The Corsair TX550M is at a decrease stage in Corsair’s portfolio than the RM550x, so naturally, it has to have a decrease total efficiency, to not create any issues for the latter. Nonetheless, it achieves excessive sufficient efficiency, and it is not noisy, even below harsh circumstances. If you do not have an issue with its semi-modular cable design and discover it at an affordable worth, go for it. Items just like the RM550x and the be quiet! Pure Energy FM 11 maintain the TX550M out of our finest energy provides.
We now have already reviewed the 650W and 750W members of Corsair’s TX-M line, so we thought to additionally put the smallest member, with 550W, to the take a look at. Because of the restricted depth of 140mmn, all TX-M fashions have compact dimensions and use a semi-modular cable design. They’re rated as Gold by 80 PLUS and Cybenetics, and the TX550M has a Cybenetics A (20-25 dB[A]) noise ranking. Lastly, the OEM behind these models is Nice Wall, which additionally supplies Corsair’s SF fashions.
The TX550M comes with a 120mm fan, which makes use of a rifle bearing. This isn’t the very best bearing kind. Nonetheless, it’s means higher than a plain sleeve bearing, and it does not value as a lot as a fluid dynamic bearing. Though the PSU makes use of a contemporary platform, it can’t ship full load at 12V, on paper not less than, which is bizarre. All PSUs that includes DC-DC converters mustn’t have an issue delivering full load at 12V with a minor load on the minor rails since, in essence, the rail offering energy to the minor rails is the 12V one.

The one mounted cables are the ATX and the primary EPS, that are important. The opposite cables are modular. It’s good to see two EPS connectors on a 550W unit, together with a pair of PCIe connectors, though the latter are on a single cable.
That is the primary time we see a PSU having extra 4-pin Molex connectors than SATA ones. There must be extra SATA connectors. On high of that, the space between the peripheral connectors is simply too brief at 95-100mm.

Regardless of its small dimension, the PCB shouldn’t be densely populated, permitting good airflow between components. The platform is offered by Nice Wall, the identical OEM that builds Corsair’s SFX models (SF sequence). All components are of top quality, and the mounted wires are put in in such a strategy to block as much less as potential the airflow on the secondary facet. On the first facet, we discover a half-bridge topology and an LLC resonant converter, whereas on the secondary facet, a synchronous design is used together with DC-DC converters for the minor rails.
The transient/EMI filter has all vital components, with an extra CM choke, and it does a very good job in suppressing incoming and outgoing EMI emissions. There’s additionally an MOV and an NTC thermistor supported by a bypass relay, for safeguarding towards voltage surges and enormous inrush currents.
The one bridge rectifier can deal with as much as 15A A of present at 100 levels Celsius, so it should simply cowl this PSU’s wants.
The APFC converter makes use of two FETs, offered by STMicroelectronics, and a single CREE diode. The majority caps are of top quality since they’re offered by Rubycon, whereas the APFC controller is a Champion CM6500, supported by a CM03AX.
The principle FETs are by STMicroelectronics and are put in right into a half-bridge topology. There’s additionally an LLC resonant converter to spice up effectivity. The resonant controller is a Champion CM6901.
4 FETs are utilized by the 12V rail. There’s room for 2 extra for increased energy output. A small warmth sink on the enterprise facet of the PCB helps them settle down. A pair of DC-DC converters regulate the minor rails.
The few electrolytic caps are of top quality. Just like the electrolytic ones, all of the polymer caps are made by Japanese producers.
The standby PWM controller is a Energy Integrations TNY278GN IC.
The small modular board hosts 4 polymer caps. There’s area accessible for 4 extra, and two further sockets.
The principle supervisor IC is an IN1S429I-SCG, which is semi-hidden by the polymer caps of the DC-DC converters.
Soldering high quality is sweet, though there may be not a lot to see on this facet of the PCB.
The NR120L fan makes use of a rifle bearing, so it should final for lengthy. It is a low velocity fan, so noise output might be decreased even below excessive working temperatures and elevated load ranges.
