Best Silent PSUs

The Gamemax GP-550 White 550W power supply unit offers increased reliability and efficiency at a budget price. It complies with the 80+ Bronze class and guarantees an efficiency of up to 85% due to the use of high-quality components (high-temperature capacitors, cooling radiator, controller) and an active power correction circuit (APFC). One +12V line is used, which can withstand a load of up to 456 W. This is not the highest indicator, but the overall potential of the PSU is quite sufficient for an entry-level gaming PC, as well as a reliable and quiet home assembly. The safety of all components of the system unit is guaranteed by a comprehensive protection system against low and high voltage, power surges, line overloads and short circuits. The official manufacturer's warranty is 5 years, which is a high indicator.

All design elements are white to create a PC with a corresponding concept. The optimized 140 mm fan with automatic rotation control (AFC) deserves special attention. The noise level under load does not exceed 25 dB, and is completely absent when idle. Thin and flexible cables in the form of loops facilitate installation in hidden niches and are long enough for use in Full Tower cases.

The SilverStone Essential ET550-B power supply unit complies with the 80+ Bronze standard and has good energy efficiency. It is an affordable alternative to expensive branded PSUs when assembling entry-level and mid-level PCs with a small power reserve for subsequent upgrades. The presence of active PFC ensures efficiency at 85% at half load and stable operation at maximum in 24/7 format. A competent internal design with the use of radiators prevents overheating. Parameters are controlled using OVP, OPP, OCP, SCP, OTP mechanisms, so the customer can be sure of the safety of components in the event of unexpected power failures. With a total power of 550 W, the load on the + 12V line can reach 504 W. The power supply can easily handle a combination of a modern processor and a video card (for example, AMD Ryzen 7 Granite Ridge 9700X OEM + Gigabyte Radeon RX 7600 XT GAMING OC 16G), leaving some headroom for overclocking.

The ATX form factor with a small depth fits most standard cases, and long cables are compatible with the largest Full Tower form factors. Flat cables with a flexible structure will fit perfectly into hidden niches to enhance the internal aesthetics of the system unit. The 120 mm fan optimizes the air flow for cooling depending on the load. This approach allows you to extend the life of the bearing and reduce the noise level to a minimum of 18 dB when the system is idle or simple operations are performed (searching for information, working with documents, viewing photos, playing music).

The Inter-Tech Argus APS-620W power supply unit is designed in a standard ATX format and fits most Midi / Full Tower system units. The manufacturer used an interesting combination of a black case with a yellow 120 mm fan. The latter supports automatic speed control (AFC) and guarantees a minimum noise level of 19 - 21 dB. The power supply unit will not cause discomfort when placing the computer on a desktop. The set of connection connectors covers the needs of any entry-level home or office assembly, although with a declared power of 620 W, an additional 8 PIN line for a high-performance video card would not be superfluous.

The manufacturer claims an efficiency of 86%, balanced heat dissipation and high energy efficiency, but the power supply does not have 80+ certification, which may raise questions about the actual indicators. In defense of the power supply, it is worth noting the presence of active PFC, which should provide all this functionality and is an indicator of good efficiency at any load level. The main +12V line can withstand the connection of modern processors and video cards with a total power of up to 570 W (it is recommended to leave a reserve of about 30% to prevent wear and tear). The electronic power supply circuit implements only basic security systems (OVP, SCP, OPP, UVP).

The be quiet! System Power 10 BN327 power supply unit is part of a series of devices from the company with an optimal balance of quality, performance and cost. The model is aimed at mid-range personal computers that are aimed at professional media content processing, application development, 3D graphics and gaming. To connect the corresponding components (processor, video card), a + 12V line is implemented, the load on which can reach the declared total power of 550 W. Moreover, the power supply circuit provides two 8 PIN PCIe lines for an advanced graphics adapter of the Radeon RX 7700 XT or GeForce RTX 3070 series. The main advantage of the PSU is active PFC, which guarantees maximum efficiency of 89%, reduced heating and power consumption. The declared performance characteristics are confirmed by 80+ Bronze certification, as well as an official 5-year warranty. Considering all the features and popularity of the brand, the cost of the power supply can be considered quite affordable.

be quiet! System Power 10 BN327 does not require configuration and control. The operation is fully automated and minimizes the likelihood of failures. An extended set of protection systems (OTP, OCP, UVP, SIP, OVP, OPP, SCP) eliminates the failure of both the power supply itself and the connected components. The company is famous for the quiet operation of the equipment, which is confirmed by the declared noise level of about 10 dB at a load of 50%. Fan speed is adjusted automatically to maintain the optimum temperature.

The be quiet! Pure Power 12 M BN341 power supply demonstrates high efficiency at 93% and has been certified according to the 80+ Gold standard, which indicates the reliability and energy efficiency of the power conversion circuits. It is worth noting right away that the manufacturer's warranty is 10 years, so you definitely don't have to worry about its performance. The main goal of the brand is to create quiet power supplies, and to implement this concept, well-thought-out temperature control systems are used (automatic speed control, additional radiators, components with low heat generation). The model does not require powerful cooling, so the optimized 120 mm fan guarantees a noise level of only 8 dB at an average load.

The company focuses the power supply on high-performance PCs for professional gaming and any customer tasks. A separate 16 PIN line (12VHPWR) allows you to connect top-end video cards with support for the PCIe 5.1 standard and a power of up to 300 W. The total load on the +12V line can reach 550 W. There are also 2 PCIe 8 PIN connectors (6 + 2) that are compatible with all graphics adapters. The power circuit provides additional conversion mechanisms (MOS transistor cascade, LLC, DC-DC), which guarantee an almost perfect sinusoidal power at the output of each line. The model is capable of withstanding short-term peak power of up to 600 W without shutting down. Comprehensive performance monitoring is provided by smart protection systems (OTP, OCP, UVP, SIP, OVP, OPP, SCP). Input and output parameters are monitored by the controller to prevent failures in a timely manner. Enthusiasts and hobbyists will appreciate the modular cable design for easy PC assembly and minimal cable clutter in the system unit. They are designed as thin, flexible cables for hidden cable management.
