EVGA Debuts the Budget B3 Series PSUs

Posted by at 9:35 am on April 12, 2017

EVGA‘s new B3 PSUs have launched, featuring lots of upgrades compared to the previous B2 line, plus covering a wider wattage range. The OEM is again Super Flower, which is definitely an advantage because SF is highly respected .

The platform has been upgraded, and in addition to the fully modular cable design, EVGA also added a semi-passive mode, a Hydraulic Dynamic Bearing fan, and (according to EVGA), tighter load regulations (<2%). The 450W-650W units have 150mm depth, whereas the 750W and 850W models are 10mm longer. Efficiency remains at the same level–80 PLUS Bronze certified.

All new B3s use a modern platform, featuring an LLC converter on the primary side and DC-DC converters on the secondary side, for the generation of the minor rails. Given those high-end specs, this platform could easily achieve significantly higher efficiency levels, but EVGA wanted it to stay at the same levels as its previous PSU line so as to avoid creating internal competition.

The B3 line positioned between the GQ (FSP OEM) and BQ (HEC and Andyson OEMs) lines, and they’re backed by a five-year warranty.
