Overview

PC builders often aim to purchase a dependable and efficient power supply unit (PSU). Still, because of technological advancements, there are now an increasing variety of silent PSU solutions that weren't previously available.

Most power supplies employ fans to dissipate heat, which is where that annoying buzzing noise originates.

Despite this, manufacturers can use hybrid versions or fanless designs to reduce the sound output of a PSU. Finding the best, most noise-free power supply for your build might be challenging regardless of the PSU design you are considering. So, the following article provides users with 20 Best Quiet Psu in 2024.

Reviews

1. Seasonic Prime 600 Titanium SSR-600TL

Product’s Specifications

  • Connector Type: ATX12

  • Output Wattage: 600

  • Form Factor: ATX12V

  • Wattage: 600 watts

  • Item Weight: 1 Kilogram

  • Power Supply Design: Full Modular

Product’s Highlights

It's reasonable to state that Seasonic is one of the most dependable manufacturers on the market because they are well renowned for their power supplies. One of the best quiet power supply money can buy is the SSR-600TL. This powerful PSU outperforms many of its rivals and can easily support a top-tier gaming system.

The only fanless Seasonic model available is in the Prime series, and it is one of the fanless PSUs with the maximum available capacity.

Despite being a fanless PSU, the Seasonic Prime can be used in a high-end gaming system because of the unit's large capacity and variety of connector options. This PSU makes up for its lack of active cooling with an efficiency level of 80+ Titanium. Without a doubt, in this capacity, this is among the best passive PSUs available. If you can afford the SSR-600TL's price tag and want your PC to run silently, look no further!

Pros

  • Well performance

  • Resilient to high temperatures

  • Good build quality

  • Silent

  • Reliable

  • Fanless

Cons

  • Expensive

2. Corsair RM750x

Product’s Specifications

  • Output Wattage: 750 Watts

  • Form Factor: ATX12V

  • Wattage: 750 watts

  • Item Weight: 4.25 Pounds

  • Power Supply Design: Full Modular

  • Maximum Input Voltage: 230 Volt

Product’s Highlights

A very popular wattage that combines the power of top-tier hardware with affordable costs is 750W. Most people will undoubtedly have enough power. And one of the models from Corsair's well-known RM series is now the finest of the group. There are no tangled cords because it is modular. It is LAMBDA-A+ certified and has an efficiency rating of 80 Gold Plus. Additionally, it has a remarkable 10-year warranty.

It is pretty well made. A microcontroller and rifle bearing-equipped 135mm fan reduces noise. The ATX, EPS, and PCIe cables are also equipped with capacitors to lessen ripple.

These were successful because all rails had excellent ripple suppression.

This PSU's volume is really stunning because it is so quiet!

Its typical noise level (between 30 and 32 degrees Celsius) is only 19dbA. Seasonic's SSR-750FX 35, one of its key rivals at this price point, was almost twice as loud at 35dbA.

A 10dbA increase represents a two-fold increase in the apparent volume of human ears, which is more than 1.5 times the noise.

Corsair's model even achieves near-silence at full load or overloads, which is even more impressive. It only reached 30 dbA at full load at 46 °C, as opposed to the Seasonic SSR0750PX's 45 dbA.

Pros

  • Quality components

  • Well voltage, ripple noise

  • High efficiency about 90% (80 Plus Gold)

  • Quiet

  • 10-year warranty

Cons

  • Perhaps 750W is insufficient for high-end gaming.

3. CORSAIR HX850 Series

Product’s Specifications

  • Form factor: ATX

  • Capacity: 450W

  • Efficiency rating: 80 Plus Gold

  • Modularity: None

Product’s Highlights

For the price, its 80 plus Gold efficiency rating is fantastic. Even within this, it tested more efficiently than 89%, outperforming most rivals.

It has a LAMBDA-A++ certification and is remarkably silent, which is shocking given its low price and the fact that it lacks even a little 120mm fan and a semi-passive mode.

This is because of its superb construction. Because of its efficient energy management, this PSU operates at a low temperature, which enables the fan to run slowly and quietly.

The noise level was under 40dbA even at 100% load and over 46°C. Below this, the fan rarely turned at its fastest speed and frequently at its slowest.

The three +12V rails can deliver 450w, while the 5VSB rail can deliver up to 2.5A.

Each rail has excellent ripple suppression. However, the EVGA 450 B3 takes the lead in this regard. Capacitors on the ATX cable aid in reducing ripple on the PSU outputs.

Performance outperformed other well-known 450 models (Corsair, EVGA), which is behind the Seasonic SSR-550X only very marginally.

At least the PSU is relatively small, measuring only 150 x 87 x 140mm, making installation simpler.

Pros

  • Very efficient

  • Full protection features set

  • Extremely silent

  • 10-year warranty

  • Compact, excellent design

Cons

  • Not modular

4. EVGA's SuperNOVA 650 G3

Product’s Specifications

  • Form factor: ATX

  • Capacity: 650W

  • Efficiency rating: 80 Plus Gold

  • Modularity: Full

Product’s Highlights

For video editing at resolutions of 4K and above, 650W should be adequate.

And this is among the least expensive 650W 80 Gold Plus models available. It represents a very exceptional value, particularly for video editors who have likely already invested considerably in a powerful CPU and GPU.

Contrary to what you might expect, it has one of the most outstanding overall performances among all 650W 80 Gold Plus models, including Corsair and Seasonic.

Furthermore, the Super Flower construction is excellent (Super Flower is among the best in the industry), with top-tier ripple suppression and extremely tight load management on all rails.

The minor rails are capable, the 5VSB rail can produce a huge 3A, and the +12V rail delivers the entire PSU's capacity.

But it has a LAMBDA-A- noise certification for noise levels. Although this isn't the best, it doesn't imply it's "noisy." Its average noise level is 27.31 dbA. This is noisier than comparable versions from Corsair, for comparison.

The 130mm HDB fan's tendency to rotate more quickly than most at cooler temperatures is a concern.

Additionally, there is only 1 EPS connector, 3 PCIe, 6 SATA, and 4 Molex, which may be problematic for some users.

It is reasonably portable with dimensions of 85 x 150 x 150mm and a good 7-year warranty.

Pros

  • Reasonable price

  • Well performance

  • High build quality

  • Full power at 47°C

  • Efficient

  • Relatively quiet with light to medium loads

Cons

  • Not the quietest

FAQs

1. Can a PSU be opened for cleaning?

Although most of the very minute dust particles will blow out the vent, some will still get inside the PSU. You are correct in saying that it can be risky if you decide to open your PSU. The best method is to remove, unplug, and let it alone for two to three days. Typically, this permits any accumulated charge to dissipate.

2. Does dust affect PSU?

The performance of the intake-fan and heatsinks may be hampered by excessive dust. The heatsinks may warm up if there is insufficient airflow from the fan or if there is dust on them.

3. How long does PSU last?

 A PSU should last long when used as intended—at least five years, and if you're lucky, up to 10 years. However, the power supply might become overstressed if excessive loads are applied to it repeatedly for extended periods.

Final Thought

Due to the restricted number of options available, choosing the best silent power source can be challenging. If you're unsure which PSU is best for you, be sure to check our Power Supply calculator. Whichever option you choose, try to acquire a little more wattage than you require, then turn off the fan!
