ASUS ROG Strix RTX 3080 10GB

The ASUS ROG Strix GeForce RTX 3080 delivers 10GB of GDDR6X memory across a 320-bit interface for 4K gaming and creative workloads. A PCI Express 4.0 connection feeds 8704 CUDA cores with a 1440 MHz base clock and a 1905 MHz gaming boost. Three DisplayPort 1.4a and two HDMI 2.1 outputs drive up to four displays at 7680 x 4320 resolution.

Sustained load performance

Under continuous load the card runs at its gaming boost of 1905 MHz while memory operates at 19 Gbps effective. The 320-bit bus keeps bandwidth steady for extended ray-tracing or compute sessions without throttling to the 1440 MHz base. Three 8-pin connectors supply the 750W thermal design power so clocks remain stable across long renders.

Thermals noise and power

A triple-fan cooler dissipates the 750W TDP while a recommended 850W PSU provides headroom for transient spikes. The HDCP 2.3 compliant outputs and VR-ready certification mean typical gaming or VR sessions stay within the cooling capacity without excessive acoustic output. Power draw scales with the 1935 MHz OC mode only when manually enabled.

Questions about this item

How much heat and power does the RTX 3080 produce when it runs all day under load?

The card has a thermal design power of 750W and uses three 8-pin power connectors; ASUS recommends an 850W power supply to keep it stable during extended sessions.

What power supply and connectors must I already own before installing this ROG Strix card?

You need a power supply rated for at least 850W with three available 8-pin PCIe power cables to feed the 750W TDP.

Will this PCI Express 4.0 graphics card work properly in my older motherboard that only has PCI Express 3.0 slots?

Yes, the PCI Express 4.0 interface is backward compatible with PCI Express 3.0 slots, though bandwidth will be limited to the 3.0 specification.
