ASUS TUF RTX 3080 12GB GDDR6X

The ASUS TUF Gaming GeForce RTX 3080 OC Edition is a graphics card built on the NVIDIA Ampere architecture. It delivers 12GB of GDDR6X memory across a 384-Bit interface with 8960 CUDA cores. The card connects via PCI Express 4.0 and includes two HDMI 2.1 and three DisplayPort 1.4a outputs.

Suits 4K gaming and VR builds needing 12GB VRAM

This card fits users targeting 7680 x 4320 resolution on up to four displays with HDCP 2.3 support. The dual 8-pin power connectors and 850W recommended PSU requirement mean systems with lower wattage units or only a single 8-pin cable should consider other options.

12GB 384-Bit GDDR6X decides fit for

The 12GB frame buffer paired with a 384-Bit bus and 19 Gbps effective clock determines whether the card handles your texture-heavy 4K titles or multi-monitor VR setup. If your workload needs more memory bandwidth or a different VRAM capacity, look at alternative models.

Questions about this item

What case clearance and power supply do I need for the ASUS TUF-RTX3080-O12G-GAMING?

The card uses a triple-fan cooler and needs two 8-pin power connectors; ASUS recommends an 850W PSU.

How do I install the card and which step is often missed?

Insert the card into a PCI Express 4.0 slot, secure the bracket screw, then connect both 8-pin power cables — missing the second connector is the common error.

What maintenance will the cooling system need later?

The dual ball fan bearings are rated for long life; periodic dust removal from the triple-fan heatsink keeps temperatures stable.
