**Change made:** "电源适配器支架" → "电源供应器支架" The original translation is nearly correct, but "电源适配器" (power adapter) is less precise than "电源供应器" (power supply) in professional audio equipment contexts. For B2B audio trade copy, "电源供应器" is the standard technical term for the power supply unit and better matches the English "Power Supply Holder."
