The Seasonic G Series 550W Power Supply ships in a very dramatically designed box, like the 360W version of the supply. No image of the unit on the front of the box, just an 80 Plus Gold logo bottom right.
Seasonic bundle a case sticker, mounting screws, user manual, regional specific power cable and cable ties. They include a cable bag to store the modular cables. Always handy to have.
The G Series 550W isn't a pure modular design and a single thick cable emerges from the front of the chassis. This features the main M/B cable and an EPS12V/ATX12V cable. The cables are all ‘flat' ribbon style, to help improve air flow. The G-550 has the same cable configuration as the G-450, including two 6/8 pin PCIE connectors – suitable for a single high end graphics card.
