Bjorn3D have a review of the Ultra X4 500W power supply, which comes with a lifetime warranty. If you have a high end graphics card, this may not be enough power:\n \n[QUOTE]For many of you 500 watts is plenty enough. Instead of investing more money for a higher wattage PSU, you can spend less, and still get the power you need, but spend more money in other places. In the current economic times this can be the difference between a low end graphics card and a mid range one. Thus your gaming experience will be much more enjoyable. If you fall into this category then you can finally breath easy, for Ultra has your back.\n\nNot only is Ultra a reliable manufacturer of PSU, but they also back their PSU's with an amazing lifetime warranty. When a company backs their product with a lifetime warranty you really know they not only care about the consumer, but their product as well.\n[/QUOTE]\n \nRead the review [URL="http://www.bjorn3d.com/read.php?cID=1766"]here[/URL].
