NZXT Hale82 V2 550W White PSU Review
The Interior of the NZXT Hale82 V2 550W
The 135mm fan with the white blades and black frame has been provided by Hong Sheng, a good but not really popular manufacturer amongst power supply makers. The A1425M12S is a 1500RPM fan with a sleeve bearing.
NZXT also had the PCB made white, for some reason which we cannot comprehend, as it will not be visible to the end user under any circumstances. Sirtec is the OEM behind this power supply, a company known for their proclivity towards mainstream designs. In terms of technology, the Hale82 V2 is nothing special by todays standards and, even though the quality of the soldering and assembly is very good, the quality of the components appears rather mediocre.
The filtering stage begins at the rear of the AC receptacle and continues on the main PCB. In total there are four Y capacitors, two X capacitors, two filtering chokes and a MOV, forming a decent filtering circuit. The main input converter can be seen on a small, dedicated heatsink.
The large heatsink near the edge of the unit holds the active components of the APFC stage, two transistors and a diode. The passive components are a large coil and an 85C capacitor by Teapo. After the PFC stage, the primary stage begins, with two transistors forming a typical half-bridge configuration.
Seven transistors, four for the 12V line and three for the minor voltage lines, form the secondary stage of the NZXT Hale82. Group regulation indicates that the 12V and 5V lines are regulated via the same channel, which is definitely not going to pass any Haswell approval tests. The capacitors at the secondary side of this power supply are all supplied by SuScon, a mediocre manufacturer.
