SUPRIM X 24G 24GB GDDR6X

The MSI GeForce RTX 3090 SUPRIM X 24G is a graphics card built around the NVIDIA GeForce RTX 3090 display chip with 24GB of GDDR6X memory on a 384-bit bus. It connects through a PCI Express Gen 4 interface and draws power through three 8-pin connectors with an 850W supply suggestion. The card measures 336 x 140 x 61 mm and weighs 1895g.

Extreme Performance 1875 MHz for creators

The Extreme Performance mode pushes the core to 1875 MHz via Dragon Center, while GAMING and SILENT modes run at 1860 MHz. This suits creators and enthusiasts who need sustained compute throughput for rendering or AI workloads. Users with smaller cases or modest power budgets should consider a less demanding model instead.

Triple 8-pin power and 19.5 Gbps memory

Under sustained load the three 8-pin power connectors feed the GPU while 19.5 Gbps GDDR6X memory maintains high bandwidth across the 384-bit bus. The custom PCB and heavy 1895g construction help dissipate heat during long sessions. Outputs include three DisplayPort 1.4a ports and one HDMI 2.1 port supporting 4K at 120Hz.

Questions about this item

What power supply wattage and connectors does the RTX 3090 SUPRIM X 24G require?

The card needs an 850W power supply and three 8-pin PCIe power connectors to operate.

Will the three DisplayPort 1.4a and one HDMI 2.1 ports work with my existing 4K 60Hz monitors?

Yes, both interfaces are backwards compatible so your current 4K 60Hz displays will function normally.

How can I confirm the GPU is hitting its 1875 MHz extreme performance clock after setup?

Open MSI Dragon Center and observe the core frequency reading under load; it should report 1875 MHz in Extreme Performance mode.
