Asus has officially taken the reins of Intel’s NUC series, and the Asus NUC 15 Pro+ is its first true flagship move. This compact system doesn’t just aim to be efficient it’s out to challenge full-sized desktops with cutting-edge hardware, strong connectivity, and external GPU support. In testing, it largely delivers though not without some noise.
Asus NUC 15 Pro+ targets serious users with serious specs

Under the hood, the NUC 15 Pro+ features an Intel Core Ultra 9 285H, a top-tier mobile chip built with chiplet design and integrated AI acceleration. This isn’t just about power efficiency it’s about enabling serious performance for creative workloads, 3D modeling, and even AI applications.
Asus pairs the CPU with DDR5 memory, fast PCIe 4.0 SSDs, and a strong I/O lineup, including:
- 2x Thunderbolt 4
- 2.5 Gbit LAN
- Multiple USB-A and USB-C ports
- HDMI and DisplayPort outputs
This makes it a viable solution for anyone needing workstation-class power in a device that could fit in a backpack.
eGPU compatibility turns this mini into a gaming beast
One of the most compelling features of the NUC 15 Pro+ is its seamless support for external GPUs. During testing, the system handled an NVIDIA RTX 4090 with ease making it an unexpected powerhouse for AAA gaming, 4K video editing, or AI acceleration. While the internal graphics are capable for basic tasks, the ability to scale up graphics externally makes this device incredibly flexible.
Quick upgrades but a cooling tradeoff
Asus has made upgrading straightforward. RAM and SSD access is fast and tool-free, which adds long-term value for power users who want to tweak performance or expand storage down the line.
The downside? Noise. Under sustained workloads, the cooling system ramps up audibly. The fan curve is adjustable in the BIOS, but even with tweaking, it’s hard to make the system fully quiet during heavy use.
At a glance: Asus NUC 15 Pro+ strengths and drawbacks
What works:
- High-end Intel Core Ultra 9 performance
- External GPU support via Thunderbolt 4
- Plenty of ports and fast networking
- Easy maintenance and upgrades
What doesn’t:
- Noticeable fan noise under load
- No dedicated GPU inside (relies on eGPU for heavy graphics tasks)
Small form factor, serious ambition
The Asus NUC 15 Pro+ doesn’t settle for being a basic office cube. It’s a modular, scalable, and surprisingly powerful mini PC that proves small systems can take on big jobs if you’re willing to pair them with the right gear.
For pros and enthusiasts alike, it’s a bold next step in what the NUC line can be. Just bring your own GPU and maybe a pair of headphones.
