Super value for money

The pivotal feature of the ECO series power supplies is their outstanding performance-to-price ratio. In fact, this series is aimed at those users who, even with a limited budget, intending to buy a standard power supply with a valid warranty and after-sales service.

Maximum Energy Efficiency of 86%

Having quality parts and materials along with Forwarding-topology and the process of manufacturing plus fully automatic quality control together has increased the efficiency of this series up to a maximum of 86% beyond the 80PLUS's Standard for this series. This has reduced energy consumption losses, reduced heat-output, and resulted in a completely silent performance.

Active PFC power factor correction

Despite the numerous nonlinear elements in switching power supplies, the need to install power factor correction (PFC) systems, in addition to reducing energy consumption losses, also reduces the user's power consumption costs. Thanks to the APFC circuit used in the input section of the ECO series power supplies, the power factor will be about 0.9 or more at a load of more than 20%.

Including ErP Standard 2013 For This Series

Switching power supplies always consume a small amount of power as long as they are connected to the city power supply due to the 5V Standby circuit, even when they are off. In power supplies equipped with a standby circuit with controlled and modern consumption, this rate is much lower. ECO series power supplies have less than 0.4W consumption in this situation, which is unique in this price range.

More accurate performance of safety protections

The Supervisor chip is the most important part of all switching power supplies in modern PSUs. The ECO series 450W / 500W models use a much more modern and accurate Supervisor chip than the previous generation models, and the customizations made in its unit, in practice, provide a much narrower and more precise range for controlling OCP and OPP protections.

105°C Durable Capacitors Made by SamXon

Quality capacitors always play a decisive role in increasing the life and voltage stability of the output rails. The 450W / 500W ECO Rev3.1 Green series power supplies are equipped with high-quality 105°C capacitors in the input and output section, made by the well-known company SamXon. These capacitors have a much longer life than similar models due to the modern manufacturing process and first-class materials used.

Stable performance even in 40°C environment

Optimized design and quality materials and components have made the ECO GREEN series power supplies, even at ambient temperatures of 40°C, have the ability to provide their rated power in a completely stable and guaranteed way.

Hold-Up Time at least 12ms in 100% load

Receiving from a quality input capacitor (Bulk) with suitable capacity in ECO powerheads causes the hold-up time interruption time (Hold-Up Time) to be approximately 12ms even at maximum output power. This interruption tolerance ensures the guaranteed performance of this series in unstable power conditions of the city and also provides compatibility of slow-acting UPSs with ECO series power supplies.

Two-stage EMI filter in the input section

Thanks to the two-stage and complete filtering in the input section of the ECO series power supplies, the EMI / RFI carriers created by the MOSFETs and switches in the input section will not penetrate the city's power transmission and distribution network under any circumstances. Also, thanks to the two components NTC Thermistor and MOV (Metal Oxide Varistor) installed in this section, the ECO series power supplies are insured against primary inrush currents and severe voltage spikes in the city.

Ultra-quiet thanks to the smart fan controller

Thanks to the ultra-intelligent fan controller for the new generation of ECO power supplies, the sound noise of these models is very low up to 70% of the rated capacity of the power supply, and in this range, practically no sound from the power fan will reach the user.

Black, full-flat output cables

In the 450W / 500W ECO series models, all output cables are of flat type with full-black color. Flat cables are more flexible than conventional types, which makes parts cabling easier and makes the system assembly more beautiful.

• Any change in the specifications of the device and its opening by unauthorized persons will invalidate the warranty.

• Due to the rapid growth and development of computer parts, in the absence of the original model of the device, alternative models are offered, taking into account the price difference of the time being.

• Defective power supply to sales agents or warranty service office for replacement (according to warranty conditions), repair, or complete technical testing is the responsibility of the buyer.

1. Please make sure that the power cord is properly connected and that the power button on the back of the power supply is on.

2. Please ensure the correct and complete connection of all cables as well as the correct direction of the connectors to your system.

3. Make sure there is no short circuit in the system. To do this, remove one of the system components from the circuit each time and try again.

4. If any of the above happens to you, unplug the power supply for 2 minutes and turn it off. Then reconnect the power supply.

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.

In this video, the reasons and solutions to solve this problem are fully explained:

- If you live in Tehran, send your defective device with all accessories and boxes to GREEN after-sales service unit at the following address:
No.215, Between Gharani Ave & Nejatollahi St, Somayeh St

- If you live in Iran but not in Tehran, find the nearest after-sales service Agents to your place of residence on the "Agents" page and deliver the defective device to the desired representative.
