Power Supply Advice needed
Hey all, I'm new posting here, but read a few threads and you are the people who can help me =D. I build my own computer a while back and have recently been adding onto it, but lately I am having a problem which I am pretty sure is the power supply. The problem I am experiencing is a random cutting out of all power in my computer, which forces it to reboot. I have made a temporary workaround in unplugging some power using devices, but I know it is time to get an upgrade in the power supply, however I am not really sure what size to get, or if my current size is good, and it is just crapping out on me. Listed below are my system specs, and hopefully you all can help me out.
P4 2.4 Ghz
3 Hard drives (One 60 Gig Seagate and two 250 Gig Western Digitals)
DVD Rom Drive
Radeon 9200 se Video Card
Creative Audio PCI Sound Card
PCI IDE Card
Currently all of that is running off of a 400W power supply that is a little less than 2 years old. This computer has been in use heavily for the full 2 years.
Once again, any help you all can offer will really be appreciated, and I look forward to your responses.
