BFG Technologies is a large retailer who is mostly active on theAmerican market. We have reviewed this company’s graphicscards and now it’s time for us to check out its PSUs as well.It looks like a strong trend for graphics card, memory and coolermakers to begin to produce power supplies in addition to theirmain, traditional products.

This 800W ES series power supply is a senior PSU model from BFG.The manufacturer claims this series to have high efficiency. Whilethe efficiency of most PSUs drops quickly at low loads, the ESseries models ensure an 80% or higher efficiency even at a load of10%.

The exterior of this power supply is quite traditional: a blackglossy case with BFG logos pressed out in the side panels, and alarge fan. The small vent grid in the side panel may catch youreye. Why is it there if a perforated external panel of the PSU isnear?

Looking into the case, you can see an active PFC card near thatgrid. The card is photographed with the solder facing up. So, theadditional ventilation is necessary to cool the PFC card moreefficiently.

The real manufacturer of this power supply is Andyson. This namemay be familiar to you by Hiper power supplies, for example. By theway, Hiper has changed its supplier recently and switched toChannel Well.
Andyson PSUs had raised my criticism for their low quality ofsoldering before. Fortunately, I didn’t find any problems onexamining the ES-800.
