Liquid-cooled RTX 3080 Ti for 4K gaming

The ROG STRIX LC pairs a GeForce RTX 3080 Ti GPU with a closed-loop liquid cooler, targeting enthusiasts who want 12 GB GDDR6X memory and 10240 CUDA cores for 4K gameplay and heavy compute tasks. It connects through a PCI Express 4.0 slot and draws up to 350 W, so an 850 W supply with three 8-pin connectors is required. The card supports DirectX 12 Ultimate and OpenGL 4.6 for modern APIs.

Hybrid cooling keeps clocks stable under load

A 240 mm radiator and pump assembly move heat away from the GPU die, allowing the boost clock to hold at 1695 MHz in OC mode or 1665 MHz in Gaming mode during extended sessions rather than throttling after a short burst. Memory runs at 19 Gbps across a 384-bit bus, sustaining bandwidth for large textures and frame buffers. The hybrid design also reduces acoustic output compared with air-only coolers at equivalent power.

Reinforced frame and modern display outputs

A metal backplate and shroud stiffen the PCB, protecting solder joints when the card is mounted vertically or transported. Two HDMI 2.1 ports and three DisplayPort 1.4a connectors drive up to four monitors at 7680 x 4320 resolution, covering high-refresh 4K panels and VR headsets without adapters. HDCP 2.3 compliance ensures protected content plays back correctly.

Questions about this item

How loud and hot does the ROG-STRIX-LC-RTX3080TI-12G-GAMING run during all-day loads?

The hybrid cooler keeps the GeForce RTX 3080 Ti within its 350W thermal design power, so sustained full-load operation stays inside the 850W PSU recommendation without excessive noise or heat buildup.

What power connectors and PSU capacity must I already have for this card to work?

You need three 8-pin PCIe power cables and a power supply rated for at least 850W to meet the card's 350W TDP and PCI Express 4.0 interface requirements.

Will the RTX 3080 Ti's PCI Express 4.0 interface slow down on my older PCIe 3.0 motherboard?

The card operates at PCI Express 4.0 speeds but remains fully compatible with PCIe 3.0 slots; bandwidth reduction is minimal for gaming at 7680 x 4320 resolution.
