ROG Strix RTX 3070 Ti 8GB GDDR6X

This refurbished ASUS graphics card targets enthusiasts who want high frame rates at 1440p and entry-level 4K gaming. The NVIDIA Ampere GPU delivers 6144 CUDA cores and a 256-bit memory interface for strong rasterisation and ray-tracing performance. A PCI Express 4.0 x16 connection ensures full bandwidth on modern platforms.

Triple-fan cooler under sustained load

Three axial fans move air across a large heatsink so the GPU can hold its 1875 MHz OC boost clock or 1845 MHz gaming clock during extended sessions. The 290W thermal design power is managed by a 3 x 8-pin power connector layout fed from a 750W supply. Temperatures stay controlled without throttling in long workloads.

8GB 256-bit GDDR6X frame buffer

The 8GB capacity paired with 19 Gbps memory speed decides if this card fits your texture-heavy titles or multi-monitor setup. Four display outputs — two HDMI 2.1 and three DisplayPort 1.4a — drive up to 7680 x 4320 resolution across four screens. DirectX 12 Ultimate and OpenGL 4.6 support complete the feature set.

Questions about this item

How loud and hot does the triple-fan cooler get when the card draws its 290 W TDP all day?

The triple-fan design is built to dissipate the 290 W thermal design power, so sustained loads stay within the cooler’s capacity without excessive noise.

What power supply and connectors must my system already have for this 750 W-recommended card?

A 750 W PSU with three 8-pin PCIe power connectors is required to feed the 290 W TDP and factory overclock.

Will the PCI Express 4.0 x16 interface run at full speed on my older PCIe 3.0 motherboard?

The card is backward compatible; it will operate at PCIe 3.0 x16 speeds on a 3.0 board with negligible performance loss.
