Why I Believe a 850 Watt Computer Power Supply is Necessary
As a computer enthusiast and someone who builds their own PCs, I have come to understand the importance of a reliable and powerful power supply. A 850 watt power supply may seem excessive to some, but in my experience, it is necessary for several reasons.

By having an 850 watt power supply, I can easily swap out old components for newer ones without worrying about compatibility issues or insufficient power.
Another reason why I believe a 850 watt computer power supply is necessary is for stability and reliability. A high-quality 850 watt PSU can handle heavy loads without straining or overheating, which ultimately prolongs the lifespan of my computer. It also provides a stable flow of electricity to all components, reducing the risk of any sudden shutdowns or malfunctions.

My Buying Guide on ‘850 Watt Computer Power Supply’
When it comes to building or upgrading a computer, one of the most important components to consider is the power supply. This is because it is responsible for providing stable and reliable power to all the other components in your system.

In this buying guide, I will share with you all the necessary information you need to know when looking for an 850 watt computer power supply.
What is an 850 watt computer power supply?
An 850 watt computer power supply is a device that converts AC power from your wall outlet into DC power that your computer’s components can use. It provides enough power to ensure that all your components are running smoothly and can handle high-performance tasks such as gaming, video editing, and graphic design.
Why do I need an 850 watt computer power supply?
If you are planning on building or upgrading a high-performance computer, then an 850 watt power supply is essential. It provides enough headroom for future upgrades and ensures that your system runs smoothly without any issues. Additionally, it allows you to connect multiple graphics cards for gaming or other intensive tasks.
Things to consider before buying an 850 watt computer power supply
- Wattage: As the name suggests, an 850 watt power supply can provide up to 850 watts of power to your system. However, it is essential to note that this number may vary depending on the efficiency of the unit. It is always recommended to choose a higher wattage than what your system requires for future upgrades.
- Certifications: Look for certifications such as 80 Plus which indicate the efficiency of the power supply. The higher the certification level (Bronze, Silver, Gold, Platinum), the more energy-efficient and reliable the unit will be.
- Cables: Make sure to check if the power supply comes with enough cables and connectors for all your components. Modular or semi-modular units allow you to only use the cables you need, resulting in better cable management inside your case.
- Fan size: A larger fan size (120mm or above) means better cooling and quieter operation compared to smaller fans.
- Budget: While it may be tempting to go for a cheaper option, investing in a quality and reliable brand will save you from potential damage caused by cheaply made units.
