SFF GPU Clearance Checker
Will that graphics card actually fit your small-form-factor case? Checks length, thickness, height and cable bend across every spine position.
Quick Summary · TL;DR
SFF fitment is three-dimensional: length, thickness (slots) and height all have to clear at once, and a rigid power connector adds bend-radius height on top. This checker iterates every spine position of the case and only passes a configuration where all axes fit — then tells you the matching CPU-cooler limit.
Why length alone isn’t enough
Most fitment guides only list a maximum GPU length, but in sandwich-layout cases the real limit is usually thickness. A 4-slot card may clear on length yet collide with the side panel, and a flush 12VHPWR plug can add roughly 18mm of bend-radius height that pushes a card over the edge. This tool models all of that, including the non-linear curvature penalty in cases like the Fractal Terra.
Always verify: case limits are manufacturer-stated, but graphics-card dimensions differ between AIB models. Confirm your exact card’s length, height and slot width before purchasing.
Frequently asked questions
Why does my GPU need extra clearance for the power cable?
Because a rigid 12VHPWR or 8-pin plug needs bend-radius room above the card; a flush 12VHPWR connector can add roughly 18mm to the effective height, which matters in a tight sandwich-layout case.
What is the most common reason a GPU won't fit an SFF case?
Thickness, not length. Many builders check the length limit but miss that a 3.5 or 4-slot cooler is too thick for the case's spine position, causing a collision against the side panel.
Are these clearance numbers exact for every card?
They use manufacturer-stated case limits, but graphics-card dimensions vary by AIB model, so always confirm the exact length, height and slot width of your specific card before buying.
