Performance (40% of the final score) – scoring time has come. The performance of this little guy was kind of a mixed bag… it did some things better than others. We’ll start with the ripple control, which was a little disappointing for me. There, we had two outputs slipping into a scoring bracket down from excellence, so half a point will need to come off for each of those. Efficiency not only nailed Gold numbers but did Platinum most of the time, so no deduction there. Load regulation on the outputs was another minor weak point with the unit hitting “very good” numbers, so there will be a point removed there. Finally, the S&C point… this was entirely safe today, as those scope shots looked fantastic, so this category will end up with an 8.

Functionality (20% of the final score) – I really have nothing to complain about, here. We had a decent number of accessories, I’m okay with the cabling, the documentation was good, and we even got a semi-fanless mode. I’ll do a 10 here.

Value (20% of the final score) – you’ll need $129.99 at EVGA’s website to get one of these at the moment. By contrast, NewEgg is pushing the Corsair SF600 for $114.96 and the Silverstone SX650-G for $148.99. I have to ask… how badly do you need that extra 50 watts? The Corsair is arguably the better performing unit, yet prices are not far apart. Given these prices, I’d have to say this unit is a good but not great value. 8.

Build Quality (20% of the final score) – I found nothing to score against, here. No solder issues, no fan issues, no niggles with the electrical design… we’re doing a 10 here.

EVGA’s first entry into the SFX power supply market is here, and it’s mostly a well built and decent performing example of power supply engineering. There’s no doubt it still needs some work to compete with the leaders in this space, but the 650GM gives us one more option in a market that still seems really lacking to me.


  • excellent build quality
  • semi-fanless
  • fully modular
  • Platinum efficiency below 75% load

The BAD:
