I had a problem a while ago with the original power supply I bought with my case. Being that it was a P4 400w powersupply I thought it would work perfectly, but then I noticed a problem. The extra 4-pin power connector was differently shaped than the extra 4-port power socket on my motherboard. I figured it was a P3 to P4 difference thing and forgot about it.
Then i found my computer off one day (i never turn it off) so I thought it had crashed, but it ceased to power up. After several tests, I yanked the 250W power supply from my old AMD k6-ii 400, and voila, the system worked. I knew I would order a new power supply soon and as I am in the market I was wondering about suggestions, for the "type" (so that the full 24 pin connector can be used on my motherboard) as well as power needed to run my system.
I had a second question, that is less important, but wondering if my system could being affected to the point that it causing games that worked on 2kpro not to work on xp, after upgrade & reinstall, or other such glitches with game/video crashing that happens on both 2k & xp could be caused by a too low power output by my power supply.
