    <div style = "color: #FFFFFF; background-color: #EEEEEE;">A new power supply reference guide has been created to replace this thread. -----------moderator-------------------

    As requested by a few members, I have compiled a final list, which breaks off of a much longer thread, and have made it into this "final" list. This will hopefully serve as a guide to anyone not sure on whether their PSU is good or bad, or for recommendations to builders.

    Refer to linked thread!

    Also, in case you are interested in what size power supply you need, I have included a calculator, and a guide that should give you some idea.

    However these over estimate the power needs quite often, most current systems can run quite well on a good 350W PSU. When you start to get into the higher end systems, with the A64's, and in the future the X800 cards, etc., you will want to up the wattage.

    Here is a guide describing what process you should go through, and things you should look for when buying a PSU.</div>

    Leave yourself about 30 percent headroom. Actual output goes down as heat goes up.

    Why hasn't this thread stickied with the number of power supply questions on this board?

    No, and it was suggested/requested that the thread be "redone" with a final list in hopes that it would be stickied.

    The problem is that not very many mods come through this forum on a regular basis.

    Hey, bigandy. Why not post another thread in the case modding section with the same title and link it to here? Nice job, btw. Copied to Notepad for my future reference.

    Power supply

    I'm brand new to all of this. I have so far purchased:
    A7N8x deluxe v. 2.0
    AMD Athlon XP 3000+ 333FSB
    Powmax case w/ 400watt.
    After reading that my power supply is bad, am I going to ruin my hardware or something? I'm on a pretty strict budget from my wife and still need to purchase memory, hard drive, video card etc.

    Advice please

    Think it's a predictability problem. No one can say for sure that your power supply will fail. But that brand has a higher incidence of failure than those on the good list. If/when it does fail again it's hard to predict what will happen. Sometimes the power supply just stops working. Other times it may create a power surge and take several key components with it. Buying a higher quality power supply is like buying insurance.

    FSP Group is Fortron Source. The box says FSP Group INC. The website is FSP Group Inc. and the psu says FSP Group Inc. however; the right under it on the psu you can see "FORTRON/SOURCE" I was a bit confused myself. Perhaps big daddy might be kind enough to include "FSP Group" as fortron source to prevent some more confusion :)

    It's disturbing to see that there are nearly as many bad ones as good ones. I'll bet there are tons of prople that don't even know what brand they have.

    I think the word "bad" is misleading. Maybe a better word to use is "cheap". All computer coponents come in wide ranges of quality. And sometimes cheap and bad don't mean the same thing. I mean, I bought a 10 dollar kensington keyboard. Is it bad? I dont think so; it works well enough. But its cheap compared to a higher priced and better quality logitech keyboard.

    A lot of those "bad" psu's will work quite well in simple or older rigs. (some more-so than others... I wouldnt put a DEER in my ancient 386; its taken enough abuse over the years.)

    Most of your retail computers (just about all retail computers a year or older) come with cheap psu's like the one's listed.

    So again, bad should probably say or atleast translate as "cheap". Those are the psu's you probably wouldn't look for if you want to spend 1200+ on a large rig.

    Thanks for the help. I'm sure I'll need a lot more before I'm finished. Now back to the web and more shopping.
