APPENDIX B

Power Standards

The following table references the standard ATX power supply voltages, regulation (tolerance), and voltage ranges.¹⁵

The values listed here for the +5 V and +3.3 V supplies are referenced in Chapter 2 of Raspberry Pi Hardware Reference (Apress, 2014) as a basis for acceptable power supply ranges. When the BroadCom power specifications become known, they should be used instead.
