Buyer’s Guide for the Best Computer Power Supply

Finding the best power supply isn’t as difficult of a task if you know what you’re looking for. Trust us, if you keep these points in perspective, you will never regret your purchase.

Before you opt for a PSU, you need to figure out how much power you need to run your system. You need to understand that most computer components draw power from the PSU. So, if you have planned to add more components in the future, you will need a PSU to support the additional power draw.

We suggest calculating the wattage of all of the computer components that will be drawing from the source. It mainly depends on your CPU and your GPU or GPUs. Once you have a figure for each component, add them together, and you will have a combined wattage. So, whatever figure you get, make sure the power supply you purchase has a higher wattage in comparison.

How do you determine whether a PSU is efficient or not? It’s simple. A power supply converts the AC power into DC power. During this conversion, some of the power is lost as heat wastage. You need to find a power supply that converts at least 80 or 90% of the AC power to DC. You must have noticed above that all the models we recommended came with 80 plus certified ratings. That means they can convert more than 80% of the AC power to DC without producing a lot of heat wastage.

Single Rail or Multi-Rail
A single rail PSU has a single +12 Volts rail that feeds power to system components. Therefore, all of its power is available to any component in the system, regardless of the cable. On the other hand, a multi-rail divides its wattage between two or more +12 Volts rails. It cannot share power among different rails.

From a performance point of view, both work great and are safe to use. However, if you want to build a powerful rig, a multi-rail PSU will provide an additional layer of protection in case of a short circuit.

Having a PSU made out of high-quality components will produce an ample amount of energy. It will also have a better overall lifespan. Whereas, a cheaply constructed PSU won’t last long and also wouldn’t work well under heavier loads. Make sure the model you are buying is built out of high-quality components and can withstand added pressure.

Final Thoughts

So, this is everything we could gather on the best power supply for gaming computers. From the GPU to your CPU, everything in your system will only work as well as your PSU is. This is why you need to pay extra attention and money when buying a suitable power supply. We hope the article has been informative enough to help you make the most of your purchase. Thank you for reading.
