Questions

Does the PowerColor Hellhound Radeon RX 9070 XT fit in the NZXT H5 Flow?
Yes. The PowerColor Hellhound Radeon RX 9070 XT fits the NZXT H5 Flow with 70 mm of length to spare. Length 340 of 410 mm, height 142 mm (no published limit), thickness 2.5 slots (no published limit).
Is anything not checked?
NZXT doesn't publish a height or thickness limit for the H5 Flow, so those aren't checked.
Where do these numbers come from?
NZXT's published spec; card size from PowerColor'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.
