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. This is the same model that features in the P2 1200 supply.
The EVGA SuperNova P2 1600 is created by OEM partner Super Flower (based on their Leadex Platform). 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 DC-DC converters for minor rail generation. Soldering quality of the main PCB is good.
Transient filtering starts at the AC Receptacle. The main PCB houses the second stage and features 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 four high grade 105c rated Japanese Nippon Chemi-Con capacitors (1200 P2 uses KMQ series caps, 1600 P2 uses KMW series). These are rated 400V 390uF – combining for a total of 1560uF. By comparison the P2 1200 combined total is 1120uF. Secondary stage capacitors are all Japanese 105c rated Nippon Chemi Con. Top marks to the Super Flower engineers for not making any compromises with the design.
