EVA Edition RTX 3090 24GB

This ASUS ROG Strix card is a refurbished GeForce RTX 3090 with 24GB GDDR6X memory on a 384-bit interface. It targets creators and enthusiasts who need high VRAM capacity for 8K workflows or heavy rendering. The Ampere GPU runs at 1860 MHz in Gaming Mode and 1890 MHz in OC Mode with 10496 CUDA cores.

Compatibility check PCIe 4.0 and 850W PSU

Verify that your motherboard provides a PCI Express 4.0 slot and that your chassis can fit a 2.9-slot triple-fan cooler. The card draws 350W TDP and requires three 8-pin power connectors. HDCP 2.3 and HDMI 2.1 outputs support 7680 x 4320 resolution across up to four displays.

Sustained load 350W triple-fan cooling

Under continuous load the 350W thermal design is managed by the Axial-tech triple-fan cooler and Super Alloy Power II components. The 2.9-slot heatsink dissipates heat steadily rather than relying on short boost windows. GPU Tweak software lets you balance clock speed, fan curve and power target for stable long-duration performance.

Questions about this item

Will my case accommodate the 2.9-slot thickness and triple-fan cooler of this RTX 3090?

The card occupies 2.9 slots and uses a triple-fan cooler. Measure the clearance from your motherboard PCIe slot to the side panel and check the maximum GPU length your case supports.

Does my power supply need three separate 8-pin cables or can I use daisy-chained connectors?

The board draws up to 350 W and requires three 8-pin PCIe connectors. Use one dedicated cable per connector from the PSU; avoid daisy-chained pigtails to keep voltage stable.

What monitor cables do I need to run 7680 x 4320 at the highest refresh rate?

For 7680 x 4320 use the HDMI 2.1 ports with Ultra High Speed HDMI cables, or the DisplayPort 1.4a ports with certified DP 1.4 cables that support the required bandwidth.
