High-capacity RTX 3090 for demanding creative

The MSI GeForce RTX 3090 SUPRIM X 24G delivers 24GB of GDDR6X memory across a 384bit interface for professional rendering and high-resolution gaming. A core clock of 19500MHz drives the NVIDIA chipset through a PCI Express 4.0 16X connection. It targets users who need maximum frame-buffer capacity for 7680×4320 output.

Sustained load behaviour with triple 8-pin power

Three 8pin connectors supply the power headroom required for extended compute or gaming sessions without throttling. The 384bit memory bus maintains bandwidth consistency when textures and assets fill the 24GB buffer. This configuration supports stable throughput during long renders or continuous high-refresh gameplay.

Used-condition build with no accessories included

The card is rated 90% to 80% new and ships without original packaging or additional accessories. Each unit undergoes a 100% inspection before dispatch to verify functional integrity. Buyers should confirm physical clearance and power-supply compatibility before purchase.

Questions about this item

Will the triple 8-pin power connector fit my power supply?

The card needs three 8-pin PCIe power cables. Check that your PSU has enough 8-pin outputs and sufficient total wattage for a 3090-class GPU.

Does the 384-bit GDDR6X memory help with 4K and 8K workloads?

The 24 GB frame buffer running at 19500 MHz across a 384-bit bus delivers the bandwidth needed for 7680×4320 output and heavy texture loads.

How much case length should I allow for this SUPRIM X model?

SUPRIM X coolers are typically over 320 mm long. Measure from the rear bracket to the nearest drive cage or fan mount before ordering.
