1 Introduction

1.1 TFX12V Scope

This document provides design suggestions for a small form factor power supply that is primarily intended for use with small form factor system designs (9-15 liters in total system volume). It should not be inferred that all Thin Form Factor with 12 Volt connector (TFX12V) power supplies must conform exactly to the content of this document, though there are key parameters that define mechanical fit across a common set of platforms.

Since power supply needs vary depending on system configuration, the design specifics described are not intended to support all possible systems.

1.2 TFX12V Overview

This section provides a brief overview of the unique features of the Thin Form Factor with 12 Volt connector (TFX12V) power supply design and a summary of the changes included in revision 1.2.

1.2.1Small System Optimized Profile

The increase in demand for smaller systems results in unique system layout challenges. The Thin Form Factor with 12 Volt connector (TFX12V) configuration has been optimized for small and low profile microATX and FlexATX system layouts. The long narrow profile of the power supply (shown in Figure 1) fits easily into low profile systems. The fan placement can be used to efficiently exhaust air from the processor and core area of the motherboard, making possible smaller, more efficient systems using common industry ingredients.
