Possible power problems/unusual

  1. Possible power supply problems?

    Hi guys, i'm having a major problem with my computer, just wondering if you guys can help?

    Last night I was using my computer as usual, was running without any problems. Suddenly the computer just powered down, turned itself straight off, and was like a power cut. I left it until the morning when the computer still failed to start. I then started to try and isolate the problem, unplugging unnecessary parts ETC. I suspected it was the processor as this has happened before. However, I am able to start the computer up, but only with a maximum of 2 hard drives connected. In order to get this to work I have been forced to unplug the third hard drive, my 2 DVD drives, my floppy drive and a case fan. Other combinations work, but it seems only 2 drives can be connected at any one time. When it doesn’t power on, everything starts up for around 3 seconds and then shuts down. It just doesn't make sense as my computer has been working fine for over a year without any problems in this configuration, and over 18 months before that. I am at a loss to explain why the system would suddenly appear to require more power. As I say I really have no idea, has anyone experienced anything similar or have any idea what's going on?

    My computer spec,

    Motherboard - A7N8X Deluxe with an athlon XP 2700 +
    550 watt PSU
    3 Hard drives, 2 SATA
    2 DVD/CD rom drives

    Surely someone must have an idea?

    Certainly seems like a degraded power supply. By one with a larger wattage, this one might have been borderline.

    That was definitely my thought, but at 550 watts it should have been more than enough surely?

    (Watt is the unit of power?) :haha:

    Yes, it seems to be the power supply. Either to weak in the first place, or a cheap one, in which it gives less wattage then stated.
