Antec NeoEco 620C PSU Review

Antec NeoEco 620C PSU Review

Antec NeoEco 620C is an efficient PSU for extreme systems. It fulfills all your requirement and offers constant energy to each component. This psu features an 80 PLUS BRONZE certification which means more efficiency. It is further supported by a 120mm fan. Antec NeoEco also has PFC (power factor correction) that maintains the power output quality with low noise. Even after having a big size fan it does not really produce much sound on extreme usage. Antec in NeoEco series emphasizes more on the safety. The primary feature consists of industrial level protection that prevents short circuit and also protect the system from over voltage. Aim here is to maintain the stable power requirement with reliable output. It is an 80 Plus Bronze certified power unit which offers around 60 to 70% more effective output on any system. 80 Plus simply means the power supply is 80% more efficient compared to the regular one in the market. PFC optimizes the electric power used by removing harmonics. Something that removes the disruption of electrical power. This is most effective in preventing overloading for increased life of all hardware. Below is the short list of features in you which you can see what exactly Antec NeoEco 620C offers. It is loaded with a custom build CircuitShield technology which gives you industrial grade protection on your existing system.

The first one among them is OCP. It is a kind of circuit breaker which stops the supply of extra current which generates heat and increases the risk of fire or damage. Excessive load is properly stopped by adding more life to the components. The second one is OVP which is similar like OCP. It controls excessive voltage spike that appears due to power surge protection from damage. Each hardware in a system is designed to bear an amount of voltage. Excessive voltage can damage them easily. If you have a psu like Antec NeoEco 620C, then you have to worry less. The third one is UVP that maintains the amount of voltage required. Less voltage supply results in poor performance and also hampers hardware circuit. The fourth one is OPP. Sometimes more power is supplied to your system instead of the required power. The extra power can cause shutdown or hardware damage. This feature kicks the excess current and maintains a regular supply. And the last feature is SCP that protects the system components from short circuit. This entire thing is required for any system. Either it is a regular desktop or gaming, you must go with a powerful psu like Antec NeoEco 620C. Spending a bit high amount will help you to save life of your exclusive hardware.

Antec NeoEco 620C comes packed in a simple big size box on which you can see the entire primary feature listed. Also at the bottom right you can see a Guarantee logo that shows up Antec's confidence on this psu. They are sure to give you a high quality product. This is what makes us believe that this product is something value for money. At the front you can see three important features. It is 620Watt psu, 120mm DBB FAN and continues Power. DBB stands for Double Ball Bearing Fan. Regular PSU comes with SBB (Single Ball Bearing) FAN. Compared to DBB, SBB are quieter on high usage. They don’t produce vibration or high sound. Continuous Power means a long and stable output. Antec NeoEco 620C offers consistent power to the system. Every hardware inside the case gets required amount of power. Under Continuous Power of 620W means a constant 620W of power supplied. This psu does not come with any power cable. You can use your existing or buy a new one.


Antec NeoEco 620C is also durable in terms of design. A 120mm fan is placed at the bottom side which maintains the cooling of the circuit. The fan on maximum usage does not produce much sound. It has a thick exterior. Power switch is provided near the power socket. Standard size psu can be used with any system. NeoEco series simply means economical power solution. They are durable and located with industrial grade solution for your desktop pc. This is also ideal for gaming purpose. Connectors are compatible with ATX12V v2.3 & EPS12V v2.91. This psu features universal input that adds compatibility of using it on any kind of ac power source (100- 240v). Here you don’t have to worry about the voltage. The psu has smart features which manages everything. Active PFC (Power Factor Correction) takes care about the required power value. It simply alters the existing current flow and offers stable power transmission. It does not really rely on the power source. The internal circuit is loaded with various technologies that manage everything. In simple words Antec NeoEco 620C is advance power house for your system. Along with power supply it also gives you regulated safety. There are hardly any models in the market which offer you this much features in terms of power supply and power protection as well. This is hard to ignore. Major issue is faced by people when there is short circuit or power failure. It has a Short Circuit Protection feature that manages the excessive current flow. It also does not come with any fuses.

It is an 80 Plus Bronze Certified power supply. It adds 80% more efficiency compared to the regular psu in the market. This type of psu work on optimized power. It does not matter which power source you are using. The psu manages to give only the required current to the system. This adds a great protection from power surge. Today we can see that some high end motherboards come with power surge protection. But they are limited. Through Antec NeoEco 620C your system is protected at source. You do not have to worry about getting your system damaged due to power problem.

It manages the entire current flow smartly.


We had tested the psu on a high end system. I have listed the hardware configuration below and along with this I was also able to find out the maximum power usage of my system on gaming and on overclocking. Antec NeoEco 620C looks more than enough for system that is listed below. Still this system has half amount of power left to utilize. This can be ideal for that system that has dual gpu, a high end processor, front LCD display, more big fans, liquid cooler, etc. The complete power usage of my system is around 360W on ideal and push a bit high when I am playing games. Still I have enough amount of power left to add more things in my pc. I can add an additional gpu, liquid cooler, more hard drive and RAMs. Here you can see any extreme or mid range gaming pc will work really well with Antec NeoEco 620C. The cpu case has dual 200mm fan with led on it. And the entire consumption stays around 368W. Antec NeoEco 620C is ideal for gaming system.

The cost of Antec NeoEco 620C PSU is around Rs.6000. It is a one-time solution. It provides 620W Continuous Power. Continuous means non-stop power. Being a reliable power supply, Antec NeoEco 620C takes care about other power issues. It has industrial grade solutions like Over Current Protection (OCP), Over Voltage Protection (OVP), Under Voltage Protection (UVP), Over Power Protection (OPP) and Short Circuit Protection (SCP). Antec emphasizes more on their product quality and technology. They don't give non-sense product which is high in features but when it comes to usage, they fell short. This is proved through Antec NeoEco 620C and many other quality product sold by Antec. It is worth to buy the PSU as it not only gives continuous power, but also protects the hardware from getting damaged through electric current fluctuation. 80 Plus Bronze Certified adds more efficiency. Smart Thermal Manager makes it the coolest power supply. But it lacks detachable cables. This is provided in many high end psu. This helps people to use only required cable. This also leaves more space inside the CPU case. If we ignore these features than Antec NeoEco 620C is a heavy duty solution for any system at reasonable price.
