When you can own a standard power even with minimal cost

Great value for the price

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

Maximum energy consumption efficiency is 88%

Having high-quality parts and materials along with the Forward topology and the fully automatic manufacturing and quality control process has increased the efficiency of this series up to a maximum of 88% beyond the 80PLUS Standard for this series. This has reduced energy consumption losses, heat reduction and the result of completely silent operation of this series.

Active PFC power factor correction

With the presence of many non-linear 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 electricity costs. Thanks to the APFC circuit used in the input part of the ECO series power supplies, the power factor will be about 0.9 and even more at a load of more than 20%.

ERP standard 2013

As long as they are connected to the city electricity, switching power supplies always consume a small amount of electricity even when they are turned off due to the existence of the 5V Standby+ circuit. In power supplies equipped with a standby circuit with controlled and modern consumption, this amount is much lower. ECO series power supplies in this condition consume less than 0.3W, which is unique in its kind in this price range.

Full protection like high-end models!

550/600W models of ECO series power supplies have all the safety protections (OVP, UVP, OCP, OPP, SCP, OTP, NLO, SIP) just like the high-end models to protect your health and the valuable parts of your system even in The worst possible conditions are guaranteed. Also, the optimizations made on the supervisor chip of these models have made the performance of these protections more accurate and faster than similar models.

Durable 105C capacitors made by SamXon company

A high-quality capacitor always plays a decisive role in increasing the life and voltage stability of the output branches. 450W/500/550/600W ECO Rev3.1 Green series models are equipped with high-quality 105C capacitors made by the well-known SamXon company in the input and output sections. These capacitors have a much longer life than similar samples due to the modern manufacturing process and the first grade material used.

Solid capacitors (Solid) type 105C in the output section

The most sensitive capacitors of the secondary part of the 550/600W ECO series models have been selected from Solid and 105C. Solid capacitors perform much better at high frequencies than conventional types of electrolyte, show lower equivalent series resistance (ESR), and their stability at high temperature is significantly higher.

Stable performance even at ambient temperature of 40C

Optimized design and high-quality materials and parts have made ECO Green series power supplies able to provide their rated power in a completely stable and guaranteed way, even at an ambient temperature of 40 degrees Celsius.

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

Having a high-quality input capacitor (Bulk) with a suitable capacity in the head of the ECO power supply has caused the hold-up time to be around 12ms even at the maximum output power. This amount of interruption tolerance has ensured the guaranteed performance of this series in unstable city electricity conditions and has provided the compatibility of slow-performing UPSs with ECO series power supplies.

Equipped with a two-layer EMI filter in the input section

Thanks to the two-layer 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, due to the two pieces of NTC Thermistor and MOV (Metal Oxide Varistor) embedded in this section, the ECO series power supplies are insured against inrush currents and severe city voltage spikes.

Extremely quiet thanks to the smart fan controller

Thanks to the super smart fan controller intended for the new generation ECO power supplies, the sound noise of these models is very low up to about 70% of the rated power, and practically no sound from the power fan will reach the user's ears in this range.

Black and completely flat output cables

In 450W/500/550/600W models of ECO series, all the output cables are of flat type with black color throughout. Flat cables are more flexible than common types, and this makes the cabling of parts easier and makes the system assembly more beautiful.

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.
