard for PCIe x16 (about 75W). However, according to ATX standards, SATA and molex connectors have a maximum power transfer of 54W. This means that 21W is applied more to these connectors and this will cause many problems for the user.

The processor power connector (E-ATX) in all green power supplies is of 4 + 4 pin type, which are connected to each other through a special socket. To separate this socket, just pull the socket out from both sides.

This blank pin corresponds to a voltage of -5V. This voltage has been removed in power supplies with ATX12V v2.01 and above. As a result, all modern and new power supplies do not have this pin.
