    Trying to find out how much watts do i need for my new hardware.

    Hello there, I am about to buy some new hardware for my computer.

    1) AMD Athlon 64 X2 6000+ Windsor 3.0GHz AM2 125W
    2) GIGABYTE GA-M750SLI-DS4 AM2+/AM2 NVIDIA nForce 750a SLI ATX AMD Motherboard
    3) CORSAIR 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400)

    …but, i am worried about how many watts in power do i need to go ahead with the upgrade. The processor alone is 125w. My old Athlon is only 65w. I tried to do online power calculations, including this one: http://www.journeysystems.com/?power_supply_calculator

    but it seems they are so out of date. This one doesn’t even have my processor as an option, so how can i trust it. So one of my questions is: What happens if there is a shortage in power, if my hardware requires 500w power and i only have 400w power supply. The computer just will not boot up?!, or do i get all kind of errors, blue screens of death and other stuff while using the computer?

    And lastly, if anyone has this similar configuration that i am about to upgrade to, pls share your opinion on how big a power supply should i get, i have a 500w wight now, i was thinking maybe getting a 800w or something, but again i dont wont to over do it, and just spend money for no reason.
    here’s a total of what is going to be under the hood:
    —————————————–
    1x the above procesor
    1x the above motherboard (GForce 8 series video card included)
    1x the above RAM combo (2 x 2GB sticks)
    1x DVD-Drive
    1x DVD-RW drive
    2x SATA drives at 7200rpm
    1x ATA133 drive at same speed i think
    4x colling fans including the processor fan
    1x wireless PCI card
