How Does a Quiet Power Supply Work Differently Than Other Power Supplies?
To understand the difference between a quiet power supply and a not so quiet one, it’s important to understand how they truly work. Mainly, the power supply unit converts the main AC to low-voltage DC for the computer’s internal components to operate with.
However, during this process inevitably, some heat is produced, which puts your power supply unit at risk of being overheated. To aid the situation, one or two fans are employed. Thus, due to the airflow and fan bearing, noise is produced.
Now, a quiet power supply can get ahead of this situation and reduce fan noise without compromising its efficiency. Quiet power supplies are equipped with temperature-controlled technology, which produces minimal heat when less power is consumed. It might also have fans specially designed to adjust their RPM according to temperature. However, as far as their counterparts are concerned, they are equipped with no such technology and can get very noisy.
How to Choose a Quiet Power Supply
One of the most frequently asked questions is how to choose a quiet power supply. Well, there are certain features and factors one should look into before buying one, which makes up a top-of-the-line product. These ensure the product stands out from others.
Wattage
It's crucial to understand the wattage you need to fulfill your power supply needs. It’s not necessary to get the highest wattage possible as it would just be a waste of money. In fact, it's better to calculate the amount of power your system will overall draw and look for a unit that satisfies that.
Quality and Performance
Make sure that the unit you invest in has good-quality construction. This is important because poorly built units often use thin and cheap metal housing, which tends to vibrate more and create more noise than well-built models. Thus, the quality of construction can greatly affect the power supply’s performance.
Fan
The shape, construction, and design of the fan plays a crucial part in reducing noise and successfully controlling temperature. Therefore, take into account the fan-bearing diameter and opt for one which is designed to be quiet while operating. Furthermore, opt for a unit that has the right fan shape and design to optimize airflow and reduce cable clutter.

There are several products in the market; however, not all of them are worth your time and money. It can be pretty troublesome finding the perfect one; thus, to help you with that, we have reviewed and listed some of the best quiet power supplies in the market.

People Also Ask
When it comes to buying power supplies, several questions come to mind, especially for first-time buyers. These often cause confusion to them; therefore, to clarify these, we have answered some of your most frequently asked queries.
Why Are Power Supplies So Loud?
As the main AC is converted to low-voltage DC to be used for your computer’s internal components, a certain amount of heat is produced. To avoid overheating, power supplies are equipped with fans that regulate temperature by cooling down the environment. However, the process can be a noisy one due to fan bearings and airflow.
What Decibel Level is Considered Quiet in a Power Supply?
Any noise for a prolonged time which exceeds 70 dB is damaging to your ears. A whisper is about 30 dB, whereas a running motorcycle engine is about 95 dB. Furthermore, every sound that exceeds 85 dB will require you to wear ear protection. For a normal and comfortable environment, the ideal sound range is 30-40 dB.
Are be quiet! Power Supplies Good?
Yes, be quiet! power supplies work pretty well.
Do Quiet Power Supplies Operate at Lower Voltages?
If a quiet power supply doesn’t have enough voltage, your PC may run into some system instability issues.
