Questions

Does the ASUS TUF Gaming GeForce RTX 5070 Ti OC fit in the Lian Li A3-mATX?
Yes. The ASUS TUF Gaming GeForce RTX 5070 Ti OC fits the Lian Li A3-mATX with 86 mm of length to spare. Length 329 of 415 mm, height 140 mm (no published limit), thickness 3.125 of 4 slots.
Is anything not checked?
Lian Li doesn't publish a height limit for the A3-mATX, so that isn't checked.
Where do these numbers come from?
Lian Li's published spec; card size from ASUS'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.

  • A 25 mm fan under the card limits it to 61 mm (3 slots); a bottom radiator with fans leaves no room for a card.
