PSU Question HELP

my power supply is 500 WATT it sais that its got a continues rating of 400 WATT however I emailed Thermaltake and they said it will run at 450 WATT comfortably BUT everybody on the forums say 300-350 WATTS I don't understand; I looked on the side of the PSU itself, its got a rating of 400 WATT, max output of 500 WATT PLEASE TELL ME EXACTLY WHAT THIS IS!!

DC OUTPUT +3.3V +5V1 +12V1 +12V2 -12V +5VSB
Max Output Current 25A 28A 14A 15A 0.3A 2.0A
Min Output Current 0.5A 0.3A 1.0A 1.0A 0A 0A

PSU specs ^ (from website)

(Its a Thermaltake PSU, it came with my case; v4 black)
thanks

    I genuinely have no idea what TheNoobBuilder is talking about.

    As far as I can tell from those stats, you have a Thermaltake TR2 500W (W0093).

    PSU manufacturers have widely varying standards for how to represent their data. A really good PSU will understate it's maximum power because you'll be very unlikely to ever use it. It's important to understand that PSUs provide power at (effectively) three different voltages - 3.3, 5 and 12V. In the past more things ran off 5V but these days the two big components (CPU + graphics) both draw power from the 12V rail. More or less everything else: fans, HDD/SSD, disc drives etc all use a fairly small amount of power. What this means is that most good modern PSUs provide a high percentage of their power at 12V.

    Your PSU has two 12V rails of 14 and 15A, meaning it can provide a power (on 12V) of only around 348W. This is why people are telling you it is only really capable of 300W or so. The rest of the power is made up on the 5V and 3.3V rails, which are very big for a modern PSU.

    Thermaltake aren't exactly lying to you, that PSU can (maybe) deliver 450W of power, but it's in voltages you can't possibly use.
    A more accurate figure to use as a guide would be something around the 300W mark.

    Hopefully that explains things without getting too complicated.

    Hi - I think Rammy is correct - it is the tr2 500w, TT does not specify
    if those 2 +12v rails amps (14 & 15) can output max simultaneously,
    meaning that it might actually be less than 348w on the +12v rails.

    It is prob enough for your system as a gt640 sys requires only 350w &
    min 20a on the +12v.

    That looks like the specs for the Thermaltake OEM model 450W power supply model W0276. That's the model Thermaltake usually installed in the V4 Black version that included a PSU.

    On the PSU's label it states:

    Total combined +12V output load not exceed 23A.

    The OEM is HEC/COMPUCASE. Not a good PSU.
