The EVGA SuperNova P2 1200 is created by OEM partner Super Flower. The primary side is using a full bridge topology with a LLC converter to help improve efficiency. The secondary side of the design incorporates a synchronous design for the rectification of the +12V rail with two DC-DC converters for minor rail generation. Soldering quality of the main PCB is good.

Transient filtering starts at the AC Receptacle which consists initially of a single X cap. The main PCB houses the second stage and features two CM chokes, two pairs of Y caps, two X caps and an MOV. Super Flower have built in a Transient Voltage Suppression diode to help protect against spiking.

The primary stage uses a pair of high grade 105C rated Japanese Nippon Chemi-Con capacitors. (KMQ series) These are rated 400V, 560uF – combining for a total of 1120uF. Secondary stage capacitors are all Japanese (Nippon Chemi-Con) and rated 105C. Top marks to Super Flower for not compromising here.
