ASUS KO GeForce RTX 3070 8GB
This graphics card uses the NVIDIA GeForce RTX 3070 GPU with 5888 CUDA cores and 8GB of GDDR6 memory on a 256-bit interface. It connects via PCI Express 4.0 and supports a maximum resolution of 7680 x 4320 across four displays. The dual-fan cooler handles thermal output in a 2.7-slot form factor.
Sustained load behaviour with dual-fan cooling
Under continuous workloads the card operates at a boost clock of 1815 MHz in Gaming Mode and 1845 MHz in OC Mode, with memory running at 14 Gbps. The double-fan cooler is designed to maintain these frequencies over extended periods rather than short bursts. A 750W power supply is recommended to feed the two 8-pin connectors reliably.
Build quality and daily connectivity
The board measures 275 mm in length and occupies 2.7 slots, so case clearance should be checked before installation. Outputs include two HDMI 2.1 ports and three DisplayPort 1.4a connectors for multi-monitor setups. HDCP 2.3 support ensures compatibility with protected content on modern displays.

Questions sur cet article
How much power does the RTX 3070 draw and what PSU is recommended for all-day use?
The card uses two 8-pin connectors and the manufacturer recommends a 750W power supply for stable operation.
My motherboard only has PCI Express 3.0 slots; will this KO series card still work?
Yes, the PCI Express 4.0 interface is backward compatible with 3.0 slots, so the card will function normally.
Can I keep using my older 1080p monitors that only have HDMI 1.4 inputs?
The two HDMI 2.1 ports and three DisplayPort 1.4a outputs will drive older 1080p displays without any issues.
