PowerChute Version 5.0
PowerChute installs AdoptOpenJDK 11.0.16.1 for all supported operating systems

PowerChute Version 4.4.1, 4.4.2, 4.4.3
PowerChute installs OpenJDK 15 for all supported operating systems

PowerChute Version 4.4
PowerChute installs OpenJDK 14 for all supported operating systems.

PowerChute Version 4.3
With all supported operating systems except HP-UX^®, AIX^™, and Mac OS X^™, PowerChute installs OpenJDK 11.
To install PowerChute on HP-UX, AIX, and Mac OS X, a compatible JRE must already be installed on your system.
Solaris Sparc gives you the option of installing the bundled JRE, or specifying a JRE location.

PowerChute Version 3.x, and 4.0, 4.1, 4.2
With all supported operating systems except HP-UX, AIX, and Mac OS X, PowerChute gives you the option of installing a "private" JRE during installation.
However, this "private" version of the JRE, which is specifically for PowerChute, will take up about 100 MB of disk space. A PowerChute installation takes up about 6 MB of space if you have already installed a public JRE.
