Review: Silent power

The I/O panel of the GTX 780 Ti HOF card contains four video connectors and three of them can be used at the same time. There is one standard HDMI connector (1.4a compatible), one standard DisplayPort out and two DVI outs (one single-link and one double-link).


The black button next to the video connectors is the Hyper Boost button - push it to spin the fans up to maximum. Hyper Boost allows you to drop the temperature in no time, with a short burst of high-speed airflow, with the accompanying noise of two 90mm fans maxed out.

Once we took off the cooler we could finally get a good look at the white PCB. White boards are relatively rare, since white PCBs cost more to produce.



The card has 3GB of GDDR5 memory and all the memory modules at the front of the PCB. The SK Hynix chips, (model H5GQ2H24AFR-R2C) are specified to run at 1750 MHz (7000 MHz GDDR5 effective).


The back of the card is covered by a big backplate.



The next picture shows the memory heatsink and the VRM heatsink.



The power circuit is designed as 10+3 phase. The card uses an CHIL CHL8318 voltage controller.


The big copper base (vapor chamber) has a lot to do with the cooler's excellent performance. A big chunk of the heatsink is straight over the base, while the rest of the fin array gets much of its heat through copper heatpipes.






The next pictures shows how cable routing was implemented. Both fans share the same 4-pin power connector. Setting the RPM manually is easy using any popular GPU utility.


The dual-pin connector next to the 8-pin power connectors powers the LED on top of the card, right under the Hall of Fame logo.


The Hyper Boost button has its own connector.
