Performance (40% of the final score) – this should be a breeze today. Voltage regulation was really the only weak spot, and it’s not much of one at all coming in at 1.17% in the hot tests. That’s excellent performance, warranting a mere half point deduction for not getting up to mythic level. Efficiency was pretty solidly Platinum as we were promised, so no deduction there. The same goes for the power on spike tests, because this unit deserves the entire S&C point. And finally, the ripple control. Excellent all the way along. That means we have a 9.5 in this category.

Functionality (20% of the final score) – I have two deductions to make here. Not with the documentation, because SilverStone rules documentation. Not with the cable count or connectors, though four PCI-e connectors is a little much for a unit this size. Where I take issue is once again the extreme amount of ribbons on the ATX connector and the fact that, for a unit costing as much as this one does, it is very light on extra goodies. I really wanted at least something for tying cables out of the way, plus the ATX adapter plate SilverStone quit providing. Otherwise, this category’s good with a 9.

Value (20% of the final score) – I’ll not mince words… $189.99 at Amazon makes this obscenely expensive, and I’m rather torn about how to score this. On one hand, SilverStone now has the fanless SFX market all to themselves. This unit competes with nothing else out there, really. But if you don’t mind throwing a fan back into your power supply, things look a lot different. At NewEgg, the most expensive fanned SFX unit is the Enermax Revolution 650W, and it is sixty-five dollars less money. Corsair SF600? Seventy-five dollars less money. Normally, a product like this would get a perfect score for having no competition. But this price is so far above the fanned units available that I can’t do it. It’s a niche product with this price on it, and I don’t think it’s going to be a hot seller for SilverStone as a result. So, the best I can do here will be an 8.

Build Quality (20% of the final score) – Enhance brought every last bit of talent to this party… there are no issues at all to score against. 10.

SUMMARY

First, SilverStone decided to set themselves apart by pushing power density to its limit. Now, they’re at it again by giving us our first SFX-L shaped fanless power supply. There’s no denying that this little guy is definitely one of a kind, and likely will find a good home in applications that cannot be served by any other power supply. But the cost of buying one of these is so high at the moment that I’m rather certain a lot of those applications will be tossed aside by people asking themselves if they really need such a small fanless unit. But you have to admit, SilverStone certainly knows how to get our attention.

The GOOD:

  • excellent voltage regulation
  • fantastic build quality
  • excellent ripple control
  • tons of connectors
  • itsy bitsy teeny weeny fanless PSU machiney

The BAD:

  • nothing

The MEDIOCRE:

  • VERY expensive, with good reason
