The Platimax box design and colouring is based around the platinum branding and colour scheme, associated with the 80 Plus Certification process.
Inside, the power supply is positioned in the middle of a cutout cardboard panel.
Inside is a user manual, cable tidies, a region specific power cable, mounting screws and a bag of modular cables.
The Platimax 850W isn’t a pure modular design. The images above show the modular cables (left) and the hardwired cables (right). Cabling is high quality 18 AWG sleeved. The main motherboard cable is 16 AWG.
