Best Power Supplies for Gaming PCs

The Asus TUF Gaming 750W Bronze power supply is the top model in the line of relatively inexpensive "bronze" solutions of the TUF Gaming series. Designed in accordance with the ATX 12V v2.3 standard, it is characterized by high stability with support for a wide range of input voltages (100 - 240 V) and a low pulsation level. And a fairly high load capacity of the + 12VDC channel with a power reserve of about 20% allows you to use TUF Gaming 750W in fairly powerful systems with a video card of the GeForce RTX 4070 Ti SUPER level and a processor like AMD Ryzen 7 7700X.

The technical architecture of the unit is based on a modern platform using a resonant LLC converter, active power factor correction (APFC) and separate DC-DC converters for the +3.3 V and +5 V lines. Such filling ensures voltage stability and minimizes pulsations even under high load. The energy efficiency of the model complies with the 80+ Bronze standard, reaching an efficiency of more than 88% at a load of up to 50%. Despite the "bronze" rating, the manufacturer emphasizes the use of Japanese military-industrial grade capacitors in key power circuits.

The TUF Gaming 750W is cooled by a 135 mm fan with Axial-tech technology and double ball bearings. It has support for semi-passive mode: at loads below 245 W, it turns off completely, providing absolute silence, and at higher load levels, it maintains a balance between effective cooling and acoustic comfort. Despite the lack of support for the ATX 3.0 standard, the device has four PCIe 6+2 connectors, allowing you to connect modern powerful video cards.

DeepCool PL750D is one of the first 80 PLUS Bronze class power supplies with support for the ATX 3.0 power standard and a separate 16-pin 12VHPWR cable for connecting NVIDIA RTX 4000 graphics cards. In terms of circuit design, power indicators and functionality, this is a thoroughbred workhorse, which is based on the OEM platform from Helly with a half-bridge topology based on two field-effect transistors, a synchronous rectifier and DC-DC converters of the secondary circuit.

Despite the use of inexpensive capacitors from ChengX, the PSU generally provides quite good electrical flow Rate with a moderate pulsation level and small drops under high load. A 120 mm fan with a plain bearing on a screw thread is used to cool the insides. At a moderate load of up to 400 W, it operates at low speeds, producing minimal noise. However, under high load, it accelerates exponentially and the maximum noise level can exceed 42 dB.

Despite its affordable price, DeepCool PL750D is equipped with an extended set of protection systems (OVP, OPP, SCP, OTP, OCP, UVP, SIP and NLO) and has a 5-year manufacturer's warranty. But due to the need to save on something, the manufacturer abandoned the modular format, so all unnecessary cables will have to be hidden. However, this is not such a problem, given that most modern cases are designed for the bottom placement of the PSU and the cables can be hidden in the HDD pocket, which most people do not need. On the other hand, the moderate length of the case (140 mm) slightly simplifies the assembly process.

The MSI MAG A750BN is the top model in the MSI Arsenal Gaming line, which is aimed at gamers and owners of high-flow Rate systems. This power supply unit complies with the ATX 3.0 standard, features reliable circuitry and 80 PLUS Bronze energy efficiency, and operates in a wide input voltage range from 100 to 240 V.

The unit is based on the CWT platform with a resonant LLC converter, synchronous rectifier and DC/DC converters, which provide stable output voltages on the +12 V, +5 V and +3.3 V lines. Thanks to the use of a modern component base, the device demonstrates a high level of reliability and low pulsations. A low-noise 120 mm fan with a sleeve bearing is used for cooling, which ensures a balance between temperature conditions and acoustic comfort. At a load of up to 300 W, the unit operates almost silently.

The model is equipped with a cable system with a traditional (non-modular) design, including PCIe 8-pin (6+2) connectors that support modern video cards with a PCI-E 5.0 interface. In general, the MSI MAG A750BN will be a good choice for users looking for a high-quality and stable power supply in an affordable price category.

The Chieftec Atmos CPX-750FC is a powerful 750W power supply unit that is ideal for gaming computers and workstations with high demands on reliability and flow Rate. The model complies with the modern ATX 3.0 standard and can handle peak loads of up to 200% of the rated power, which is especially important for powerful new-generation video cards with PCI-E 5.0 interface support. 80+ Gold certification guarantees a high level of energy efficiency - up to 90%, which reduces heat generation and power consumption.

Chieftec Atmos CPX-750FC uses advanced SRC Full-bridge topology with DC-DC converters, which ensures stable power supply with minimal voltage deviations even under high loads. And high-quality Japanese Nippon Chemi-Con capacitors largely guarantee the quality and durability of the power supply. The APW7159C controller is used for power management, and the IN1S429I-DCG microcircuit is responsible for safety, providing protection against overvoltage (OVP), overheating (OTP), low circuit (SCP) and excess current (OCP).

The cooling system is represented by a 120 mm Hong Hua fan with a hydrodynamic bearing. It has a low noise level and a long service life, and also supports the semi-passive ECO mode. At the same time, the power supply itself remains quite cool even under a long-term load of more than 80%. Plus, the model is equipped with modular cables, a wide range of protections and an official 5-year warranty. In combination with an adequate price tag, such a set turns the Chieftec Atmos CPX-750FC into one of the best solutions in its price segment.

be quiet! Pure Power 12 M is a modern power supply unit that combines high flow Rate, energy efficiency and functionality, making it an excellent choice for a wide range of users. The model has 80 Plus Gold certification with a declared efficiency of up to 93%. In addition, Pure Power 12 M supports the PCI-E 5.0 standard and is equipped with a 12VHPWR connector, which allows you to connect GeForce RTX 4000 video cards with a power consumption of up to 600 W without using adapters.

As a basis, the German brand chose a relatively inexpensive but well-thought-out HEC platform, built using LLC topology, a half-bridge converter and DC-DC converters for secondary lines. According to the manufacturer, it provides stable voltage with minimal deviations (no more than 2%), as well as a good power reserve (+ 25% of the nominal value). The device uses solid Teapo capacitors, as well as high-quality transistors made in Germany. Despite the absence of Japanese capacitors, which are common for many PSUs of the 80+ Gold class, a 10-year manufacturer's warranty and a wide range of protections confirm the high reliability of the device, allowing you to expect that it will survive several system upgrades.

All power cables are modular, so even at the assembly stage, cables for floppy disks and all other unnecessary "noodles" can be disconnected, simplifying the process of assembling the system. The proprietary Pure Wings 2 fan with a diameter of 120 mm with PWM control automatically helps to optimize the level of acoustic comfort and even working at full speed, the noise level does not exceed 26 dB, thanks to which be quiet! Pure Power 12 M can be recommended to users for whom silence is important.
