The Asus TUF Gaming 450W Bronze is a low-capacity, affordable PSU for systems with low power demands. If fixed cables aren’t a big deal, it should be on your purchase list as it offers high performance thanks to the latest platform it uses. Whenever the price is right it includes the value conscious XPG Pylon 450 Can compete with the best PSUs.
The lowest model in the Asus TUF-Gaming line has a maximum power of 450W, making it ideal for office PCs and download stations with low energy demands. From that moment on, Corsair decided to replace his CX line with semi-modular CXM units. It’s not advanced, but still uses a capable platform. Asus is the only one to offer a bronze efficiency (silver by Cybernetics) PSU and feature a half-bridge topology. and LLC resonant converters. Corsair has removed this platform due to increased costs. Other major brands such as XPG and Thermaltake also used older designs with some updates to achieve similar performance.

Like the TUF 550, the TUF 450 has 80 PLUS Bronze and Cybenetics Silver efficiency certifications. In noise, Cybernetics received an A- rating. This is good enough for a low capacity PSU. Finally, the TUF 450 has a compact footprint with a depth of 150mm, allowing you to install a 135mm fan. The smaller volume of the unit allows for a smaller chassis, but this does not allow for fans larger than 120mm, which impacts noise output.

This platform is too advanced for a mere bronze unit and therefore more expensive. His OEM behind the TUF line, Great Wall, used a half-bridge topology and an LLC resonant controller. Typically found in gold and higher efficiency units, and in some cases even titanium. The soldering quality is excellent, and to keep costs down, GW used Elite and Tipo caps, which are the best substitutes for Japanese caps.

Transient/EMI Filter has all the parts needed to get the job done.
A single bridge rectifier can handle up to 15A at 100°C.

APFC converters use two FETs and one boost diode. The bulk cap is rated at 450V and 105°C, but its capacity is low, and to add insult to injury, it’s by his Lelon, a lesser-known brand in this section.

The primary switching FETs are two STMicroelectronics installed in a half-bridge topology. LLC resonant converters are also used to increase efficiency.

Two FETs regulate the 12V rail and a pair of DC-DC converters handle the minor rail.

Electrolytic filter caps are mostly by Elite and Teapo. On the 550W unit, we found some Lelon caps to be inferior to similarly spec Teapo and Elite caps.

The standby PWM controller is TNY278PN I C. The rectifier on the secondary side of this circuit is an SBR.
The main supervisor IC is IN1S429I – DCG.

The cooling fan uses double ball bearings. Low-quality fans are usually found in his low-priced PSUs.
