As users are becoming more and more aware of how PSUs operate and what the real energy requirements of their systems are, sales of high wattage units decrease in relevance to middle range units. Many manufacturers realize that and they began marketing high performance products of reasonable power output and pricing instead of focusing their efforts on high output units. In that light, EVGA expanded their very popular G2 PSU series downwards, adding 550W and 650W models to it.

EVGA's G2 series is synonymous with the excellent balance between cost, quality and performance. We have seen their capabilities in our review of the 850W version. After all, there is good reason why the Super Flower Leadex platform is so popular. The new 550W and 650W models are physically smaller but share the same features, so it is very likely that they are based on a Super Flower platform as well.

According to EVGA, the main features of the new 550 G2 and 650 G2 PSUs are:

  • 80 PLUS Gold certified, with 90% (115VAC) / 92% (220VAC~240VAC) efficiency or higher under typical loads
  • Highest quality Japanese brand capacitors ensure long-term reliability
  • Fully Modular to reduce clutter and improve airflow
  • NVIDIA SLI & AMD Crossfire Ready
  • Heavy-duty protections, including OVP (Over Voltage Protection), UVP (Under Voltage Protection), OCP (Over Current Protection), OPP (Over Power Protection), and SCP (Short Circuit Protection)
  • Ultra Quiet Fan with ECO Intelligent Thermal Control Fan system (Zero Fan Noise < 45°C)
  • Unbeatable 7 Year Warranty and unparalleled EVGA Customer Support.

We should note that both units are rated at 50°C and have a ridiculous number of connectors for their power output. Even the 550W version has three PCI Express connectors (two 8 pin and one 6 pin) and nine SATA connectors. Apparently, EVGA is very confident about the capabilities of their new units - or of their OCP, at least. Nevertheless, the 550W version should be able to easily power any system with a single CPU and a single GPU, with the possible exception that the extreme combination of an AMD FX-9590 and an R9 295X2.

The new G2 series units are available as of the 12th of June.

    Yep. I suppose having so much restriction helps to sell more pricey PSUs in the line. The 850W G2 was quite noisy in techpowerup's testing.

    Well according to the JohnyGuru review of the G2 650 it's still Superflower.. so yeah Id assmume the 550 would be as well.. Would be nice if you could get a review in on the 550 E. Since there seems to be some positive feedback about lower wattage psu's for Anandtech.

    I've heard SuperFlower has a hard time keeping up with demand maybe that's why Evga is also using FSP/Seasonic on certain models.

    Oh really. G2's are SF, GS's are Seasonic. Is there anything unclear in that?
    And since Super Flower is not a big company, they're really having a hard time right now. That's why EVGA went with Seasonic also to at least have something to sell.

    According to Johnny Guru My corsair tx850 is made by Seasonic and they make quality PSU's so no complaints here after 4+ years

    I love my G2 1050, so I'm sure their more mainstream options are great as well.

    "EVGA's G2 series is synonymous with the excellent balance between cost, quality and performance."

    The 850W G2 showed worse temperature and noise performance in techpowerup's testing than the often maligned Corsair RM.

    850watt psu looks good. Might be my next psu.
