Product identity
The ASUS TUF Gaming GeForce RTX 4090 OG OC Edition is a refurbished graphics card built for 4K gaming and heavy creative workloads. It ships with 24GB of GDDR6X memory on a 384-bit bus and a PCI Express 4.0 x16 interface. The GPU runs at a 2235 MHz core clock with a 2595 MHz boost clock in OC mode.
Sustained load behaviour
A 450 W thermal design power and a 16-pin power connector feed the 16384 CUDA cores under continuous load. The triple-fan cooler uses a reversed central fan and dual ball bearings to move air through a 3.2-slot heatsink. Military-grade capacitors rated for 20K hours at 105°C keep the power rail stable during long render or compute sessions.
Upgrade context
The card replaces earlier 24GB Ampere flagships and mid-range Ada models when 450 W TDP and 850 W PSU headroom are acceptable. The jump is worth it for workflows that need 21 Gbps memory bandwidth and DLSS 3 frame generation at 7680 x 4320 output.

Questions about this item
How much power does the TUF-RTX4090-O24G-OG-GAMING draw and what PSU is recommended for all-day use?
The card has a 450W thermal design power and ASUS recommends an 850W power supply for stable operation.
Which power connector must my PSU already provide for this graphics card?
It requires one 16-pin connector, so your power supply needs to include that cable.
Will the 3.2-slot width and 326 mm length fit alongside my existing ATX motherboard and case?
The card occupies 3.2 slots and measures 326 mm long, so verify your case clearance and motherboard spacing before installing.
