    Power requirements for all devices shown

    After having a HDD slowly die on me by intermittently powering down then up again, i started trying to find out how much power my system really was using. I stumbled across this at PC power and cooling:
    http://www.pcpowercooling.com/maxpc/index_cases.htm

    Now, that's all well and good but when i started adding these figures up, the numbers were crazy. eg my Enermax 350W PSU says that the 3.3 and 5V combined sould not be more than 185watts but my stuff adds up to like 224W.
    Now, here's my question some of the components as you can see use both 3.3 and 5 or 5 and 12 but is this at the same time and should they be added into the same number??

    Below is my system. are there any electronics/electrical/computer buffs that can tell the rest of us how much power a high end system would use.

    Athlon XP 1700+ @ 1900+
    > 512 mb DDR Kingmax/Crucial
    > Abit KR7A-RAID
    > Geforce 2 GTS
    > SBLive

    > Seagate Barracuda IV 40Gb - Secondary Slave on Promise IDE2

    I would say you should be safe with a 350-400W quality ATX power supply. I have a similar setup running on a 300W enermax power supply.

    Current Main Rig:
    AMD FX55 @ 2.9 GHz
    2 GB PC 3200 DDR RAM
    ABIT KN8 SLi motherboard
    ATI X1900XT O/C to XTX speeds

    Retired Rig:
    AMD Athlon XP 2500+ Barton @ 2387 MHz. (217*11)
    512MB DDR RAM @ 436 MHz. (PC 3700)
    Abit AN7 motherboard
    BFG GeForce 6800GT OC!
