I've never had either of these, but at Newegg I saw subtle differences in at least the 300W version, the PowerQ series doesn't appear to be the same, slighlty different specs (though that could be a typo?) including different external casing and crappy Yate Loon fan... it's NOT just a different label on 'em, but perhaps otherwise the same design from different factory? Usually a junk fan spells trouble, an indicator of the total construction budget being lower, not just a 20 cent savings on the fan.
What's the significance? Sparkle has made some relabeled low-end stuff in the past, reserving their "Sparkle/Fortron" name on the labels of better units. It would be very helpful if someone with a regular Sparkle of same wattage could thoroughly compare one of these for us. In particular some of the generic-labeled Sparkles from past years had crap fans too.. several times I received dead systems where those !@##$ Yate Loon fans had seized then the PSU baked till the caps popped or a diode went out. If you have to spend $5 to replace the fan yourself you might as well buy the regular model. No vents on the underside either... that was one of my favorite things about the 300-350W models, that they could move a lot of air quietly.
These might be best used for someone you SELL a computer to, one of those "quality be damned build me the cheapest box possible" type buyers, where you need a power supply that can put out enough power to keep the system going till the cheaper fan, caps, or whatever, fail in a couple years... or I could be completely wrong. I'd rather spend the extra $10 on Sparkle or Fortron labeled units, though these days I'm wanting name-brand 400W for anything modern and near future.
