I'm building a computer for my brother to replace his old desktop. All i'm asking is, will a 300 Watt PSU be ok for this build? I'm not buying the PSU, it's one out of another PC.

Your question is meaningless without ALL the specs related to the PSU. And knowing the brand name would be helpful too. If the answer is YES to the following questions, it *should* work...no guarantees though: - does it have a 24-pin main ATX plug? - does it have a 6-pin PCIe plug? - does it have at least 30A on a single +12 rail? - if it has dual +12v rails rather than a single, are they at least 18A each? BTW, poor motherboard choice, plus DDR2-800 is the wrong RAM to be running with a Kuma. To make the most out of it, you should get DDR2-1066 but you'd also need a board that supports it.

I'll get more information in a few hours and repost. Thanks for the input. Always very quick and helpful, Jam. Abit AN8 AMD64 X2 4200 @2.5Ghz Corsair 3Gig Dual-Channel 2x512 2x1gig MSI R4830 Seagate 160Gig SATA Seagate 320Gig SATA External 1T

there are a few components I'll reuse when I rebuild, but the PSU isn't one of them, just because it can be approaching the end of its lifespan, even start underpowering components, before you start to see symptoms. good advice has always been not to buy cheap PSUs, and i think the same rational can be applied to questions about reusing old PSUs...
