Is my PSU enough?

    I just bough a new Seasonic 300w PSU for my system.

    My main concern is if it can provide my system with enough juice to perform well and run stable.

    Here is the setup:

    AthlonXP 2500+ Barton
    Vantec Aeroflow HS/F
    Asus A7N8X-Dlx rev. 2.0
    256mbx2 Corsair XMS pc3200 Ram
    WD Special Edition 80gb
    ATI Radeon 9500 pro
    Liteon 48xCDrw/16xDVDrom combo
    Sony 1.44mb FD
    ATI tvwonderVE PCI

    I'm also thinking of adding another HD sometime in the future, but that's not a sure thing.

    Anyhow, just wondering if that PSU can keep all that running well. Not an OCer, just normal user.

    You are right on the edge. I don't know anything about "seasonic" PSU. If you had an Antec or an Enlight I'd say your ok at 300W. With a name I've never seen tested you are pushing the envelope.

    If you keep the seasonic don't plan on putting anymore HD or CD/DVD's in. You might get by with more RAM.

    I agree with JeeJend.

    In your shoes, if you intend to add stuff into your computer now or in the future, I would consider at least 450 W PSU. That is just to be on the safe side.

    yeah, i would go with a decent 400w just so you don't have to worry about it being strained and voltages being off and wearing down your parts.

    but you can try the psu. it should be powerful enough to get it booted and stable (if it's not real cheap). and in windows, sue your motherboard's hardware monitoring software to keep an eye on the voltages. if any are off by 5% or more, then it could be an indication of a weak power supply. if any are off by 10%, then i'd get another power supply as soon as possible.

    Agreed as well. 300 is really pushing it. I would go with a minimum of 350. 400 or higher would be better.
  7. your fine, althoug if you were to upgrade to an 9800pro yod need 400watt minimum as i found out.

    Can anyone answer my friends question? I personally think it's not enough. I'd recommend a 400w absolute minimum but he wants more feedback about it.

    It really depends on the quality of the PSU, shaunj66. The efficiency of the psu is what dictates how much power you'll need. Someone above said he'd never heard of Seasonic power supplies, but in fact they are very good quality. In fact the Seasonic Super Tornado's efficiency rating is right around 75% (which is very good). I've never heard of an HEC power supply, so I'd say you'd need to up it. For most brands of PSU's, 300W would not be quite enough for your current configuration.

    Just so nobody gets misled from my original post in this thread system - common RAM size has gone from 256-512 meg @ 266mhz to 1 gig @ 400 mhz since my original recommendations and HDs of 120 gig are common now. So I'm upping my recommendations for power supply capacity significantly.

    The HD size doesn't make much difference but the extra 512-768 megs of RAM is a real power pig. 4-6 amps extra on the 5 volt output puts you over 20 amps. That kills a 300W supply and is pushing a 350 Watt supply.

    Add up the 1 gig RAM, 2 large HDs, the latest top end vid cards and all the USB connections (many power the usb device from the computers 5 volts) I wouldn't go with less than a 375W, probably a 400W now. And if your thinking overclocking or want one of the next generation Intel processors go for 450W. Intel has hinted that 100W for a CPU is acceptable (to them).

    If you have a 300W and don't want to have to upgrade don't max out the system with the fastest RAM around!

    If you mean the Antec TruePower430W, then you've made a wise
    This PSU features excellent current control. The voltage is regulated for each of the six main outlets and it has dedicated fan power controllers. Plus varispeed cooling fans
    .......mmmmmmmmmmmm ..quiet... slurp!.

    I upgraded to a 480WTruePower from a 350WEnermax, and the difference was instantaneous.
    Highly Recommended. You won't look back m8 :)
