ZOTAC GTX 1660 SUPER 6GB GDDR6

The ZOTAC GeForce GTX 1660 SUPER is a PCI Express 3.0 graphics card built on NVIDIA Turing architecture. It delivers 1408 CUDA cores and 6GB of GDDR6 memory across a 192-bit interface. The dual-slot design measures 173 mm in length and fits 99% of systems. It targets 1080p gaming and VR-ready workloads.

Sustained load thermal behaviour

A dual-fan cooler manages the 125W thermal design power under continuous gaming sessions. The compact 6.83-inch form factor maintains airflow inside tight chassis without a bulky heatsink. An 8-pin power connector feeds the GPU at its 1785 MHz boost clock. A 450W power supply is the recommended minimum for stable operation.

6GB 192-bit GDDR6 frame buffer

The 6GB GDDR6 frame buffer running at 14 Gbps sets the practical ceiling for texture quality and resolution. DisplayPort 1.4 drives up to 8K at 60 Hz while HDMI 2.0b handles 4K at 60 Hz. Four simultaneous monitors are supported across three DisplayPort and one HDMI output. DirectX 12 and OpenGL 4.6 cover modern API requirements.

Questions about this item

How much heat does the 125W TDP card put out when it runs all day?

The thermal design power is 125W, so sustained loads will draw roughly that much energy and release it as heat inside the case.

Which power connector must my supply already have for this 1660 SUPER?

An 8-pin PCIe power connector is required, and the maker recommends a 450W or larger unit.

Will the 173 mm length fit alongside the drive cage in my older chassis?

At 173 mm long the dual-slot board fits in 99% of systems, leaving room for most legacy drive bays.
