EPS1U Power Supply Design Guide, V1.1

1Purpose

This specification defines a non-redundant power supply that supports 1U rack mount entry server systems. The entry-level power supply is not intended to be a hot swap type of power supply. The parameters of this supply are defined in this specification for open industry use. This specification defines a 125W, 250 W and 350 W power supply with six outputs; 3.3 V, 5 V, 12 V, -12 V, and 5 VSB. The form factor fits into a 1U system and provides a wire harness or docking solution for output connections. An IEC connector is provided on the external face for AC input to the power supply. The power supply contains fans for cooling, while meeting acoustic requirements.

2Conceptual Overview

In the Entry server market, the bulk power system must source power on several output rails.

These rails are typically as follows:

∙+3.3 V

∙+5 V

∙+12 V

∙–12 V

∙5V standby

NOTE

Local DC-DC converters shall be utilized for processor power, and will ideally convert power from the +12 V rail, however, they may also convert power from other rails.

The bulk power system may be an n+1 redundant power system or a non-redundant power system.
