Seasonic Core GX 850 ATX 3 Review

The Seasonic Core GX 850 ships in a brightly yellow accented box – no high resolution images of the power supply are on show, it is just a generic design with a modest 7 year warranty listed on the front and the 80 Plus Gold Certification badge on display. Yet again, no Cybenetics badge approval on the front which is surprising to see.

The rear of the box lists some key features – including an efficiency graph and the ‘optisink' design.

Inside the box, the power supply itself is protected between foam blocks. The accessories and cables are set to one side along with some literature on the product.

The box contains some cable ties, screws for mounting, a regional specific power cable and some literature.

The table above shows a list of cables for each of the units in this range. The 850W power supply I am reviewing today seems to have enough cables to suit a wide variety of mid power demand gaming systems. The cables are individually braided and look pretty good.

The 12VHPWR connector is marked with “H+” and the 12V-2×6 connector is marked with “H++” to indicate a pin/terminal that supports 9.2A or higher current. Both connector types support up to 600W output power.
