With the GTX 670s power circuitry (4+2 phases btw) moved to the other side of the board, the area on the right side of the PCB was empty and was therefore removed to save board space. The GeForce GTX 670 has a maximum power consumption of 170 Watts, you'll need to power the card with two 6-pin PCIe PEG lead from your power supply.
We recommend a 550 power supply to start with, with one card of course. You will notice a somewhat unusual located power connector, it's indeed almost in the middle of the PCB.
The GeForce GTX 670 reference board measures 9.5 in length. Display outputs include two dual-link DVIs, one HDMI and one DisplayPort connector. The top part has been kept open for ventilation so that the card can exhaust hot air, and do exactly that... lots of it.
The GeForce GTX 670 has a similar cooler design that the GTX 680 also uses, inside the fan acoustic dampening materials have been used to prevent fan noise and unwanted weird tones, the cooler is now based of a triple heatpipe design and a customized fin stack shaped for optimal airflow. Once the ambient air has been used to cool the GPU, the hot air will be blown outside the PC through the exhaust as you can see above the monitor connectors. Make sure you have proper ventilation inside the PC chassis... always.
Today a review the EVGA GeForce GTX 780 SC ACX edition. The Superclocked model comes with a nice factory tweak and that all new Sleeve bearing fan based ACX cooler. Overall the card is almost as fast as a GeForce GTX Titan, 100% cool and 100% silent. We test the product with the hottest games like Metro: Last light, Battlefield 3, Sleeping Dogs, Far Cry 3, Medal of Honor Warfighter, Hitman Absolution and many more.
Gigabyte GeForce GTX 780 WindForce 3x OC review
We test and review the Gigabyte GeForce GTX 780 WindForce 3x OC edition. The graphics card comes witha factory overclock and the new WindForce 3X 2 Slot 450W fan sink with Triangle Cool fans, as they like to cool it. That would be three silent 80mm fans. Overall the card is almost as fast as a GeForce GTX Titan, 100% cool and 100% silent. We test the product with the hottest games like Metro: Last light, Battlefield 3, Sleeping Dogs, Far Cry 3, Medal of Honor Warfighter, Hitman Absolution and many more.
GeForce GTX 780 SLI and Multi monitor review
We review the GeForce GTX 780 SLI and also do a SurroundView session with three monitors. The boards used are reference from NVIDIA. Over the next few pages we'll tell you a bit about multi-GPU gaming, the challenges, the requirements and of course a nice tasty benchmark session with the latest games. We'll have a peek at temperatures and power consumption of the GeForce GTX Titan cards in 2-way SLI mode to monitor it's generated performance.
GeForce GTX 780 review
We test and review the GeForce GTX 780. The GeForce GTX 780 is NVIDIAs all new high-end graphics card based in their Flagship product, the GTX Titan. This means it is based on the GK110 GPU and has an whopping 7.1 Billion transistors. That makes it a nice chunk faster opposed to the GeForce GTX 680 GPU. We test the product with the hottest games like Metro: Last light, Battlefield 3, Sleeping Dogs, Far Cry 3, Medal of Honor Warfighter, Hitman Absolution and many more.
