Compatibility calculation

Check	Available	Required	Result	Data confidence
GPU length	435mm case limit	360mm GPU	PASS · 75mm	Manufacturer verified
Height + power cable	205mm case envelope	186mm (150+36)	PASS · 19mm	FitMyPC estimate
GPU thickness	90mm case envelope	75mm GPU	PASS · 15mm	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.
