    I have a p3 1 ghz, 512 mb ram, Asus mobo, cd-rom and a cd-writer, and got no x-tra fans, i'm going to replace my graphicscard with a Ti 4600 soon and i wonder if a 250 W psu is to weak for this system?
    Maybe I should have 300 W at least. The new card is a Creative 3d blaster.
    Btw, Anyone know anything about these cards? They are around 100$ cheaper than the asus card. /Thx

    Your PSU would probably be OK in your system. I'm running an Ath XP + lots of peripherals from a 250W PSU at the moment, and it's just holding in there.

    You may well be alright.
    At the same time you have identified your systems most likely potential weakness.
    So if you should experience problems, you know what steps to take.

    it depends on the power supply...most cheaper ones are much weaker than what they are rated at....when u get your new vid card keep an eye on your voltages with motherboard moniter 5....if say. your 12 V line drops below 11.9 you probably need a new power supply...also if u get random unexplained hangs it;s probably the psu:afro:

    The main problem is not so much the 12v rail but the combined 3.3v and 5v rails wattage that is the real deciding factor. :smokin:

    So how much should they drop before getting a bigger one?

    12v-12.22v
    5v-4.87
    3.3-3.28

    These are the loewst figures I got running pcmark2002

    Are these to low?

    I notice a few stutters here and there but I thought it was an XP/computer thing.

    Would you think I should considering upgrading?

    Look ya can give +/-5% voltage wise and that would make no difference but it's the amps/wattage that count the most as this guarantees the supply which in turn makes for a stable system. :smokin:
