- Does the Gigabyte GeForce RTX 5090 Gaming OC 32G fit in the Lian Li A4-H2O?
- No. The Gigabyte GeForce RTX 5090 Gaming OC 32G is 20 mm too long and 0.44 slots too thick for the Lian Li A4-H2O. Length 342 of 322 mm, height 152 mm (no published limit), thickness ≈3.44 of 3 slots.
- Is anything not checked?
- Lian Li doesn't publish a height limit for the A4-H2O, so that isn't checked until we measure the case ourselves.
- Where do these numbers come from?
- Lian Li's published spec, not yet measured by Respec; card size from Gigabyte's spec page. Checked October 2026. Makers measure differently and connectors add a few millimetres, so treat a tight result as a reason to measure.
