Yeah, the sparkle 300W model FSP-300-60BTV and the Forton model FSP-300-60ATV are stout supplies, making nearly 400W in reality. They are very affordable and the only 300W supplies I recommend for overclockers. Most other 300W models just don't deliver like these babies, and can be problematic with a large load. A powerman branded version is available in the InWin cases that have 300W supplies, making them a top value in a moderately priced case.
The 300W FSP version is available from directron for $27. They also have the hoss 350W model for only $38. This beasty makes 450W in reality and is an even better deal. But even the cheapest 250W model is still a great supply, with 175W 3.3+5V output. The 200W 3.3+5V of the 300W model surpasses competing 300W units, and the 220W of the 350 equals that of the 431W enermax. Very conservative total wattage ratings on the sparkle/FSP's mean they compete with (numerically) larger supplies on equal terms. And even if you are building just one and want the best, these units perform at a level that merits serious consideration while at the same time leaving spare cash for that inevitable hard drive/motherboard/cpu/memory/video card upgrade that we all crave more often than can be admitted in polite company.
As an added note, I have used hundreds of these supplies in the last 4 years, and have seen impressive durabililty and reliability from them as compared to even the most expensive units. The supplies truly rock, and at the price point they are available at it makes no sense to have generic supplies in any machine you care about. And if you are a system builder like I am, the quality and value they represent gives your machine a great foundation in terms of quality at the same time it minimizes the possiblilty that you will have a mess to clean up down the road.
As noted above some FSP produced supplies may have a noisy fan in them. These are high quality NMB fans, and they move a lot of air in exhange. Fortunately they use standard 80mm fans as well as have no warranty stickers to prevent you from installing the fan you like best. I fitted a .15A fan in place of the .30A version in my 350 and enjoy the silence. Since the supply is just loafing even powering my big P4 rig the lighter duty fan is still very effective. If I were to RMA one of these supplies (something I've never had to do, knock on wood) I would put the original back in.
