    lights won't use much...so if you have a GOOD 450 [antec, vantec, ocz, etc], you should be ok. Just be sure and leave the x1800xt it's own strand.

    If you plan on keep adding lights like a maniac.... I'd get a 500 watter at least. Especially with an X1800Xt in there

    Please post the rest of your rig, and what you mean by a lot of lights. Also it would be good to know the make/model of your current psu.

    I would highly suggest you get a better psu if you don't have a quality 450w psu. the psu is the one area in a computer where I don't think you can ever go overboard (although can you anywhere else?) but seriously, you can have great components and if you do not have a good psu then the rest of your rig won't perform to it's potential. It looks like you've gone all out w/ your gfx card so you probably have a pretty decent rig. I would suggest you look for a high quality psu in the 500-600w range just to be safe. Keep in mind that there is much mroe to a psu than just the wattage rating!

    some good psu's to take a look at:
    Seasonic S12 series (500 or 600)
    Antec NeoHe series (500 or 550)
    Antec Trupower II series
    Enermax all in one noisetaker 600w
    OCZ powerstream 520
    Enermax Liberity series
    PC power and cooling 510 express
    Silverstone zeus
    Sunbeam Nuuo

    Who *NEEDS* a 650 watt PSU except an overclocker?

    Most 480 - 550 watt PSU's are more than enough if you buy a quality brand lol

    If you buy such powerfull card like x1800xt, you simply NEED TO OVERCLOCK! :D
    But if you wan't realy silence then go with Antec TruePower II.

    :lol: I'd agree.

    But even still.... I wouldn't think anyone would NEED a 600 or more even with a fully loaded system.

    Anyway, bigger powersupplies that are only at 40 - 50% of their load will likely be less efficient then a smaller one around 60 - 70% load

    While one may not need a full 600w psu, a performance system (especially an SLI rig) might draw 500-520w at 100%, so in regards to that a 600w would be ideal.

    most systems are perfectly fine with a 500w psu. However, I ran into some fluctutuation on my rails on my old 500w Aspire psu once I fully loaded it. (overclocked cpu and SLI) Also, for extreme cooling you really need a 550w + psu if you plan to run water pumps and fans or a pelter. to run that type of cooling you either need a really good, powerful psu or to run dual psus.

    What 450W do you have? What are the rateings for each rail on the label?
