24GB GDDR6X graphics card

The MSI RTX 4090 VENTUS 3X E 24G OC is a refurbished GPU built on the NVIDIA GeForce RTX 40 Series architecture. It delivers 16384 CUDA cores and 24GB of memory across a 384-Bit interface for high-resolution rendering and compute workloads. The PCI Express 4.0 connection suits modern workstations and enthusiast desktops.

Triple-fan cooling under sustained load

Three fans move air across a large heatsink to manage the 450W thermal design power during extended sessions. The silver shroud directs airflow toward the rear of the chassis for consistent exhaust. Stable clocks are maintained when the power connector supplies clean current.

337mm length and 16-pin power check

Verify that your case clears a 337mm card and that the power supply includes a native 16-pin connector or a certified adapter. The board occupies multiple slots, so confirm motherboard spacing and rear bracket clearance. A 450W TDP demands adequate headroom on the 12V rail.

Questions about this item

How much heat does the 450W TDP triple-fan cooler need to move during sustained loads?

The card is rated at 450W thermal design power and uses a triple-fan cooler to dissipate that heat under continuous operation.

What power connector must my PSU provide for the single 16-pin input?

Your power supply needs to deliver one 16-pin connector to feed the 450W board power requirement.

Will the 337 mm length fit alongside my existing PCIe 4.0 motherboard and case clearance?

The board measures 337 mm long and plugs into a PCIe 4.0 slot, so verify your case allows that length next to other installed cards.
