Can You Upgrade This Mini PC?
Very limited upgrade potential. RAM is LPDDR5X soldered memory and cannot be upgraded. Only storage (M.2 SSD) is user-replaceable. This ultra-compact form factor prioritizes silence and efficiency over upgradeability. Best for users who will not change RAM capacity after purchase.
RAM — LPDDR5X Soldered (Non-Upgradeable)
The NUC 14 Performance comes with 16GB or 32GB LPDDR5X memory soldered directly to the motherboard. This cannot be upgraded, expanded, or replaced. Choose your RAM capacity at purchase time. This design reduces power consumption and heat, enabling fanless operation.
| Configuration | RAM Capacity | Power Draw | Typical Use |
|---|---|---|---|
| Standard | 16GB LPDDR5X | Lower (fanless) | Web, office, media playback |
| High-End | 32GB LPDDR5X | Slightly higher (fanless) | Light content creation, multitasking |
SSD Compatibility — M.2 2280 NVMe PCIe 4.0
One M.2 2280 NVMe slot with PCIe 4.0 support (up to 7.1 GB/s). This is the only storage upgrade point. PCIe 5.0 drives work at PCIe 4.0 speeds. Maximum recommended: 2TB.
Recommended upgrade parts:
- Samsung 990 EVO NVMe SSD — PCIe 4.0, excellent performance and value.
- External USB-C SSD Storage — Expand storage via Thunderbolt 4 without opening the case.
- Thunderbolt 4 Dock — Connect external drives and displays with a single cable.
| Product | Capacity | Interface | Speed | Price (UK) |
|---|---|---|---|---|
| Samsung 990 Pro | 500GB / 1TB / 2TB | PCIe 4.0 | 7.1 GB/s read | £50–160 |
| WD Black SN850X | 500GB / 1TB / 2TB | PCIe 4.0 | 7.1 GB/s read | £40–155 |
| Crucial P5 Plus | 1TB / 2TB | PCIe 4.0 | 6.6 GB/s read | £65–140 |
| SK Hynix Platinum P41 | 1TB / 2TB | PCIe 4.0 | 7.1 GB/s read | £90–160 |
Power Supply & Fanless Design
The 45W external PSU is minimal by modern standards. The ultra-low TDP (~28W) and LPDDR5X soldered memory eliminate the need for any active cooling. This is a completely fanless, passively cooled unit—ideal for silent studios, home theaters, and office environments. Zero thermal management issues.
Display & Thunderbolt 4
HDMI 2.1 and Thunderbolt 4 (with Alt Mode) enable dual-display setup. TB4 provides high-bandwidth external connectivity for docking, external storage, and future expansion. Extremely compact chassis design makes this the smallest ASUS mini PC.
WiFi 6E & Bluetooth 5.3
WiFi 6E (802.11ax) dual-band with tri-band support when available. Bluetooth 5.3 for low-latency wireless peripherals. 2.5GbE Ethernet for stable wired connections. WiFi module is soldered and not upgradeable.
Upgradeability Score
3/10 — Minimal upgradeability. RAM is soldered and non-upgradeable; storage is the only upgrade point. CPU, GPU, WiFi are fixed. Buy with the RAM capacity you need. Excellent for sealed, silent deployments.
FAQs
Can I upgrade the RAM in the NUC 14 Performance?
No. RAM is soldered LPDDR5X memory and cannot be upgraded, expanded, or replaced. Choose 16GB or 32GB at purchase.
Should I buy 16GB or 32GB?
16GB is sufficient for web browsing, office work, and media playback. 32GB is recommended for multitasking, light content creation, and running multiple applications simultaneously.
Is the M.2 slot upgradeable?
Yes, the single M.2 2280 NVMe slot is user-replaceable. You can upgrade the SSD to a larger or faster drive.
Can I use this for video editing?
With 32GB soldered RAM, the NUC 14 Performance can handle light to moderate 1080p editing. 4K editing is not recommended due to the single M.2 slot and non-upgradeable RAM limitation.
How quiet is the fanless design?
Completely silent. No moving parts, no fans. The passive cooling design produces zero noise, even under sustained load.
