Under the Hood
Here are a few pictures showing the layout and components inside the Corsair TX850W power supply. The overall layout looks quite good with components neatly organized and plenty of open space for good airflow.
Unlike Corsair’s previous HX520/620 and the VX450 power supplies which were built by Seasonic, the TX series is manufactured by Channel Well Technology (CWT) who was also the OEM for the VX550. CWT has a good reputation in the industry for producing high output power supplies and the TX850 is based on one of CWT’s most popular platforms. It will be interesting to see how this particular unit tests out and whether or not Corsair has enabled CWT to engineer out a few of the weaknesses that have plagued this platform in the past.

The primary side features a single, large Nippon Chemi-Con electrolytic capacitor rated for 470uF, 450V, and 105°C. The secondary side also uses high-quality Nippon Chemi-Con caps for reliable service. Overall, very good choices for capacitor selection; just what we would expect from Corsair!

Note the use of a plastic guard protecting the cable bundle as it exits thru the back of the power supply. This is a simple feature that is too often overlooked by the majority of power supply manufacturers.
I’ve had it for 13 years and it’s still good, never issues. I’m not planning to change it yet, but maybe I will have to because of a new case.
I’ve had it for 12 years and it’s still good also. And I’ll stick with for a while longer since my next card will be a RTX 2060, so no worries so far. Amazing PSU.
i using this PSU since 2011, almost 13 years in operation and waiting if it can power a 4070 Ti Super, fingers crossed.
*i’m using
15 years old and still ticking. I’d say this PSU has stood the test of time!
