Here is what Seasonic has to say about their new FOCUS PLUS 650W Gold PSU:
“Due to its small form factor the FOCUS PLUS Gold 650W power supply is a great solution for those who want to build smaller systems and care about the airy arrangement inside their computer case. The fully modular cables are easy to install, save space inside the computer case and provide ample customization and upgrading possibilities at the same time. This mid power range power supply is not only small, but mean too. It boasts the highest power density in its class and it also has remarkable stability and output characteristics during operation.”
