ASUS DUAL-GTX1660S-O6G-EVO

Overview

The ASUS DUAL-GTX1660S-O6G-EVO is a dedicated graphics card designed to deliver strong gaming performance and reliable operation. Built on NVIDIA's Turing architecture, it features 1408 CUDA cores and a factory-tuned boost clock that reaches up to 1860 MHz in OC mode. With 6 GB of GDDR6 memory on a 192-bit interface, this card handles modern games smoothly at 1080p and 1440p resolutions, allowing for high texture settings and fluid frame rates.

It supports multiple display setups through one DisplayPort 1.4, one HDMI 2.0b, and one DVI-D output, enabling up to three monitors with a maximum resolution of 7680 × 4320 at 60 Hz. The cooling system uses dual Axial-tech fans and DirectCU II heatpipes to keep temperatures low and noise minimal, while the card fits comfortably in most mid-tower and compact cases with a single 8-pin power connector requirement.

Performance and reliability

The cooling system is designed to keep the GPU temperature low during intense gaming or rendering sessions, with fans that remain quiet during everyday use. The IP5X dust resistance extends the lifespan of the fans by preventing dust accumulation, which helps maintain consistent performance over time. This makes the card a dependable choice for gamers, streamers, and content creators who need stable graphics performance.

Ideal uses and environments

This graphics card works well in gaming setups focused on 1080p and 1440p resolutions, delivering smooth frame rates and detailed visuals. It also suits home office users and students who require GPU acceleration for creative applications like video editing and photo processing. Its moderate power requirements and compact size make it a strong option for mid-range builds and upgrades without needing a high-wattage power supply or large case.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
