An Overclock.net member, "shilka", posted late last month over the failure of power protection in EVGA's SuperNova B3 power supplies, specifically the 450 and 850 W models. This adds to the concerns first raised by Tom's Hardware, one of whose review units created fireworks. Normally, for a product that has been on the market for some time, as the B3 series has, one could chalk up such incidents to a faulty batch. But it appears that might not be the case, considering JonnyGuru also reviewed EVGA's B3 and did not encounter any fire hazards.
It has subsequently emerged that the sample provided by EVGA to JonnyGuru was manufactured by Super Flower, whose Leadex platform is well known for its performance and high quality. Aris of Tom's Hardware (and TechPowerUp), however, bought their review sample from a retail outlet. The manufacturing of the latter had been outsourced to RSY, with (in this case) a resulting decline in build quality. It remains unclear whether Super Flower outsourced its production, or if EVGA is using multiple suppliers or switched manufacturers all together. Regardless, lesser quality PSUs would appear to be in stores in comparison to what was reviewed at JonnyGuru, arguably the most influential review site for PSUs.
