Under the Hood
Here are a few pictures showing the layout and components inside the BFG Tech ES-800 power supply. The overall build quality appears to be very good but the layout is unique. The ES-800 was designed from the ground up without relying on traditional designs. PCBs are positioned perpendicular to the cooling fan for improved air circulation.
For the new ES-800 800W power supply, BFG Tech selected Andyson as their OEM. Andyson is no stranger to the PC power supply market and you have probably seen other examples of their work branded by Ultra, Hiper, Aerocool, Sunbeamtech, etc.
All the capacitors on the primary are Japanese brands (Nippon Chemi-Con and Hitachi).
All of the secondary capacitors are also Nippon Chemi-Con and rated for 105°C. Very good!
