EVGA SuperNova P2 1200 PSU Review

Allan 'Zardon' Campbell December 3, 2014 Featured Announcement, Power Supplies

The fan is a ‘Globe' double ball bearing model, number RL4Z-B1402512EH. This is rated 12V, 0.6A with a maximum speed of 2,000 rpm, airflow 153.47cfm. Maximum noise rating is officially 39.5dBa. We will measure noise later in the review.

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.
