    power issue


    Hello

    This is my Current System:-

    Windows 7 Home Premium x64 (fully updated)
    Windows XP Profesional x86 (fully updated to SP3)
    Zalman GS1200 Pro Tower Case
    Fractal Design Newton R2 1000W Modular PSU
    Asus Crosshair IV Formula
    AMD Phenom II 1100T x6
    Zalman CNPS9900-MAX CPU Cooler
    Corsair Vengeance 4x 4gb 1600mhz
    XFX Radeon HD6870
    2x WD 20EARS 2TB Sata drives
    1x Samsung Writemaster sata2 DVD ROM
    Netgear DG834PPN Wireless Router (Connected via LAN)
    2x200mm Zalman 'Built-in' Fans
    1x120mm Noctua NF-S12 (the Prototype of NF-S12B)
    2X92mm Fractal Design Silent Series

    I had a problem recently, my PSU stopped working slowly. so i bought
    this PSU 'http://www.quietpc.com/gb-en-gbp/products/powersupplies/fd-newtonr2-psus'

    my question:- is there a way to find out if my PSU is overtaxed
    (without external devices)?

    this info is taken from the bios on system startup/idle, will it help?

    CPU 1.323v
    CPU/NB 1.158v
    cpu/vdda 2.527v
    dram 1.574v
    HT 1.217v
    NB 1.118v
    SB 1.111v
    3.3V 3.312v
    5V 5.059v
    12V 12.158v

    thank you for your patience.

    it says 584W recommended but my last psu was 750 (3 years old) and it failed. I have upgraded to 1000W. the web-site says amps are justs as important as watts. can somebody explain that to me?

    Your power supply usually has a number of 12V rails and the amperage is split up between them. Some power supplies have a single 12V rail that has high amperage. A rail is like a circuit. Power cables from your power supply come off specific rails.

    The amps from a rail must be enough to handle the load you put on that rail For instance, you wouldn't want to run your graphics card and CPU/MB off the same rail - you need to balance the load across the rails. The amperage from a rail needs to be enough, say, to power your CPU and whatever else you run on that rail. For instance, my CPU, which will draw up to 185 watts, will need 185/12=15A and my graphics card can use up to 219W = 18A. The sum of the equipment you are powering off a rail mustn't exceed the maximum power available for that rail, which is 12V x the maximum current available for the rail. The power supply I have has two 22A and two 25A 12V rails ( which can supply 264W and 300W respectively) so I try and keep the MB/processor and Graphics card separate on the higher amperage rails and the disk drives on the lower amperage rails. Your PS manual should have the layout of what cables come from what rail and the current that each rail can handle like the snip below from my TP new 650W power supply

    It may have been that you hadn't properly distributed the power on your 750W power supply.

    so, my psu has a single 12v rail with a max 75amp.

    - Is that good?
    - Will it run a high-end gamers pc?

    Yes, 75 amps is very good and it will run modern hardware great.

    Its good unless something shorts That gives you 900W 12V total

    Isn't that a lot like saying, "sure, your house is a great investment... unless the earth opens up and swallows it". Why the suggestion it will short?

    Why buy some random PSU from a new to the market case manufacturer?. You should have gone for something from Enermax.
