Buying Guide to Choose the Right Power Supply (PSU) for Gaming

A power supply’s specifications and durability must be checked in detail before you place your order. Though the budget is an important criterion, consider not to pick a power supply just because it is cheaper. A power supply should qualify under industrial standards to prove its efficiency. Especially for gaming, you need powerful equipment that can withstand heavy loads and work consistently without lags. An inferior quality power supply will not only produce lower performance but also will destroy your gaming PC or system.  

1. Wattage

The wattage of a power supply is one of the topmost factors you should look at. It will measure the power supply’s performance. Since we are looking for a power supply for gamers, the power output should not be less than 500 W. Prefer power supply with a DC output above 700 W. For hardcore gamers, a power supply with 900 – 1000 or more Watts will deliver excellent high-end performance. To handle medium loads, a power supply with 700-850 W will suffice. Along with the wattage, you should also look at the efficiency of the power supply. Higher the efficiency of the power supply, the higher the performance. High-efficiency models will also reduce your power consumption, thus saving your money. 

2. Efficiency certification

Every power supply will have an efficiency certification such as 80 plus bronze, 80 plus platinum, 80 plus titanium, 80 plus gold, 80 plus silver, etc. These are labels to measure the efficiency of the power supply. It will determine its performance when connected to a system. If you don’t find a proper certification label on a power supply, you should skip to purchase it. This certification will also ascertain the reliability and performance of the equipment. Also, make sure if the power supply supports all ATX systems.

3. Design

Design in power supply doesn’t just refer to the external design. The power supply comes in versatile designs: With fan / Without fan, Fully modular / Semi-modular design. You can choose the design according to your gaming needs. The fan-less design is suitable for quiet and silent environments. Many power supply models offer fans included a design with smart technology. This technology will produce minimal noise during heavy loads and can work in silence for medium and low loads. They also help in heat dissipation and cool down the working system. The fully modular design will make sure there is no clutter. It will make installation easier in the CPU. You will not require unnecessary cables to be connected in a fully modular design. The semi-modular design will reduce clutter and not completely clutter-free.   

4. Safety and protection

Safety and protection are some of the important aspects to be noted when buying a power supply. Power supply equipment with improper or not fully developed safety standards tends to explode or work intermittently. They will not only affect the gaming performance but might ruin your gaming PC / system. The components and parts of the power supply must be tested and ensured under reliable safety norms. You can look for safety and protection standards such as Over Voltage Protection (UVP), Under Voltage Protection (UVP), Over Current Protection (OCP), Over Power Protection (OPP), Short Circuit Protection (SCP), and Over Temperature Protection (OTP) in the power supply manual. After all, it is merely an electrical device and you can’t take risks with lower standard items.

5. Durability

The durability of the power supply is also an important factor to be considered. Make sure the power supply is constructed with premium quality components and parts. It must qualify the industry and professional standards. Important parts such as the circuits, regulators, capacitors, etc. should be manufactured by trustworthy manufacturers. Some of the power supply models come with Japanese capacitors. These are good industry standards and can be considered reliable. Keep in mind, a power supply you buy should last for many years and not wear off so quickly. A power supply with less durability will wear off soon and also spoil your computer function. 

6. Warranty

Warranty is the practical factor to be noted. Since you are placing your money on the power supply to function for many years, you should also know that not every product is completely long-lasting. Technical and functional issues are very common in electrical items. A warranty card is like a trusted ticket the brand offers. You can always go back to the manufacturer when you face any component failure or functional failure in your power supply. The warranty period will allow you to replace or repair the non-functional component in a limited time. Many models offer a warranty period of up to 5 or 7 years. Some even offer 10 year warranty. You can pick the one you prefer accordingly.  

Frequently Asked Questions (FAQs) About Power Supply (PSU) for Gaming in 2021

1. What is the ideal power supply range for gaming?

Most of the gaming PCs can run with a power supply around 500-600 W. You cannot go lower than 400 W range. For more efficient and hardcore gaming, you can go higher up to 850- 1000 W. The GPUs should be of top quality and in coordination with the power supply to enable high performance.

The GSU and PSU are directly dependent on each other to give a balanced output. When one goes down, it will pull the other with it, ruining your gaming.

4. What is the function of a fully modular power supply?

A fully modular power supply will ensure there are fewer cables involved in your power supply connection. It will drastically reduce clutter and enable proper airflow. Apart from looking neat, this will make it easy for you to install the equipment in your computer CPU. It will also reduce the overall heat produced in the supply.  

5. Why is fan-less power supply design a better option when compared to the power supply with fans?

Power supply with a fan-less design will allow you to work peacefully with no noise generated. It will be best suitable for environments that are quiet or silent.
