Corsair AX750 80 Plus Gold: Putting Corsair's Best to the Testby Martin Kaffei on November 30, 2010 12:00 AM EST
Opening the casing reveals a clean design with a good layout. The phase and neutral conductors as well as the transformer look undersized at first, but the new resonant topology and more active controlled parts allow the manufacturer to use smaller components. Like Seasonic, this PSU has ZVS (Zero Voltage Switiching) that reduces power loss. Moreover, the soft switching is better for EMI.
All capacitors come from Nippon Chemi-Con and there are some all solid ones in the secondary circuit, but the KMR models are a usual choice for high-end PSUs. It would be nice to see some other brands or types; however, all parts are high-quality. There is a line filtering stage in the entrance and many SMDs at the backside of the PCB. The champion IC is on a sister-PCB up top. The overall design definelty looks like an X-460FL with more caps. The only point of criticism is that the fan connector could be glued down, but that's a minor issue at best.
