Liquid-cooled flagship for 4K creators

The MSI RTX 4090 SUPRIM LIQUID 24G is a PCI Express 4.0 graphics card built around the GeForce RTX 4090 GPU with 16384 CUDA cores and 24GB of 384-bit GDDR6X memory. It targets professionals and enthusiasts who need sustained compute throughput for rendering, simulation or high-refresh 4K gaming. A factory boost clock of 2595 MHz and 21 Gbps memory speed deliver the raw bandwidth those workloads demand.

Sustained load behaviour with liquid cooling

The integrated liquid cooler moves heat away from the GPU die continuously, allowing the card to hold its 2595 MHz boost clock through extended rendering or compute sessions rather than throttling after a short burst. The 450W thermal design power is fed by a single 16-pin connector, so power delivery remains stable when every CUDA core is active for hours. Frame pacing stays consistent because temperatures do not climb into the throttling zone.

Thermals noise and power in normal use

Under typical gaming or creative loads the liquid loop keeps the GPU well below its thermal limit, so the radiator fans can spin at low RPM and remain quiet. The 850W recommended PSU provides headroom for the 450W board power plus system overhead. HDMI 2.1a and three DisplayPort 1.4a outputs drive up to four displays at 7680 x 4320 resolution without requiring additional adapters.

Questions about this item

How much power does the 450 W thermal design draw from the 16-pin connector during all-day loads?

The card has a 450 W thermal design and uses a single 16-pin power connector; an 850 W power supply is recommended to sustain continuous operation.

What power supply and case clearance do I need before installing this 280 mm liquid-cooled card?

An 850 W PSU with a native 16-pin cable is required, and the chassis must accommodate a 280 mm radiator plus the 280 mm maximum GPU length.

Will the PCI Express 4.0 interface and 1.4a DisplayPort outputs work with my older PCIe 3.0 motherboard and 1.2 monitors?

The PCIe 4.0 x16 slot is backward compatible with PCIe 3.0 at reduced bandwidth, and the three DisplayPort 1.4a ports will drive DisplayPort 1.2 displays without issue.
