A Look Inside & Component Analysis

Before reading this page, we strongly suggest a look at this article, which will help you understand the internal components of a PSU much better. Our main tool for the disassembly of the PSU is a Thermaltronics TMT-9000S soldering and rework station. It is of extreme quality and is equipped with a matching de-soldering gun. With such equipment in hand, breaking apart every PSU is like a walk in the park!


This unit, like all other G2, P2 and T2 units, is made by Super Flower, based on their highly popular Leadex platform, which is among the best currently available platforms. Super Flower has managed to establish a very good name for itself, and EVGA surely played a key role in their ability to do so since most of their PSU offerings are based on Super Flower's platforms, while making EVGA quite a popular choice in the US where Super Flower doesn't have a retail presence.



The primary side uses a half-bridge topology with an LLC resonant converter for decreased energy losses. The +12V rail in the secondary side is regulated by fets, and two DC-DC converters generate the minor rails. The design is clean, and the heatsinks are large enough for the PSU to run in passive mode for quite a while without it significantly stressing this unit's passive and active components.


The small PCB behind the AC receptacle doesn't host any components of the transient filter as all of them, two CM chokes, two X caps, two pairs of Y caps, and an MOV, are on the main PCB.


A single bridge rectifier is used, and we weren't able to identify it because its markings were hidden by the APFC heatsink.


Two Infineon IPA50R250CP fets and a C3D06060A boost diode are used by the APFC converter. The single bulk cap is provided by Nippon Chemi-Con (400 V, 470 uF, 105°C, KMQ series).


An NTC thermistor protects the PSU against large inrush currents, and a close-by electromagnetic relay isolates it from the circuit once it finishes its job.


The tiny sealed PCB in these photos houses the APFC controller, an NCP1653A IC. It is the same for all Leadex models.


The standby PWM controller is an IC with a "29604" marking, which doesn't clue us in on its specifications.


The LLC resonant controller is a proprietary IC with markings AA9013. The same IC handles the PSU's protection features.


Two Infineon IPA50R199CP fets arranged into a half-bridge topology are used as main switches.


In the secondary side, two small heatsinks host four Infineon IPP041N04N G fets. These regulate the +12V rail. In-between these heatsinks are several electrolytic caps by Chemi-Con; the caps are used for ripple-filtering purposes.


A pair of DC-DC converters generate the minor rails. The polymer caps found on these converters are provided by Chemi-Con.


The 5VSB rail is rectified by a Mospec S10C60C SBR (Schottky Barrier Rectifier). Next to the SBR is the fan-control board with an LM324ADC.


On the front of the modular PCB are many electrolytic and polymer caps. All are by Chemi-Con and offer some extra ripple filtering to the rails, allowing for amazing overall ripple suppression.


Soldering quality is quite good; however, it is definitely not top-notch. According to rumors on the web, Super Flower cannot meet demand with their own manufacturing lines, which had them hire the production lines of other vendors in order to produce more PSUs. If true, build quality may vary from that of their own products, although such also depends on the capabilities and the quality control of these third party production lines.


The fan is by Globe Fan, and its model number is RL4Z-B1402512M (140 mm, 12 V, 0.3 A, 1300 RPM, 92.16 CFM, 24.9 dBA). This fan uses double ball-bearings, so it will last for quite a long time.
