Frequently Asked Questions
Why is the power supply unit important for gaming?
Having a power supply unit is crucial for gaming setup because it supplies consistent and stable power to all the components in your rig. This, in turn, can protect your system from power surges, fluctuations, and outages, ensuring the longevity of the gaming components. Always consider investing in a good quality, decent PSU that gives your CPU and RAM the power to function optimally.
How do I determine the right wattage for my gaming PSU?
The right wattage entirely depends on the power requirements of your computer. In case you have a setup that has a relatively high-end CPU or GPU, then it’s definitely going to end up consuming more power. Calculate the total power consumption of all the components and then add a 20-30 percent buffer so the PSU is not running at maximum capacity all the time.
How does the fan size and type in a PSU affect my gaming experience?
Due to the massive and constant flow of power supply to the components, your unit has a high chance of getting overheated. This is where the cooling system comes in. Size-wise, a larger fan can cool the rig more effectively at a lower RPM, which ensures that there is minimal noise during operation. Some of the higher-end models also feature zero RPM modes, where the fin only basically spins under heavy loads.
