The ASUS TUF Gaming 550W Bronze is a budget-oriented PSU that manages to attain high-performance because of the trendy platform that it makes use of. However, the competitors is tough. Though models just like the XPG Pylon 550, Corsair CX650M, and Thermaltake Good BM2 550 use less-advanced platforms, they nonetheless take the lead in total efficiency, leaving no room for the TUF Gaming 550 to earn a spot in our greatest PSUs article.
The TUF-Gaming collection consists of 4 PSU fashions with capacities starting from 450W to 750W. The mannequin we’re evaluating right here has 550W max energy, best for a a small dwelling PC with a mid-end GPU or a business-oriented PC with an embedded GPU. To maintain the manufacturing value low, ASUS used a non-modular however trendy design supplied by Nice Wall. This is identical platform discovered within the Corsair CX line, which has been changed by the CX-M line which may make the most of a semi-modular design but additionally makes use of a much less superior platform than CX.

The TUF 550 is 80 PLUS Bronze, and Cybenetics Silver licensed in effectivity. In noise, it acquired a Cybenetics Normal++ ranking, which isn’t so flattering for a low-capacity PSU, particularly one utilizing a contemporary platform. Its dimensions are commonplace, with 150mm depth, permitting the set up of a 135mm fan.

The platform is trendy. Usually decrease effectivity models use older platforms, with the one trendy contact being the DC-DC converters on the secondary facet. On this case, although, GW used a half-bridge topology and an LLC resonant converter, a design that we meet in larger effectivity platforms. Furthermore, a synchronous design regulates the 12V rail on the secondary facet.
The numerous compromises that needed to be made to maintain the price low had been the low-quality bulk and filtering caps and the fastened cables. We do not thoughts a lot in regards to the latter, however we do thoughts the Lelon caps.

The transient/EMI filter has all require elements and it does an virtually good job.
The only bridge rectifier can deal with as much as 15A at 100°C.

The APFC converter makes use of two FETs and a single enhance diode. The majority cap is rated at 450V and 105°C, however its capability is low, and to make issues even worse, it’s by Lelon, which isn’t among the many good capacitors manufacturers.

The first switching FETs are two STMicroelectronics put in in a half-bridge topology. An LLC resonant converter can be used for elevated effectivity.

4 FETs regulate the 12V rail and a pair of DC-DC converters deal with the minor rails.

The filtering caps are principally by Lelon and Teapo. The Lelon caps have good specs. Nonetheless, we would favor if all caps had been by Teapo.

The standby PWM controller is a TNY278PN IC. The rectifier on the secondary facet of this circuit is an SBR.
The principle supervisor IC is an IN1S429I – DCG.
