If you are in the market for a 750W power supply then I highly recommend the Corsair TX750W and even if you don't need all the power, it's still worth considering for your next build. The price, at the time of writing this article, makes the Corsair TX750W excellent value for money. The Corsair TX750W is Nvidia SLI certified for dual 8800GTX graphics cards and if you intend to start off with a single graphics card and upgrade to SLI or Crossfire sometime in the future, then consider using the TX750W, you won't regret it.
