AAEON IMBA-Q87A - Manual (Page 27)

2-19 Chapter 2: Motherboard information
IMPORTANT:
• For a fully configured system, we recommend that you use a power supply
unit (PSU) that complies with ATX 12 V Specification 2.0 (or later version)
and provides a minimum power of 230W.
• We recommend that you use a PSU with higher power output when
configuring a system with more power-consuming devices. The system
may become unstable or may not boot up if the power is inadequate.
