As part of the Computex 2012 show, Gigabyte demonstrated to us their new version of Ultra Durable. This fifth iteration of their power delivery combines their previous features with a new phase from International Rectifier, which is marketed to offer up to a 60°C lower temperature than traditional MOSFET solutions. Initially this new design is being paired with six motherboards, all designated with UP rather than UD in the name. The first of these we have in is the X79X-UP5 WiFi, which combines Ultra Durable 5 with the C606 chipset. The C606 chipset is the server version of the X79 chipset, which enables increased IO and up to eight SAS ports. Read on for the analysis and review.
