Why should Corsair is recommend for PSU rather than other brand

I need a PSU that provides connections what i need, 2x PCI-E 6PINS (for high-end card 4800 series ATI graphic card), 1X SATA, 3X MOLEX

Why taking Corsair as a good choice, and others like powercooler are not since this has similar features.

  1. Similar features does not equal similar quality
  2. The Powercool 650 watt PSU puts out 30 amps on the 12 volt rails. That's about what a 450 watt Corsair PSU puts out.

    A 650 watt Corsair puts out around 50 ampson the 12 volt output. Plus a 650 watt Corsair will put out a bit over 750 watts before it shuts down.
  3. DellUser1 is correct. Similar features does not mean similar quality.

    I took a look at the two web pages you provided. Important technical information is missing on both of those pages.

    A high quality 500-550 watt power supply can easily power any single video card made. You do not need a 650 watt power supply for a HD 4800 series video card. Here is a link to a technical review of the Corsair VX550 power supply which comes with two PCIe 6 pin video power cables:

  4. which Watts should I get, just for overclocked ATI 4890 and overclocked newer graphic card with higher wattage use like 650W or higher. I only reply on single card since crossfire aren't supportable for all-around use.

    As mentioned by JohnnyLucky, the Corsair VX550 is plenty of power. There is no single GPU that uses over 200W, and most are less than 150W.
