Corsair TX vs. OCZ ZT 550W

OCZ ZT550W Internal Design and Fan

OCZ uses a 140mm fan from Yate Loon with a ball bearing. The product number is D14BH-12 and it takes 0.70A. Again we would like to see a better solution here. Like mentioned before Great Wall is the manufacturer of the ZT-series.The PCB for the modular ports should get a thin plastic sheet since it's very close to the main PCB. Generally, the power supply case is well filled out. OCZ uses capacitors from Teapo and Rubycon (ZLH, a very good choice). Moreover EMI filtering is equipped well, but there is no MOV for overvoltage protection. The ferrite core on the conductors helps to reduce EMC troubles with high frequency current. All output voltages got their own regulation circuit; both +3.3 V and +5V have a magnetic amplifier. Crossload tests should be no problem with this configuration.
