Compared to its predecessor (HX850 Silver) the HX850 Gold has been given some subtle modifications to its external housing. Each side features the model branding so that regardless of which orientation you go with the text will always be correctly displayed. Quality, look and feel of HX850 is professional and very good.
An overview of HX850
HX850 uses an ultra-quiet, 140mm double ball-bearing fan which from the outside has a circular fan grille with the Corsair logo in the centre. More on the brand/model later when we open the unit up.

Due to HX850 being a modular PSU there is a panel next to the hardwired cables for attaching specific cables that you require for powering the system. There are 4x blue slots for PCI-E and 6x black slots for peripherals/HDD.

On the alternate side to the cooling fan is the specifications label which details maximum load along with critical information such as ampage for the PSU rails. The +12v rail will be the rail most will be interested in due to it feeding through the power for the graphics card, the +12v rail has a burly 70A which is more than capable of handling two high end solutions NVIDIA SLI or AMD CrossfireX.
Also on the specifications label is the serial number and certifications/standards.
