BFG ES Series BFGR800WESPSU (800W)
BFG Technologies is a large retailer who is mostly active on the American market. We have reviewed this company’s graphics cards 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 cooler makers to begin to produce power supplies in addition to their main, traditional products.
This 800W ES series power supply is a senior PSU model from BFG. The manufacturer claims this series to have high efficiency. While the efficiency of most PSUs drops quickly at low loads, the ES series models ensure an 80% or higher efficiency even at a load of 10%.
The exterior of this power supply is quite traditional: a black glossy case with BFG logos pressed out in the side panels, and a large fan. The small vent grid in the side panel may catch your eye. Why is it there if a perforated external panel of the PSU is near?
Looking into the case, you can see an active PFC card near that grid. The card is photographed with the solder facing up. So, the additional ventilation is necessary to cool the PFC card more efficiently.
The real manufacturer of this power supply is Andyson. This name may be familiar to you by Hiper power supplies, for example. By the way, Hiper has changed its supplier recently and switched to Channel Well.
Andyson PSUs had raised my criticism for their low quality of soldering before. Fortunately, I didn’t find any problems on examining the ES-800.
