Is this PSU OK? Here is my motherboard - yes it's a prebuilt computer. My PSU has recently been acting up, (I'm also sure that it's the PSU now, I asked on this very forum in fact!) so I will have to change a new PSU to my computer. My current one seemed to be a 550W one.

i7-2600 @3.4ghz
8GB ram
AMD Radeon HD6870

and this is the one I've been looking at:

I'm mainly concerned about if it even fits my motherboard. I think the power is sufficient - that one has 600W. I'm aware that the page is in finnish, but the main properties of this PSU are 150x160x86mm size, MTBF 100 000h @25c, power +5V 25A, +3,3V 25A, +12V1 25A, +12V2 25A, -12v 0.3A, +5VSB 2.5A (I've no clue what this means).

And the "wires", in lack of a better term:

1 x 20/24-pin ATX
1 x 8-pin CPU
1 x 4-pin CPU
1 x 6-pin PCI-E
1 x 6+2-pin PCI-E
4 x 4-pin molex
2 x Floppy
6 x SATA

So very simply, will this "fit" my computer? I'd hate to buy something that I can't use, naturally.

  1. well that is a standart atx psu and will fit almost all atx mobo's anyway. the thing is, you may want to be sure if it fits the case :)

    your mobos tech specs are here:
    and yes... 600W is enough for every system which runs single gpu.
  2. Its a standard PSU, so it should fit without any issues.

    I would recommend the XFX core Edition 550w
    Its cheaper, better efficiency,quality(Made by seasonic)
    And yes, its got sufficient power for your rig.
  3. For a system using a single Radeon HD 6870 graphics card AMD specifies a minimum of a 500 Watt or greater system power supply. The power supply should also have a maximum combined +12 Volt continuous current rating of 30 Amps or greater and have at least two 6-pin PCI Express supplementary power connectors.

    Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) rated at 45°C - 50°C ambient temperature, is the most critical factor.

    Overclocking of the CPU and/or GPU(s) will require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.

    The OCZ ModXStream Pro Series 600W (OCZ600MXSP) power supply, with its maximum combined +12 Volt continuous current rating of 42 Amps and with one 6-pin and one (6+2)-pin PCI Express supplementary power connectors, is more than sufficient to power your system configuration with a single Radeon HD 6870 graphics card.

    The OCZ600MXSP will protrude 20mm deeper into the case than your current OEM power supply unit. There should be enough room in the case to handle that.

    All of the power connectors that the motherboard needs are available on that OCZ600MXSP power supply unit.
  4. Thanks a lot guys. I'll take quick measurements to make 100% sure it fits my case. Thank you!
