    Power Supply requirments Check

    ok guys,

    I've done some basic tests with a few power supply math websites but I thought I'd ask for the voice of expereince from you guys (I'n not sure if this belongs in modhouse so sorry if it does)

    I'm basically looking at

    Cooler Master Real Power 450 watt PSU

    as seen http://www.komplett.co.uk/k/ki.asp?sku=306517&cks=NWP

    I've recently udpated my PC with a fair few new components and I'll need to update my PSU also.

    Will this PSU give me more than enough (not just enough as I don't want to stuggle for the following


    1.) Asues Asus A8V Rev.2 Deluxe
    2.) 1 AMD FX55 CPU
    3.) 1 250 Gig WD IDE 7200 RPM disk
    4.) 1 200 Gig matrox 200 Gig 7200 RPM Disk
    5.) 1 74 Gig WD Raptor Sata Disk
    6.) 4 case fans with blue LED - 1 CPU fan with blue LED
    7.) one IDE cable with blue powered light
    8.) One UV cathode
    9.) 1 AGP BFG Nvidia 6600GT OC
    10.) 1 Adaptec SCSI Card
    11.) 1 Plextor SCSI CD Burner
    12.) 1 IDE Plextor DVD burner
    13.) 1 Sony DDS 3 SCSI Tape Dat drive
    14.) 2x1 gig Crucial Balistix Paired Ram
    15.) one coolermaster cooldrive 2 disk caddy (powered)
    16.) one floppy drive


    thats pretty much it, although I may stick in an additional 80 or 160 gig hard disk depending on your response.

    But will this PSU be enough (keep in mind the BFG Nvidia card and the AMD CPU)

    thoughts ?

    Do I need more ?

    will I be more than safe ?

    thanks,
    It is Inevitable.....

    Ive been told no less than 550W for a 64 bit system, but depending on the quality of the PSU. That might be ok, ive not got any experience with it though. I recommend to spend a good £100 or so and get an OCZ or Enermax PSU. If you think about it, you need to accomodate for future upgrades etc so its better to get a PSU that can handle all of your components. That rig listed must be the best part of £1200, so if your putting all that into a crappy PSU with not enough power ur asking for trouble!

    Have a think mate...

    A decent PSU like a Tagan 480w or a OCZ Powerstream 520w really for those parts

    With the amount of money you have invested in that rig, I'd get the best PSU you can afford. Something along the lines of the 600 OCZ. I'd reccomend more, but I'm from the other side of the pond and don't know what you guys have available here.

    Here's the manufacturer's page for this power supply:
    http://www.coolermaster.com/index.ph...LYReal%20Power

    Looking at those "continuity" figures on the 12v rails I'd be worried with all your drives that this would not be enough. I'd go for something over 500W myself from a reputable manufacturer like Enermax.

    great advice,

    I'm certainly not a tad wad - the PSU requirments "converter" webpages suggest 400w - 450 should be enough but it didn't seem write to me hence why I was asking in here, a top notch 600 - 550W would be magic but it didn't seem right to put one of those in when all the converters where coming up with 400/450, it just didn't seem right though.

    thanks for the tips,

    power supply hunting now.....

    I don't see why one computer system will need 600Watts... (That's 0.6 Kilowatts)

    Why wouldn't a decent, reliable and stable 400-480W one do the job?

    Howard - If you mean why am i buying it/similar..... the new rig will be SLI 6800GT's with AMD64, 4 hard drives, 2 opticals, i'd rather get as much power as possible.

    that was the way I was thinking get too much power rather than devices struggle
    I think I'll go for the OCZ PowerStream 600w ATX2.2 Power which helps you tune the PSU your for you PC settings.

    Seems a good choice

    TBH the only time your rig will be drawing anything like 400W is when it's booting up and all the drives are spinning up. I'm pretty sure it'd run fine from a 350W PSU the rest of the time- but a computer's no good if you can't get it to post

    that'll sort you with enough power, to go get the next few versions of windoze twenty years from now, and release them ahead, thus beat the competition

    Let's not forget that manufacturers figures are not always what they seem. At least Coolermaster have been upfront about the power loss when the PSU heats up. I think you should be looking at 30%-50% headroom on what your calculated power use comes to.

    On that basis 400W becomes 520-600W...

    So many weird and wonderful computer problems are caused by weak or underpowered power supplies. IMHO 350 watts with a modern system is just not going to cut out. With a bleeding edge system (especially with 2 high end video cards) 500 watts would be the bare minimum I'd want. While that may be overkill, I wouldn't want my powersupply running at or near its peak on a continuous basis, I'd prefer to have that margin of error.
