We recommend EVGA's Supernova G2 PSUs in our System Guide, but the series has previously bottomed out at 750W—perfect for our top-end builds, but overkill for less demanding systems. EVGA is filling in the gap with a pair of new Supernova G2s: one pumping out 650W, the other a more modest 550W. Those figures are more in line with the needs of our Budget Box and Sweet Spot builds.
Aside from the output ratings, these more modest Supernovas mostly differ in the number of PCIe power connectors on tap. The 550W version features twin eight-pin connectors, while the 650W adds another pair of six-pin connectors to the pile. The 550W version offers 45.8A of capacity on the all-important 12V rail, while the 650W bumps that up to 54.1A.
Both Supernovas also feature fully-modular cabling, 100% Japanese capacitors, 80 Plus Gold efficiency ratings, and semi-silent fans that don't spin below 45° C. Most impressively, both of these units are backed up with seven-year warranties. We've contacted EVGA for pricing and availability info.
