TUF Gaming GTX 1660 Ti OC Edition

The ASUS TUF Gaming GeForce GTX 1660 Ti EVO OC Edition is a refurbished graphics card built on NVIDIA Turing architecture with 1536 CUDA cores and 6GB GDDR6 memory. It connects via PCI Express 3.0 and offers boost clocks of 1845 MHz in OC mode and 1815 MHz in Gaming mode. The card targets 1080p gaming and streaming with a dedicated hardware encoder optimised for OBS.

120W sustained load with DirectCU II cooling

Under continuous load the board draws up to 120W and requires a 450W power supply with an 8-pin connector. DirectCU II copper heatpipes contact the GPU die directly while space-grade lubricant extends fan bearing life. A 144-hour validation program tests stability across current titles before the card ships.

2.3-slot fit with three display outputs

The 206 mm long card occupies 2.3 slots and fits most mid-tower cases without clearance issues. Outputs include two HDMI 2.0b ports, one DisplayPort 1.4a and one DVI-D connector supporting up to four monitors at 7680 x 4320 resolution. Auto-Extreme automated assembly reduces solder defects that can cause early failures.

Questions about this item

How loud and hot does the TUF GTX 1660 Ti run when gaming all day with its 120W TDP?

The 120W TDP is cooled by DirectCU II copper heatpipes touching the die and dual ball-bearing fans with space-grade lubricant for quieter sleeve-bearing operation. A 450W PSU and one 8-pin connector are recommended.

What power supply and case clearance do I already need for this 2.3-slot, 206 mm card?

A 450W PSU with an 8-pin PCIe connector is recommended. The card measures 206 mm long and occupies 2.3 slots, so verify your case has that length and width clearance.

Will the GTX 1660 Ti's HDMI 2.0b, DisplayPort 1.4a and DVI-D ports drive my older 1080p monitors alongside a new 4K display?

Yes. The three output types support up to four monitors simultaneously at a maximum digital resolution of 7680 x 4320, so mixed 1080p and 4K setups work without adapters.
