Will it fit? Check your graphics card, cooler and case

Pick your case and your parts. The tool compares them with the clearances each maker publishes and tells you, in millimeters, whether they fit and how much room is left.

How it checks

Every clearance comes from the case maker's own spec page: maximum graphics card length, maximum CPU cooler height, radiator support and motherboard sizes.

Graphics card length is a spec of each specific card, not of the chip: two cards with the same GPU can differ by several centimeters depending on the brand. Check the exact model you are buying.

With less than 10 mm to spare for the card, or 5 mm for the cooler, the tool marks it as tight: it fits, but cables, front fans or the side panel can get in the way.

If a maker does not publish a measurement, the tool says so instead of guessing.
