This PSU receives a 91% rating for its great power at a very affordable price, but at the cost of some efficiency.
"Back in 2008, Corsair launched the TX series of power supplies. It was an instant success and a power supply that many still love today. It provided plenty of power for gamers and enthusiasts and did so without breaking the bank. The TX series also offered great connector availability and longer cables for those with larger cases and those that routed cables to keep them from being seen. Corsair has been updating several of their power supply series and the TX series is the latest in the line of refreshments.
Fast forward to today and we now have the Corsair TX Version 2. The specific power supply on the bench right now is the Corsair TX850V2. On the surface, the TX850V2 differs little from its predecessor. Connector availability remains the same and if it wasn't for the sticker denoting it as a TX850V2 instead of a TX850W, you probably wouldn't know they were different. Corsair took a good look at the internals and decided to make some changes there, bringing with it improved efficiency and higher quality DC output. Read on as we take an in depth look at the Corsair TX850V2."
