ASUS TUF RTX 3070 8GB Gaming GPU

The ASUS TUF GeForce RTX 3070 is a refurbished graphics card built on the NVIDIA Ampere architecture. It delivers 5888 CUDA cores and 8GB of GDDR6 memory across a 256-bit bus. The card connects via PCI Express 4.0 and draws power through two 8-pin connectors. A triple-fan cooler manages thermals under load.

Best for 1440p gaming and VR rigs

This card suits builders targeting high-refresh 1440p play or entry-level 4K with a 750W power supply. It supports four simultaneous displays over two HDMI 2.1 and three DisplayPort 1.4a outputs. Systems limited to PCIe 3.0 or PSUs below 750W should consider a lower-tier model instead.

8GB GDDR6 frame buffer decides fit

The 8GB GDDR6 frame buffer is the single spec that determines whether this GPU matches your workload. It caps texture pool size for modern titles at 1440p ultra or 4K medium settings. If your workflow needs more video memory for 4K high textures or heavy compute, look at a card with a larger buffer.

Questions about this item

What case clearance does the triple-fan cooler on the TUF-RTX3070-O8G-GAMING require?

The card uses a triple-fan design; measure your chassis length and height against the cooler to confirm it will fit before ordering.

How do I connect power to the two 8-Pin connectors on this RTX 3070?

Plug two separate 8-Pin PCIe cables from the power supply into the card; avoid using a single daisy-chained cable so each connector gets full current.

When should I replace the thermal paste on the GeForce RTX 3070 GPU?

Re-paste if core temperatures rise noticeably above stock levels after cleaning the heatsink and verifying fan operation.
