EVGA has one of the most complete PSU portfolios today, with many products covering all market segments from low to high end. One of the most popular PSU lines EVGA offers is the G2 PSU series, which lies of units made by Super Flower that offer outstanding functionality/dollar.
Like other G2 PSUs, the 550 W model is based on Super Flower’s Leadex platform, offering 80 Plus proficiency along with a fully modular cabling design and a semi-passive operation. Because of the highly efficient platform, the relaxed fan profile, and a long-lasting passive mode, we expect this unit to offer very quiet operation, even under tough conditions.

In the cooling section, a 140 mm double ball-bearing fan removes the hot air from the unit, and due to its quality bearings and semi-passive operation we expect it to have a very long lifetime.
The PSU’s dimensions are typical for this capacity, and at seven years the warranty is very long, although it doesn’t reach the 10-year period that covers the higher capacity G2 members.
The EVGA SuperNOVA 550 G2 is one of the best performers in the midcapacity category. It only loses to the much more expensive, Platinum-proficiency Seasonic fan-less PSU, which is based on a higher-level platform.
From the above graph, you can also see that the functionality difference between EVGA’s 550 G2 and the 550 GS models is quite large, mostly because of the poor ripple suppression on the +12V rail in the GS unit.
A high-performance PSU that performs silent operation even under tough conditions. Its Japanese capacitors and long warranty, along with the double ball bearing fan, will offer extended peace of mind to its future owners.
