Compatibility calculation

Check	Available	Required	Result	Data confidence
GPU length	415mm case limit	330.8mm GPU	PASS · 84.2mm	Manufacturer verified
Height + power cable	165mm case envelope	164.5mm (128.5+36)	PASS · 0.5mm	FitMyPC estimate
GPU thickness	70mm case envelope	65.7mm GPU	PASS · 4.3mm	FitMyPC estimate

Some case clearance fields used by this result are estimates, so treat a pass as a likely fit rather than a manufacturer guarantee. A front radiator can reduce available GPU length and change this answer.
