Performance (40% of the final score) – you probably already know what I’m going to say here. Voltage regulation was excellent, averaging 0.9% in the hot box. No points deducted. Efficiency was a pass for Gold both times. No deduction. Ripple control was amazing, and probably the best I’ve ever seen, so definitely no deduction there. I saw no issues with anything else, so this unit gets a 10 here.

Functionality (20% of the final score) – this unit gets everything right. Even the CPU cable, which I thought was terrible on the 650W, is done right here today. The semi-fanless mode works well, the manual is decent, we got lots of connectors to power anything a 550W unit should power, and the box came with more goodies than I tend to expect with such a small unit. 10.

Value (20% of the final score) – you can get one of these for $84.99 at NewEgg right now. That’s a fair bit for a unit this size these days, but as always EVGA is right at the bottom of the cost pile when it comes to 80 Plus Gold and full modularity. The nearest competition is their own 550W GS unit at one dollar more money. This is nuts. How are you making any money on these, EVGA? 10.

Build Quality (20% of the final score) – oh, snap… EVGA just got another perfect total score. There’s nothing wrong with this unit. Nothing. 10.

What more can one say about these units that hasn’t been said? The score speaks for itself, really. This thing has the best ripple control I’ve seen, it’s efficient, and it’s cheap compared to what little competition it actually does have. I seriously cannot think of one thing to complain about on this little guy. Yeah, having three total PCI-e connectors is a little odd, but that’s no complaint for a unit this small. If you need to power two video cards, you’re usually in need of something a little bigger than 550 watts.


  • excellent voltage stability
  • beyond excellent ripple control
  • fully modular
  • affordable
  • lots of included goodies

The BAD:

  • nothing


  • nothing
