Ready for 1080p gaming and multi-monitor setups

The GIGABYTE GV-N166TOC-6GD is a GeForce GTX 1660 Ti OC graphics card built on the NVIDIA Turing architecture with 1536 CUDA cores and 6GB GDDR6 memory on a 192-bit bus. A boost clock of 1800 MHz provides headroom above the reference 1770 MHz. It connects via PCI Express 3.0 x16 and drives up to four displays through one HDMI 2.0b and three DisplayPort 1.4 outputs at up to 7680x4320@60Hz.

WINDFORCE 2X cooling keeps clocks stable under load

The dual-fan WINDFORCE 2X cooler uses alternate spinning 90mm blades, a composite copper heat pipe with direct GPU contact, and 3D active fan control to reduce turbulence and maintain lower temperatures during extended sessions. This layout sustains the 1800 MHz core clock and 12000 MHz effective memory clock without the throttling typical of compact single-fan designs.

Compact plug-in card with protection back plate

The card measures 1.6 by 4 units in a standard plug-in form factor and includes a metal back plate that stiffens the PCB and shields components during handling. One HDMI 2.0b and three DisplayPort 1.4 connectors support mixed monitor fleets without adapters, while the two-slot bracket fits most mid-tower cases. AORUS Engine software provides intuitive clock, fan and RGB control for day-to-day tuning.

Questions about this item

How loud or hot does the WINDFORCE 2X cooler with alternate spinning 90mm fans run during all-day use?

The WINDFORCE 2X cooling system uses two 90mm unique blade fans with alternate spinning and a composite copper heat pipe that directly touches the GPU, plus 3D active fan functionality to dissipate heat effectively at lower temperatures.

What power connector and PSU capacity does the GV-N166TOC-6GD need to operate?

The card draws power through the PCI Express 3.0 x16 slot and requires an external power connector; ensure your power supply has the necessary PCIe power cable and sufficient wattage for the 1800 MHz core clock and 1536 CUDA cores.

Will this GTX 1660 Ti work in an older motherboard that only has PCIe 2.0 slots?

The GV-N166TOC-6GD uses a PCI Express 3.0 x16 interface which is backward compatible with PCIe 2.0 motherboards, though it will run at the lower 2.0 bandwidth while still delivering 6GB GDDR6 memory and 12000 MHz effective memory clock.
