TUF Gaming GTX 1660 SUPER 6GB

The ASUS TUF Gaming GeForce GTX 1660 SUPER is a mid-range graphics card built for 1080p gaming. It features 1408 CUDA cores and 6GB of GDDR6 memory across a 192-bit interface. The PCI Express 3.0 x16 interface connects to a standard motherboard slot. A factory overclock raises the boost clock to 1845 MHz in OC mode for extra headroom.

Upgrade from GTX 1060 or original GTX 1660

This card replaces an older GTX 1060 6GB or the first GTX 1660 with noticeably higher frame rates. The faster GDDR6 memory and higher clocks deliver up to 1.5X performance over the GTX 1060 6GB. The jump is worth it when your current GPU struggles to hit 60 fps in modern titles at high settings. An 8-pin power connector and a 450W power supply are required for stable operation.

PCI Express 3.0 x16 bandwidth limits

The PCI Express 3.0 x16 link provides ample bandwidth for this performance tier. Bottlenecks only appear if the card is installed in a secondary slot wired at x8 or x4 speeds. The 192-bit memory bus and 14002 MHz effective clock feed the GPU without saturating the system bus. Three display outputs support up to 7680 x 4320 resolution across multiple monitors.

Questions about this item

Does the PCI Express 3.0 x16 slot and 125 W TDP require a 450 W power supply and an 8-Pin connector?

Yes, the card draws up to 125 W and needs one 8-Pin power connector; a 450 W PSU is the recommended minimum.

Which driver step is often missed when switching to the NVIDIA Turing GPU with 1408 CUDA cores?

After seating the card in the PCIe 3.0 x16 slot and attaching the 8-Pin connector, install the latest NVIDIA driver before launching games; skipping this leaves the 1408 CUDA cores running on the basic Microsoft driver.

How often should the dual-fan cooler be cleaned to keep the 125 W GPU at safe temperatures?

Remove dust from the two fans and heatsink fins every 6 to 12 months, or more often in dusty environments, to maintain airflow over the 125 W thermal design.
