    Look Here If Buying A PSU or find how much power you need

    Look Here If Buying A PSU

    This was found by my clan member carlos 1of9 from the Alpha 9 clan.
    A great tool to find how much power you need or should have to run your PC.

    Power Supply Calculator http://www.jscustompcs.com/power_supply/

    Our New & Improved Power Supply Calculator is here! I want to thank all of you who have emailed with your input over the past year. The Wattages listed below are maximum peak wattage for each component.
    The total amount this calculator figures is for all devices running at peak utilization. It is important to bear in mind that this amount will never be reached under typical operation. However, I feel that this tool will give you a better idea of how much power your system will need. After all when it comes to power, having excess wattage on a power supply is never a bad thing!

    Also, one other important factor is the amperage of the +12V rail. A good power supply will have a beefy +12V rail (18A or higher), or even dual +12V rails, as Antec does with their TruePower series. Also, beware that there are many 'imposter' power supplies on the market right now. I have seen power supplies labeled as 500 watt, when they are actually only 250 watts. There are three ways to tell if a power supply is labeled correctly, 1) Check the amperage on the +12V rail, 2) Check the price. If it claims to be 500 watts, but only costs $30, that should throw up al kinds of red flags to you. A true 500 watt power supply will cost between $90 and $140, and 3) Buy a brand name power supply. There are many knock-off supplies out there. Do a little research on the brand. Most 'imitation' power supply companies have no website or a very poorly done website.

    These are peak wattages. Even under full load, actual consumption is usually less than these figures.

    A nice tool indeed, but it's getting outdated.. Highest video card is the 6800Ultra, can't find my 7800gt in there :/

      7800's use less power than the 6800's did. Just use the 6800ultra and you are more than covered.

          Yeah, I bought a Vantec Stealth 420w, and it blew my previous "500w" cheap-o PSU out of the water. It's so lame what they try to get away with. Very nifty tool, btw. I'll probably use it just to be on the safe side when I build a new system, although I usually just figure it on paper.
