Since our test equipment's limits are higher than that of the Corsair TX550M, we can test it to the maximum. It did not exhibit any concerning weakness under real world usage situations either, it was able to deliver over 600 watts of power before safety measures stepped in for a safe shutdown. Flat, sleeved black modular cables with clearly-marked connectors make installation fast and straightforward, with good-looking results. The Cybenetics organization measures efficiency and noise levels across the PSU’s entire operational range, using more than 1,450 different load combinations. While that is to be expected, the important thing to look at is where the cuts in outputs were made.

For consistent, reliable power and superb electrical performance, each TX-M Series power supply features a robust resonant LLC topology with DC-DC conversion and 105°C rated Japanese capacitors. Semi-Modular Cabling: Lets you connect the cables you need for a cleaner build with easy cable management, while dual EPS12V connectors ensure wide compatibility with modern graphics cards and motherboards.Sounds like it's probably advisable to add the second cable and sacrifice some cable management cleanliness. They've changed up the connector availability, added modular cables and made sure the unit was still of great build quality.

This is a great list of features to find in such a low wattage power supply and we will find a few things that you wouldn't expect. These units target a mass enthusiast audience running a modest gaming system with a single graphics card.It is very obvious that the cooling isn't the most spectacular that we've ever seen, but so long as it gets the job done and the unit doesn't fail under full load, we won't complain. Thermaltake ToughPower grand RGB750w 80+gold  Every CORSAIR power supply is designed by our California engineering team and built to our exact specifications. Due to public requests we changed our temperature settings increasing ambient temperatures by 10c (to 35c) in our environment to greater reflect warmer internal chassis conditions.

Low-Noise Operation: A 120mm rifle bearing fan creates less noise than traditional bearings, letting you focus more on the task at hand, whether it’s gaming or work.

The unit also achieves over 85% efficiency during Test 2 and manages to hang in there during the full load test with 83. Resonant LLC Topology with DC-to-DC Conversion: Provides clean, consistent power, reduces coil whine for quieter operation, and enables use of more energy efficient sleep states. While our first test is well above the 20% mark, the test does show that the unit is well above the 82% mark already.Credit is provided by Novuna Personal Finance, a trading style of Mitsubishi HC Capital (UK) PLC, authorised and regulated by the Financial Conduct Authority. i7 8700K, AORUS Z370 Ultra Gaming, 16GB DDR4 3000, EVGA 1080Ti FTW3 Ultra, Samsung 960 EVO 250GB, Corsair HX 850W. They happily sent over their new TX550M, the latest power supply in the TX series complete with modular support. That said, measuring lower than 28dBa proves very difficult, unless in strict laboratory conditions.
