GIGABYTE GTX 1660 SUPER 6GB

The GIGABYTE GV-N166SD6-6G is a GeForce GTX 1660 SUPER graphics card built for 1080p gaming and multi-monitor productivity. It uses the NVIDIA Turing architecture with 1408 CUDA cores and a 1785 MHz core clock. Six GB of GDDR6 memory on a 192-bit bus provide 14000 MHz effective bandwidth. The card fits a standard ATX form factor at 226 mm length.

WINDFORCE 2X cooling under load

The WINDFORCE 2X cooler uses two 90 mm alternate-spinning fans and a protection back plate to manage heat during extended sessions. This layout moves air efficiently across the heatsink while the card draws power through a single 8-pin connector. A 450 W power supply is recommended to sustain the 1785 MHz boost clock without throttling during long gaming or rendering workloads.

PCI Express 3.0 x16 interface limits

The card connects via PCI Express 3.0 x16, capping theoretical bandwidth at the Gen 3.0 ceiling rather than newer Gen 4.0 or 5.0 speeds. Display outputs include one HDMI 2.0b and three DisplayPort 1.4 ports, supporting up to four monitors at 7680 x 4320 resolution at 60 Hz. DirectX 12 and OpenGL 4.6 provide the API foundation for current titles and creative applications.

Questions about this item

How loud and hot does the WINDFORCE 2X cooler run during all-day use?

The WINDFORCE 2X cooler uses two 90 mm alternate-spinning fans and a back plate to dissipate heat from the 1408 CUDA core GPU, targeting quiet operation under sustained load.

What power connector and PSU capacity are required to run this card?

The card draws power through a single 8-Pin connector and the manufacturer recommends a 450W power supply for stable operation.

Will the PCI Express 3.0 x16 interface work with my older PCIe 2.0 motherboard slot?

Yes, the PCI Express 3.0 x16 interface is backward compatible with PCIe 2.0 slots, though bandwidth will be limited to the older standard's speed.
