Ready for 1080p gaming

The GIGABYTE GV-N166SGAMING-6GD is a GeForce GTX 1660 SUPER graphics card built for 1080p gaming. It uses the NVIDIA Turing architecture with 1408 CUDA cores and a 1785 MHz core clock. The 6GB GDDR6 frame buffer on a 192-bit bus runs at an effective 14000 MHz. The WINDFORCE 3X cooler with alternate spinning fans keeps temperatures in check.

Check power and space first

Your power supply must deliver at least 450W and provide an 8-pin connector for the 125W board. The card occupies two slots and measures 280 mm long, so verify case clearance before ordering. A PCI Express 3.0 x16 slot is required. Display outputs include one HDMI 2.0b and three DisplayPort 1.4 connectors for up to four monitors at 7680 x 4320 @ 60 Hz.

Steady clocks under load

The 125W thermal design power means the card draws a consistent amount of energy during extended sessions. The WINDFORCE 3X cooler with alternate spinning fans and a protective back plate helps maintain the 1785 MHz core clock without rapid throttling. GDDR6 memory at 14000 MHz sustains bandwidth for longer 1080p workloads. Expect stable frame pacing rather than short burst peaks.

Questions about this item

Does the box include a power cable or adapter for the 8-pin connector?

The card requires one 8-pin PCIe power connector from your power supply; no adapter or cable is included in the box.

Is the 6 GB GDDR6 frame buffer enough for 1440p gaming or should I look for a larger model?

With 6 GB on a 192-bit bus the card handles 1080p ultra and many 1440p titles at high settings; heavier 1440p workloads may need more memory.

What does the 1785 MHz core clock deliver in actual games once the card is installed?

The 1785 MHz boost clock drives the 1408 CUDA cores for solid 1080p performance in modern titles at high to ultra quality.
