ASUS Dual GTX 1660 Super 6GB graphics card

The ASUS Dual GTX 1660 Super 6GB graphics card targets 1080p gamers and content creators who need reliable frame rates without moving to a higher tier. It uses the NVIDIA Turing architecture with 1408 CUDA cores and a 192-bit GDDR6 memory interface. The card connects through a PCI Express 3.0 slot and draws power from a single 8-pin connector. A 450W power supply is recommended for stable operation.

Sustained load behaviour with OC and Gaming modes

Under sustained load the card runs at either the OC mode boost clock of 1860 MHz or the default Gaming mode boost clock of 1830 MHz, both well above the 1530 MHz base clock. The 6GB GDDR6 frame buffer operates at an effective 14002 MHz, feeding the 1408 CUDA cores through the 192-bit bus. This configuration keeps 1080p workloads consistent during extended sessions without throttling to the base frequency.

Thermals noise and power draw in normal use

The dual-fan cooler manages the 125W thermal design power while keeping acoustic output low during typical gaming. The 8-pin power connector supplies the board directly, and the 450W PSU recommendation provides headroom for the rest of the system. In normal use the card stays within its thermal envelope, allowing the fans to run at modest speeds and keeping noise at a background level.

Questions about this item

How loud and hot does the DUAL-GTX1660S-O6G-EVO run under continuous load with its double-fan cooler and 125W TDP?

The dual-fan design manages the 125W thermal design power effectively; temperatures and fan noise remain moderate during extended gaming or compute sessions.

What power supply and connector does the DUAL-GTX1660S-O6G-EVO require to operate?

A 450W power supply with one free 8-pin PCIe power connector is needed to meet the card's 125W TDP.

Will the DUAL-GTX1660S-O6G-EVO fit and run on a motherboard that only has PCI Express 3.0 slots?

Yes, the card uses a PCI Express 3.0 x16 interface so it works at full speed on any PCIe 3.0 or newer slot.
