                Mini ITX, TFX, and Flex ATX power supplies as well as some small form factor PSUs that are compatible with certain pre-built systems, such as Dell, HP, and Compaq. A mini itx power supply is the standard for an ultra small form factor build and are quite commonly used in HTPC and reduced footprint builds. Some of the major manufacturers in this space include Solid Gear, FSP, and Athena Power. Flex ATX, TFX and Mini-ITX power supplies are popular for creating compact systems where size and low power draw is the most important factor. As a result, these PSUs must be highly efficient and physically smaller than their counterparts.

                FAQ & Section Info

                What is Mini ITX?



                Mini-ITX is a small form factor for PCs that generally does not require as much power as other form factors. Other small form factors are TFX and Flex ATX PSUs, which may act as replacements for pre-built systems and proprietary cases from manufacturers, such as Dell and HP, as well as some of the more unique power supplies we stock in this category. These are all smaller than ATX and are often used in compact desktop PCs and HTPCs.

                Why should I get Mini-ITX?
