    You can't go on wattage alone. You must look at the individual amperages on the rails.

    It's much like how one 1000VA UPS can handle 980 watts while another 1000VA UPS can only handle 750 watts. It's all about the distribution, not just the total wattage.

    So, maybe 100watts higher and it must be safe (in my situation)??

    Why not seems a more obvious question?

    But back to this posters needs- I have much higher power requirements than he does, yet a good 645W is all I need....

    I agree

    Thats correct I agree with you, In the past I have had problems with skimping on power supply units,(along time ago) But you are correct you can future proof your system by using a 1kw unit, and they are not that dear now days, The way the industry is going they will be main stream soon..

    Supermicro X7DA3 board with Quadro FX 3450.
    Supermicro PSU, runs like a charm and I have no need to upgrade it.

    I do realise that when I upgrade my 5140's to 54xx series that I will need to get the newer 800W PSU that they have available.

    What exactly will I notice different BTW? I have zero issues.

    The last place you should skimp is on the psu Coolermaster PSU's are very good according to many users I have the 1000w in my main system and a 700w in the second system NO ISSUES

    I had an antec psu for years with no issues but only 400w so its now my office machine's psu

    1000w is overkill indeed but future proofing was important to me
    In your case I would go for the 700w coolermaster to give you a little overhead and future proof that aspect of the new build! plus with a modular system its very easy to swop out the psu if you need to without unhooking all your drives power cables.

    Good on You

    Wow nine hard drives! I'll be buggered...what Board? I have been in the industry for 25yrs and I was a Development Engineer for Microsoft, All I can say is you must be running it just on the limits of the power supply unit, I run six raid drives, Twin 9650 quadro's, A Nvidia 5600 card, 3 burners, fans ect ect, All I can say is that 645watt power supply unit with what you said, I would never use. But in saying that it depends on what Quadro card you are using, alot of people on this site use very basic Quadro cards,, like people running Xeons that are designed for servers. Anyway good luck....
    P.S Try a 1KW one day and you will notice the difference I promise..

    cheers

    I have to disagree Steve,

    I have everything this poster has with 9 hard drives, BD burner + DVD burner, powered Quadro card and 2 Xeon's..... I have a 645W PSU and I have zero problems for over a year of intense workload.

    I used a PSU calculator from here and am within the limits.

    Mind you, I would add that Watts is not everything and that a well respected brand of PSU is very important too.

    1Kw

    Hi,
    My advice on this is to hunt down a 1KW (1000Watt) power supply, Reason is that if you go raid later on or decide to add a couple of DVD burners ect you will always have enough to power everything, Some people say that they are overkill but the bigger the supply the more stable things will be with your system, I use to use 750w and 650w and made the move about 12mths ago and have never looked back, Also check out Antec power supply units they are one of the best if you decide not to go with a 1kw power unit, I use a Silverstone 1kw unit which you will find here, http://www.silverstonetek.com/produc...p1000&area=usa


    Cheers

    As I mentioned in a other thread, I am going to build a new systeem.

    The parts in the systeem will be:
    Housing : Aopen H600B (re-use from old systeem)
    HD's :Raptor 150Gb +WD 250 GB Sata II (re-use from old systeem)
    MB :Asus P5K64WS
    Processor :Q6600 or Q9450
    Memory :Corsair TWIN3X 2GB DDR3 PC3-10666, 1333MHz http://www.corsair.com/_datasheets/T...-1333C9DHX.pdf
    Graphiccard : Asus 8600GT silent 512 MB http://www.asus.com/products.aspx?l1...00&modelmenu=1

    And the NX-express card.

    For powersupply I was thinking about the CoolerMaster Real Power M520 Modular http://www.coolermaster.com/products...detail&id=2685
    Will this be enough???
    Later on I am planning to put in 2 more HD's in Raid0.

    Please all advice is welcome (but my budget is limited)
