What is Balance Technology Extended?
Balance Technology Extended (BTX) is a motherboard form factor originally intended to replace the 2004 and 2005 ATX motherboard. BTX is designed to lower power consumption and reduce heat. In addition, it uses an improved technology that includes the Advanced Technology Attachment (ATA) serial, Universal Serial Bus (USB) 2.0, and Peripheral Component Interconnect (PCI) Express. It is standardized by Intel and not backwards compatible with the ATX.
The BTX was introduced first by Gateway Inc. and then by MPC Corporation and Dell Inc. It was also used in Apple's Mac Pro but was not BTX compatible. In September 2006 Intel stopped development; This was largely due to the lack of backward compatibility with the ATX form factor.
The Balanced Balance technology was developed to reduce the problems of the 1996 ATX standards by reducing power consumption and heat generation. The BTX standards provide an efficient design for small and large systems and new features such as:
An increased number of expansion slots
Better electrical and thermal regulation
Multiple system sizes and configurations
Support for high mass motherboard components
Improved cooling performance with a straighter airflow
Reduced latency between northbridge and southbridge
Better component placement for backplane I / O controllers
Lower height requirements that benefit system integration for blade servers and rack mounts
One of the most recognized features is the improved thermal module. It sits at the front of the board and draws in the components that generate the most heat: the chipset, the CPU, and the graphics card. The thermal module consists of a heat sink, fan, duct, seal and clip. There are two types of thermal modules, Type 1 and Type II. In most cases, Type I is used, while Type II is used for smaller personal computers (PCs).
Although the BTX was originally intended to replace the 2004 and 2005 ATX motherboard, the design of the form factor was not compatible with the ATX. Overall, the BTX motherboard and thermal module do not fit in an ATX case, but the ATX power supply works in a normal and large BTX case.
