Gigabyte is readying a series of more inexpensive variants of PowerRock mainstream PSUs, the PowerRock EX. Available in similar models of 300W, 350W, 400W, 450W and 500W, the PowerRock EX lacks 80 Plus compliance and sleeved cabling found with the original PowerRock series. The new PSUs are ATX v2.0 compliant, use Taiwan-made capacitors, feature dual 12V rail design for the 450W and 500W models, and single 12V rail design for the 300W, 350W, and 400W ones. OVP, OCP, UVP, and short-circuit protections come standard. The PSUs are cooled by a 120 mm fan, and have a rated MTBF of 100,000 hours. Gigabyte did not give out pricing or availability details.
