    PSU question...

    Hi all....

    I recently received a system that I am, in turn, giving to a friend of mine. One time while I was working on it, the system suddenly shut down and rebooted. I had just installed a fresh copy of XP and installed the latest drivers for all the devices, including the chipset drivers for the Intel D945PVS motherboard. Thinking that didn't bode too well, I performed tests on the motherboard and the memory, which turned out ok. When I got to the PSU, it gave me a p.g. value of 990ms or over. Combine that with the random reboot, I'm thinking it's a good time to replace the PSU.

    It's rated at 350 watts so I'm wondering if I purchase a replacement that is 500 to 900 watts, is that going to overload the motherboard or any of the other components and start burning or melting stuff? Otherwise, it's a good working system, although an additional 512 MB's of memory wouldn't hurt it.

    Also, any personal opinions and/or experiences on good quality and reliable PSU's, besides PC Power and Cooling?

    Thanks!

    In my opinion, you can't go wrong with a Rosewill or Antec PSU.

    I found this newegg tool helpful when it came time to upgrade my PSU. Plug in your specs and it will give you a pretty good estimate of the amount of power you need. That way, you won't have to waste money on extra wattage.

      Thank you

      Any thoughts concerning my first question in case I have to purchase one with a higher wattage?

        The PSU won't over-feed any component. The ratings are a capacity limit, not a constant.

        It's less like a garden hose and more like a tank - It gives you what you draw from it, but stops flowing as soon as you stop drawing.

              I don't really agree with limiting your PSU to only what is necessary to run the computer. Who knows what components may be added to that computer later. When it comes to PSU's, more is always better. A gripe I have about PSU's is that many of them now come with the cooling fan pointing down and blowing into the computer case. I modified my case so that I could mount the PSU upside down and drilled holes in the top of the case for ventilation.

                Precisely -- I totally agree, based on considerable experience.

                  Detonate - my last couple of cases had the PSU at the bottom, thus the fan blows outside the case. This might be the new trend? Makes more sense in a floor setting case.

                  Simple matter to reverse the fan in your PSU by flipping it over - after the warranty expires of course!
