ASUS NUC 15 Pro vs Pro+: Same Small Box, Very Different Ambitions?
Same ports, different ambitions. The ASUS NUC 15 Pro+ keeps the NUC 15 Pro's connections but adds the 65W Core Ultra 9 285H, a 150W adapter, a silver aluminium chassis and a claimed 1.2x reduction in noise. The ASUS NUC 15 Pro tops out at Core Ultra 7 at 40W, comes in black Slim or Tall versions, and suits most office work. ASUS rates the Pro+ at up to 99 platform TOPS against 97 for the Pro, so AI is not the reason to choose between them; sustained CPU performance and finish are. At SourceIT the NUC 15 Pro+ Slim Ultra 9 285H barebone is S$1,022.05, against S$821.72 for the NUC 15 Pro Slim Ultra 7 255H barebone, a S$200.33 difference (listed 3 Nov 2026).

Does the extra power make a real difference?
For long, heavy CPU jobs, yes; for office work, rarely. The Ultra 9 285H in the Pro+ can draw much more power: techtest.org measured about 70W sustained CPU load and up to 130W at full load, while the system idled at about 4.7W. That headroom helps with code compiles, large spreadsheets, photo exports and virtual machines. Reviewers also note its limits. Notebookcheck found the Pro+ "cannot maintain its full performance in the long term" in a looped Cinebench test, though it stayed fairly steady, and called it clearly audible under load until the BIOS fan curve was adjusted. A NUC 15 Pro Tall with the Ultra 7 255H was described by Basic Tutorials as barely noticeable in office use but "quite loud", about 45 dB, under demanding tasks.
The Pro+ is the NUC 15 Pro with a bigger engine and a nicer jacket. Pay for it if your work keeps the engine running.
Who should buy which?
- NUC 15 Pro for office desks, reception, meeting rooms and signage, where the CPU spends most of its time waiting. It is also the only one of the two with a Tall chassis option; see ASUS NUC Slim vs Tall.
- NUC 15 Pro+ for developers, analysts and engineers running sustained CPU workloads, or anywhere the aluminium finish is visible, such as executive desks.
- Neither if you need the Copilot+ features or a stronger AI GPU: both have a 13 TOPS NPU. Look at the NUC 16 Pro instead; see NUC 16 Pro vs NUC 15 Pro.
One memory tip applies to both: Intel says Arc graphics on these chips need at least 16GB in a dual-channel setup, so install two memory modules rather than one. Our ASUS NUC Buyer's Guide compares the wider family.
