ASUS Refurbished

ASUS ROG-STRIX-GTX1660S-A GeForce GTX 1660 SUPER 6GB graphics card

SKU CH-Q2JD-Q19QP MPN ROG-STRIX-GTX1660S-A

Refurbished GeForce GTX 1660 SUPER with 6 GB GDDR6, 1408 CUDA cores and a 1845 MHz OC boost clock

  • Graphics processorGeForce GTX 1660 SUPER
  • Memory capacity6 GB
  • Interface typePCI Express 3.0 x16
  • CUDA core count1408
  • Highest resolution7680 × 4320
  • Boost frequencyOC Mode: 1845 MHz Gaming Mode (Default): 1815 MHz
  • 6 GB GDDR6 memory delivers fast frame rates in 1080p games
  • Boost clock reaches 1845 MHz in OC mode for extra headroom
  • 1408 CUDA cores handle parallel workloads in modern titles
  • Dual HDMI 2.0b and dual DisplayPort 1.4 drive up to four displays
  • 125 W TDP runs on a 450 W PSU with a single 8-pin connector

Advanced Edition Boost Clocks

The card ships with two factory profiles: OC mode at 1845 MHz and Gaming mode at 1815 MHz. Both sit above the 1530 MHz base clock. The 1408 CUDA cores and 6GB GDDR6 frame buffer run on a 192-bit bus at 14002 MHz effective. It targets 1080p gaming on a PCI Express 3.0 x16 slot.

Upgrade From GTX 1060 6GB

NVIDIA rates the GTX 1660 SUPER up to 1.5X faster than the GTX 1060 6GB and roughly 20% quicker than the original GTX 1660. The jump is worthwhile when you need higher frame rates at 1080p without moving to a higher power tier. A 450W PSU and a single 8-pin connector keep the platform requirements modest.

Sustained 125W Thermal Load

The 125W TDP is handled by a dual-fan cooler that maintains clocks during extended sessions. HDCP 2.2 and four display outputs — two HDMI 2.0b and two DisplayPort 1.4 — support multi-monitor setups up to 7680 x 4320. DirectX 12 and OpenGL 4.6 cover current API needs.

Questions about this item

Will the 125W TDP and 8-pin power connector fit my 450W PSU?

The card draws 125W and needs one 8-pin connector; ASUS recommends a 450W PSU for the whole system.

How do I seat the PCI Express 3.0 x16 interface without bending the bracket?

Align the gold fingers with the slot, press straight down until the retention clip clicks, then secure the rear bracket screw.

When should I replace the thermal paste on the GDDR6 memory and GPU?

Refresh paste if temperatures rise above normal after a few years or when you disassemble the cooler for cleaning.
