The Sparkle Calibre X680 Captain ships in a very sophisticated oblong container, plain black with a logo in the center and the ‘Calibre' name highlighted top left and ‘Designed By Sparkle' in the center at the bottom of the box. We were almost expecting to see a 3D render of a toothless Pirate Captain on the box, but the company have opted for a unicorn mascot instead.
The bundle includes several power and video converters, a quick install guide and a VIP support card with the same unicorn mascot emblazoned at the top.
The Sparkle Calibre X680 Captain is certainly eye catching, as upon first glance there are no fans installed. On closer inspection we can see they are underneath the aluminum heatsink.
On the opposite side of the two slot cooler there are several bars bolted into place to ensure that the cooler maintains enough distance from the PCB, otherwise the fans would hit components on the card. The rear of the PCB shows a backplate which will help improve cooling efficiency under load.
The card really is very attractive, the six heatpipes are arranged in a radial layout, spreading across the full length of the heatsink from left to right.
The Sparkle Calibre X680 Captain is SLi capable in 2, 3 and 4 way configurations.
The card takes power from a single 8 pin and 6 pin connector.
There are two DVI ports on the back, along with an HDMI and DisplayPort connector. This is a perfect configuration of digital video connectors and covers all bases.
The cooler is very well constructed with 3 fans bolted into the heatsink from the underside. The base is connected to six thick heatpipes which span the full width of the PCB. The GDDR5 memory and VRM's are all treated to dedicated coolers which earns the Sparkle Calibre X680 Captain a bonus point.
