Refurbished TUF Gaming RTX 3080 Ti for 4K rigs

This refurbished ASUS TUF Gaming GeForce RTX 3080 Ti delivers 12GB of GDDR6X memory on a 384-bit bus with 10240 CUDA cores. The Ampere GPU runs at a 1755 MHz gaming boost clock and a 1785 MHz OC boost clock over a PCI Express 4.0 interface. It suits enthusiasts building a high-refresh 4K gaming PC or a GPU-accelerated workstation.

Step up from 10GB cards when VRAM limits appear

Moving from a 10GB Ampere card such as the RTX 3080 adds 2GB more frame buffer and a wider 384-bit interface running at 19 Gbps. The jump matters when 4K textures, heavy mod lists or multi-monitor workloads push past 10GB. DirectX 12 Ultimate and OpenGL 4.6 support carry over unchanged.

Verify 850W PSU, dual 8-pin cables and case length

The board draws power through two 8-pin connectors and ASUS recommends an 850W supply. Outputs include two HDMI 2.1 and three DisplayPort 1.4a ports for up to four displays at 7680 x 4320. Confirm your chassis fits a triple-fan cooler and that no SLI bridge is required.

Questions about this item

What case clearance and power supply capacity are required for the triple-fan RTX 3080 Ti with its dual 8-pin connectors?

The card uses a triple-fan cooler and draws power through two 8-pin connectors; the manufacturer recommends an 850 W power supply and enough length clearance for a three-fan design.

How do I connect the two 8-pin power cables correctly so the 1785 MHz OC boost clock is stable?

Plug two separate 8-pin cables from the power supply into the card — do not use a single daisy-chained cable — then seat the card firmly in the PCI Express 4.0 slot and secure the bracket screw.

When should I plan to replace the thermal paste or fans on this 10240-core Ampere GPU?

Thermal paste typically lasts several years; replace it if GPU temperatures rise noticeably under load. The three fans are rated for long life, but swap any that develop noise or vibration.
