The Aoostar AG03 has officially stepped into the spotlight in China, showing off serious upgrades over its predecessor. This external GPU dock now features dual USB4 v2 (Thunderbolt 5) ports, unlocking up to 80 Gbps of bandwidth. That’s a major leap for those chasing faster data transfer and GPU flexibility.
Aoostar AG03 brings Thunderbolt 5 into play

The biggest upgrade? Those USB4 v2 ports. Compared to the original AG02’s USB4 slots, these newer ports more than double the bandwidth. One of the Thunderbolt 5 ports even supports up to 140 W power delivery, making it perfect for handheld gaming PCs that crave both performance and charging support. The second port delivers up to 27 W and can still handle external drives when needed.
Built-in 800 W PSU comes with a tradeoff
Aoostar didn’t just slap faster ports on the AG03, it added a built-in 800 W power supply. But here’s the catch: only 500 W goes to the desktop GPU. That’s a step down from the AG02’s 600 W GPU output, likely due to the upgraded ports drawing more juice. If you’re running a high-end graphics card, that change matters.
OCuLink support stays put
The OCuLink port makes a return, offering a direct PCIe connection for reduced latency. That said, the internal GPU slot remains PCIe 4.0 x4, unchanged from the last model. It’s still a standard x16 slot physically, but with limited lanes for data.
What’s missing from the Aoostar AG03?
Despite the upgrades, the AG03 still skips a few features some might expect at this level. Here’s a quick look at what’s still not here:
- No M.2 slot for SSD expansion
- No upgrade to PCIe interface bandwidth
- Still uses the same exterior design
So if you’re eyeing extra storage or visual flair, this dock won’t check those boxes.
Global launch of Aoostar AG03 still in question
Priced at CNY 1,499 (roughly $213), the Aoostar AG03 hits an appealing point for those needing a modern eGPU dock. But there’s no word yet on global availability. Until then, enthusiasts outside China will have to wait and hope the export plans match the hardware’s ambition.
