ASUS NUC 15 Pro (Core Ultra 7 255H, 32GB, 1TB): problems, parts and running costs
Checked: 2026-10-17
Summary
A 0.48L mini PC built around the 16-core Core Ultra 7 255H, with quad 4K display output and a tool-less chassis for RAM and storage upgrades. There are no widespread owner failure reports; the practical issues are spec-level, such as an NPU too weak for Microsoft Copilot+ PC and a single full-size SSD slot. No running costs beyond electricity are documented, and no street price was found to judge a buy against.
Common problems and fixes
- NPU too weak for Copilot+ PC — the Arrow Lake-H NPU inside the 255H is 11 TOPS, so the machine misses Microsoft Copilot+ PC minimum specifications; there is no workaround, it is a platform limit. [3]
- Intel vPro only on selected SKUs — vPro is not available on every configuration, so check the exact part number before buying if vPro matters. [1]
- Single full-size SSD slot — the second M.2 slot is a 22x42 Gen4 expansion point, not a second full-size SSD bay; adding a second 22x80 SSD requires a separate ASUS accessory. [1][2]
- No published dimensions or power figures — ASUS does not list exact H x W x D or wattage; Liliputing reports 117 x 112 x 54 mm (tall) or 117 x 112 x 37 mm (slim). [3]
- Same chassis as the NUC 14 Pro — the physical design is unchanged, so the changes are internal (Arrow Lake vs Meteor Lake); any older-model chassis quirks may carry over. [3]
Parts and consumables
- DDR5-6400 SODIMM memory — up to 96GB across two slots at 1.1V; the tool-less chassis makes upgrades screwdriver-free. [2]
- M.2 22x80 PCIe Gen5 NVMe SSD — the main storage slot; ASUS uses name-brand components from Samsung, SK Hynix and Micron, and its Parts Shop (partshop.asus.com) stocks replacement parts. [2][3]
Yearly running cost
Not enough data. No consumable, filter or subscription is reported and no power-consumption figure was published, so a yearly electricity figure cannot be computed. The ASUS Parts Shop stocks replacement parts, but no part prices were found.
When it is a good buy
No street price was found: ASUS’s where-to-buy page lists Adorama, Newegg, CDW, B&H Photo Video, AntOnline, Centralcomputers, Micro Center and Best Buy without showing prices. Liliputing reported a barebones NUC 15 Pro Slim with the same chip at about $700 in April 2025, but that was a barebones kit rather than this 32GB/1TB configuration.
