MSI GeForce RTX 5080 16G VENTUS 3X OC
A high-power RTX card with the same published memory capacity as several less costly alternatives.
Buy the RTX 5080 VENTUS 3X OC for demonstrated processing needs, not because its name implies more memory. It has 16 GB, like the 5070 Ti in this catalog. Compare actual application performance and the cost of supporting cooling and power before choosing.
Consider it when
- Demanding graphics or production work with evidence that this GPU improves the target task.
- A build with room for the exact 303 mm card and appropriate 16-pin power delivery.
Look again when
- A project limited primarily by VRAM capacity rather than GPU processing speed.
THE SPACE IT NEEDS
Make room for the whole card
- Card length
- 303mm
- Card height
- 121mm
- Card thickness
- 49mm
Compare length with the space left after front fans, radiators and drive cages. Card thickness and power-cable clearance are separate checks.

The checks that can change your choice
Same size does not mean same heat load
The catalog 5070 Ti and this 5080 share 303 × 121 × 49 mm dimensions, but this card’s published power is 360 W. Reassess case airflow and noise rather than copying the other configuration.
Check the full power path
MSI recommends an 850 W PSU and ATX 3.1. Confirm the exact PSU cable or supplied adapter, complete insertion and panel clearance using the manufacturers’ instructions before running a sustained workload.
Published specifications
16 GB GDDR7; 303 × 121 × 49 mm; 360 W card power; 850 W recommended PSU; 1 × 16-pin; ATX 3.1 PSU recommended.
