    Ive bought corsair cx400w and it shuts down after 15 minutes of use, could this be from overheating? The old psu is working fine but is too loud.

    Temps:
    CPU E7300 2.6GHz 36C Core2:40C on idle
    MB Asus P5B :40C
    Asus 9600gt :44C
    Two Hard drives: 36C

    Ive connected the psu outside of the case and it was working fine for 1 hour before I turned it off.
    Also i have tried the paper clip test and it didnt turn on, only made one spin on both fans(psu fan and case fan)

    Can the psu fail the papper clip test, but not be faulty?

    When it shut down wat were u doing on ur PC?

    And why did you buy a 400w PSU for your rig? It's not enough power.

    W/ out more info I'd say it's tripping over-current protection - your post is a little confusing.

    I was just browsing the internet and listening music. I think 400w should be enough, the psu calculator it says my system should be around 300w at full load, everything is at stock voltages.

    You sure it's the PSU and not the CPU shutting down?

    If the PSU is shutting down it's most likely due to overloaded rails.

    Im sure its the psu because it works fine with another psu. What confuse me its that the psu works fine when its outside of the case but also cant start when shorting the green and the black wire on the atx connector.

    If it works fine outside then it might be overheating. Still points to an underpowered PSU.

    A PSU can overheat from constantly supplying it's max output power. They need room to breathe, so to speak...

    You shouldn't get a PSU that can barely keep your system running, because it might overheat, they aren't really designed to be under max load 24/7, afaik at least.

    Yeah some PSU's won't paperclip jump start without a load on some rails sometimes but it's rare and even a lot of PSU's that list a minimum load output of like 1A will still spin up but may not keep output voltages in spec is all...but alot of times a PSU that I've been torturing to near death will begin to not want to start up without certain loads too. Sounds like you got a defective one to me.

    Sounds like a defective PSU, the rest of the temps in your computer seem more then acceptable and not likely to cause overheating and 400 Watts is more then adequate for that system as well.
