Despite the high capacity and compact dimensions, the PCB has enough clearance between its components to allow for good airflow. The design differs from the Leadex V Platinum 1000 I reviewed about a year ago at Tom’s Hardware. The only heatsink resides on the primary side, hosting the bridge rectifiers and the APFC converter’s parts. The main FETs, installed in a full-bridge topology, are on a vertical board before the AC receptacle. A metallic shield is installed on the same board, with a dual role, cooling down the PCB and reducing EMI emissions.

The 12V FETs are on two vertical boards to save space, and the VRMs handling the minor rails are on the PCB. Usually, the VRMs are on daughter boards and, in some cases, on the modular PCB, but SF chose this way to minimize energy losses. The build quality is high. SF used quality parts, including Infineon FETs and Chemi-Con capacitors. I am not sure about the cooling fan because I haven’t met this brand before. From my experience, it looks to be of lower quality compared to Hong Hua’s corresponding products.

  1. Why no inclusion of other atx 3 psus you tested like Msi etc? This doesn’t seem best way to inform users

    1. Different categories, the MSI unit I reviewed is digital and more expensive. I also try to keep the graphs small enough for mobile browsing. I can input 200x PSUs if I wanted, but the graphs wouldn’t be usable.
