Component Analysis

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



This platform looks to be made by MEIC, which also makes the AORUS P850 and P750 units. The design is very clean, with no cables blocking airflow, and the heatsinks are very small. Build quality is high, but lower-end manufacturers provide some of the key components. I am referring to the APFC and primary switching FETs. The capacitors on the secondary side are provided by an unknown manufacturer—I couldn't find any detailed information on these caps.


The transient filter uses four Y and a pair of X caps, two CM chokes, a discharge IC, and an MOV.


Surge and inrush current protections are handled by an MOV and an NTC thermistor-relay combination.


The two bridge rectifiers can handle up to 20 A combined.


The APFC converter uses two Jilin Sino-Microelectronics FETs and a single boost diode provided by the same manufacturer. Chemi-Con provides the bulk cap, and it does not have enough capacity to allow for a hold up time of over 17 ms.


Jilin Sino-Microelectronics provides the main FETs, and as you can see, they didn't survive my tests. They died in a glorified way, making one of the loudest bangs I have ever heard. The main FETs are arranged in a half-bridge topology, and an LLC resonant converter is also used to boost efficiency. The resonant controller is a Champion CM6901X.


Four NCE Power FETs regulate the +12 V rail.


The VRMs handling the minor rails use four Alpha & Omega FETs and a pair of uPI-Semi PWM controllers.


I have never encountered these cap brands before, so I am very skeptical about their reliability. Besides electrolytic caps, a dozen polymers are also used, provided by an unknown manufacturer.


The 5VSB circuit uses an SBR on its secondary side, and the standby PWM controller is a PR6249H IC.


The modular board hosts four electrolytic and two polymer caps. Four bus bars connect this board to the main one.


Soldering quality is good.


Some SMD components are not correctly aligned, but this is not a significant issue as long as they are properly soldered to the PCB.


The rifle bearing fan is provided by Yate Loon. Mostly known for affordable products, their fans cannot compete with high-end fans.


Gigabyte advertises it as a hydraulic dynamic bearing, but I broke it apart to find that it uses a rifle bearing. Still better than a plain sleeve bearing, it is inferior to a true HDB/FDB.
