'''BTX''' (for '''Balanced Technology eXtended''') is a [[form factor (design)|form factor]] for [[motherboard]]s, originally intended to be the replacement for the aging [[ATX]] [[motherboard form factor]] in late 2004 and early 2005.

It was designed to alleviate some of the issues that arose from using newer technologies (which often demand more power and create more heat) on motherboards compliant with the circa 1996 [[ATX]] specification. The ATX and BTX standards were both proposed by [[Intel]]. However, future development of BTX retail products by [[Intel]] was canceled in September 2006 following Intel's decision to refocus on low-power CPUs after suffering scaling and thermal issues with the [[Pentium 4]].

The first company to implement BTX was [[Gateway Inc]], followed by [[Dell]] and MPC.  The first generation of [[Apple Inc.|Apple's]] [[Mac Pro#1st generation (tower)|Mac Pro]] used some elements of the BTX design system as well, but was not BTX-compliant, instead using a proprietary form factor.
