150W Mini Computer Power Supply Buyer's Guide

The market for 150W mini computer power supplies in 2026 is rapidly transitioning from internal DC-DC modules (PicoPSU) toward external Gallium Nitride (GaN) adapters, driven by the need for higher power density and better thermal management in ultra-compact builds Alibaba.

Market Trends & Technical Insights

* GaN Dominance: GaN technology has become the B2B standard, offering 90%+ efficiency and a 30-50% reduction in size compared to traditional silicon-based units Alibaba. The GaN adapter market is expected to grow at a 6.3% CAGR through 2030 Alibaba.

* Price Increases: PSUs and cooling components are seeing significant price hikes starting in February 2026 due to supply chain shifts Tweaktown. GaN units typically command a 30-60% premium over standard adapters Alibaba.

* Shift in Form Factors: While PicoPSUs remain a niche for extreme DIYers, mainstream mini-PCs are adopting external GaN bricks or integrated SFF docks using Thunderbolt 5 or Oculink for power delivery Alibaba Hardwarecanucks.

Product Analysis & Sourcing Data

Sourcing data reveals three primary product categories for 150W mini PC applications:

1Pico ATX Modules (DC-DC): These compact modules (e.g., RGeek 150W) plug directly into the motherboard and require a separate 12V AC/DC brick. Prices range from $14.50–$15.73 for bulk orders Alibaba.
2External GaN Adapters: High-efficiency bricks specifically designed for industrial mini PCs and workstations. Units from suppliers like Shenzhen Huikeyuan are available around $18.90–$20.00 Alibaba.
3Flex-ATX (1U) PSUs: Internal power units for compact servers and ITX chassis. 1U Flex units (e.g., from Guangzhou Hengyu) offer standard server-grade reliability at roughly $28.00 per unit Alibaba.
