  1. Any one? Please help..........
  2. yes, depending on the brand and other components in the system.

  3. I would guess that it would be ok as long as you don't have a ton of fans and a high power video card.

    80w chip
    70w mother board
    25w fans
    50w graphic card
    40w drives
    20w misc nic sound etc

    ~270w

    and most items only draw at peek usage. I'd think you would be ok...

    anyone else

    Complicated proofs are proofs of confusion.
  4. 300 watt PS is enough.
  5. System Overview:

    AMD Atlon 1800+ xp cpu/volcano or coolmaster fan
    FIC AD11 XP mobo with amd 761 chipset 266fsb
    PC 2100 256 ddr memory
    Sound blaster live 5.1
    generic modem
    Older dvd-cd rom drive...2 or 4x i believe
    Maybe one or two case fans...depending on case
    GF4 MX440 64mb ddr video card (Am trying to decide which maufacturer in graphics thread ...havn't bought yet)

    Thank you so much for your reply...I was beginning to lose hope last nite...went to bed and woke up to these new post!

  6. Please see "Power Suply Considerations":

    It depends of the current that your PSU can handle in each voltage (+12V, +5V, +3.3V). The Athlon XP 1800+ draws 6.87A from the +12V rail (that is 82.44W). There is a label in your PSU with its specyfications.
    Enermax and Antec are the best PSU brands.
  7. Not all 300W PSUs. Mine only supports 5.5A (+12V), 7A (+3.3V), I don't remember the +5V. I can't boot w/ my GF2 GTS + Pentium III 700MHz because of that (the GTS draws 3A and the P3 draws 10A from the +3.3V).
  8. About the MX440: get a card w/ 4ns memory.
  9. System looks good.....

    Im your keen on the GF4 MX 440 card...i recomend the LeadTek WinFast A170 DDR T.........I have one....its a really good budget card =)
