    AC input 221/110vac 50/60hz 2/4a
    fuse pating:F 5a 250VAC
    DC +3.3v +5v +12v -5v -12v +5VSB
    Output 14A 20A 10A 0.5A 0.5A 2A
    MAX 400W

    I have now gone through three power supplies with this computer.
    Two when I plugged the cord into the power point first, then the computer, or just unplugged it from the back & plugged it back in ( I didn't realise this could kill one), the other when (according to my mother, she turned the computer on, then she tried to turn the monitor on but it wouldnt come on so she turned the computer off and on, then it just died)

    But on my dell computer, I can plug it into the power point first then the back of my computer and it doesn't kill it. Does dell have surge protectors or something on their power suppliess? Because if they do when I go shopping for one I want that. Can someone shed some light on this? + what watt psu do you think would be appropriate for my hardware?

    Well, 400 watts should be plenty, but you also need to consider the amps as well. If I am reading your psu specs correctly, you only had 10a on the 12v line. While your computer isn't a screamer, 10 amps is pretty low. If you live in the USA you can get a decent 350w FSP power supply from Newegg.com for about $35. It will have more than enough power for your rig.


    Also, you should always protect your equipment with a surge protector! You may want to check the outlet you have been pluging into and make sure that it is operating correctly.

    Yeah, I use a UPS. I noticed when I was plugging whatever into the back, mouse,keyboard etc if i touched the power cord it would "crackle". It doesn't on my dell machine though. I'm guessing it was just a crap psu.

    You could also have a bad power cable, but your PSU-specs point to a serious piece of crap!
    The 350W that nickslick pointed you to will work fine, however I would go to the 400W version of that same PSU, to have a bit more reserve.
