INNO3D is a brand we've grown to admire over the years because it has consistently created compact and powerful GeForce RTX graphics cards. A two-slot RTX 5080 is one recent example; another is a dual-fan RTX 5070 that could fit inside the tiniest PC gaming case. If you're after something small, compact, and with a clean, minimal design, then INNO3D X2 or X3 cards are worth looking into.

The new INNO3D GEFORCE RTX 5090 X3 White GPU in an ITX case playing DOOM: The Dark Ages.

At Computex 2025, INNO3D showed us its INNO3D GEFORCE RTX 5090 X3, in white, inside a compact ITX case. As a GeForce RTX 5090, it's still fairly big, as expected, but it was cool to see it fit inside an ITX case, keeping cool while playing DOOM: The Dark Ages at over 300+ FPS in 4K with max settings.

This is INNO3D's first White-colored GeForce RTX 5090, which the company notes is quickly becoming Asia's most popular color option for PC gaming components. We've lost count of the sheer number of white-colored PC gear we've seen this week at Computex 2025, so that remark makes a lot of sense.

With an open case (as seen in the pictures) and DOOM: The Dark Ages running nonstop at INNO3D's demo station, the GPU temperature hovered around 63 or 64 degrees, which is excellent for the 600W beast. With the cover on, the temperature did increase, but only to around 70 degrees, a decent result for a powerful ITX gaming rig, especially one with a GeForce RTX 5090.

The company told us that the INNO3D GEFORCE RTX 5090 X3 White on display was a prototype model. It looks great in all white with the little touches of metal running across the top of the GPU. There's no word on a release date other than it should arrive sometime later this year.
