Component Analysis

Before reading this page, we strongly suggest looking at this article, which will help you better understand the insides of a PSU.



This budget platform is made by Casecom, an OEM with a ton of experience creating affordable platforms with a high dollar to performance ratio. Casecom's production capability is not as large as CWT's, for example, but can still provide decent platforms at affordable prices, which is why several budget-oriented brands prefer this OEM.


The transient/EMI filter stages have all the necessary parts, but need further tuning to improve EMI suppression.


A Metal Oxide Varistor (MOV) handles voltage surges, while an NTC thermistor suppresses large inrush currents. A bypass relay does not support the latter. The NTC thermistor should be of higher resistance to handle inrush currents more effectively.


The bridge rectifier is not bolted to the heatsink, although it is nearby. With 230 V input, it won't be put under a lot of stress. That said, it would still be nice to see it firmly attached to the heatsink.


The APFC converter uses a single First Semi FET and a WeEn boost diode. The bulk caps are by Teapo, and their combined total capacity is 360 uF.


The combo APFC/PWM controller is a Champion CM6800TX.


The main FETs are two First Semi FIR10N50Fs installed in a double-forward topology.


The unit's main transformer isolates the primary from the secondary side and lowers the voltage.


The FETs regulating the +12 V rail are bolted to a heatsink.


Two DC-DC converters generate the minor rails. They use four Maplesemi FETs, and their joint PWM controller is by Anpec.


The electrolytic caps are by Teapo, and the polymer ones by NJcon. I am not that fond of the Teapo SC line, but you usually find considerably lower-quality filtering caps in such budget PSUs. In any case, the Teapo caps will easily outlive the provided three-year warranty under normal operating temperatures.


The standby PWM controller is a DP2358.


The supervisor IC is a Grenergy GR8329N providing the essential protection features.


Soldering quality is mediocre.


The cooling fan has MIFCOM branding, but Scythe's factory makes it. It uses a fluid dynamic bearing, so it is of good quality. You usually find sleeve-bearing fans in budget PSUs.
