Will it fit

Will that graphics card fit in that case?

Start from the case you have or the card you want. We check every card’s length, height and thickness against the case maker’s published limits and show how much room is left.

Which case?

Every graphics card in the A4-H2O

  • 1 of 4 RTX 5090 cards fits the Lian Li A4-H2O. The nearest miss, the Gigabyte GeForce RTX 5090 Gaming OC 32G, is 20 mm too long and 0.44 slots too thick.

    Fits

    Yes. The NVIDIA GeForce RTX 5090 Founders Edition fits the Lian Li A4-H2O with 18 mm of length to spare.

    The full answer, with sources

By case

Every card against every case.

By card

Each card’s size, and every case it fits.

How we check

Published numbers, named sources.

  • Case limits are the case maker’s published spec, with a link to it on every page, unless the page says we measured the case ourselves. Where a maker publishes no height or thickness limit, we say so rather than guess.
  • Card sizes come from the card maker’s spec page; where a maker gives sizes with and without the bracket, we use the larger.
  • Some cases trade room: the Terra’s spine and the Era 2’s central wall give the card millimetres the CPU cooler loses. We pick the position that leaves the cooler the most room.
  • “Tight” means it fits on paper with less than 10 mm of length, 5 mm of height or 3 mm of thickness left, or only by giving something up. Power connectors and cables need room too, so measure before you buy a tight one.
  • 25 cases and 41 current RTX 50 and RX 9000 cards from the main board partners, checked October 2026.

Based on published dimensions, not a guarantee. Check cable, cooler and connector clearance before you buy.
