On psu wattage the spread is 19%, AOOSTAR AG03 800 W against Sonnet eGFX Breakaway Box 650 650 W, so AOOSTAR AG03 takes it. They differ on connection standard too, Thunderbolt 5 + OCuLink on the AOOSTAR AG03 versus Thunderbolt 3 on the Sonnet eGFX Breakaway Box 650. They differ on gpu compatibility too, RTX 4060 up to RTX 4090 on the AOOSTAR AG03 versus GTX 10-series through RTX 30-series and equivalent AMD cards,... on the Sonnet eGFX Breakaway Box 650.

Who each one is for
Take the AOOSTAR AG03 for buyers wanting maximum host-device flexibility across both Thunderbolt 5 and OCuLink-equipped systems. It is equally the pick for anyone wanting flagship-tier GPU support (up to RTX 4090) without paying flagship-only pricing. It is not the one for buyers with a single, specific host connection type already decided, a single-standard enclosure specifically optimized for that one standard may be simpler. The Sonnet eGFX Breakaway Box 650 is the one to take for RTX 3060/3070-class double-wide card builds on Thunderbolt 3. It also earns its place with Mac users wanting official Apple eGPU certification on a mid-tier budget. It is the wrong buy for RTX 3080 Ti/3090 or RTX 40-series cards that want more PSU headroom. Our rating of the AOOSTAR AG03 (10/10): best overall, dual Thunderbolt 5/OCuLink connectivity and an 800W PSU handling up to an RTX 4090, all for under $500. Our rating of the Sonnet eGFX Breakaway Box 650 (7/10): the right-sized Sonnet box for mid-range Thunderbolt 3 cards, officially Mac-certified.
