GTX 660 Ti looks almost identical to the GTX 670. The reference model is 9.5” or 24.1cm long. Since the GPU is like the one used on GTX 670 cards, Nvidia had to ensure adequate cooling. This is why the company used a quite hefty dual slot cooler, which is actually only about one centimeter shorter than the one on GTX 680. GTX 680, 670 and 660 Ti’s fans are the same type and size.

Just like on the GTX 670, Nvidia used a shorter PCB for the GTX 660 Ti. The company ended up using a shorter PCB, which is only 17.2cm long. At the same time, this is the reason why the power connectors aren’t at their standard spot, towards the end of the card. GTX 660 Ti cards come with two 6-pin power connectors. Inexperienced users often forget to connect the power cables. Thankfully, as of GTX 680, Nvidia started using low power notification message that is displayed at boot up and reminds the user to plug-in the power connector.


The following photo shows EVGA GTX 660 Superclocked Ti 2GB from the rear. EVGA is planning to launch 3GB versions as well.

Video outs include two dual-link DVIs (only one is VGA capable) and standard HDMI and DisplayPort connectors. Note that all four outs can be used simultaneously.

The GTX 670 comes with two SLI connectors usually found only on Nvidia’s high end cards. This means that users can daisy chain more cards in a Quad GTX 660 Ti system. We're actualy not sure whether Quad SLI is possible, since Nvidia officially supports only 3-way SLI, however, we're talking about driver restrictions, so anything is possible. If you remember the 301.42 driver adds Quad SLI support for GTX 670.
