    power supply for Mid Range System Leaderboard.

    I want to buy a POWER SUPPLY for Mid Range System Leaderboard.
    But I do not use the video card and not the sound card recommended.
    No sound card and my video card (AMD ATI's Radeon HD 5450 ) need less power then 10 watt.
    1. How much power my power supply need? Is 550 watt enough?
    2. Which company POWER SUPPLY is better, CORSAIR TX or ANTEC TP series?
    The only diff I notice is CORSAIR TX have the concept of not split up the +12V output, while ANTEC does split it.
    3. How much power in watt need the sound card ASUS Xonar DX 7.1?

    thank you

    I recently built a similar system. I have the i5-750 and ATI 4890 with on-board sound I used a Corsair VX550. It seems to be doing well so far. I am not a pro at this stuff. And wish I could have found this site before my build. I hope someone can give a little more info on this for us.

    550W is more than enough for your system. AFAIK, it doesn't matter whether you have single or multiple +12V rail.

    Looks like Antec TP-550 is a little better because it is 80Plus Bronze Certified, whereas Corsair VX550 is 80Plus Base. They are both good and reliable power supplies.

    You don't have to worry about Asus Xonar power consumption.
