    This power supply is actually somewhat of a surprise. While it is from Raidtronics, a company known for their bad power supplies, it actually works very well. It may be overrated some, I'm estimating it's actually a 500watt, but if you consider it at it's actual wattage, it's actually an excellent power supply as far as the quality of the output power is concerned. Also, keep in mind that it only has 360watts of 12v power, so there are sub-500watt power supplies that have more "usable" power than this power supply does.

    As far as the quality of the output power, this power supply has the lowest ripple(noise on the power output) of just about any power supply out there, better than Seasonic, better than PC P&C. Of course, as long as the ripple is comfortably within ATX specs, it's almost certainly not going to cause problems, so while this doesn't really give you any advantage, the amazingly low ripple on this power supply does point to this power supply being well designed. The voltage regulation is also very good, with the 12v rail not varying more than .16V throughout it's load range. Unfortunately, the efficiency isn't all that great, ranging from around 74% to around 77%.

    Overall, this is a nice power supply. As long as your computer can run with only 360watts of 12v power(most computers can, even gaming computers, but maybe not SLI'd 8800GTX's or Crossfire'd 2900's, and a quadcore CPU), this would be a fine power supply to use.

    As of right now, this is the only decent budget power supply on sale. I wouldn't be surprised to see StealthXStream or Earthwatts power supplies on sale for prices below this soon, so if you can wait a little while, you can get a better quality unit for a lower price.

    is this one better? http://www.newegg.com/Product/Product.aspx?Item=N82E16817341012

    I bought this one a week ago for $25 after rebate for my nephew. I am looking for a budget power supply to replace my Antec Smartpower 500W since its fan stopped running. I am using a Phenom II 720 and 4850

    Fans are cheaper than power supplies.

    The parts in this are ok for the price, but the manufacturing is a bit sloppy and likely to cause higher than average infant mortality rate.

    If it were a smaller rebate to get it down to $35, maybe a deal if you feel like powering it up before it's connected to anything valuable to make sure it's working properly.

    Yes, that's a fine power supply, definitely better than this Sigma one. You should have no problem using it in that computer. In fact, feel free to overclock if you'd like to, you've got enough headroom.

    I'm not surprised that your SmartPower stopped working, from what I've read those power supplies have a 25% failure rate.

    I think he created some of his "fans". Sort of like kids since we all know that's out of the question.

    CompWiz17 always comes up with pretty good recommendation on computer hardware and seldomly said anything bad about anyone in the forum. He doesn't deserve this kind of bashing. This is only a discussion, let's keep it civilized.
