I would be careful about saying that. Considering one of your links is for a Rosewill P/S. Rosewill is one of the cheapest/low quality name brand makers there is. No more or less better than the Raidmax. Atleast Topower makes some of the Raidmax P/S. I would not suggest a Rosepop to a most unliked person.
I have used Rosewill and I have many friends that are not on here use rosewill too. And many of the Rosewill products are rated 5 stars.... Most of them are in the lower power rating power supply though.
Also, one thing you may want to know about me. If some company sells computer parts and the vast majority of them are low rated but they make one or two really products that are well rated with plenty of reviews, I'll go for the chance. I don't care about brand reputation, I care about the indevidual product I'm buying. That's why I would not use Rosewill for a higher end build.... because most, if not all of their hight wattage Power Supplys have marginal ratings. For a high end build, I would use something like Corsair, PC Power & Cooling, or maybe Antec or Thermaltake. But I will not buy something from any of them that is not rated 5 stars repetatively. And that's why I listed the Rosewill product I did.... The reviews were great with 5 stars repetatively, it had plenty of connections, had sleeved cables, good watts and amps, was stylish, and also very cheap in price (but not quality). I can't think of any other reasons not to get a power supply.
Oh, and topopower makes some of the worst PSUs I've seen. Many of them far worse than the "worst" Rosewill out there.
