TUF Gaming GeForce RTX 3070 Ti 8GB GDDR6X

The ASUS TUF Gaming GeForce RTX 3070 Ti OC Edition is a graphics card built for 1440p gaming and creative workloads. It uses the NVIDIA Ampere architecture with 6144 CUDA cores and 8GB of 256-bit GDDR6X memory running at 19 Gbps. Two factory profiles offer boost clocks of 1815 MHz in OC mode and 1785 MHz in Gaming mode.

PCI Express 4.0 x16 slot and PSU headroom

The card installs in a PCI Express 4.0 x16 slot and draws power through standard 8-pin connectors. Its dual-slot cooler leaves adjacent slots free for capture cards or extra storage controllers. Three DisplayPort 1.4a outputs and two HDMI ports drive up to four monitors at 7680 x 4320 resolution without adapters.

Axial-tech fans and vapor chamber under load

Axial-tech fans and a vapor-chamber base keep the GPU stable during extended sessions. The 3070 Ti core maintains its 1815 MHz OC boost or 1785 MHz Gaming boost without throttling, while GDDR6X memory stays cool at 19 Gbps. DirectX 12 Ultimate and OpenGL 4.6 support ensure consistent frame rates in long renders or marathon gaming.

Questions about this item

How high does the boost clock reach in OC mode before thermal limits throttle it?

The card is rated for an 1815 MHz boost clock in OC mode; sustained loads will hold that frequency until the GPU hits its thermal ceiling.

What noise and heat levels should I expect when the card runs at full load all day?

The triple-fan cooler keeps the 3070 Ti at its 1785 MHz gaming-mode boost during extended sessions; fan noise rises with temperature but stays within typical TUF acoustics.

Which power connectors must my PSU provide for this graphics card?

The board draws power through two 8-pin PCIe connectors; ensure your supply has both cables available before installation.
