Overview

Built TUF
The ASUS TUF Gaming GeForce GTX 1660 Ti EVO stacks durability, compatibility, and performance to bring reliable 3D horsepower to the TUF Gaming ecosystem. Stand-out features include Auto-Extreme Technology, TUF compatibility testing, and two fans with space-grade lubricant and IP5X dust resistance.

IP5X Dust Resistance
Dust is enemy number one for fans. It’s easy to clean the blades, but taking the fan apart to remove dust that has made its way inside is not a simple task. Passing the IP5X certification means the housing is safe from nasty particulates, so you'll never need that deep clean.

Space−grade Lubricant
Infused with a durable lubricant often found in aerospace applications, these sleeve bearings deliver a quieter acoustic profile than dual ball bearing designs and match their durability.

DirectCU II
Copper heatpipes make direct contact with the die for improved thermal transfer.

Auto-Extreme Technology
Auto-Extreme Technology is an automated manufacturing process that sets new standards in the industry by allowing all soldering to be completed in a single pass. This reduces thermal strain on components and avoids the use of harsh cleaning chemicals, resulting in less environmental impact, lower manufacturing power consumption, and a more reliable product overall.

Protective Backplate
The PCB is reinforced by a backplate that adds structural rigidity, helping to prevent PCB flex and protect components and trace pathways from damage.

Compact Design
The TUF Gaming GeForce GTX 1660 Ti EVO packs potent rendering power into a compact frame that maximizes compatibility with the latest chassis.

Stainless Steel Bracket
The mounting bracket of the TUF Gaming GeForce GTX 1660 Ti EVO has been beefed up with 304 Stainless Steel that is harder and more resistant to corrosion.

GPU Tweak II
The ASUS GPU Tweak II utility takes graphics card tuning to the next level. It allows you to tweak critical parameters including GPU core clocks, memory frequency, and voltage settings, with the option to monitor everything in real-time through a customizable on-screen display. Advanced fan control is also included along with many more features to help you get the most out of your graphics card.

We also carry out reliability trials that include a 144-hour stability test and a series of 3DMark benchmarking runs to ensure the card performs well when pushed to the limits.

TUF Compatibility Testing
ASUS TUF Gaming products and TUF Gaming Alliance products from our partners are subjected to extra tests to ensure compatibility. The TUF Gaming GeForce GTX 1660 Ti EVO has been thoroughly tested with TUF Gaming motherboards to ensure a seamless plug-and-play experience. In addition to streamlining the building process, aesthetic harmony is a serious benefit for those who value a uniform style.
