If you need the extra goodies Enermax provides with the Enermax RevoBron TGA 700 W, it is a good deal. Besides the PSU and its special paint job, you will get three RGB fans, an advanced controller, and all the necessary cables to install them in your system. However, if you don't care about the extra fans and controller, there is better since you can get a more efficient unit with better performance, like the Seasonic Focus Plus Gold 750 W or Corsair RM750x, for the money, and the Corsair RM750x features a much quieter operation as well.

The ERB700AWT is based on a solid platform by Channel Well Technology that uses quality components. However, the design is old and cannot compete with modern platforms featuring half and full-bridge topologies, LLC resonant converters, and synchronous rectification in the secondary side. While Enermax uses Japanese caps and a good quality fan to improve the platform's reliability, even those parts cannot improve overall performance since the design sets the limits here. Transient response is mediocre, load regulation at +12V is not tight, and efficiency levels cannot compete with modern units that are 80 PLUS Gold and/or ETA-A certified.

In my opinion, although the RevoBron TGA 700 W is a good choice for anyone wanting to score a nice and affordable bundle consisting of the PSU, three RGB fans, and a good fan controller, users should still go for nothing below 80 PLUS Gold and ETA-A efficiency. We should all restrict our energy needs for thousands of reasons outside of the financial benefits, and the only way to do so is by using energy-efficient products, which is where power supplies play their key role, of course. A few years ago, 80 PLUS Gold and Platinum ETA-A and ETA-A+ platforms were expensive, so inevitably, the lower efficiency models dominated the market. But this is not the case anymore since $100 can get you a very efficient, fully modular PSU, although without the extra goodies the RevoBron TGA 700 W includes. Apparently, you cannot have it all, so it is up to you to choose.
