ASUS GeForce GTX 670 DirectCU II TOP review - Product Showcase

The GeForce GTX 670 has a maximum power consumption of 170 Watts (give or take a little), you'll need to power the card with two 6-pin PCIe PEG lead from your power supply. Due to the small PCB the connectors look a little oddly placed, but that is because the cooler is longer than the actual PCB. The card will have a Digital VRM circuitry (DIGI+). The GPU gets 6 power phases assigned and the memory another 2 separate phases.

Power supply wise we recommend a 550 power supply to start with, with one card of course.

The GeForce GTX 670 PCB measures 27cm / 11" in length with the cooler. 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, the cooler design however will vent air into the chassis. ASUS also applied a backside plate covering the PCB. it makes the card very sturdy.

Once the ambient air has been used to cool the GPU, the hot air will be blown only partially outside the PC through the exhaust as you can see above the monitor connectors. However most of the heat will be blown into the chassis itself as the cooling casing is open at close to the PCB and rear side. Make sure you have proper ventilation inside the PC chassis... always.
