Interior Impressions


The interior of the BFG ES-800 is like nothing we have ever seen before. It looks like everything has been turned upside-down and to tell you the truth, this layout is actually quite brilliant. Borrowing from the design points of a cross-flow (read: single 80mm exhaust fan) power supply, portions of this design expose certain capacitors to more direct airflow by turning them on their side. Even though this means a lot more intricate PCB design, it cools off certain components much more effectively. For those of you wondering, this power supply is built by Andyson who is counted as one of the better OEMs in the industry for higher-end units.

There are actually three different 105°C-rated primary capacitors in this power supply: two of them are Hitachis while the other one is a Nippon Chemi-Con. These can be considered extremely good choices since they represent some of the best capacitor manufacturers on the market.


The secondary filtering stage has a forest of Nippon Chemi-Con caps along with what looks like the odd CapXon here and there. Once again, these are very good component choices and a definite step in the right direction from what we saw with the Topower-designed 800W. Meanwhile, there is also an extremely well-appointed input filtering section closer to the rear of this power supply.


There is an inverted PCB closer to the back of the ES-800 where we can see the quality of the soldering used on this power supply and it is overall quite good. So far we have seen all of one +12V transformer and there is another, smaller transformer hiding below this PCB and it is paired up with yet more Nippon Chemi-Con capacitors.
