Questions

Does the Gigabyte GeForce RTX 5090 Gaming OC 32G fit in the Jonsbo Z20?
Yes. The Gigabyte GeForce RTX 5090 Gaming OC 32G fits the Jonsbo Z20 with 21 mm of length to spare. Length 342 of 363 mm, height 152 mm (no published limit), thickness 3.44 slots (no published limit).
Is anything not checked?
Jonsbo doesn't publish a height or thickness limit for the Z20, so those aren't checked.
Where do these numbers come from?
Jonsbo's published spec; 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.
