The PCB of the gtx 660 GPU is 4.5” x (a little under) 10” and looking at the dimensions including the cooler is 5.5” x 10.7”. This card takes up 2 slots.



As a speciality of Direct CU II series GPUs, the card comes with dual fans and 2x heatpipe with direct heatpipe contact on the GPU core. As Asus claims, it helps to keep the card 20% cooler and vastly quieter.


From left: 1x DVI-I /Compatible connector to DVI-to-VGA converter with a DVI-D port below it, followed by HDMI and Display Port with a small vent below it.


The cooler is pretty easy to remove once you remove the 4x spring screws.


A generous amount of thermal paste is on the direct heatpipe as well as a small strip of the thermal pad for 2 of the memory chips.


Just like the reference version, this card requires a 6 pin PCIe connector to power up the card. The PCB has Asus’ Digi+ VRM, with the array of Asus’ Super Alloy chokes and capacitors. There are a total of 8x Samsung K46G20325FD-FC03 chips (4x on each side) on both sides of the PCB.


4x Samsung chips surround the Solid Cap that is soldered on the side of the PCB, just behind the core.
