Compatibility calculation

Check	Available	Required	Result	Data confidence
GPU length	455.7mm case limit	357.6mm GPU	PASS · 98.1mm	Manufacturer verified
Height + power cable	200mm case envelope	185.3mm (149.3+36)	PASS · 14.7mm	FitMyPC estimate
GPU thickness	90mm case envelope	76mm GPU	PASS · 14mm	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.
