FSP Guardian Software

The interface of FSP Guardian's software is plain, which isn't necessarily a disadvantage. Plain interfaces are more intuitive than complex ones, and while a complex interface might provide more functions, your average user won't use all of them.


Here's the program's home screen. You can check on the total power output of all rails, the current and accumulated operation time, total electricity cost, and the frame's temperature. There are also two indicators for the modules' functionality. When those indicators are green, everything is fine, and red does, as per usual, stand for trouble.

Each module has its own status section where you can monitor the input voltage and current, the +12V rail's output voltage and respective current, fan's speed, and the temperature inside the module. We'd like FSP to add an efficiency reading, along with a reading for the 5VSB rail's state. There aren't any control options, either. It would be good to have the ability to modify the fan speed's profile, especially for such a noisy PSU as this one.


The app's second tab is where you'll find the system log, which provides access to previous records and graphs for the data pertaining to each module.


The product's information is shown here, along with the firmware and software versions.


This menu allows you to set the cost of electricity, preferred temperature of the unit, and the software's color settings. It's also possible to check on whether the modules' LED indicators are working properly. When you slide the button in the "Modular Indication" frame to the right, the corresponding module's LED should start blinking. If it doesn't, something is wrong.
