Performance (40% of the final score) - and now we come to the scoring. This one will be a bit tricky. On one hand, we had some of the best voltage regulation I've ever seen. But on the other hand, we also had borderline mediocre overshoot transient suppression on those tests. On one hand, we had very good ripple and noise suppression on the 12V and 3.3V side of things. On the other hand, we had only so-so ripple suppression on the 5V rail. That leaves me with four hands to consider here, along with build quality that I would like to see improved just a bit. So, I'll give this unit an 8.5 here today.

Functionality (20% of the final score) - the jury is out for me on whether or not the flat cabling is any advantage over the usual sleeved wire approach. However, it's undeniably a better approach than the individual unsleeved wiring present on a lot of low end and midgrade models. Aside from this, the unit does pretty well in this category, with more than enough connectors to get the job done for any system needing a unit of this size. That said, I'm going to take a point off for the huge cable exit on the enclosure, and the lack of any provisions for securing the wiring to the case. 9.

Value (30% of the final score) - I can't find a retail price on this yet, so I'll have to go with the MSRP of $99.99 to determine this score. You know, that's actually not half bad. Over at Newegg, for example, there are quite a few units around that price that weigh in at 750 watts, as well as a few 850W models. I'm not sure this is the very best unit you can get for the price, but it's not a bad value at all methinks. 8.5.

Aesthetics (10% of the final score) - as always, it does my heart good to see matte black. However, I do have to pull a point or two off for the rainbow of unsleeved wires and that big hole in the back the wires come through. Now, that's just my opinion, and the reason why this category gets so little weight in the final score. So, don't shoot me for putting out this here 8.









Total Score



The Topower KC-750 almost, but not quite, earned a recommendation here today. It has a lot to offer, not the least of which is abnormally good voltage regulation. Unfortunately, there were also a few minor things counting against it, like the at-spec ripple on the 5V rail and the at-spec 5VSB turn on spike. Once Topower is able to address these, they'll have a fantastic product on their hands.

The Good:

  • rails so stable I wondered if I had the SunMoon set wrong
  • very good ripple suppression on 12V/3.3V
  • almost Bronze level efficiency
  • extremely efficient at low loads

The Bad:

  • build quality could stand some improvement
  • hit the ATX ripple spec at 5V
  • average overshoot transient suppression

The Mediocre:

  • that big hole at the cable exit and no support for the wires coming through it
