Both families offer variable-speed fans, unflinching voltage stability, and other performance specifications that are so important to high-end, performance-oriented PC systems. "We are expanding our top two PSU lines thanks to the continued strong demand from performance enthusiasts for highly reliable, super-efficient power supplies." said Ruben Mookerjee, VP and General Manager for Components at Corsair.

These new models provide expert system builders with even more flexibility in choosing the right power supply for their needs." The Professional Series HX1050 is available from Corsair-authorized retailers worldwide for a US suggested retail price of $239 USD.
